Where I've
been building

Jun 2026 – now
New Delhi

Freelance Developer · Limitless Koffee

Developed the loyalty rewards app for Limitless Koffee, a budding café chain in New Delhi, end-to-end and independently under a tight launch timeline, on Next.js and Supabase with WhatsApp OTP login via the Meta WhatsApp Business API. Built an analytics dashboard to track usage and bulk-send WhatsApp reminders to customers who hadn't redeemed their signup offer. Re-implemented the app on a tRPC architecture in place of plain HTTP and optimized database round-trip times to hit a strong speed score, while exploring frameworks like SolidStart along the way.
