I enjoy turning business requirements into scalable, secure, and user-friendly products. My experience includes mobile architecture, RESTful and event-driven APIs, BLE device integration, eSIM provisioning, real-time communication, payments, cloud services, CI/CD, and technical leadership. I also use AI-assisted development tools such as Cursor, Claude Code, GitHub Copilot, ChatGPT, and Gemini to improve productivity and code quality.
