About

I am currently working as a Software Engineer at Stripe. Here I am part of the Service Ecosystem and Sustainability team at stripe. Previously I worked as a Software Development Engineer at Flipkart. At Flipkart, I worked on multiple projects, including the scalable features with which users interact in real-time on a large scale. Also, lead track for tech solutions, HLD, LLD and implementation of multi-dc active-active distributed setup for team's core services. Have received multiple recognitions from Flipkart for excellence in executing projects. Hands-on with executing multiple projects end to end, starting from understanding PRD, requirement negotiation, scope finalization, preparing high-level and low-level designs, code implementation, design and code reviews, testing, NFR and productionisation. Apart from Software development work, Just out of interest I have also identified, reported and contributed to fixing security vulnerabilities in Flipkart core services and have received recognition from the organization for this.

Working in the Lockin team, we own the Supercoin loyalty construct and majorly work on Java, Spring boot and MySQL.
Lead track for supporting Multi-DC active-active distributed setup for team’s core services. To support this feature, I worked on preparing and analysing Tech solutions, HLD, LLD, and Database Remodelling. Led design discussions for this project and also worked on code implementation, mentoring of new people on the project, and their code review. This project will help Flipkart to sustain business in case of local and total DC failures.
Worked in the Flipkart Catalog, Homepage and Payments teams as an external resource. On-boarded to their tech stack and code base and implemented changes in their code base to deliver my team’s project. It enabled us to showcase features on the Flipkart product page, homepage and payments page and integrate with the core shopping funnel.
Worked on externalising Supercoin construct outside Flipkart. Collaborated with Myntra for end-to-end onboarding to the Supercoin system, starting from gathering functional and non-functional requirements, designing API contracts and code implementation. This project enabled Myntra to issue supercoins on orders placed on their platform.
During on calls, along with fixing ad-hoc issues I also contributed to increasing the stability and scalability of the system in the long term by adding an in-memory cache registry to reduce database calls from 13K QPS to 300 QPS.
Worked on tech solutioning and implementation for scaling an existing feature from 200 QPS to support 40K QPS.
Just out of interest, apart from development, I identified a critical privilege escalation bug in the Flipkart cloud. Also, identified, reported and designed a fix for a bug in a central system managed by other teams where internal service tokens were exposed.
Organised and delivered Knowledge sharing sessions for projects I worked on and on the technologies I am learning.
