D2R (short for DEV2REV) is a one-person studio that combines consultancy with a focused product line. I build custom software for teams with real operational complexity, and develop my own SaaS tools in niches I know well.
When a project calls for more hands, I bring in trusted developers for the specific module — same stack, same standard, same accountability. No B-team handoffs, no endless discovery phases.

Teams of 2 to 50 people with a workflow that generic software almost fits, but not quite. The sweet spot is operational software that needs to match how the business actually runs.
