Services · When off-the-shelf does not fit
Custom software development (web, mobile, APIs, hosting)
Beyond automation, we build new software: web applications, mobile apps, backend APIs and integrations, and the hosting and deployment to run them, end to end by a small senior team.

Who it is for
- Companies that have outgrown spreadsheets and email for a core process
- Teams that need a customer portal, internal tool or mobile app that no off-the-shelf product fits
- Businesses that need two systems to talk to each other through an API or integration
Typical problems
- A key process runs on a spreadsheet that only one person understands.
- Off-the-shelf tools cover most of the need but not the part that matters.
- Customers or field staff need a simple app, and there is no one in-house to build it.
- An existing app has no one maintaining it, or its hosting is fragile.
What we build
- Web frontends: internal tools, customer portals and dashboards, built to be plain and easy to use.
- Mobile apps: apps for field staff or customers.
- Backend APIs and integrations: services and connections between the systems you already run.
- Hosting and deployment: cloud setup, deployment, monitoring and backups, so it keeps running after launch.
- Handover: you own the code, with documentation your team or another developer can pick up.
How we do it
- Scope. We agree on who uses it, what it must do on day one, what it connects to, and a fixed price before any code is written.
- Build. We design and build it in short steps you can see and try, with the same senior people from first sketch to launch.
- Launch and run. We deploy it, set up monitoring and backups, hand over the code and documentation, and support it if you want us to.
Systems
Tools we commonly use, and similar: Web: React and Next.js, Vue, SvelteKit. Mobile and desktop: Flutter, Tauri. Backend: Python (FastAPI), TypeScript, Rust. Data: PostgreSQL. Hosting: Google Cloud and similar cloud platforms. Already have a stack or a cloud account? We can usually work in it.
Price and engagement
Custom builds are scoped and quoted per project, with a fixed scope agreed before work starts. Smaller builds are scoped like our pilots (fixed scope, 4–6 weeks, $12,000–$20,000); larger ones are quoted after a short scoping conversation, or after a $4,500 process audit if the work touches several teams. Ongoing support is $3,000–$6,000 per month. You own the code.
