What I Build and How I Work

Everything listed here has been delivered at least once. Most of it ships in hours or days.

How to Read This Page

If you want the full picture, I can't give it — I haven't found the walls yet. But this is what I've done recently. I have 20+ years across healthcare, payments, and enterprise IT, but I've been most productive in the last 18 months with AI. Where I'm strongest is taking an idea and making it into an actual thing — a prototype, a full product, or the business case and architecture that gets you there. The pattern is always the same: take something that's confused, give it structure, build it until it's clear.

What I turn into structure
"I have an idea but I don't know where to start." "We know what we want but can't articulate it." "We've been talking about this for a year and nothing has shipped."
What ships
Business case with real financials. Requirements that can be built from. Architecture decisions that won't need to be relitigated. A working prototype. Sometimes all four in the same week.

Zero to One: From Idea to Buildable Plan

The hardest part isn't building. It's knowing what to build.

Most engagements start here. A founder, executive, or department head has a vision and no clear path to execution. I sit with the ambiguity, run the discovery, and deliver a plan that a team can execute against.

What I Deliver

DeliverableWhat It AnswersFormat
Business CaseIs this worth building? What's the market? What does break-even look like?Document + interactive financial model
TAM / Market SizingHow big is this? TAM/SAM/SOM with sourced data, facility counts, pricing tiersDocument with data tables
Unit Economics ModelIs each customer profitable? At what scale? What are real COGS?Interactive web tool (shareable URL)
Competitive LandscapeWho else does this? Where's the positioning gap?Multi-vendor matrix with quadrant
Product ScopeWhat are we actually building? Phased, with estimates.Scope doc with story-point estimates
Architecture Decision RecordsWhy this stack? Why this approach? What were the alternatives?Structured ADRs (100+ across projects)
Working PrototypeCan we react to something real instead of a slide deck?Clickable demo or deployed MVP
How this typically works: A founder walks in with "I want to build X." By the end of week one, they have a business case, interactive financial model, competitive landscape, and a phased scope document they can share with investors, advisors, or a board. The prototype follows. One engagement, one thread, from napkin to production.

I Am AI-Native

Humans architect. AI executes. Architecture is the prompt.

This is not "I use ChatGPT sometimes." AI-native engineering is a discipline where humans define architecture and AI executes implementation, governed by persistent knowledge infrastructure that compounds across every session.

The scarce resource is not coding speed. It is architectural clarity. AI performs best inside clearly defined boundaries. The system design determines the quality of the output. That's why every engagement starts with structure, not code.

The Model

Traditional: idea -> meetings -> spec -> meetings -> code -> meetings -> ship AI-Native: problem -> constraints -> architecture -> AI execution -> verification -> deploy The difference: Human does the 20% that matters: asking the right questions, making trade-offs, understanding what the client actually needs vs. what they said. AI does the 80% that is mechanical: research, first drafts, implementation, formatting, test writing, deployment.

What This Means in Practice

Traditional AgencyBert Carroll (AI-Native)
3 SP task: 8-16 hours, $1,200-4,0003 SP task: delivered same day, $300-600
Business case: 2-3 weeksBusiness case + interactive financial model: 1 week
101-page product demo: 2-3 months101-page product demo: 1 week
One-pager: graphic designer + copywriter + review cycleOne-pager: 15-30 minutes, mobile-responsive, view-tracked
Spec review: consultant + 2 weeksSpec review: 2-3 hours, shareable URL, color-coded gaps
Meeting prep: "I'll look them up on LinkedIn"Researched bios, soundbites, coaching notes, checklist: 30 minutes

AI Capabilities I Deploy

CapabilityWhat It Does
Agent OrchestrationSpecialized AI agents in parallel: research, code generation, security review, test writing. Human directs, AI executes.
Clinical AI (Orbie)Conversational assistant for clinicians. Patient triage, engagement summaries, interactive charts. Zero-trust RBAC, full audit trail, global kill switch.
AI Treatment NotesClinician dictates 2 minutes. AI structures into SOAP/DAP/BIRP/GIRP. Billable note in under a minute. 90% time reduction.
Requirements ExtractionUpload a referral packet, RFP, or spec. AI extracts demographics, requirements, gaps. Human validates.
Knowledge CaptureEvery session produces knowledge artifacts, not just code. Mistakes become guardrails. Decisions compound. 100+ ADRs across projects.
Non-negotiable: I use AI to accelerate everything I do. If the client isn't on board with that approach, they should hire a traditional agency. I don't do traditional speed at traditional prices. That's not the offering.

Orbiit Recovery Platform

My flagship product. Between-visit recovery support for behavioral health.

