Projects
A curated portfolio of independently engineered, production-oriented systems — each built end-to-end from architecture through deployment. These projects demonstrate applied expertise across data engineering pipelines, full-stack application development, and AI-integrated platforms, with a consistent focus on scalability, data quality, and commercial relevance.
A production-deployed charitable trust platform serving the United Digambar Jain Community — live at udjclondon.com. Engineered 12 fully operational modules covering member registration, role-based activity assignment, multi-day event scheduling, rehearsal tracking, and financial reconciliation. Built with Spring Boot 3.2, containerised via Docker, and hosted persistently on Railway with a cloud PostgreSQL instance.
An enterprise-grade CRM and field operations platform engineered for the window & door installation industry. Orchestrates the full service lifecycle — from initial enquiry through site surveys, CAD-linked quoting, workshop production tracking, installation scheduling, and final payment collection. Supports granular role-based access across Admin, Sales, Engineer, and Workshop personas with PDF quote generation and CSV reporting.
A feature-complete Learning Management System built across six delivery phases. Implements a four-tier content hierarchy with teacher-to-admin approval workflows, a seven-type assessment engine (MCQ, Essay, Code, Image-Based), drag-and-drop exam scheduling, and a real-time AI study agent powered by Mistral 7B using RAG over pgvector. Includes auto-marking, class analytics, communications, and a full immutable audit trail.
A production-grade FMCG data engineering pipeline that unifies daily order streams from two independent source companies into a single analytical truth. Implements a Bronze ? Silver ? Gold medallion architecture on Databricks and Delta Lake with schema enforcement, duplicate deduplication, and SLA-driven DQ checks — culminating in a unified fact table and a Power BI executive dashboard delivering actionable sales intelligence.
A streaming ride-hailing analytics engine built on Databricks Delta Live Tables. Auto Loader continuously ingests trip exports from S3, DLT Expectations enforce data quality rules at the pipeline level, and SCD Type 1 CDC upserts maintain driver and vehicle master data with full change history. Delivers city-partitioned Gold views optimised for query performance across 10 major Indian metropolitan regions.
A globally-scoped eCommerce analytics platform processing six interconnected datasets — customers, orders, products, returns, reviews, and shipments — across 7 countries and 7 currencies. A unified FX conversion layer normalises all revenue to INR for cross-market comparison. Governed via Unity Catalog with full data lineage, and surfaced through Databricks AI/BI Genie for natural-language data exploration without SQL.
