Aditya Atri

Summary

- Currently leading the development of the CCMS Experience Layer, a high-performance API orchestration layer that standardizes responses from core transaction processing systems and third-party backends, ensuring seamless integration with front-end applications and downstream services. - Set up the load testing infrastructure and benchmarked microservices to achieve specific TPS targets. Achieved 10K TPS with auth transactions p95 latency under 800ms through performance tuning and optimizations. - Load-tested 1M+ credit card billing transactions, ensuring scalability and reliability under high-volume workloads.

Summary

- Led multiple backend initiatives, driving scalability, reliability, and performance optimization through architectural discussions and best practices. These initiatives involved designing and building core capacity systems, partners availability management, and other critical backend components. - Actively participated in bugs-triaging, on-call rotations, diagnosing and resolving production issues to improve system stability. Maintained detailed technical documentation to streamline knowledge sharing and on-boarding. - Collaborated closely with stakeholders to define clear technical requirements, ensuring alignment between prod- uct and engineering goals. Took initiative in breaking down complex projects, effectively distributing tasks, and driving timely, high-quality deliveries. - Developed and implemented key projects, including a quota-based leave management system to reduce op- erational dependencies, a capacity reservation system that improved rebooking rates by 17%, and a data-driven reliability model that reduced NR-FBCE requests by 2%. Spearheaded backend migration to the Orion framework, optimizing performance and reducing p95 latency by 1.5s while minimizing request loss by 2.5%. Built an A/B testing framework from scratch for controlled feature rollouts, and introduced slot surge pricing, generating an additional 2 Cr+ in revenue per month.
