Trafalgar TicketsCurrent

SaaS for a Video Game

Founder and Sole Engineer

Designed, built and operate a multi-tenant SaaS platform for online gaming communities as the sole engineer, spanning around 70 pages and more than 120 API endpoints, delivered in more than 12,000 commits.

  • Architected the data layer end to end: more than 200 PostgreSQL tables governed by over 550 row-level security policies and 300+ stored functions, so authorization is enforced inside the database rather than trusted to application code.
  • Built a distributed compute pipeline across two cloud providers that queues, schedules and meters CPU-bound jobs, with per-job machine reservation, three independent orphan guards and per-chunk cost telemetry reconciled against the provider invoice.
  • Engineered a realtime collaborative planning editor with live cursors, shared annotation and layout-independent coordinate anchoring, so collaborators at different zoom levels, scroll positions and filter states always see each other in the right place.
  • Delivered the full commercial surface alone: subscription billing with idempotent webhook processing, OAuth across five providers, a signature-verified Discord bot, and a public REST API secured by two classes of encrypted key.
  • Held quality at that scale with more than 1,100 test files covering over 9,700 cases, a golden-file corpus pinning four independent export formats, and 230+ internal engineering documents.
  • Technologies used: TypeScript, React, Next.js, Node.js, PostgreSQL, Supabase, Redis, Stripe, Tailwind, Vitest, Docker, Google Cloud, Oracle Cloud, Vercel
