What kind of software do you build?
Shopify and BigCommerce stores, apps, and tools; custom CRMs and internal platforms; and mobile and desktop apps. If it's software, we can likely build it.
How do projects usually start?
With a short discovery call and a fixed-scope proposal. From there we work in tight weekly loops so you see working software early.
Do you build for both Shopify and BigCommerce?
Yes — we're specialists on both. Storefronts, public and custom apps, checkout logic, and back-office tooling on each platform.
Can you work with our existing team?
Absolutely. We slot in alongside in-house developers and designers, hand off clean code, and document as we go.
What's your tech stack?
Mostly TypeScript end to end — React on the frontend, Node on the backend, native mobile and desktop wrappers, and cloud infra tuned to the project.
Do you offer ongoing support?
We offer retainers for maintenance, performance work, and new features after launch — or a clean handover if you'd rather run it yourself.
