About
I'm a backend-focused engineer with 3+ years of professional experience and a curiosity for technology that started back in 2012 — when I was a teenager building tool websites. That early tinkering taught me something important: building things properly matters more than quick fixes.
I didn't follow a traditional CS path. I did a BA while using that time to pursue technical learning on my own terms. I'm now completing my MCA from IGNOU alongside full-time work — building a B2B WhatsApp SaaS platform as my academic project.
