About

Backend Engineer with 5+ years of experience designing, developing, and scaling high-performance, cloud-native systems using Java, Spring Boot, and Microservices. I specialize in building reliable, low-latency backend platforms that power large-scale, data-intensive, and event-driven products in regulated financial environments. At Airtel Payments Bank, I lead multiple mission-critical services in the Platform Engineering team, including Aadhaar Authentication, PAN Validation, CKYC, Retry Engine, and Regulatory Auditing systems. I have architected and delivered highly scalable, fault-tolerant backend services used across onboarding, compliance, and billing workflows. Designed a robust auditing framework using Java, Spring Boot, Kafka, Aerospike, and Oracle, enabling real-time regulatory reporting and large-scale data processing with high reliability. Previously at Mercedes-Benz R&D (TEKsystems), I engineered backend systems for the MB.OS platform, improving system throughput by 30% through asynchronous processing, JVM optimization, and event-driven design. Built secure integrations across multiple services using TLS, reduced downtime by 40%, and deployed production workloads on Azure Cloud. Proficient in designing RESTful APIs, integrating distributed microservices, and building fault-tolerant, low-latency architectures. Hands-on with Kafka, RabbitMQ, Docker, JPA/Hibernate, PostgreSQL, MongoDB, Oracle DB, and cloud deployments on AWS and Azure. Experienced in monitoring and observability using ELK, Prometheus, and Grafana for proactive performance tuning and system reliability. Strong advocate of Clean Code, SOLID principles, and scalable system design. Comfortable with concurrency, database optimization, and high-throughput architectures. Active contributor in Agile/Scrum teams, involved in architecture reviews, mentoring engineers, and continuously improving engineering standards. 🚀 Driven by building resilient backend platforms, optimizing system performance, and designing scalable architectures that handle real-world enterprise workloads. 🔷 Open to opportunities in Backend Engineering, Platform Engineering, and Cloud-Native Systems within high-impact, product-focused organizations.
