Senior Software Engineer

Dec 2024 – Present · 1 yr 3 mos · Bengaluru, Karnataka, India · Hybrid

As part of Venmo’s Risk Engineering team, I focus on building scalable systems that protect millions of users from fraud while minimizing financial losses for PayPal. My core responsibilities include designing and implementing critical risk variables used by analysts to assess and respond to threats in real-time across multiple decision checkpoints.
Currently leading a key initiative to modernize our risk infrastructure through an event-driven pre-computation and caching framework. This approach enables near real-time availability of computed risk signals by calculating deltas on each event, significantly reducing runtime computational overhead and latency during fraud checks.
My work directly contributes to improving the accuracy, efficiency, and responsiveness of fraud detection systems, supporting Venmo’s commitment to secure and seamless financial experiences.

As a Senior Software Engineer, I consistently delivered new features end-to-end, taking full ownership from requirement analysis to deployment. I collaborated cross-functionally with teams to design, develop, and implement scalable RESTful APIs for microservices, ensuring they met both technical standards and customer needs. My work included optimizing API performance most notably improving the execution time of a key REST endpoint by 95% through Java multi-threading.
I played a pivotal role in a critical Billing Care project, leading the design and implementation of a failure logging mechanism across 100+ state-changing APIs. I was also actively engaged in resolving high-priority customer bugs and provided quick turnarounds with effective solutions.
Beyond backend development, I contributed to frontend initiatives by building UI components for customer-facing notification configuration features. These allowed users to manage and customize subscription behaviors effectively. I also worked on event-driven systems, developing Java-based APIs to push billing and charging notifications to Kafka queues.
My responsibilities extended to participating in design discussions, peer code reviews, and documentation processes. I regularly mentored new team members, conducted onboarding sessions, and supported cloud-based deployments using Docker and Kubernetes.

Associate Staff Engineer

Sep 2020 – Aug 2022 · 1 yr 11 mos

As a Software Engineer, I was actively involved in the end-to-end development of new features across both frontend and backend systems. I contributed to the design and implementation of the Loan Management feature in the REST API Manager for prepaid customers. This feature enabled automatic loan granting when a subscriber's balance was depleted during service usage, and ensured loan recovery upon recharge—providing a seamless user experience while aligning with business policies.
I developed multiple Java-based RESTful APIs to support notification management for Oracle BRM, enhancing real-time communication with customers. I was also responsible for containerizing applications by building Docker images and Helm charts for various web-based products, and further automated their security scanning and testing processes.
My role extended into DevOps, where I set up CI/CD pipelines using Jenkins, Kubernetes, and Helm, enabling smooth and efficient product deployments. With strong experience in Agile methodologies and Behaviour-Driven Development (BDD), I was deeply involved in the design, development, maintenance, enhancement, and debugging of microservices, ensuring robust and scalable software delivery.
