Independent · React, TypeScript, NestJS, PostgreSQL, PGlite, Playwright

• Built an evidence-first workflow that preserves exact source context, versions business rules, and connects requirements to APIs, tests, screens and related work.
• Kept impact decisions explicitly human-reviewed, with optional AI suggestions bounded by schema validation and exact evidence quotation.
• Implemented the React and TypeScript interface, NestJS API, PostgreSQL and embedded PGlite data paths, Playwright coverage, and a Vercel-hosted fictional resettable demo.

Independent · TypeScript, Next.js, Node.js, SQLite, WSO2 API Manager

• Built three real HTTP sandboxes to reproduce lost responses, duplicate events, rate limits and unexpected response schemas.
• Routed delivery requests through WSO2 API Manager 4.7.0 using server-side OAuth; deployed the frontend on Vercel and the backend on DigitalOcean.
• Used idempotency keys and ledger reconciliation: the controlled timeout experiment committed one delivery with recovery, versus two in the baseline.
• Added HTTP and browser tests, execution timelines, saved history, and downloadable PDF/JSON reports with architecture and deployment documentation.
