About
Engineer who thinks
like a founder.
I'm a Software Development Engineer at Transformatrix Global, where I build full-stack web and mobile applications.
I focus on building scalable, high-quality products with a strong emphasis on business outcomes. From concept to deployment, I approach every project with user-centric design and data-driven decision making — ensuring what I build actually moves the needle.
I leverage AI tools and modern frameworks to ship faster without compromising quality. Whether it's a client-facing app, an internal tool, or an automation pipeline — I build things that work and scale.
I also build my own products and experiments at Gaven's Studio — and love collaborating with anyone who has an idea worth building: studio.gaven.in

Nari Kavach AI
Walking routes that weigh recent community reports for the time you walk.
Navigation apps answer “what's the fastest way?” For a woman walking home from the station at 9:30 PM, that isn't the only question. Nari Kavach reads anonymous community reports hexagon by hexagon, the way Uber reads cities with H3, and compares routes with them.
- Compares walking routes and says why: "About 4 min longer and avoids areas with elevated recent reports around this time."
- Anonymous reports in a few taps. A local AI pre-fills follow-up answers; rules, not the AI, make every decision.
- Community map: an area lights up only when 2+ people reported, shown as ranges.
- SOS: 112, the 181 women helpline, nearest police and hospital.
How I built it
I designed the architecture: a modular monolith, PostGIS for map queries, H3 hexagons for area signals, self-hosted routing, and a local AI that can only suggest. Privacy rules from day one: start and end points are never stored. Claude Code was my AI pair programmer; the judgement calls, reviews and on-device testing stayed mine. 550+ automated tests.
