About Me

I started my professional journey in Civil Engineering, which built my foundation in analytical thinking and rapid problem-solving.

Transitioning into software engineering taught me to be a 'polyglot' developer—focusing on architectural patterns that apply across any language or framework.

With 5+ years of experience, I specialize in bridging the gap between mobile frontends and complex backends, delivering production apps used across multiple countries.

I thrive on technical variety: architecting clean mobile apps in Flutter, building enterprise service layers in Spring Boot and .NET, and deploying agile, cloud-native logic with JavaScript.

I am heavily focused on Generative AI, using tools like Spring AI to build intelligent, data-driven features into the product core while leveraging AI to accelerate my own engineering lifecycle.

Having served as a Tech Lead, I am an ownership-driven teammate who manages feature delivery end-to-end. I am highly adaptable and open to relocation for the right opportunity.

Career Journey

5+ years of building across mobile, backend, and full-stack — from freelance roots to production systems at scale.
