About

Senior Technical Lead I’m a Backend Developer with a strong foundation in Java, Spring Boot, and modern backend ecosystems like Kafka, Redis, MongoDB, MySQL, and Kibana. Currently working on the EMI module at Paytm, where I build scalable microservices for managing loan workflows and real-time financial transactions. I began my journey as a White Box QA / Sr SDET Lead, where I honed deep skills in automation, API testing, and performance engineering. That foundation now strengthens my approach to development — enabling me to create systems that are not only scalable and performant, but also testable and robust. In my current role: I specialize in building distributed backend systems and automation platforms powered by AI. • Designed high-throughput Kafka consumers for real-time event processing and database streaming. • Built scalable REST services using Spring Boot with Redis, MongoDB, and Kibana for end-to-end observability. • Developed high-performance service simulators handling 300+ TPS to stress-test internal systems and ensure production-grade reliability. I’m equally passionate about applying AI to improve engineering efficiency. I’ve built AI-powered internal developer tools using CodeBERT, Gemini, CodeLlama and Hugging Face that: • Analyze code and PR diffs for automated validation insights • Identify failure patterns from logs and test results • Predict flaky or risky components and trigger smart alerts

Promoted

Apr 2023 – Present · 3 yrs 1 mo

1. Working on the EMI Affordability module in a Payment Gateway platform — designing and developing backend services for dynamic EMI transactions, eligibility flows, partner integrations, and scalable orchestration.
2. Built high-performance REST APIs using Spring Boot for internal simulation services, enabling large-scale transaction testing and load scenarios for performance benchmarking.
3. Developed Kafka-based consumer services to process real-time events and automation triggers with retry mechanisms, dead-letter handling, and full observability (metrics & structured logging).
4. Contributed to the MARS (Monitoring Alerting Recovery System) platform as a backend engineer — implemented core microservices for system health monitoring, automated recovery workflows, and distributed alert processing.
5. Collaborated with Product and Engineering teams to design solution architecture, translate requirements into modular backend components, and deliver robust production-grade services.
6. Ensured backend systems are easily testable and maintainable — participated in architecture reviews, design discussions, and supported engineering quality through API design guidelines & validation frameworks.
7. Performed in-depth debugging and log-driven analysis for production systems — resolved critical issues, tuned performance bottlenecks, and improved reliability across services.
8. Optimized backend performance across messaging systems, microservice communication, and failure-recovery workflows — focused on fault tolerance, latency reduction, and throughput improvements.
