As you already know, My name is Chizaram Onuorah - but you can call me Maraz
I'm a mobile developer with a passion for transforming ideas into fast, elegant, and reliable apps that users genuinely enjoy. With over 3 years of hands-on experience in Flutter and native integrations (Android & iOS), I've built and shipped more than 15 cross-platform applications across domains like fintech, IoT, real-time systems, and more.
I prioritize clean architecture, maintainable code, and performance optimization — because the best apps don't just function; they deliver seamless, intuitive experiences. From tackling advanced state management and native module integrations to refining pixel-perfect UI animations, I thrive on solving challenging problems that elevate app quality.
When I'm not deep in code, I recharge by diving into things I'm truly passionate about:
- Catching up on great series — whether it's rewatching classics or discovering new ones
- Supporting my favorite team, Liverpool FC — watching live matches, highlights, or diving into football and basketball games
- Playing the bass guitar, exploring instrumentals, or enjoying creative song covers on YouTube
- Getting out on the pitch myself for a game of football with friends.
- Music in general — it's my biggest non-tech passion, from listening and analyzing tracks to appreciating different genres and artists.
I also enjoy staying curious about the world of tech, writing about mobile engineering insights on Medium, and occasionally experimenting with new ideas or tools that push my skills forward.
I'm always open to collaborating on impactful projects, exchanging knowledge with fellow developers, and building solutions that make a real difference. Feel free to reach out — let's connect!
Tools, tech, and techniques I use to bring ideas to life — cleanly, efficiently, and at scale. I am always looking to add more skills.
