Built a full-stack clinic management and appointment booking platform for a multidisciplinary healthcare clinic using Laravel and Livewire. The system handles the complete patient journey — multi-clinician appointment booking, live slot availability, consent forms, clinical notes, prescriptions, pharmacy inventory, invoicing, payments, and video consultations. I also integrated Google Calendar, Zoom, e-signatures, multiple payment gateways, and multilingual support across 11 languages.

Built GigResource end to end — a two-sided marketplace connecting event clients with verified professionals. Clients can create detailed requests across 106 event types, receive sealed bids, compare professionals, award services, manage contracts and packages, and handle payments and payouts in one platform. I built the complete Laravel architecture, marketplace workflows, Stripe payment layer, and 1,000+ feature tests covering critical booking and money flows.

A full-stack construction management platform built for an industrial contractor to replace fragmented spreadsheet-based workflows with one centralized production system.
Built a T&M estimating system with crew-based labor and cost/billable rate calculations, GPS-verified field time tracking, per-diem and cost-code allocation, purchase order and commitment tracking, cost reporting, payroll processing, client-facing billing views, and invoicing.
The platform includes 28 modules, 9 permission roles, REST APIs, and print-ready PDF/Excel exports, and was shipped iteratively while being used in daily production.
