What I do
Three ways I can help.
-
This one
Process automation
Turn a manual process into software that runs.
Orders retyped across systems, month-end reconciled by hand, the spreadsheet only one person understands. I map the process, decide what's worth automating, and build the smallest reliable system that fixes it.
Talk it through →- Your team enters data once, not in five places
- Plain, tested code for most steps, AI only where the input is fuzzy
- Deployed, documented and yours to keep
-
This one
AI adoption
Get AI into real work, where it helps.
You have licences, a pilot or a board asking about AI, but nobody has defined what it should do. We pick the workflows where it pays off, put validation and human sign-off around it, and teach your people to use it with judgment.
Talk it through →- A clear view of where AI helps, and where plain code is better
- One real workflow in production, not another demo
- A team that can review and steer what AI produces

This one
Fractional CTO
Technical leadership, part-time.
Someone to help decide what to build, which technologies to use, and how to get the most from your developers or agency. Hands-on, alongside your team, for a specific challenge or as an ongoing role. I spent 13 years in critical production environments at Sun and Oracle, have decided what to build and which technology to use as co-founder of Pybites since 2016, and have coached 150+ developers. You get that judgment, part-time.
Talk it through →- Technology strategy and a roadmap tied to business priorities
- Architecture, build-vs-buy and vendor decisions
- Technical direction and review for your developers or external agency
How it works
It starts with a call.
Everything is custom, so there's no menu to pick from. Bring the problem, not a spec.
-
1
A call
We talk through what's costing you time or what you need to decide. If a spreadsheet or your current tools are enough, I'll tell you.

2
A written proposal
Scope, timeline and a fixed price, shaped to your situation. If the problem needs mapping first, that becomes the first step.

The work
Your team builds it, we build it together, or I build it. Tests, monitoring and docs are part of the job, you own the code, and an optional retainer covers what comes next.
Proof
Not a demo. I run my own books on it.
Replacing my paid bookkeeping tool
The result: no more subscription. Closing the month is one step, my accountant can trace every figure back to its source, invoices can't be overwritten, and the data is mine.
Sun Microsystems & Oracle
13 years in critical production environments, around eight of them focused on support automation.
Pybites platforms
Python and Rust coding platforms I designed and built, in production for years.
Questions
Before you book
What happens on the call?
We talk through your situation: what costs your team time, or what you need to decide. No spec needed. Then I tell you what I see and what the next step would be.
What will it cost?
It depends on the work, so it's scoped after the call. You get a fixed price in writing before you commit to anything.
Do we need to use AI?
No. Most of a reliable business system is ordinary code, rules and tests. AI goes where it improves the outcome.
Who owns the code?
You do. All code and infrastructure built during the engagement belongs to your company.
Do we need our own developers?
No. If you have developers, I work with them and they keep the knowledge. If you don't, I build it for you.
I'm Bob Belderbos.
I started in finance, automating reports at CHEP, then spent 13 years at Sun Microsystems and Oracle, around eight of them on support automation. So I understand the business process as well as the system behind it.
I've also coached 150+ developers through thousands of code reviews, which taught me to spot design problems early and to transfer ownership instead of creating dependency.
