About

• Worked as a Backend Engineer in the Payments Team, playing a key role in developing and maintaining critical infrastructure for payment processing. Focused on building scalable, reliable, and low-latency services to ensure seamless transactions for users. • Improved payment gateway performance by 10% by introducing intelligent caching strategies and leveraging Kafka Streams for real-time processing, significantly reducing the load on downstream systems and enhancing the user experience during peak traffic. • Designed and implemented an event-driven publish-subscribe architecture to power the team’s notification system. This decoupled architecture allowed for scalable delivery of real-time alerts and status updates related to payment events across different systems and services. • Refactored existing systems to reduce dependency on Salesforce by introducing a dedicated ticket management module within our backend services. This led to an 80% drop in Salesforce license usage, resulting in annual cost savings of nearly ₹2 crore, while improving ownership and traceability of internal workflows. • Owned multiple microservices in the payment infrastructure ecosystem, ensuring they were optimized, secure, and well-documented. Collaborated with multiple cross-functional teams to align on SLAs, workflows, and integrations. • Enhanced observability and monitoring using Grafana, setting up dashboards and alerting mechanisms to track key system metrics like payment success rates, retries, and latency post-deployment. This significantly improved our ability to respond to production issues quickly. • Utilized Postman for extensive API testing and monitoring, validating contract adherence, inter-service request/response patterns, and edge-case scenarios. This ensured reliability in microservices communication. • Adopted gRPC with Protocol Buffers for inter-process communication to replace traditional RESTful APIs in critical paths, resulting in a 13% reduction in network latency and improved efficiency in data serialization/deserialization. • Implemented key microservice patterns such as the SAGA pattern for distributed transaction consistency across services, and Circuit Breaker mechanisms to handle external API failures gracefully, ensuring high availability and fault tolerance in the system. Technical Skill: •Programming Languages:Java, Python, C++, Apex, JavaScript •Backend and Framework: SpringBoot, Node.js, Microservices, REST APIs •Databases and Caching: MySQL, PostgreSQL, MongoDB, Redis •DevOps and Tools: AWS, Grafana, Git, Postman

Software Engineer 3 at Walmart, Aug 2026 - Present · 3 mo, Bangalore

Software Engineer at Livspace, Aug 2025 - Aug 2026 · 1 y, Bengaluru, Karnataka, India, I own and drive backend features across order, pricing, and finance workflows, working on systems that directly impact business correctness. I led the Negative Wallet initiative, handling item cancellations and preventing financial inconsistencies through schema design, API changes, and cron updates across multiple services. I designed and implemented new database tables and CRUD APIs to persist cancellation requests and ensure correct downstream behavior for procurement and finance systems. I debugged and fixed critical data integrity issues caused by multiple update paths on product item tables, preventing inconsistent quantity and status propagation. I improved platform reliability by adding validations, structured logging, and failure diagnostics for external API integrations. I worked on cross-service integrations including pricing versioning, zone-based BOQ pricing, and design system integrations to ensure deterministic pricing across creation, cloning, refresh, and expiry flows. I collaborate closely with product, finance, and frontend teams to deliver backward-compatible, production-safe changes.

Software development Engineer 1 at Rupeek, Jun 2023 - Jul 2025 · 2 yrs 2 mos, Bengaluru, Karnataka, India, I designed and built an event-driven payment ledger system using NestJS, MongoDB, Kafka, AWS SQS, Redis, and Docker, ensuring 100% reliable logging of payment events across 10+ lending partners. I improved payment processing latency by ~10% through Redis caching, asynchronous Kafka consumers, and database query optimizations. I implemented retry, failure-handling, and DLQ mechanisms to safely recover from gateway timeouts and transient failures without double processing. I reduced Salesforce dependency by ~80%, migrating workflows to internal microservices and saving significant operational costs. I implemented gRPC with Protocol Buffers for inter-service communication, reducing latency in high-throughput flows. I owned production incidents and postmortems, and improved observability using Grafana dashboards for high-RPS payment systems.

Software Engineer at XQuantum Pvt Lim, Jan 2023 - May 2023 · 5 mos, Bengaluru, Karnataka, India, • Build Python backend applications, integrated databases and optimized server-side performance. • Acquired profound expertise in implementing RESTful APIs, architecting database schemas, and refining code for maximum efficiency and performance. • Learned API integration with efficient manner while kept track on cost burning.
