Most businesses don't need six suppliers. They need one person who understands how the website, the app, the admin panel and the server fit together, and builds them to work as one system.

About

Meet Yuriy Sultanov.

I'm Yuriy Sultanov, a professional software developer with over 20 years of hands-on experience building digital products end to end: responsive websites and complex web platforms, native Android apps, Windows desktop software, Python tools and automations, for clients across many different industries.

My approach combines solid engineering with a strong eye for detail: clean, maintainable code, reliable architecture and interfaces people genuinely enjoy using.

Because I work across the entire stack (front-end, back-end, databases, mobile and servers) I can own a project completely, without pieces getting lost between teams. NB Studio is where I bring all of that experience together for my clients.

How I work

From the first conversation to a system in production.

Six steps, each with something concrete you can see and approve before we move on. No black box, no surprises at the end.

  1. 01

    Discover

    I study your business, your users and what the software must actually do.

    You get a written scope
  2. 02

    Design

    Interfaces and architecture designed together, so the screens and the data model agree.

    You get clickable mockups
  3. 03

    Develop

    Clean, scalable code built in short iterations. You see working software early.

    You get a test version
  4. 04

    Test

    Real devices, real data, edge cases. I break it before your customers can.

    You get a release candidate
  5. 05

    Deploy

    Servers, domains, SSL, stores and data migration handled for you.

    You get a live system
  6. 06

    Support

    Monitoring, updates and new features as your business grows.

    You get one direct contact

One developer, the whole way. The person who analyses your project is the person who writes the code, deploys it and answers when you need a change.

Why NB Studio

Built for you. Maintained by me.

Off-the-shelf software makes you adapt to it. I do the opposite: I learn how you work and build the tool around it.

“Good software isn't the one with the most features. It's the one your team actually uses every day.”

NB STUDIO · WORKING PRINCIPLE

  • 20+ years of experience

    Two decades building real products across web, mobile, desktop and servers.

  • Full-stack & solo

    One developer who owns your project end to end. Nothing gets lost between teams or suppliers.

  • Custom-built, not configured

    Written for your processes, so you don't pay for features you'll never use.

  • High performance

    Clean, optimized and maintainable code built to last and to scale, with no lock-in to proprietary platforms.

  • Client focused

    Direct communication with the person building your product, and solutions tailored to your real needs.

  • Support after launch

    Updates, monitoring, backups and new features. The project doesn't end on delivery day.

  • AI where it saves time

    Used for concrete jobs like reading documents, transcribing audio and automating data entry. Never as decoration.
