Mike Chionidis

👋 Hey, I'm Mike! I'm passionate about building data-driven products and integrating AI into real-world applications. My philosophy is simple: Move Fast, Ship Often, Iterate Constantly. From Fortune 500 companies to innovative startups, I transform ideas into functional products with speed and precision.

My Story

My journey began with a simple question: "How can we use data to make better decisions?" This curiosity led me down a path that would transform my career and impact Fortune 500 companies along the way.

Armed with a Master's in Electrical and Computer Engineering, I dove into the world of data and AI. What started as an internship building APIs quickly evolved into something much bigger. Within just two years at Margera, I went from Junior Engineer to leading a team of engineers, proving that passion and determination can accelerate growth beyond traditional timelines.

The highlight? Delivering five MVPs in two years that revolutionized how brands like Samsung, Three Mobile, and Western Union leverage their data. Two of these solutions even received industry awards for innovation in AdTech—a testament to what's possible when technical expertise meets creative problem-solving.

Today, I channel this experience into two ventures: my freelance practice, where I build end-to-end AI and data products, and DataProjects.io, a platform I founded to help aspiring data professionals develop real-world skills through hands-on projects.

My approach is straightforward: understand the problem deeply, move fast, ship often, and iterate constantly. This philosophy has guided me through complex challenges across the full technology stack—from React and Next.js frontends to Python backends, cloud infrastructure, and sophisticated AI integrations.
