SAGAR
Building futuristic apps & secure digital experiences. 3.4+ years of shipping production-grade code.
WHO AM I
Professional Story
I'm Sagar — a developer who lives at the intersection of beautiful UX and bulletproof security. With 3.4+ years building production apps, I've architected CRM systems, real-time communication platforms, and cross-platform mobile experiences.
My hacker mindset means I don't just build features — I stress-test them, audit their security posture, and ship systems designed to withstand adversarial conditions.
