Door Ventures · April 2023 — present
Due-diligence questionnaire management for asset managers and fund investors. Both sides of the transaction work in the same platform: one side sends the questionnaires, the other answers them, and every answer carries its own provenance and review state.
I am the top committer across the platform — the front end, the API, the design system and the previous UI — and second on the database. Around 3,100 commits, merge commits excluded.
React 19 on Next.js 15 in TypeScript. I rebuilt the review page — the busiest screen in the product — on a streamed questionnaire, with optimistic saving, answer provenance and compare-to-previous.
I own the design system, the colour and status vocabulary, the interaction patterns and the WCAG 2.1 AA standard we hold the product to. It usually starts with working out what we are actually trying to solve.
FastAPI and SQLAlchemy over PostgreSQL. Endpoints, schema, migrations, and the query work behind them — including moving admin lists to page, sort and export server-side rather than in the browser.
Lambda services and Step Functions — SES event ingest and bounce handling, notification dispatch and digest jobs, the document parser, and the state machines behind request processing and offline completion.
I wrote our original Cypress suite, then rewrote end-to-end testing onto Playwright for the new platform: 746 tests, none failing and none skipped, with fixture ownership, parallel safety and reliable runs against deployed environments.
Server-side paging and export, lazy pickers, and a query cache keyed by user rather than bearer token. Role-based access control, with internal roles visible to admins and editable only by Super Admin.
I led AI into the platform, automating report generation from client questionnaires and bridging OpenAI and AWS Bedrock. I also keep the conventions that stop generated code drifting from the rest of the codebase.
I still maintain classic Door, the original Java and Gradle platform that predates all of this, and I mentor the junior engineers on the team across both the front end and the back end.
git shortlog across eight repositories, merge commits excluded. Rank is my position among all contributors to that repository.
The platform itself sits behind a login. The company’s marketing site does not — I rewrote it from the ground up, and every commit in that repository is mine.
