Experience
My professional journey as a Full Stack Developer, collaborating remotely with international teams while delivering scalable applications from Ilocos Norte, Philippines.
Part Time Full Stack Developer
Solar X Canada
October 2025 - Present
Developed a production-ready solar estimation platform for Ontario homeowners using Next.js 15, React 19, TypeScript, and Tailwind CSS v4, featuring an interactive multi-step estimator with Mapbox GL JS integration for precise roof drawing and area calculations using Turf.js. Built a comprehensive backend with Next.js API routes, Supabase (PostgreSQL) database, and integrated external APIs including NREL PVWatts v8 for accurate solar production calculations with region-specific parameters (seasonal albedo, monthly soiling losses), HubSpot CRM for automated lead management, and geocoding services. Implemented advanced features including dual-mode estimation flows (Quick/Detailed), automatic progress saving with localStorage and database sync, complex state management for multi-step forms, intelligent caching system to optimize API costs, financial projection models with 25-year ROI calculations, and a fully responsive landing page with interactive components. The platform reduces estimate generation time to 60 seconds while automating lead qualification and CRM integration, establishing a scalable architecture that serves as the primary lead generation tool with foundations for future AI-powered enhancements.