Orbiit is a live, HIPAA-compliant platform I built as CTO and co-founder (25% equity). Concept to production MVP in 68 days. Django + PostgreSQL + Azure. Multi-stakeholder RBAC across 5 user roles. AI treatment notes (90% time reduction). 49 architecture decisions documented. This is the methodology applied to a real product in a regulated industry.

Strategic Services

Strategic Services

Project-based and advisory engagements. 20 years of BA, governance, architecture, and compliance across regulated industries.

Business Analysis & Requirements

20 years of BA discipline. $2.17B healthcare AR. $1B+ payment portfolio migrations. BA team leadership at a $370M public company.

Before I was a CTO, I was a business analyst. That discipline didn't go away when I started building. It got sharper. Every technical decision has a BA foundation under it — requirements, process maps, gap analysis, data modeling, spec reviews. The work below shows what that looks like in practice.

Deliverables Shipped

Gap Analysis
302 SP Production Gap Analysis
101-page demo mapped against production requirements. Every module graded, every gap estimated, phased delivery plan.
Spec Review
Section-by-Section Spec Audit
Collapsible sections, color-coded badges (Done/Partial/Not Built), metrics dashboard, shareable URL.
Process Map
Clinical Intake Workflow
15-step patient intake from referral to treatment plan generation. Decision trees for insurance auth, bed availability, level of care.
Data Migration
Payment Portfolio Migration
$1B+ merchant portfolio. Source-to-target mapping, business rules, pilot validation, phased rollout plan.
Where this came from: Fresenius Medical Care (healthcare technology), AT&T (enterprise systems), i3 Verticals (Atlassian practice lead, BA team manager at a $370M public company). Production BA work in regulated industries for two decades.

IT Governance & Business Cases

Business cases, decision frameworks, build vs. buy analysis, project visibility

The work between "we have an idea" and "the board approved it." Building the business case, establishing governance, and making sure decisions are documented and defensible.

CapabilityWhat It Looks Like
Business Case DevelopmentProblem statement, solution options, financial projections, break-even analysis, risk assessment, recommendation. Board-ready.
Vendor EvaluationBuild vs. buy analysis, RFP/RFI management, vendor scoring matrices, contract review support.

The Signal System

I built my own project visibility tool. Every active project gets a live dashboard at ath.how. ROADMAP.md drives the dashboard. AI updates status on commit. Clients see exactly where their project stands.

Background: Wrote PMO operations guidelines, managed multiple concurrent projects as BA lead and IT manager. The governance instinct comes from running the work, not from a PMP certification. Every process earns its place by answering a question someone was already asking. If nobody reads the report, the report shouldn't exist.

Process & Tooling

Confusion to structure to clarity. Whether you're stuck or just want something built fast.

Two kinds of clients end up here. Teams that are trapped in process designed for a different era, or have no process at all and everything is on fire — I fix that. But also competent organizations that just want something built fast with no overhead. They have a working team and a clear need; they don't want to spin up a 6-month initiative to get it done.

The pattern I apply everywhere: confusion -> structure -> clarity Not by adding process. By making the existing chaos legible. Information already exists. The gap is always distribution and decision-making.

What I Fix

SituationWhat I Do
"We have Jira but nobody trusts the data"Workflow redesign, field cleanup, automation rules, dashboard rebuild. Former Atlassian practice lead at i3 Verticals ($370M public company) -- I know what good Jira looks like.
"Nothing ships"Diagnose where work stalls. Usually: unclear acceptance criteria, no estimation discipline, or stories that are actually epics. Fix the inputs, not the ceremony.
"We have no process at all"Right-sized structure for the team. Not Scrum. Not SAFe. Estimation, prioritization, and visibility calibrated to how the team actually works.
"400 items in the backlog"Prioritization (value/effort). Decompose epics into buildable work. Archive the noise. Make the backlog a tool, not a graveyard.
"Documentation that nobody reads"Take what's in repos, wikis, and people's heads and put it where stakeholders actually look. One-URL shareable pages replace slide decks, status meetings, and email threads.

Tooling Background

ToolExperience
Jira / Confluence / BitbucketLed the Atlassian practice at i3 Verticals. Migrations, consolidations, workflow design, training, team management.
Signal (My Own)ROADMAP.md-driven dashboards. AI updates on commit. Live at ath.how.
Story PointsI price work in story points, not hours. The estimation discipline is battle-tested because it's how I get paid.

Story Point Pricing

Story points are additive. A project is scoped as a collection of estimated tasks, not a single number. Most new engagements start at $5k minimum. For existing clients or retainer relationships, I'll take on smaller one-offs — landing pages, funnel pages, surveys, sales collateral.

8Very LargeMajor feature, architectural refactor, multi-system$800-1,600

Technology Strategy & Architecture

Stack selection, architecture review, build vs. buy, technical due diligence, migration planning

Capabilities

CapabilityWhat It Looks Like
Architecture ReviewEvaluate existing systems for scalability, security, maintainability. Identify technical debt and prioritize remediation.
Technology SelectionStack evaluation with ADR-documented rationale. Framework, database, hosting, auth, payments. Decisions that won't need to be relitigated.
Build vs. Buy AnalysisTotal cost of ownership analysis. When to use SaaS, when to build custom, when to integrate. Vendor scoring with weighted criteria.
Technical Due DiligenceFor investors or acquirers evaluating a technology company. Codebase review, architecture assessment, team capability evaluation, technical risk identification.
Migration PlanningLegacy-to-modern migration roadmaps. Source-to-target mapping, data validation strategy, parallel-run periods, cutover planning. Proven on $1B+ payment portfolios.
Security AssessmentApplication security review, threat modeling, OWASP top 10 audit, authentication architecture, data protection strategy.
AI Integration StrategyWhere AI adds value vs. where it's a gimmick. LLM selection, prompt engineering, agent orchestration, cost modeling, build vs. API decisions.

Architecture Decision Records

Every major decision gets documented with context, alternatives considered, and consequences accepted. 100+ ADRs across active projects. This is how you build auditable technology organizations.

Production stacks I've delivered on: Django + PostgreSQL + Azure, Astro + Supabase + Cloudflare, React + Node + Netlify, Azure AD B2C, Twilio, Stripe, Plaid, Coinbase. These are production systems handling real users, real data, real compliance requirements.

Compliance & Regulatory

HIPAA, PCI-DSS, TCPA, COPPA, FERPA, state-specific regulations, FinCEN MSB

Compliance is architecture, not a checklist. When you build it in from day one, the audit becomes a documentation exercise, not a fire drill.

Capabilities

CapabilityWhat It Looks Like
HIPAA Compliance ProgramsFull security rule coverage: administrative, physical, technical safeguards. Policy library (21+ policies), BAAs, incident response, workforce training.
Policy DevelopmentVersion-controlled, audit-ready policies with review cycles, approval workflows, and automated reminders. Git-tracked.
Audit PreparationPre-audit readiness assessment. Gap identification, remediation tracking, evidence collection, examiner-ready documentation.
Regulatory ResearchState-specific regulatory mapping (e.g., 131 Georgia DBHDD rules encoded into a rules engine). Federal initiative alignment (CMS ACCESS Model, Medicaid waivers).
Compliance ArchitectureEncryption (TLS 1.3, AES-256), RBAC, audit logging, BAAs, data residency. Built into the stack, not bolted on.
Incident ResponseBlameless RCA with Five Whys, timelines, prevention plans. Story-point-estimated mitigations. Documented, tracked, closed.

Frameworks I Work In

Product Demos & Investor Portals

I lead with demos, not sales docs. Build something the client can react to.

I would rather invest dev resources in a working demo than a polished sales deck. A demo is faster to build, more useful to the client, and gives them something to actually iterate on. Presentations get polite nods. A working demo gets "yes, no, not like that" -- and that's where real requirements come from.

Product Demos

Website Rebuild Demo20+ page production-quality demo for client review2-3 days
Feature DemoSingle feature deep-dive2-4 hrs
Integration DemoAPI integration mockup showing data flow30 min
Why demo-first: A 101-page clickable EHR demo generated more actionable requirements from 8 rounds of async email feedback than months of formal elicitation would have. The demo IS the spec. Every screen encodes a business rule. The client clicks through on their own time and reacts to something real. That's how I sell, and it's how I build.

How I Engage

Pricing model, engagement types, and what to expect
Engagement TypeWhat It CoversPricing
Project-Based Project0-to-1 builds, BA engagements, platform development, migrations, compliance programs. Scoped, estimated, delivered.Story-point priced ($100-200/SP based on engagement)
Advisory AdvisoryCTO-level guidance, architecture review, team coaching, board prep. Monthly retainer with defined scope.Monthly retainer
Rapid Deploy RapidAny rapid-deploy deliverable. One-pagers, proposals, financial models, meeting prep, demos.Story-point priced ($100-200/SP based on engagement)
Why story points? Hours are broken. A task that takes a traditional dev shop 16 hours might take 45 minutes with AI-native orchestration. Story points measure complexity delivered, not time spent. You pay for outcomes. Rate per point scales with engagement complexity ($100-200/SP). That consistency is the point.
