Message

I've built enterprise Java applications for Zycus Infotech, including an AI-powered negotiation and bidding platform that uses chat-based service requests, NLP, and agent-driven decision logic.

I design Spring Boot microservices and event-driven Kafka workflows, with AWS services including EC2, S3, RDS, Lambda, IAM, and CloudWatch for highly available systems. I've also integrated Spring AI, LLM APIs, RAG pipelines, vector databases, and streaming responses.

Across MSYS Technologies, Persistent Systems, Zensar Technologies, Quinnox, and Tech Mahindra, I've delivered REST services, workflow integrations, testing, production deployments, and technical guidance for small development teams.
