Our work
Client work we protect. Products we run ourselves.
Most of what we build is for clients who need it kept private, so their names, screens and figures stay under NDA. Below is the kind of work we deliver for them, followed by products we designed, built and operate under our own name, which you can open and inspect today.
Client engagementsConfidential under NDA
SaaS & web platforms
Subscription software, customer portals and admin panels with accounts, roles, billing and reporting, built to be handed over and extended.
Mobile applications
iOS and Android apps from one codebase, with the backend, admin tools and App Store and Google Play release handled end to end.
E-commerce & integrations
Online stores, payment flows and connections between ERP, CRM, accounting and marketplace systems, so orders and data stay in sync.
Client names, screens and figures are never published without written permission. Where our agreements allow, we can walk you through relevant work on a call. Talk to us about similar work →

How a project runs
Clear scope. Visible progress. No surprises.
Every stage ends with something you can review: a document, a prototype or working software on a staging URL you can open at any time.
- Discover & defineUsers, constraints and goals turned into a written scope with acceptance criteria, a timeline and a fixed quote.
- Design & validateFlows, interface designs and architecture reviewed as a prototype before the full build is committed.
- Build & integrateWorking increments on staging, documented decisions and testing against the agreed criteria.
- Launch & evolveProduction deployment, store submission, source-code handover and documentation. Support scoped to your needs.
What you can count on
Hiring a software studio, without the guesswork.
Most risk in outsourcing is not the code. It is scope, ownership and communication. These terms are written into every BBR proposal and contract.
A price before you commit
Discovery ends in a written scope with acceptance criteria, a timeline and a fixed price tied to milestones. Nothing is billed until you agree.
Your code, your accounts
The contract assigns the code and IP to you. Hosting, domains and store accounts are registered in your name from day one.
Progress you can open
Working increments on a staging environment you can use at any time, plus regular written updates on what is done, next and blocked.
Direct access to engineers
You talk to the people building your product, in English, at meeting times fixed around your time zone.
Changes priced openly
Each change is written down with its effect on cost and timeline, and work proceeds only once you approve it.
No lock-in after launch
You receive the repository, credentials and documentation. Continue on a monthly plan, take the work in-house, or pause.

Before we begin
Questions clients ask first.
Still unsure about something? Ask us directly; a person replies by email.
What kind of software can you build?
We scope custom web platforms, SaaS, mobile apps, AI integrations, Web3 and DeFi applications, PC and mobile games, and connections between business systems. Feasibility, deliverables and specialist requirements are established during discovery.
Can you join an existing project?
Yes. We can review an existing codebase, add a feature, connect an API or plan a staged modernization. Share the stack and your priorities when you contact us.
How much will my project cost?
Cost depends on the scope, existing systems, integrations and release requirements. Send a short brief with your desired timeline and budget range so we can discuss a realistic delivery approach. To estimate it yourself first, see our guides to MVP cost and mobile app cost.
Do you work with US and European teams?
We welcome international projects and plan communication in English, shared documentation and meeting windows around the project’s time zones.
Who owns the code and what happens after launch?
You do. The contract assigns ownership of the code and deliverables to you, and you receive the repository, credentials and documentation. After launch you can continue with us on a maintenance or iteration plan, move the work in-house, or pause. How we work covers ownership, handover and support in detail.
Can we see work you have done?
Most of our client work, across crypto and DeFi, SaaS platforms, mobile apps and e-commerce integrations, is covered by NDA, so we do not publish client names or screens. Where our agreements allow, we can talk you through relevant projects on a call. Our own products are public: MarketsGrid, altingumusfiyatlari.com and the Live Gold & Silver Prices app on Google Play, each with a write-up of how it was engineered.
What happens after I send a brief?
A person reads it and replies by email, usually with a few clarifying questions. If it looks like a fit, we arrange a call at a time that suits your time zone, with an NDA first if you want one. You then receive a written proposal with scope, approach, timeline and price. Nothing is billed until you agree to it.
Your next move
Tell us what you want to build.
Send a few paragraphs about the product, the users and your timeline. We reply with questions, then a written proposal with scope, timeline and price.
