I’m Prince E. Nyamadi, a results-driven Software Engineer with 7+ years of experience crafting innovative, scalable, and impactful digital solutions. My work spans mobile, web, and backend systems, with a deep passion for building seamless user experiences and robust architectures.
I specialize in cross-platform development with Flutter, responsive frontend engineering using Angular and React, and API-first backend systems built with Spring Boot and Node.js. My approach blends clean code practices, product thinking, and a strong focus on performance and maintainability.
Throughout my career, I’ve led and contributed to projects across fintech, travel, and IoT automation, taking ideas from concept to production with a blend of technical execution and collaboration.
Whether I'm shipping mobile apps, building web platforms, or deploying serverless APIs, I’m driven by curiosity, committed to continuous learning, and inspired by real-world problem-solving.
