I'm building customer-facing AI solutions at SAP Labs, including query resolver agentic systems, customer briefing generators using LLMs and Perplexity, and XGBoost-based risk scoring.

I develop POCs and custom solutions across the SAP ecosystem, working with RAG and agentic pipelines, MCP servers, AI Core, Grounding Services, BTP Cloud, and S4/HANA systems.

Previously at Tata Communications, I led full-stack development for IZO Private Cloud and IZO MultiCloud products, delivering scalable cloud and network solutions using Angular, Node.js, microservices, and MySQL.

Across EPAM Systems and Accenture, I built analytics portals, data collection applications, micro-frontends, and B2B web products, including reusable UI components that reduced redundant coding by 25%.
