Custom web apps and SaaS products are full-stack builds on Next.js and Supabase or Laravel and Filament, hosted on Vercel, Cloudflare, Railway or Hetzner.

The Next.js and Supabase stack brings Postgres, Auth, Edge Functions and row-level security, so each tenant sees only its own data. Scoping comes first: SaaS blueprints have covered an MSME operations suite, a government procurement bidding platform and attendance systems, each as a written scope before any code. Repos live in your GitHub organization, docs and runbooks included.

Delivered systems include a radiology structured-reporting SaaS for clinics in Australia and New Zealand, with one deployment per clinic. It carries an insights dashboard, an annotation canvas and a hardware spec for an on-site connector box. A rental-listing platform in Canada moved from WordPress and WooCommerce onto Next.js and Supabase. A Canadian real estate brokerage site syncs MLS data and ships with MapLibre maps. [A directory and citation network](../portfolio/directory-network-portal.md), now in progress, runs Astro sites across many domains with a Laravel and Filament admin portal for staff.

AI coding agents write much of the code, every change ships with screenshots and tests for human review, and nothing goes live without your sign-off. See [the radiology SaaS](../portfolio/radiology-saas.md), [the rental marketplace rebuild](../portfolio/rental-marketplace.md) and [the brokerage website with MLS sync](../portfolio/brokerage-mls-website.md).
