At Nielsen I built the Video and Sports MCP servers from scratch as part of the MCP team — end to end agentic AI systems using AWS Bedrock, LangChain, and Neo4j RAGGraph. Reduced video search latency from 4 seconds to under 500ms, achieved 90 QPS with minimal cost, and hit 100% accuracy on ambiguous queries through confidence scoring and LLM verification. Also led chaos engineering, built internal tooling adopted org-wide, and provided active production support.

Crafted RESTful APIs and gRPC microservices using Spring Boot and Neo4j, and applied Redis caching to reduce server load by over 20 percent. Resolved complex issues for DocquityClinic and DocquityCare (Angular, Node.js), enabling on-time launches in Thailand and Indonesia. Built 2 microservices and 1 monolithic project across 2 teams: an AWS-policy-inspired service, a workflow orchestration service, and a doctor-patient platform. Mentored teammates and drove 30+ successful releases, including one microservice deployed end-to-end in 3 hours.

The Payload subsystem will carry out the primary remote observation objective of the satellite. It is the main reason for the satellite to exist, and is supported by all the other subsystems. The main objectives of the payload of this nano satellite is making a hyper spectral imaging system to detect the effects of pollution in different areas of Punjab using a Push broom hyper spectral imager and processing for imagery data.
