Currently at OLA Krutrim as a Backend SDE\-1, I work on production cloud\-native infrastructure — NUMA\-aware VM scheduling on OpenStack, VPC services, Load Balancers, and Auto Scaling Groups\. In 6 months, I've: → Reduced memory over\-provisioning by 20% → Cut API response latency by 25% → Helped bring incident escalations down by 40% → Maintained 80%\+ test coverage on critical code paths These aren't resume numbers\. They're what production systems teach you when things go wrong at scale\. My core stack: Java · Spring Boot · Go · Microservices · Docker · Kafka · Redis · PostgreSQL · AWS · OpenStack\. I'm drawn to distributed systems problems, concurrency challenges, and backend architecture decisions that matter under real load\. Before Krutrim, I built a Unified Access Management system at Inventeron Technologies — optimizing MySQL queries, designing RESTful microservices, and implementing JWT \+ RBAC security that eliminated 100% of unauthorized access incidents post\-deployment\. On the side: I published research on image compression at NIT Patna under Prof\. Amit Kumar Singh \(Top 2% scientist globally\), and led development of QuickTongue — the world's first tongue\-controlled game, combining computer vision, AI, and HCI for assistive technology\. Competitive coding: 1100\+ LeetCode problems, rating 1704 \(Knight\)\. I solve problems because I genuinely enjoy the craft — and it shows in how I debug production issues\.
