About

👨‍💻 About Me SDE 2 with 2 years of experience building scalable, low-latency systems in high-growth environments. Passionate about backend engineering, system design, and solving real-world problems through technology. Currently at Dream11 as an SDE 2, I work on the multi-tenant Offers Platform — owning critical APIs (handling 6.5M RPM, p95 ~6ms), leading schema and service design, and driving performance optimization via load testing tools like Torque (Gatling). Scaled services to handle 35M RPM in real-time match scenarios, reducing product go-live from 60 to 15 man-days and saving substantial engineering bandwidth. Previously at OneCard, I contributed to core banking simulators, transaction frameworks, and automations that enhanced system robustness and saved operational costs. During my Microsoft Engage internship, I delivered collaborative features for Android OneNote, working across ODSP services despite limited prior Android exposure. 💡 I thrive in fast-paced, collaborative environments where I can contribute to impactful systems, mentor others, and continuously grow in distributed systems, backend architecture, and cloud engineering. 🛠️ Tech Stack: Java, Vert.x, Kafka, DynamoDB, AWS, PostgreSQL, Hibernate, React.js 🏆 Knight on LeetCode, 4⭐ CodeChef, Top 100 – Microsoft Engage 📬 Open to 1:1 mentorships, mock interviews, and resume reviews (DM me or check out Topmate)

Architected MySQL schema and team movement flow for Dream11's season-long multi-match fantasy format, enabling persistent squad management, variable cadence team edits (per-match, weekly, or none), and boosters — a greenfield product distinct from the traditional single-match model.
Engineered APIs for real-time points distribution across concurrent live matches in a tournament, maintaining p99 < 25ms; used Spark to bootstrap leaderboards live within 1 minute of match lock with transfer windows opening within 15s.

Service owner of the multi-tenant Offers Platform, architecting offer logic abstraction to reduce go-live
effort from 60 to 15 man-days. Maintained 99.99%+ uptime during IPL/World Cup seasons serving
6.5M+ RPM (p99 12ms) using Vert.x, DynamoDB, and Kafka.
Led DynamoDB schema design evaluating alternatives (Aerospike), architecting partition strategies with
cost-performance analysis, achieving 60% cost reduction (measured vs similar production services) while
maintaining low latency and efficient queries.
Spearheaded service optimization via Gatling-based load testing (Torque), scaling from single-instance
benchmarks to 35M RPM simulating real-time match flow, improving system throughput by 40%.
Improved service observability by implementing comprehensive monitoring dashboards and alert
optimization using Datadog, reducing false alerts by 20% and incident resolution time by 40% through
refined thresholds and actionable metrics.
