Nicolas Nazarko

🎯 Experienced Embedded Software Developer delivering reliable, secure, and scalable firmware for IoT and smart devices. With over 10 years of hands-on experience, I’ve built embedded systems deployed in commercial products across international markets, including Europe.

I specialize in low-level programming, real-time architectures, and secure communication protocols across diverse hardware platforms. Passionate about building embedded systems from scratch -integrating low-level drivers, designing scalable architectures, and crafting intuitive device logic with user interaction in mind. I enjoy working across the entire stack, ensuring that each layer - from hardware abstraction to application behavior - is thoughtfully designed, efficient, and reliable, even in resource-constrained environments.

Strong communicator with experience leading small development teams and collaborating with clients, committed to supporting products through their full lifecycle - from development to long-term maintenance and improvement.

🤝 I’m ready to help bring your idea to life. Feel free to reach out anytime.
