Full Stack Developer
I build the backend and the web product that uses it
I've spent six years on the server side: the APIs, the real-time streaming and the infrastructure that hold up what I build, with NestJS, Cloudflare Workers and AWS. It's the same work I use to stand up production web and mobile ecosystems, in Angular, React and NativeScript.
The half you can't see by playing
The game decides nothing: every time goes through an authoritative backend on Cloudflare Workers that validates it before publishing it.
- Six endpoints in Hono on Cloudflare Workers
- Idempotency and rate limiting inside a Durable Object
- Both repos open: the API in TypeScript and the client in C#
- 6+Years on the server side
- 4Apps in production for an insurer, across two markets
- 2Public repos: the API and its client
About me
On the server side, and the product that uses it
I've spent six years building what holds a product up: the APIs, the real-time streaming and the infrastructure that keep it standing. Four applications for an insurer over the same services and the same data, replicated in a second market. A platform that brings heavy applications to the browser from AWS, with instances that shut themselves down when no one is using them. And the API that validates every Ghostline run before publishing it. If you'd rather read code than take my word for it, both Ghostline repos are open.

04 — Case studies
Insurtech Ecosystem
Insurance platform · Web, mobile and CRM
Four insurance apps —quoting, CRM, dashboard and mobile— on one shared architecture, replicated across two markets.
Ghostline
Authoritative API on Cloudflare Workers · Durable Objects · live WebSocket leaderboard
An authoritative backend that validates each time with server-side checks, idempotency and rate limiting before publishing it to the leaderboard.
Arvison
Unreal streaming on AWS · NestJS · matchmaker and WebRTC signaling
GPU-intensive Unreal apps running in any browser, with instances that shut themselves down.
RTG Crane Simulator
Pixel Streaming: signaling migrated from Node.js to NestJS · Angular web frontend
I migrated the Pixel Streaming signaling server from Node.js to NestJS and built the web frontend that consumes the stream, from the client's mockup.
Virtual Fashion Runway
Pixel Streaming on AWS · web frontend for the stream
A fashion show in Unreal streamed live to the browser via Pixel Streaming on AWS.
Q-AR
Inventory control · web panel and Firebase
QR-based inventory: registration and reports web panel, Firebase functions, and real-time sync with the scanning app.
The other half
The game systems this backend serves: quests, vehicle mechanics, procedural scenarios and the fail state that forces a fix.
