Projects
Venture-Backed Travel SaaS (USA) | Lead Web Engineer
// problem
A venture-backed travel SaaS platform suffered a critical security event, exposing vulnerabilities across its legacy AWS infrastructure.
// approach
Led a forensic audit, remediated the AWS Lambda/Cognito vulnerabilities, migrated to Node 20, and stood up automated CI/CD pipelines.
// result
Restored the platform to 99.9% production uptime with a secure, stable foundation for rapid feature iteration.

- Node.js
- AWS Lambda
- AWS Cognito
- TypeScript
- GitHub Actions
Enterprise Event Registration Platform | Systems Architect
// problem
The client needed to check in 400+ attendees across a two-day event — offline-reliable, zero downtime, with staff able to fix issues on the fly.
// approach
Built an installable desktop app switching between offline (SQLite) and online (Supabase) modes, with QR scanning, instant PDF badge printing, and an admin console for per-event configuration and a drag-and-drop badge editor.
// result
Ran registration for 400+ attendees across both event days with zero downtime and a self-serve admin console for staff.

Interactive UV Print Experience Platform | Full-Stack Developer
// problem
The client's original UV printing workflow required many repeated manual actions from the admin/operator, preventing it from scaling to support custom designs for event attendees.
// approach
Built a cloud-hosted kiosk web app with a touch-friendly design editor and a scan-to-upload mobile bridge, plus a background sync agent that auto-feeds finished designs into the UV printer's RIP software.
// result
A hardware-agnostic, multi-event platform running the same design experience across concurrent events on any tablet, with no manual file handling.

Birding Data Platform | Mobile & Web Systems Architect
// problem
The client had built up their own collection of bird species data with no way to browse it on the go, and no easy way to keep it updated.
// approach
Started with an offline-first React Native app to bring the collection to mobile, then a Next.js/Supabase web platform for uploading and editing species data (media compression, self-healing CSV import), and finally a sightings engine — lazy-auth to keep browsing public, Row Level Security for private data, and sighting-first storage so one sighting can belong to multiple lists without duplication.
// result
A full-stack platform spanning mobile, web, and cloud — with no-code data management and privacy-protected personal sightings at low storage cost.

- Next.js
- WatermelonDB
- SQLite
- Supabase (Auth/Storage/RLS)

AI Generation Platform | Prompt Architecture Consultant
// problem
An LLM-driven generation platform had unpredictable model behavior and inconsistent structured outputs.
// approach
Audited the existing architecture, then engineered V2 prompt reasoning chains and structured output schemas to constrain model behavior.
// result
Achieved 95%+ consistency in structured JSON outputs with minimal hallucinations.
