I’m Souvik Kar, a software engineer who enjoys building reliable backend systems that make APIs faster to validate, easier to integrate, and safer to operate. I’ve worked with Java and modern service frameworks to automate end-to-end API validation for enterprise workflows, benchmark performance on large data extractions, and improve operational confidence through health checks and deployment verification. In addition to API-focused development, I’ve contributed to event-driven integrations using Kafka/ RabbitMQ and supported observability migrations by wiring health checks across the stack. I also build practical tooling for real infrastructure tasks (like NAS/FileNet interactions) and I’m comfortable working in CI/CD environments using GitHub Actions and Linux-based runners.
