I'm a developer who builds production-ready systems across the full stack. From enterprise authentication services to AI-powered search platforms, I focus on creating robust, scalable applications.
-
Full Stack Development: I build complete applications using Next.js 15, React 19, Spring Boot, FastAPI, and Node.js. My projects range from real-time chat platforms to e-commerce systems with AI-powered search.
-
AI & ML Engineering: I implement RAG pipelines with LangChain and ChromaDB, build multi-provider AI chat systems using Vercel AI SDK, and develop ML models for real-world problems like air quality impact analysis and facial recognition.
-
IoT & Embedded Systems: I've built a complete E-Paper Dashboard system that turns jailbroken Kindles into smart displays, TOTP-based Smart Locks with companion Android apps, and CCTV automation with motion detection and Telegram alerts.
