“The single best agentic SDLC framework I've ever seen.” — Head of AI

A language-agnostic, multi-agent framework that drives the whole delivery lifecycle — PRD → tasks → implementation → test → review — through a fleet of orchestrated Claude subagents, with swappable per-language packs and pluggable context sources. Grew from a personal experiment into tooling adopted across the org.

Card-testing countermeasures

Principal countermeasure developer on a donor-payment platform processing tens of millions monthly. Programmatic detection cut successful card-testing from yearly spikes of ~100k to typically under a few hundred a month.

Customer identity service

Modeled and built a service that reconciles customer records scattered across acquisition-era monoliths into single billable entities — chapters, fiscal-sponsor relationships, intentional and accidental EIN overlaps. Backed by a multi-key cache.

Monolith → services

Refactored CRM provisioning into tight, Clean-Architecture units, then drove extraction of billing and provisioning logic out of the monolith into cross-monolith microservices — co-designing the services that replace it.

Internal command center

A service that wraps commands across the company's portfolio of applications, giving admins, superusers, and support one control surface over otherwise disconnected systems.

ocelot — live

flutter · offline-first

A fitness performance partner that never needs a signal.

Cross-platform on a single Flutter/Dart codebase — web, iOS, Android — with a daringly customizable workout-routine generator and social features. The interesting part is underneath.

  • Offline-first by design. Reads and writes land in a local SQLite store (Drift); the app is fully usable with no connection.
  • Last-write-wins sync on persisted modification timestamps reconciles divergent local and remote state on reconnect.
  • Anonymous logins — a personalized experience that collects no identifying data. A principled stance, not an afterthought.

What I'm after

I want to build things that are genuinely interesting and worth being proud of.

Most of my best work has the same shape: take something fragmented — records across a dozen monoliths, a payment platform under constant fraud, a delivery process that sprawls across a team — and resolve it into something coherent. I like the hard, unglamorous middle of that: the data model, the cache, the refactor that makes the next ten features cheap.

I care that the work is economically just and actually useful — creating value, not recycling capital on a hamster wheel. Direct, a little lateral, and easy to work with. If you're building something real, let's talk.
