Custom software for work that falls between tools.

Workflow discovery

You map the process before you put budget into code. That makes choices about scope, priority and technology easier.

• Process and friction points
• Stakeholders
• Build/no-build advice
• First-version scope

First version build

Tuinstra.DEV builds small applications that support one workflow well. Think intake, planning, progress, reporting or handoff between parties.

Sport and training

For boxes, trainers and sports clubs: intakes, coach dashboards, workout planning, attendance and connections to tools you use today.

Education and learning

For educators, courses and training programs: planning, progress, assignments, intake flows and small learning environments.

Clubs and communities

For clubs and local initiatives: members, volunteers, events, communication and portals that create overview without extra admin load.

Short team work

I can join a team for a short period when the work asks for product thinking, quality and decisions. Lists of loose tickets fit less well.
