About

I’m a mobile engineer with 4+ years of experience building and scaling production-grade applications across fintech and consumer platforms. I’ve worked on high-impact payment and lending systems at CRED and Uni Cards, owning architecture decisions, performance optimization, and release stability improvements. Outside of full-time roles, I built and operate a real-time multiplayer card game (Cabo) across Android, iOS, and Web. I designed the hybrid backend architecture, implemented monetization, and manage live production infrastructure and analytics independently. I’m particularly interested in product-focused engineering teams where I can take end-to-end ownership of systems and contribute long-term.
