Turning ideas into
robust web systems

I'm a results-driven Full-Stack Web Developer with 3+ years of experience crafting SaaS web applications that are clean, scalable, and performant. My toolkit centers on PHP (CodeIgniter) and Python (Django), backed by solid JavaScript and MySQL fundamentals.

I've contributed across diverse domains — EdTech, healthcare, social platforms, and national research infrastructure — delivering features that real users depend on every day. I'm equally comfortable designing database schemas, consuming third-party APIs, or mentoring junior developers through code reviews.

Currently at ZDotApps Technologies, I'm leading a PHP 5.6 → 8.1 migration, building gaming products, and maintaining multi-tenant SaaS APIs. Previously, I built the I-STEM platform at IISc — a national facility that connects researchers with scientific equipment across India.
