At Tata Consultancy Services, I delivered 15 production-ready enhancements across Oracle FCCS and TRCS applications, owning the SDLC from design through UAT sign-off with zero critical defects.

I build financial-close and tax-reporting solutions through dimensional metadata hierarchies, consolidation rules, Smart View analysis, and controlled Oracle LCM migrations across Dev, Test, and Production. I also maintain SAP S/4HANA landscapes on Linux, handling upgrades, transport management, incident resolution, and operational KPI monitoring.

As a Google Summer of Code contributor with TARDIS-RT, I engineered Python pipelines for Monte Carlo simulation data and built configurable Matplotlib and Plotly visualizations for supernova research. My work reached over 95% automated test coverage and included nine merged pull requests across the TARDIS-SN open-source ecosystem.

I also built StonX, a full-stack virtual stock trading platform with live market data, portfolio tracking, news, and WebSocket chat.

Google Summer of Code

May 2024 - Oct 2024 (5 months)

Engineered Python data processing pipelines using Pandas and NumPy to transform large-scale Monte Carlo simulation outputs into structured datasets for dual-mode visualization. Built dual-mode visualization (Matplotlib, Plotly) with 11 configurable parameters, enabling astronomers to interactively analyze photon packet interactions across supernova ejecta velocity profiles.

SAP Analyst

Tata Consultancy Services

Maintained 3–5 SAP S/4HANA landscapes on Linux, executing kernel upgrades, parameter administration, and client copies with zero unplanned downtime. Diagnosed and resolved 10–15 system-level incidents per month on Linux servers via SSH, applying root cause analysis and coordinating scheduled downtime windows based on issue severity and scale.
