I build software systems that solve practical problems from backend APIs and web platforms to computer vision, automation, networking tools, offline-first applications, and hardware-connected systems.

My work spans software engineering, product development, AI integration, and technical prototyping, with a strong focus on building reliable systems that can operate in real-world environments.

I design and build scalable applications, APIs, data platforms, dashboards, and business systems.

Technologies:
Node.js Express Laravel FastAPI Go React Next.js TypeScript PostgreSQL MySQL MongoDB SQLite Redis

I enjoy working beyond conventional web applications, including local-network software, desktop services, mobile applications, offline-first systems, and distributed application workflows.

Technologies:
C++ Flutter C# Docker Linux REST APIs WebSockets Networking PWA

I build practical AI-enabled systems for image processing, prediction, automation, and intelligent decision support.

Technologies:
