About Me

I’m a backend engineer who enjoys designing and building systems that work reliably in production. I build dependable backend platforms—from workflow orchestration and Kafka-based asynchronous processing to microservices running on Kubernetes. I also build AI-enabled backend capabilities with RAG, knowledge graphs, and LLM APIs. I enjoy turning complex production problems into measurable, maintainable systems through thoughtful design, observability, and automation.

Primary: Golang, Python
Messaging: Kafka
Platforms: Kubernetes, IBM Cloud
Reliability: Prometheus, Grafana, pprof
AI Backends: RAG, Neo4j, LLM APIs

Infosys Limited
Building a cloud-native orchestration platform with distributed workflow execution, secure service communication, and an observability-first reliability focus.
  • Designed and developed a Router Service for multi-phase product-dimensioning workflows, including dependency resolution, task decomposition, and distributed execution.
  • Implemented asynchronous Router-to-Executor communication using Kafka producers and consumers, with retries and timeout control for reliable workflow execution.
  • Developed an Executor Service to manage engine lifecycle, including timeouts, retries, error propagation, and WASM modules sourced from OCI registries.
  • Optimized MariaDB persistence for workflow metadata and orchestration state with efficient SQL and Go data-access patterns.
  • Implemented mutual TLS for secure inter-service communication across Kubernetes and data layers.
  • Improved observability with Prometheus, Grafana, Kubernetes health probes, and pprof profiling; added vulnerability checks and CI coverage gates.
