What I'm looking for

I'm looking to lead mobile platform architecture and engineering initiatives where scalable SDKs, modular systems, reliable delivery, and long-term technical foundations drive business growth.

At Coffeebeans Consulting, I architect native mobile platforms for high-scale finance and retail products, including a UPI super app serving tens of millions of users.

I redesigned a Merchant UPI Payment SDK into a SOLID-compliant, layered framework with dependency injection, supporting 99.9% payment reliability. I also built a modular iOS platform across eight business modules and capability SDKs for authentication, security, networking, and analytics.

Previously at Persistent Systems, I led iOS and Android teams, built healthcare telemetry and security integrations, and delivered modular navigation and mobile R&D frameworks. I focus on clean architecture, reliable releases, and platform foundations that help teams ship faster.
