Full-Stack Engineer (Solo Build) at Quadrant

August 1, 2026 - Present

Solo-built and launched Quadrant, an encrypted weekly planning app in closed beta. Shipped end-to-end features across Next.js 16/React 19, TypeScript, Prisma 7, and PostgreSQL with mobile PWA support, desktop layouts, notifications, and a beta feedback pipeline. Implemented zero-knowledge browser encryption (Argon2id + XSalsa20-Poly1305), rate-limited auth with anti-account-enumeration, and signed recovery tokens. Fixed production-grade issues including timezone-related week boundary bugs and layout redirect loops. Enforced rules at the database level with unique constraints, triggers, and advisory locks. Built an MCP server for AI agent workflows to seed data, run Playwright E2E tests, simulate scheduled jobs, and inspect database metrics; added regression checks that gate PRs.

Full-Stack Engineer (Solo Builder) at Quadrant

August 1, 2026 - Present

Solo-built Quadrant, an encrypted weekly planning app in closed beta. Shipped 25 API routes, 11 data models, 8 migrations, and a mobile PWA with notifications. Implemented zero-knowledge client-side encryption using libsodium (Argon2id + XSalsa20-Poly1305), added rate-limited and anti-account-enumeration auth routes, and used signed short-lived recovery tokens. Debugged redirect loop/root-cause issues tied to timezone week boundaries (UTC+7) and layout routing, then enforced rules with database constraints, unique indexes, and Postgres triggers using advisory locks for concurrency safety. Built an MCP server so an AI agent can seed scenarios, run the Playwright E2E suite, simulate cron jobs, and inspect database metrics; added PR-gating regression scripts that fail on critical week/timezone regressions. Included human sign-off requirements for closed fixes and planned consent-based MCP access for personal AI assistant workflows.
