About
Building durable systems and fostering a culture of ownership.
Strategy & Leadership
Translating business OKRs into engineering roadmaps. Managing squads, designing org structures, and growing engineers into senior practitioners.
Architecture & Scale
Designing high-throughput distributed systems — Java, Python, Node.js — in FinTech and HealthTech with strict SLA governance and observability.
Full-Stack & AI
Deep across the stack: backend APIs, React/React Native frontends, and integrating modern AI — LLMs, Gemini API, agentic workflows — into production systems.
Currently leading engineering at Onsurity — managing three cross-functional squads (18+ engineers) across mission-critical HealthTech, Wellness, and Payment/Billing systems. Previously at BharatPe, I led backend and mobile engineering, aligning engineering objectives with product leadership to convert business OKRs into strategic technical roadmaps.
I specialize in defining technical roadmaps and Engineering Excellence frameworks. I've introduced rigorous Design Docs & Code Reviews, elevated multiple engineers to senior roles, and reduced production anomalies by 80%. By integrating cloud-native orchestration and AI-driven workflows, I've driven a 4x acceleration in software development velocity and cut onboarding time by 40%. Passionate about engineering culture, operational excellence, and building teams that outlast the sprint.
