## Company

- [Home](https://jazzy.pro/): who we are, what we do, selected work
- Seweryn Zeman (Seth), Business to product: Turns business needs into working products, from architectural scope to final delivery. From thousands of IoT sensors to fintech software.
- Robert Łabuś (Atom), Integrations & real-time: Untangles any integration problem you throw at them. Thousands of real-time betting transactions for half a continent, a sales pipeline rebuilt for a national market leader, audio waves, analysed.
- Sławomir Pruchnik (Slawek), Live & streaming: Keeps heavy real-time systems calm when thousands are watching. Augmented live streaming for hundreds of thousands of viewers, or just a few.

## What we do

- Build your product: From first workshop to production and beyond. A business need goes in, working software comes out.
- Be your fractional CTO: We set the technical direction, build and coach your team, and take responsibility for delivery, without a full-time hire.
- Modernise your legacy system: We replace the old platform in stages, without pausing the business.
- Connect and run it in real time: Payments, streaming, betting or IoT sensors and the integrations between them.
- Put AI to work: Assistants and agents that answer from your own documents and automate real workflows.
- Audit your technology: A senior review of your architecture, code and risks, with clear next steps.
