I build and modernize enterprise Angular platforms, design systems, and AI-enabled engineering solutions.

At HCLTech, I lead enterprise UI architecture and frontend delivery for Baker Hughes, PwC, and Electrolux, including industrial asset-tracking portals, secure banking dashboards, and regulatory reporting systems.

I've modernized core enterprise portfolios from Angular 17 to Angular 21 with zero downtime while resolving critical security vulnerabilities. I build reusable, accessible component libraries with PrimeNG, Angular Material, and SCSS, and automate frontend releases through GitHub Actions and Azure App Services.

I also support Java Spring Boot and .NET Core RESTful microservices that power client UI systems, bringing practical cross-stack troubleshooting to delivery teams.

For Baker Hughes, I architected and coded a Python RAG document Q&A assistant using LangChain, ChromaDB, Groq/Llama 3.1, and Hugging Face embeddings so field engineers could query turbomachinery manuals, schematics, and CAD/P&ID diagrams. Across my work, I mentor UI engineers, lead code reviews using SOLID principles, and use AI-assisted workflows to deliver dependable enterprise applications.
