Engineering consultancy
Engineering partners
for the hard parts.
BuiltFast is a senior engineering consultancy. We design, build, and scale web apps, hosting platforms, billing systems, APIs, and AI-driven automation. And we lead the teams that keep them running.
20+ years shipping platforms · web apps · billing · APIs · automation · fractional leadership
We've built and operated hosting platforms at A2 Hosting, Site5, Pressed, and Envato.
How we move the work forward.
From a single rewrite to a platform you license to others. We take on the parts of building software that are hard to hire for and harder to get right.
Web & App Development
Greenfield builds, rewrites, and scaling for web apps that have to hold up under real load.
Learn morePlatforms & Hosting
Multi-tenant control planes, user dashboards, and the infrastructure to keep it all running smoothly.
Learn moreBilling & Dashboards
Subscriptions, custom order forms, multi-brand billing, and the reporting to make sense of it all.
Learn moreAPIs, CLIs & SDKs
REST APIs, SDKs, and CLIs with reference docs generated from the code — and an interface an agent can drive.
Learn moreAutomation & AI Workflows
The work that breaks when someone forgets — provisioning, deploys, certificates, backups — made reliable and invisible.
Learn moreFractional Leadership
Fractional CTO / VP engagements and agile delivery for teams that need senior direction.
Learn moreSenior engineers, embedded in your delivery.
Three ways to work together. Whichever fits, the people you meet are the people who build. Nothing gets handed off to juniors.
Project work
Fixed-scope builds and rewrites delivered end to end, from discovery and architecture design through launch. You get a defined outcome, a date, and code documented for whoever owns it next.
Learn moreOngoing partnership
We join your team and ship alongside it — writing code, reviewing PRs, and owning systems with you. Same standups, same board, same repo, and the practices stay after we go.
Learn moreFractional leadership
Fractional CTO / VP direction to set architecture, process, and hiring while you scale your team. Part-time senior direction without the full-time hire.

Vector
A white-label, API-first managed WordPress platform that runs WordPress serverless on AWS Lambda. We built the whole stack — a Laravel control plane that orchestrates AWS, Ymir, and the CDN edge; the per-partner cloud infrastructure; the container images sites are built from; and the open-source CLI and SDKs partners write against.
Read case studyGoCart
A2 Hosting's checkout — the page every sale went through — rebuilt as a Laravel application with no database of its own, talking to a custom WHMCS addon over HTTP. Two years of work, sixteen months live, and a front end owned by a different team on a different cadence, which turns out to be the whole story.
Read case studyTurboHub
A2 Hosting's customer control panel, built alongside the vendor product it was architected to outlive — a Laravel application with no users of its own, a PHAR daemon on every hosting server, and one rule underneath both: never query WHMCS's database, only its API. Two years, twenty-five people, four datacenters.
Read case studyWormhole
Roughly ten thousand customers moved off three separate WHMCS installations and into Helix — one JSON file per record, one brand per maintenance window, and no billing incident anyone had to apologize for. Two and a half years, a team of ten. The interesting part is everything we decided not to carry.
