Wojciech Płonka and I run Programo, a software house in Poznań. We build websites, stores, systems and mobile apps for companies, and our own products on the side, including Estalo, a CRM for real estate agencies.

At Programo I run engineering. We have no salespeople and no subcontractors, so from the first call to maintenance the client talks to the person writing their code.

Programo

A two-person partnership in Poznań. Wojciech leads design and product, I lead engineering. We build, deploy and maintain everything ourselves.
