About
Hey, I'm Mrinal
I am Mrinal Maheshwari, Lead Architect at IndiGo Airlines from India. I design system architecture, set engineering standards, and lead a team of 10 — developers, QA and BAs — from solution design through delivery. Over 6+ years across mobile and web, working in React, React-Native, iOS (Swift) and Android (Java).
I care about systems that hold up under load — cutting API latency from seconds to under 200ms, building reliable payment infrastructure, and closing out security audits — while keeping deliveries on schedule.
