Hello, I'm
Anastasis Giakoumatos
Senior Mobile Engineer · Android
Android apps used by millions, shipped faster with AI
I'm a Mobile Engineer specializing in Android, based in Athens. For 7 years I've built apps people trust with their money: banking, payments and iGaming apps used by millions. Today AI is part of how I ship: coding agents help me move faster, automation takes repetitive work off the team, and AI features go in where they make an app genuinely better. What hasn't changed is the bar. Clean architecture, tests and code reviews keep speed from ever costing stability.

7 years shipping Android apps in banking, payments and iGaming.
Senior Android Developer
Cognity (B2B Contract)
I'm part of the 35–40 person Android team behind Eurobank's mobile banking app. I led a large modularization effort, moving 1,500+ files into 10+ new modules, and brought unit tests to modules that had none, so the team can ship changes with more confidence.
Senior Android Developer
BetssonGroup
I helped move the Sportsbook from WebView screens to native Android with Jetpack Compose and MVI. I kept the QA rejection rate under 3%, held the app at 96% crash-free sessions and reviewed 50+ pull requests a quarter. This is also where AI tools became part of my daily workflow (Cursor, Copilot, Claude, Gemini), helping me ship features faster without lowering quality.
Android Engineer
Viva.com
I worked on the Viva.com Terminal app, used by 1M+ people in 10+ European countries. I added tablet and landscape support across 35+ screens, which let the app run on new devices like cash machines and vending machines. I also built its Kiosk mode and led the app rebranding.
Android Engineer
M-Stat
Where I grew into a tech lead. I built and maintained 15+ Android apps for insurance and loyalty clients, often as the sole Android developer, including the award-winning KRAFT Pro App (Impact BITE Awards 2021) and Piraeus Bank's Yellow, a top banking app in Greece five years in a row. As tech lead I owned estimations, worked directly with clients and mentored junior developers.
