Independent by design
Behind Streng Labs is Sebastian Streng, a full-stack developer focused on software architecture, with a B.Eng. in Software Engineering. He has been building software professionally since 2019, in automotive, enterprise and industrial projects: from modernising platforms with several hundred thousand users to taking over and stabilising existing systems.
Streng Labs is a sole proprietorship. It decides itself which products it builds and which client projects it takes on.
For clients this means direct contact: the person who discusses your project also designs and writes the software. There are no sales layers and no hand-offs to subcontractors you have not agreed to.
Own products and client work
Streng Labs builds its own products and takes on selected client projects. Building software for its own users means dealing with the whole life cycle: accounts and payments, support, privacy, updates and preparing store releases.
Client projects benefit from that experience: decisions are made with operation in mind, not just the first release. What we build for clients

- Typed code, automated tests and documented architecture decisions.

- Plain communication about scope, progress and problems.
