💼 Experience
- Led the development of Visa's global on-call alerting and incident resolution platform, serving engineering and SRE teams across a payment network processing 60,000+ TPS and 200M+ daily transactions.
- Architected real-time alert routing system (Angular, Node.js, TypeScript, Python, MySQL) with Microsoft Teams integration, reducing MTTR by 20% across multi-region infrastructure.
- Designed multithreaded fleet diagnostics engine (Java, Spring Boot) at 1,000+ ops/sec with sub-60ms P99 latency for automated root cause analysis.
- Building a Site Reliability GenAI Agent using LangGraph, LangChain, and LLMs (GPT, Gemini) for automated root cause analysis, predictive change detection, and SOP recommendation — reducing manual investigation time by ~70%.
- Authored open-source internal libraries for cryptographically secure inter-service communication (TLS, AES-256, certificate pinning).
- Built class search and student registration systems (React, Next.js, TypeScript, Node.js, SQL Server) with accessible technologies (WCAG 2.1, ARIA) and CI/CD automation, reducing operational overhead by 25%.
- Optimized database performance 30% via query refactoring; achieved 99.999% uptime through Prometheus/Grafana observability.
- Built synthetic monitoring for Kafka pipelines (Angular, Node.js, Go, Prometheus, Grafana), improving reliability 30%.
- Engineered real-time anomaly detection pipeline (Kafka, Druid, Prometheus TSDB) processing terabytes of infrastructure metrics.
- Shipped config management tool (Java, Redis, MongoDB) that cut support requests 50%.

🛠 Technical Skills
👋 About
Hey! I'm Rishav Kumar — a software engineer based in Austin, TX. I grew up in India and moved to the United States at 18 to pursue my Bachelor's degree in Computer Science at Arizona State University. Moving countries alone to chase something you're passionate about is equal parts terrifying and exciting — I wouldn't trade it for anything.
During my undergrad I interned at Visa twice, building synthetic monitoring systems and real-time data pipelines with Kafka and Druid. I stayed at ASU for my Master's, and joined Visa full-time after graduating. I'm now a Senior Software Engineer working on AI-driven observability platforms — building real-time alert resolution and notification systems for on-call teams, AI agents that run health checks on servers and automatically detect problems before anyone notices, and a lot of Angular and Node.js work connecting it all together.
Outside of work, I play guitar and sing — mostly when nobody's listening, sometimes when they are. I also love cooking, which I picked up seriously after moving to the US. What started as survival cooking has turned into something I genuinely look forward to.
