Business Automation Analyst
Engineered an end-to-end Invoice Processing Pipeline by integrating the Gemini Vision API (OCR) to dynamically extract data from Gmail PDFs. Automated vendor reconciliation, error routing, and historical audits across 15+ vendors, significantly improving accuracy and compliance Engineered a live mobile-responsive web application using Vite, React Query, and shadcn/ui, featuring 30-second real-time data syncs and interactive visualizations (Recharts).
Deployed an ensemble machine learning engine that evaluated 7 key performance variables (including H2H, player stats, and venue) to forecast live, ball-by-ball win probabilities during the WPL 2026 playoffs. During my Data Analytics internship at Burma Burma Restaurant & Tea Rooms, I identified that manually compiling, formatting, and auditing monthly statutory filings across 15+ outlets was consuming critical administrative hours and creating operational bottlenecks.
To solve this end-to-end, So, I built an HR Statutory Compliance Engine & Real-Time Notice Portal to automate the complete workflow. āļøš

What I particularly enjoyed about this project was solving the problem at the intersection of Data Analytics + Automation + HR Operations + Regulatory Compliance.
It reinforced an important lesson for me:
Good automation isn't just about reducing clicks it's about building a reliable process that people can trust.
This project strengthened my interest in building data-driven business automation solutions that create measurable operational impact. Executive Command Centre & AI Parser
Developed a full-stack app using Google Sheets as a dynamic backend, integrating Workspace APIs to automate schedule syncing and task tracking. I constructed a Gemini 3.1 Flash-Lite AI parsing engine with fuzzy-matching to automatically categorize incoming emails and messages into structured pipelines.
