What I'm looking for

I'm looking for opportunities to build distributed, cloud-native backend systems and AI-powered products in remote, async-first teams. I'm open to relocating worldwide and require visa sponsorship.

I've built the backend for ONDC Workbench at Wits Innovation Labs, a network-wide integration testing platform used by thousands of Network Participants across 20+ business domains.

I design distributed microservices in Go, Java, and Node.js for transaction processing across e-commerce and finance. I deploy cloud-native applications on AWS and GCP with Kubernetes, Kafka, RabbitMQ, and Yugabyte.

I've also built RAG documentation search, an MCP server for LLM integration, and agentic workflows using OpenAI, Anthropic, and Pinecone. My work helps users query protocol documentation, automate multi-step processes, and validate ONDC compliance before go-live.

Earlier at Coding Ninjas, I delivered Node.js/Express REST APIs and React.js features in a fully remote team. I'm comfortable owning technical documentation, asynchronous sprint planning, and secure API systems using Keycloak, OAuth2, and JWT.
