I build practical software for businesses, teams, and entrepreneurs: public websites, internal tools, CRM integrations, AI-assisted workflows, and full-stack applications that turn manual work into cleaner systems.
I focus on the workflow behind the request, then build software that saves time, improves clarity, or opens a new channel for the business.
From planning and UI to APIs, deployment, and support, I can carry a project from idea to working product.
Many of my strongest projects remove repetitive work by connecting CRMs, cloud storage, calls, reports, and custom dashboards.
Freelance Projects
These projects show the range of my solo full-stack work, from public websites to subscription platforms, productivity apps, and business tools.
Full-Stack Developer
A daily leads subscription platform for real estate wholesaling leads.
Created a focused subscription experience that supports recurring lead delivery and gives wholesalers a clearer way to access daily opportunities.
Full-Stack Developer
A browser-based productivity tool for call-focused work, note-taking, and audio recording workflows.
Helped users keep call notes, recordings, and context in one focused workspace instead of jumping between scattered tools.
Full-Stack Developer
A real estate deal calculator that helps investors evaluate offers and run property numbers faster.
Reduced manual deal analysis by turning repeat calculations into a guided workflow for faster investment decisions.
MaxDispo Dashboard
Deal Dashboard
Full-Stack Developer
A real estate deal management dashboard for tracking deal stages, team feedback, notes, photos, contracts, and updates.
Gave users a clearer way to follow each deal from submission to review, keeping updates and team feedback in one organized workspace.
AccountabiliBuddy
Pairing App
Full-Stack Developer
A school group accountability app where members can join a queue and get matched with another opted-in partner.
Turned a simple accountability idea into a guided pairing flow that helps community members stay connected and follow through on goals.
Teacher Ada
Tutoring Site
Full-Stack Developer
A clean, approachable website for a tutoring service designed for parents and students.
Gave the tutoring business a professional online presence and made it easier for interested families to learn and connect.
Full-Stack Developer
A professional web presence for an IT solutions company offering services like CCTV, cabling, and technical support.
Helped the business present its services clearly online, improve credibility, and create a stronger destination for client inquiries.
POS Badjetz
POS System
Full-Stack Developer
A web-based point-of-sale system built for managing daily transactions, sales activity, and business operations.
Centralized sales tracking and reporting so the business can manage transactions with less manual work and better visibility.
Non-Profit
Unpaid builds for a community that needs real software but has no budget for it. The constraints are tighter than paid work, not looser.
United Pentecostal Church — Conner, Apayao
Sole Engineer
A public website for a rural church congregation and a self-service admin portal that lets church staff run it without a developer.
Built pro bono under three hard constraints: a permanent zero hosting budget, staff who are not developers, and a congregation that reads the site on mobile data. Those constraints shaped nearly every technical decision.
Row Level Security is the authorization boundary, not the app. Every TypeScript guard is a convenience that returns a clean redirect — delete one and PostgreSQL still refuses the request.
A storage ledger reserves space after image compression and before the upload lands, so a church with no card on file can never quietly exceed a 10 GB bucket.
145 tests across unit, database-security and authenticated smoke suites — including one that caught a migration which appeared to lock down storage but did not.
Every screen designed at 360px first with 44px tap targets, because staff update content from the same phones the congregation reads it on.
Independent student publication
Sole Engineer
A public news site for a Grade 6 student journalist, plus a newsroom dashboard where she writes, edits and publishes her own reporting without touching code.
Built so a young writer can present her work like a real publication rather than a school assignment. Because the author is a minor, privacy and security were requirements from the first commit, not a hardening pass at the end.
Bcrypt hashes, HS256 session JWTs in httpOnly cookies, middleware guarding every /admin route and each mutating endpoint re-checking the session itself — so no single check is a point of failure.
The editor scales anything over 1920px on a canvas and re-encodes it as WebP at 82% quality in the browser, so an 8 MB phone photo uploads fast on a home connection and storage costs stay near zero.
No ORM. Pages, route handlers, services and repositories each have one job, with every query parameterized and repositories injected into services so the data layer can be mocked or swapped.
Drafts, publishing, categories, slugs and an audit trail of every create, edit and delete — plus confirmation dialogs and toasts, so the writer always knows what just happened.
