Designed and developed a full-stack mall digitalization platform from scratch, including a PWA frontend, admin panel, and RESTful backend services. Built scalable backend systems using Go (Golang) with a modular, reusable architecture, ensuring clean separation of concerns and service reusability. Implemented secure role-based authentication and access control with JWT for mall admins, shop owners, and customers. Developed an interactive admin dashboard and PWA using React with TypeScript and TanStack Router/Query, supporting real-time catalog editing and item browsing. Integrated Google Cloud Storage (GCS) for image uploads and Gemini AI for intelligent menu parsing, including CSV import with validation and preview. Enabled advanced catalog features including shared cart support, multi-shop navigation, category-based filtering, and seamless onboarding flows.

Designed and developed a geospatial telecom infrastructure platform from scratch, enabling dynamic tower location analysis and communication site planning. Built an interactive frontend using React, TypeScript, Tailwind CSS, and Shadcn, with features like real-time tower visualization, signal coverage overlays, and parcel boundary analysis. Architected and implemented a high-performance Golang signal analytics server with database indexing and Gin, reducing data fetch time from 8 minutes to 30 seconds (93% faster). Created a CRM for parcel data from scratch, removing dependency on Excel and streamlining the site acquisition workflow. Integrated mapping tools such as Google Maps API, Regrid parcel data, and geospatial utilities for precise location insights and engineering analysis. Implemented frontend tools for drawing overlays, selecting tower configurations (Guyed, SST), and visualizing FCC data using scraped and API-fetched datasets.
