About

I am currently pursuing a Ph.D. in Computer Science at Texas A&M, where my research focuses on designing efficient streaming algorithms. My passion for algorithms and their complexity drives my academic journey as I aim to develop innovative solutions that can shape the future of computing. Having spent significant time in the software industry as a backend developer at Tesco Bengaluru, I have had the opportunity to work with technologies like Java, Spring Boot, REST APIs, Kafka, ElasticSearch, Couchbase, and Microsoft Azure. This hands-on industry experience has given me a unique perspective on computer science, allowing me to approach my research from practical and real-world angles. I am passionate about applying my research skills to solve real-life problems and bridge the gap between theory and application. My goal is to design solutions that advance the field of computer science and have a tangible impact on industries and society as a whole.

Designed and developed microservices in Azure to deliver tailored questionnaires to 30,000 Tesco Tills across the UK via a resilient messaging system, enabling unprecedented visibility into customer checkout experiences.
Led the onboarding and deployment of 300 new Tills and supporting cloud infrastructure in the Republic of Ireland (ROI), enabling regional survey delivery. Migrated and synchronized legacy review and survey data, and introduced a tagging system to ensure accurate data validation and consistency across the Tesco Analytics Platform.
Enhanced Tesco’s customer review systems across multiple regions by upgrading the Review Delivery API for high performance, delivering localized review features for Hungary and Slovakia, and building robust synchronization mechanisms for moderated reviews in the Czech Republic (CZ), ensuring only approved reviews appear on Tesco’s platforms.
My other contributions to the platform include but are not limited to the following:
1. Implemented a Spring Batch module for UK grocery product feed generation, replacing legacy logic and integrating Redis caching for rapid and accurate rating delivery on product listing pages.
2. Integrated inter-service communication across cloud applications, including APIs for product ratings and remote Till applications, ensuring seamless interaction with backend microservices.

Graduate Software Dev Engineer

Sep 2020 – Sep 2022 · 2 yrs · Bengaluru, Karnataka, India

Designed and implemented a microservice in the Azure cloud that receives customer feedback from Tesco Tills. A Tesco Till enables store customers to complete their order checkout with the assistance of a colleague or self-serve. In my work, I delivered a bulk API that collects, processes, and transfers customer survey responses about their checkout experience to an analytics platform.
Developed features to help deliver native (Tesco-owned) and syndicated (reviews collected through syndication) reviews to the Republic of Ireland Tesco online website. I contributed extensively to the integration of our platform with a third-party vendor that provides reviews, especially syndicated reviews. This integration was achieved through communication with their public APIs and sharing of a product feed over SFTP server.
My other contributions to the platform include but are not limited to the following:
1. Developed alerts and dashboards for both the cloud (using Splunk - power user access, Azure alerts) and on-premise Tills Components (using Prometheus and Grafana).
2. Redesigned review report inappropriate API to reduce human moderation workload.
3. Developed archival scripts to archive and anonymize post-purchase email data to comply with GDPR rules against storing data older than a specific period.
4. Contributed to the integration of applications with NewRelic.
5. Have contributed to multiple migration activities and have resolved discrepancies in data consistency seen in the database.
