Full-stack developer: web platforms, scripting & automation, security & licensing

I build full-stack web platforms, game tooling, secure licensing systems and automation, end to end, from the database and account layer up to the UI people actually click.

What I do

Expertise across the full stack

Standalone game resources, hardened licensing servers, automation bots. I design config-first systems that stay framework-agnostic, so they drop into an existing setup without a rewrite.

FiveM resources

Standalone utilities, complex economy systems and instanced multiplayer mechanics. Multi-framework cores with ESX / QBCore / Qbox bridges and config-first compatibility.

Game tooling

Map & zone editors, 2D/3D canvas with Three.js, coordinate systems and spatial geometry. The kind of precision tooling that makes building a world less painful.

Web & mobile

React and TypeScript front-ends, Expo / React Native apps, REST APIs and authentication. Responsive products from a single shared codebase.

Backend, data & cloud

ASP.NET (net8), Flask & Node with PostgreSQL (Neon) / SQLite. Account systems with email verification, password reset and sessions; licensing servers, admin panels, cloud file storage, user-to-user sharing, per-user quotas and in-app update channels.

Desktop apps & automation

Desktop tooling in PySide6 / Qt6 and C# / WinForms, Selenium automation, Telegram notification & reporting bots, and code obfuscation with ConfuserEx.

Security, licensing & infra

RSA-PSS signing, HMAC server auth with replay protection, HWID fingerprinting (WMI), anti-debug, and abuse prevention (rate limiting, anti-enumeration, multi-account dedup). Deployed on Ubuntu VPS (systemd) behind Cloudflare with no exposed origin, encrypted offsite backups and an SSH release pipeline.
