I’m a software engineer with over 3 years of experience specializing in building highly scalable, secure, and distributed backend services with Go (Golang) and Python. I focus on robust API architecture, asynchronous data pipelines, and microservices that perform reliably in production.

At Thoughtworks, I built and operated Kafka-based asynchronous pipelines processing 10,000+ real-time events per minute with 99.9% delivery reliability, deployed as low-latency microservices on Kubernetes and Docker. I improved security and efficiency by enforcing strict JWT/OAuth2 token management and authentication protocols, cutting unnecessary network payloads by 30%, and strengthened distributed transaction handling with secure coding and data modeling. I also boosted observability and reduced issue resolution time by 25% using Prometheus, Jaeger, and advanced log analysis, while delivering sub-50ms real-time synchronization with a concurrent WebSocket service.

Previously, in AI Platform Engineering at IDFC FIRST BANK, I delivered Python-based FastAPI + WebSockets microservices in Docker to power real-time state synchronization with sub-50ms API response times. I reduced manual UI development time by ~40% by engineering LangGraph/LangChain-based multi-actor AI agents and accelerated async task execution by 3x using advanced ThreadPooling—then integrated GenAI tools to save the team roughly 15 hours per week in prototyping.
