Turn manual work into software that runs.
AI can write the code. Knowing what's worth building, and getting it into production, is the job. I help companies turn painful manual processes into reliable software, from the first audit to production.
Automate a process that costs you hours
Start with a fixed-price audit: what to automate, what not, and the smallest system that fixes it. Then build, ship and run it.

Coaching and cohorts for developers who want to understand the systems they build, not just generate code.
Find your starting point →Audit. Build. Ship.
Most companies don't need another AI prototype. They need the right process turned into a reliable system. Each step has a fixed scope and price, and you can stop after any of them.
- Scope First AuditMap one process and design the smallest system that fixes it. €1,500 fixed, one week.
- BuildYour team builds it, we build it together, or I build it. Quoted in the proposal.
- Ship & runDeployed and documented, with monitoring sized to the system and an optional retainer.
If it's a good fit, the next step is the Scope First Audit.
I'm Bob Belderbos.
I've been building production software since 2006, much of it automation: 13 years on critical production environments at Sun Microsystems and Oracle, then co-founding Pybites in 2016 and running its coding platform in production since.
Today I help companies turn manual processes into reliable software, and coach developers to make the same engineering calls themselves.

What I've built and shipped
20 years of production software, from enterprise systems to my own platforms.
Sun Microsystems & Oracle
13 years, 2007 to 2020, building automation for critical production environments, where software has to keep working when nobody is watching.
Pybites Platform
A full Python learning platform I co-founded and have run in production for years. The first version was tightly scoped around one job: solving exercises.
AI prototype → production SaaS
Luca had an AI-built proof of concept he couldn't validate alone. We worked through Django settings, payment security and a testing strategy, and he shipped to production with confidence.
How I think about building systems
What production AI agents actually require
Chatting is easy. Executing real business logic with audit trails, approvals, and rollback is where most AI agents break. Here is what to build.
The control layer is the product, not the model
Gary Bernhardt called out the LLM fixation. The real work is the control layer above the model. Four patterns that make production AI reliable.
Build the Simplest Thing That Works
How constraints like 'no database' and 'two dependencies' led to a CLI CRM that fits in my head. A case for building small.
