• Designed and shipped 50+ RESTful and SOAP API endpoints using ASP.NET Core Web API, integrating Sales, POS, reporting, and delivery platforms across a multi-brand restaurant group — reducing inter-department data handoff time by 40% and eliminating manual sync processes.
• Engineered 2 third-party delivery platform integrations (Foodpanda/Delivery Hero, InDrive) end to end — built webhook receiver, OAuth login, order acceptance/rejection callbacks, and JWT-secured inbound order ingestion from Delivery Hero POS middleware, enabling fully automated order routing from delivery apps to the kitchen.
• Built and published a cross-platform loyalty app (Polymath Coffee) to Google Play and Apple App Store using .NET MAUI — serving 1000 + active users with native Google/Apple Sign-In (PKCE), QR member card, Firebase Cloud Messaging push notifications, Google Maps branch locator, and a GitHub Actions CI/CD pipeline for iOS builds on cloud macOS runners.
• Engineered a RAG-based reporting engine converting natural-language and voice prompts into SQL Server queries via a 3-phase LLM pipeline (local Ollama routing → ~3,000-token context assembly → cloud LLM SQL generation), cutting report generation time from hours to under 30 seconds and reducing manual reporting effort by 60%.
• Deployed a .NET MAUI kitchen display system across 9 restaurant branches on Android tablets and TV screens — 5-second SOAP polling with diff/merge order updates, 8-band color-coded prep timers over a 20-minute window, and per-branch JSON-persisted settings for independent branch configuration.
• Built Blazor Server internal portals used by 70+ staff — operational approval workflows, loyalty analytics dashboard, CEO-facing live KPI dashboard with Chart.js visualizations and Google Ratings API integration, and route-level role-based access control via ProtectedLocalStorage; improved workflow completion time by 25%.
• Built a .NET MAUI POS ordering app (tablet + mobile variants) with multi-level menu navigation, cart management, multi-payment-type billing, KOT generation, and ESC-POS receipt printing via integrated thermal printers — improving order accuracy by 35% and reducing service time by 20%.
