A web and mobile system built for Salfer Engineering that helps manage solar site assessments, project monitoring, and billing in one place, so records stay organized and clients get clear updates. It has a React web app for the office and a Flutter mobile app for customers and staff, both running on the same Node.js, Express, and MongoDB backend with REST API.

A web-based tenant admission and billing management system built for local rental houses, designed to enhance rental operations by integrating tenant records, applications, billing, and payment tracking to reduce manual work and improve accuracy. This system combines tenant and administrator dashboards with digital contracts, automated billing, Cash and GCash payment validation, and concern and notification modules on a React, SQLAlchemy, and MySQL platform with REST API integration to deliver organized records and transparent communication, offering a reliable experience for landlords and tenants.

An AI-powered website builder where a customer describes what they want in plain words and gets a live preview in minutes. The generated site can then be edited by hand — text, images, colors, buttons, sections — or improved further through an AI chat, including parts that only appear when something is pressed (mobile menus, pop-ups). Built static and fast: no templates, no bloat, deployed to a live URL. Includes a visual editor, AI chat with web search and image search, and a bring-your-own-key setup for the AI provider.
