01. ABOUT_ME

As a platform architect with over a decade of leadership experience in software technology, I view coding as a medium for creativity—a way to build innovative solutions and drive impact. My passion for startups and emerging technologies keeps me at the forefront of the latest tech stacks, pushing my curiosity and fueling my thirst for continuous learning.

I have a proven track record of designing and building platforms/products from scratch, scaling them to serve millions of users. My expertise spans a broad spectrum—from mobile app development to data engineering, analytics, and Gen AI. As a full-stack developer, I thrive on building scalable and reliable systems while constantly exploring new ways to push the envelope and innovate.
