Engineering leader at VLink India building RAG solutions for code review, defect analysis, and knowledge retrieval.

At VLink India Pvt. Ltd., I lead cross-functional engineering teams and drive database remediation from Sybase to MS SQL. I also implemented LLM solutions with RAG for code review, defect analysis, and knowledge retrieval.

I built an AI-driven code review assistant integrated with GitHub and GitLab pipelines. It detects security vulnerabilities, performance issues, and coding-standard violations, and automates review comments and suggested fixes.

At EPAM Systems India Pvt. Ltd., I supported Perl-based web services and REST APIs, investigating production defects across UI, API, and PostgreSQL databases. At Shipco IT Pvt. Ltd., I developed solutions from client requirements and Jira tasks and supported QA validation.

Earlier, I led a Broadbean client integration project at IKOKAS Digital Technologies, and developed Perl applications and automation for publishing workflows at SPI Global (Straive) and Aptara International Pvt Ltd. I also led template development and automation projects at Thomson Press India Ltd.
