PB
Product builds, zero to launch
Took an outbound campaigns platform from zero to launch — schema, queue workers, AI and the full React UI — as one of three engineers. You get one person who owns the product end to end.
Services
Each one comes with the proof of why you'd choose me for it.
AI
AI and LLM features that hold up
Found and fixed a Gemini parsing defect that was silently failing every scoring call, then added defensive parsing, token limits and logging at every model boundary.
IN
Integrations and automation
Eight third-party platforms integrated in one engagement with retry, backoff and idempotent webhooks — and Twilio call-centre integrations since 2017.
CL
Cloud and serverless — and cutting its cost
Cut infrastructure costs 35% with a serverless migration and 40% with a move to AWS. This site runs for under a dollar a month.
DB
Data pipelines and ETL speed-ups
Claims processing from 30 days to 20 minutes; a billing cycle from 24 hours to under one, at 100,000+ records a day.
ID
Secure identity and smart cards
Built an ICAO 9303 ePassport and smart-card platform solo — custom Java Card applet, GlobalPlatform loader, Passive Authentication. A rare skill set.
AP
Desktop and mobile apps
Windows (.NET 8 / WPF), Android (Kotlin, Compose) and React Native — shipped as portable single-file builds where the job needs it.
TL
Technical leadership
Former CTO; led a team of seven; Scrum, CI/CD and test discipline (95% coverage). Lead, embed with your team, or fractional.
AD
AI-assisted development for teams
Builds custom agents and tooling that encode a codebase's hard-won knowledge, so any engineer can work safely in unfamiliar code.
