Web applications
Customer portals, booking systems, dashboards. TypeScript, React and Node, deployed to AWS.
Custom software, built properly
Software that fits the way your business actually works.
We build web applications, internal tools and AI integrations for small and mid-sized teams — fixed-price milestones, no hourly surprises.
The chat bubble in the corner is Stonelink Assist — the product below, running live.
What we do
Internal tools
The spreadsheet that has quietly become business-critical, rebuilt as something your team can rely on.
AI integrations
Assistants, extraction pipelines and automations grounded in your own data — not generic chatbots.
How an engagement runs
- Discovery call. Thirty minutes, free, no pitch. We scope the problem before anyone talks about price.
- Written proposal. Within two business days, with fixed-price milestones so the total is agreed up front.
- Build. Most projects run four to twelve weeks, billed per milestone as each one lands.
- Launch and support. Thirty days of post-launch support included; a maintenance retainer after that if you want one.
Stonelink Assist
The assistant on this page is our own product. You train it by talking to it — like briefing a new employee — and it answers your customers from what it has been told. When it does not know something, it says so and logs the question for you.
Installing it on any site is one tag:
<script src="/widget.js" data-tenant="stonelink" async></script>That is the exact tag running on this page — nothing about this demo is special-cased.
