## 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 \(DM me or check out Topmate\)
