dthas is a one-person software studio delivering tailored software and consultancy. Small by design: direct access to the person building the work, with the rigour of a much larger team.
The name stands for design · technology hub and services, and for the founder's initials. Engagements run end to end: architecture, back end, front end and deployment, or a focused slice of any of them. Clients range from early-stage products to established teams that need senior capacity without the headcount.
Work is judged by what runs in production, not by what is promised in a deck. Much of it ships under NDA; the discretion is part of the service.

Engineering-led, understated, in production.
A short set of principles that hold across every engagement.
Development first
Engineering leads every engagement. Design and consultancy strengthen the build. They never stand in for it.
Direct access
You work with the person writing the code. No account layer, no hand-off, no telephone game between brief and build.
Pragmatic by default
The stack fits the problem, not a trend. The right tool is the one that ships, scales and stays maintainable.
Confidential by default
Most work ships under NDA. Clients are described by domain, never by name. Discretion is part of the service.
