About

Mid-level engineering, product mindset.

I started Flutter during university and quickly became one of the strongest mobile devs in my circle. Today I architect production-grade apps used by real users — focusing on performance, scalability and beautiful UX.

My Story

I fell in love with mobile engineering during my CS degree. While classmates were still building tutorials, I was shipping real apps — solving messy problems like offline sync, real-time chat, and complex multi-role systems.

Today I work as a Flutter Developer at evyx, owning features end-to-end on large-scale products. I obsess over architecture decisions, performance budgets, and the small UX details that make apps feel premium.

Beyond client work, I run HappyTech — a YouTube channel teaching modern Flutter to a growing community of developers.

Engineering Mindset

Clean architecture, SOLID, scalable state management with Bloc/Cubit.

Product Thinking

I ship features that move metrics — not just code that compiles.

Real-World Experience

Production multi-vendor apps, real-time chat, payments & AI.

Knowledge Sharing

Educating thousands of devs through HappyTech on YouTube.

Experience

A timeline of real impact.

From a curious student to shipping production apps — here's the path.
