Core contributor to Payroll and Expenses in Alt Worklife (PeopleStrong), working across frontend (Angular 8), backend (Java EE 7 / EJB), and database layers.

• Built a Python microservice that converts raw client paystructure Excel files (format-agnostic) into system-compatible format, reducing support effort and turnaround time
• Created an AI Payroll Agent using Google Vertex AI / Gemini for automated payslip query resolution
• Built the complete Loan Module from zero — EMI engine, foreclosure, and multi-level approval workflow
• Led Investment V3 rewrite used by 1M+ employees
• Built the BRE ecosystem — web, mobile APIs, and outbound integration for a major airline
• Resolved multiple P0/P1 incidents with same-day turnaround

Developed deep learning classification models for volcanic deformation detection using Sentinel-1 SAR satellite data and PSInSAR interferometric techniques under Prof. Debashish Chakravarty (Department of Mining Engineering).

• Implemented and benchmarked CNN architectures (AlexNet, ResNet, Autoencoders) for complex geospatial imagery classification
• Achieved 90%+ accuracy on Sentinel-1 SAR volcanic deformation datasets
• Applied advanced augmentation and transfer learning with pretrained ImageNet weights, improving detection rates by 95%
• Delivered weekly research updates with model metrics, confusion matrices, and architecture comparison insights
