Why the client cases are unnamed
Some clients work with us under confidentiality clauses; others simply do not want competitors to see who their contractor is. So the public list shows the industry, the task and the result. If you need to see a specific site or talk to a client in your niche, write to us: we will show what we can and give you a contact for a reference.
What these projects have in common
All of them: a contract, an estimate before the start, weekly demos and code handed over to the client. Wherever there are sales — Kaspi. Wherever there is search — an SEO structure from day one, not “we'll add it later”. That is our process; more in how we work.
The short version.
Can I get a reference from one of your clients?
Yes. Tell us your niche — we will find a client with a similar task and ask their permission to share a contact.
Do you have cases in my industry?
Possibly. The list above is not everything. Describe the task and we will tell you whether we have done something similar and how it turned out.
Can I see the code?
Client project code belongs to the clients. The open examples of our work are our own products: 1Study, 1Work and this website.
Tell us about the task and we will reply with an estimate and a timeline.
No introductory call required: describe the task in the form or in a messenger, we will ask a few clarifying questions and come back with an estimate. This usually takes one or two working days.
