Kishan Kumar — Software Engineer

I am a Backend Software Engineer with over five years of experience at PhonePe, where I specialize in building high-performance, resilient infrastructure for one of India's largest fintech platforms. My expertise lies in high-throughput API gateways, automated configuration management, and optimizing distributed systems to handle millions of requests per second. I graduated from the Indian Institute of Technology (IIT), Roorkee with a B.Tech in Electrical Engineering and a Minor in Computer Science. Core Impact & Engineering Milestones: Gatekeeper (API Gateway Config Platform): I engineered a self-serve configuration management platform from the ground up to replace manual YAML onboarding for over 700 microservices. By implementing a dynamic polling model and automated sanity checks, I slashed the API onboarding cycle from a 48-hour batch window to under 5 minutes, a 99.7% reduction in delivery time. Dynamic Resilience: I designed an adaptive load-shedding protocol that preemptively aborts 40% of non-critical traffic during surges, shielding backends from cascading failures without exposing internal topology. Infrastructure Optimization: I led a critical initiative to resolve event-loop blocking by offloading I/O-intensive Aerospike operations to Vert.x workers. This architectural shift allowed us to shrink our internal API fleet from 200 to 25 instances (an 87.5% reduction), saving over 2,700 CPU cores and 2.8 TB of RAM while significantly increasing throughput. Primer (Auth Systems): I managed the Primer JWT system, which handles over 70,000 token operations per second with low-latency flows backed by Aerospike and DPoP cryptographic binding for enhanced security. Current Focus & Technical Reach Currently, I am focused on scaling Loki, a logging framework designed to handle the massive volumes of daily logs generated at PhonePe. This involves optimizing data ingestion and storage to ensure observability remains cost-effective and performant at extreme scales. Beyond core backend engineering, I have a strong interest in AI-driven automation. I recently architected Intellibot, a Slack-integrated RAG pipeline that utilizes OpenAI embeddings and a ChromaDB vector store to automate the diagnosis and resolution of recurring on-call issues. Beyond Engineering: I am a student of history and philosophy, with a particular interest in the cosmos and macro-history (such as Harari's Sapiens). I also maintain a technical blog at 0xkishan.com where I explore the intersections of blockchain, AI, and backend architecture.
