I build high-performance, resilient backend systems and production-grade infrastructure. Specializing in Go, Node.js, Linux, Docker, and scalable API design — turning complexity into systems that just work.
A full-spectrum toolkit spanning backend runtimes, systems administration, and infrastructure automation.
Engineering case studies — from game server infrastructure to fintech backends.
Containerized a legacy monolithic Win32 game server into an isolated Linux Docker bridge network with dedicated TCP socket proxying, SYN flood mitigation, and automated restart watchdogs. Achieved near-zero configuration drift.
Modular web PDF editor engineered in React and TypeScript using pnpm workspaces. Integrates Mozilla pdf.js for page rendering, pdf-lib for binary document manipulation, and HTML5 Canvas for interactive vector annotations, signatures, and drawing.
Expense validation and calculation engine built with precise decimal arithmetic, automated input sanitization, dynamic item aggregation, and responsive client-side state management for accuracy-critical financial flows.
Client appointment scheduling application for service businesses. Features dynamic slot availability logic using Day.js, reactive form validation, mock REST API persistence via JSON-Server, and a custom Webpack 5 development and build pipeline.
High-concurrency multiplayer dedicated game server utilizing C++ core runtime and event-driven Lua engine. Engineered real-time player synchronization, low-latency UDP/TCP packet handling, security sandboxing, and MySQL database integration.
Production-grade Webpack 5 and Babel compilation configuration featuring modern JavaScript transpilation, tree-shaking, CSS loaders, asset optimization, and multi-environment build profiles for high-performance delivery.
Key engineering milestones, open-source technical systems, and real-world architectures built across modern software stacks.
Engineering OpenPDFEdit — a modular, zero-server web PDF manipulation suite built with React, TypeScript, and Vite.
Modernized and containerized multiplayer game server environments (Mu-server & MTA-SA) for Linux hosts.
Engineered responsive client applications and production build pipelines (HairDay, Refund, and Bundlers).
