What I'm looking for

I seek roles building scalable mobile and fintech APIs, collaborative teams, opportunities to lead technical projects, and workplaces valuing clean architecture and measurable impact.

I am a results-driven Mobile Application and Full Stack Developer with three years building cross-platform Flutter apps and extensive experience in API design for fintech. I bring strong Java and C# backgrounds, practical Spring Boot knowledge, and experience in Unity and Figma for complementary tasks.

At Smatech Group I led delivery of multiple apps used by over 10,000 combined users, improved performance and maintainability through clean architecture, and built payment and biometric solutions that handled real transactions and scaled to hundreds of users.

Previously I led a team migrating legacy apps to Flutter, engineered secure payment gateways and banking APIs that reduced processing errors, and contributed to increased engagement and sales during an internship, always prioritizing reliable, well-documented solutions.
