As an Engineering Manager at Fynd, I lead a 19‑engineer agile team to build cart and payment services for high‑scale e‑commerce apps, architecting a payment extension ecosystem and microservices that boosted conversion rates by 70%. I spearheaded Gauze.Health’s GDPR‑compliant healthcare platform, FHIR API and DICOM workspace, and led ML‑driven ECG and echo analysis. I mentored and grew talent, driving 70% productivity gains.

Led a team of five engineers to build cart and payment services with payment prioritization, customizable COD, targeted promotions, and payment links. Architected fault‑tolerant, event‑driven microservices with circuit breakers, idempotency retries, auto‑scaling, and multi‑AZ design to maintain 99.95% uptime. Added OpenAPI Swagger for SDK generation (−80% integration time), integrated SonarQube/Snyk (−95% vulnerabilities), and built an audit trail boosting fraud detection by 99%.

Designed a payment‑as‑a‑service integrating multiple gateways, boosting transaction efficiency by 95%. Decoupled a monolith into microservices using strangler and event‑sourcing to handle 1M+ RPM at 75 ms latency. Fixed 25+ bugs and added OMS features. Optimized performance via caching, query tuning, async design, and load testing for 99% gains. Achieved 85%+ test coverage and 90% fewer bugs. Enhanced monitoring with Sentry, Prometheus, NewRelic, and Elasticsearch.

Led backend development of a travel booking platform with search, booking, checkout, recommendations, and authentication. Built an admin dashboard for trip management, coupons, analytics, and chatbot setup, reducing management time by 80%. Developed a Facebook chatbot with DialogFlow to automate inquiries. Improved page load by 90% (−150 ms) via caching, DB tuning, CDN, async tasks, and scaling. Integrated APIs with Django and services like Mailchimp, Exotel, FreshSales, and Razorpay.

Designed and developed key game features—bot/table assignment, player limits, and boot amounts—to enhance gameplay; troubleshot and resolved RealTeenPatti issues; configured Nagios to monitor application, Redis, and MySQL resources; built an analytics dashboard for DAU, bot, and player metrics; automated daily report emails using Mapplot and SMTP; and leveraged Golang, Python, and Django for scalable web apps.

Implemented courier pin‑code mapping and signed‑manifest uploads to enhance user experience and streamline operations. Optimized complex SQL queries and application code, significantly improving order and return panel performance. Managed bug fixes and feature enhancements to boost stability and functionality. Employed PHP, MySQL, SVN, and JavaScript to refine web applications, elevating code quality and overall performance.
