Engineering the Future,
One Commit at a Time

I'm a Full Stack Software Developer with over 8 years of coding experience and a strong academic foundation — graduating with an MSc in Data Science with Distinction from the University of South Wales, UK.

My journey spans from crafting fintech mobile wallets and humanoid robot AI systems to building educational platforms and modern web applications. I bring expertise across the full stack — from Android & Java backend engineering to Node.js APIs, Vue.js frontends, and cloud infrastructure.

I thrive at the intersection of software engineering and data science, leveraging AI tools to accelerate development. Whether it's architecting a secure REST API, optimizing Docker deployments, or building an educational game — I approach every challenge with curiosity, precision, and creativity.
