Is it the right fit?
Best when
You need to launch a product, replace brittle internal software, extend a platform or modernize a legacy application.
Not for
Off-the-shelf problems. We will say so if a SaaS tool is the better answer.

What have you built with this?
Commerce with live ERP sync for Phillip Jeffries, HIPAA telemedicine for UVOHealth, SMS marketing for Shopify merchants at YipSMS, visa screening for application-esta.co.uk, plus test-prep, marketplace and booking platforms. All are on the work page.
How long does it take to build an MVP?
Typically 8–12 weeks. Larger platforms are built in phases, with working software at every review.
Can you embed engineers in our team instead of running a project?
Yes. That is its own service, Dedicated engineers: senior engineers work inside your repositories, stand-ups and roadmap, with the same written scope and weekly review.
Which technologies?
Ruby on Rails, Node.js, Python, React and React Native, PostgreSQL, Redis and AWS most often. We choose for the problem and for your team’s ability to maintain it.
How do you handle scope changes?
Scope is agreed in writing. Changes are quoted before work starts, and if we discover the plan is wrong we say so early.
How much does custom software development cost?
We don’t publish prices. Scope and price are agreed in writing before work starts, after a 30-minute call, so the number matches your project.
Do we own the code?
Yes. Repositories, infrastructure and documentation sit in your accounts from the first day.
