Tuinstra.DEV / custom software / discovery

Get the problem clear first. Build software after that.

Tuinstra.DEV helps sport, education, clubs and small teams discover where custom software adds value. If building fits, we build a practical first version.

For workflows that cost too much work by hand, scattered files or recurring frustration.

01 / problem

Many problems need one small tool.

Sometimes it is an intake that keeps getting retyped. A planning flow living in three files. Coaching context spread across chat, Excel and separate documents.

Start with the piece of work that needs a stable home. The app follows from that.

02 / signals

When Tuinstra.DEV can help

Your process works, but costs too much attention.

Information is spread across mails, files and separate tools.

Multiple people need the same context, but each person holds a different view.

You feel software could help, but not yet what should be built.

03 / Discovery

Start small: a workflow discovery.

In a discovery, we map the process, users and friction points. Then you choose: build, do not build, or try something simpler first.

04 / build

If software helps, Tuinstra.DEV can build with you.

Tuinstra.DEV builds small applications that move recurring work out of scattered tools.

Sport and training

Intakes, coach dashboards, workout planning, attendance and tools for boxes, trainers and sports clubs.

Education and learning

Planning, progress, exercises, intake flows and small learning environments for educators, courses and training programs.

Clubs and communities

Members, volunteers, events, communication and simple portals for clubs and local initiatives.

Niche products

Own products and small software ideas where standard tools do not quite fit.

05 / boundary

Bounded work, responsibility included.

Tuinstra.DEV works on bounded problems, discoveries and first versions. I think along about product, users, technology and quality.

Short team work can fit when the work asks for responsibility, choices and quality.

06 / proof

Built from product work.

Tuinstra.DEV is built by Marcel Tuinstra, senior software engineer from Dronten.

On marcel.tuinstra.dev you can find my personal projects, notes and background. Tuinstra.DEV is the business layer: calmer, sharper and focused on practical software.
