Real, shipped case studies below — travel booking and enterprise admin platforms. More get added as new work ships, no filler entries.
Built and maintained a full travel reservation platform end to end: flight and hotel search, multi-supplier GDS integration, automated refund workflows, and an internal admin panel for booking management, audit logs and wallet handling.
Backend on ASP.NET Core and SQL Server, frontend in React, with Dapper-driven reporting endpoints handling high-volume search traffic without the database falling over. A stored-procedure-heavy date-search flow was later rewritten to fix severe tempdb bloat — cutting load on the database under peak traffic.
Sole developer across the entire stack: backend, frontend, database design, and ongoing maintenance.
For a large manufacturing enterprise, rebuilt a sprawling internal setup into a single department-wide admin portal — restructured for a cleaner, faster experience across teams that previously juggled disconnected tools.
At its core: a new Product Library. Designed the full SQL Server schema in dbdiagram.io, migrated all legacy data into it, and indexed everything in Apache Solr for near-instant product search — then exposed it through C# APIs consumed by internal apps and third-party tools alike.
Also shipped a desktop tool that auto-generates PowerPoint decks straight from Excel, wiping out hours of manual report-building for the sales and design teams.
Operator-facing dashboards and back-office consoles across travel, logistics, retail, finance, healthcare, HR and SaaS. Each is a working interactive demo on sample data — not a real client's data — so you can open it and use the search, filters and sorting directly. My real client builds are login-gated, so I walk through those live on a call.
