Web & Automation Developer · East Falmouth, MA · Remote (US Eastern)
Self-taught developer. I ran the entire technology operation for a solar company solo for nine years, and now build production web, automation, and AI systems independently.
I work AI-assisted and treat it as an engineering practice rather than a shortcut: changes go through a documented cross-model review gate before they ship, and I can explain and defend the decisions in the diff. Comfortable being the only technical person in the room, and explaining it to people who are not.
Available for remote full-time, contract, or part-time work.
Data-intelligence platform for a private investment firm (contract, under NDA) Took over a demo-stage build and grew it to a production maritime-intelligence platform in about six weeks: Next.js 15 PWA and FastAPI, PostgreSQL/TimescaleDB, Redis, 100+ live data sources. Split it into two independently deployed products under a hard deadline, and closed the engagement with a 336-line engineering handoff and a staffing recommendation for the client's incoming team.
Security knowledge graph, 1.7M+ records Hybrid graph and full-text search over 90+ public security datasets: a 1.77M-node Memgraph graph, a 3.1GB SQLite FTS5 mirror, and a local-first Python query CLI, fed by a custom ingestion, dedup, and export pipeline. Integrated into an AI-agent workflow.
LLM training dataset and pipeline A 442K-example instruction-tuning dataset built with an ~8,700-line Python synthetic-data pipeline (scenario generation, quality filtering, validation), plus a two-stage LoRA fine-tuning setup designed for a 32B code model.
Production SaaS platform, built solo (voice/audio, now being retired) A complete subscription SaaS on my own: FastAPI and Next.js, PostgreSQL with Alembic migrations, Redis, Stripe billing, JWT auth, GPU inference, deployed on Linux under systemd. Roughly 11,600 automated tests across 1,181 test files, with the load-bearing architecture choices written up as ADRs rather than left implicit. Retiring it in 2026 because the hosting and GPU economics did not justify continuing, and I would rather close it cleanly than keep paying for it.
Ranked a solar company #1 and built its intake system Built and ran the company WordPress site to #1 Google rankings for its core Martha's Vineyard solar searches, and coded its lead-capture and onboarding system solo (React/TypeScript, Node, PostgreSQL) with address autocomplete, satellite property confirmation, service-area validation, automated customer email, and two-way CRM sync, containerized and self-hosted.
