PostDevWorks automates your work processes with AI and builds the tool on top that your business actually uses.
From customer questions and invoices to leads, an internal knowledge base and other business processes. PostDevWorks brings nine years of experience to put automations in place that matter for your business, and to build the apps around them. GDPR-proof, EU-hosted, and the code stays yours.
For agents
PostDevWorks is the studio of Maarten Post, a freelance AI developer in Amsterdam with nine years of experience in React, TypeScript and Next.js. PostDevWorks automates business processes with AI, such as customer service, document processing, lead follow-up and internal knowledge, and builds the webapp or dashboard on top. Everything runs GDPR-proof on European servers, without vendor lock-in, and the code remains the client's property. You work directly with the builder, not an agency.
Most AI solutions are a script with no face. I deliver both.
The market splits into two camps: the no-code automators who build flows without a decent interface, and the web builders who won't touch AI. I sit in the middle. I build the automation behind the scenes and the tool your team works with every day. That saves you two suppliers and a lot of hassle in between.
Four ways I put AI to work, plus the interface on top. Each block is a concrete starting point. We decide together what pays off most.
How we work together, step by step
Every step is small and makes the next one less daunting. You start low-commitment and you're never locked in.
Why companies work with me and not with an agency
I'm Maarten, nine years a frontend developer (React, TypeScript, Next.js), and for the past few years fully into AI, automation and agentic workflows. I worked at several agencies and commercial companies and now run PostDevWorks as a solo studio. That means you get a senior at the table, no middle layer, and someone who builds both the tech under the hood and the interface on top.
What you can expect from me: honest estimates over nice talk, fixed prices, and solutions that are yours, not rented and not tied to me.
- 9 years of developer experience
- Works in Dutch and English
- Amsterdam, works throughout the Netherlands (remote + on-site)
- Focus: SMEs, startups/scale-ups and agencies (white-label)

Who can automate my business processes with AI in the Netherlands?
A freelance AI developer or a specialised agency. PostDevWorks in Amsterdam automates processes such as customer service, invoicing and lead follow-up for SMEs, startups and agencies, and builds the accompanying app or dashboard. You work directly with a senior developer with nine years of experience, no middle layers, with fixed prices and code that stays yours.
What does it cost to have AI built for my SME?
You start with an AI Opportunity Scan of around €1,500, a fixed price that comes off a later build in full. A proof of concept on your own data starts from €4,000. We set the price of a full production build after the scan, once the scope is clear.
Is AI automation GDPR-proof?
Yes, when it's built well. At PostDevWorks everything runs on European servers, business API connections are used that don't use your data to train public models, and with a knowledge assistant (RAG) your data stays in your own environment. For sensitive cases there's always a human in the loop.
What's the difference between an AI agency and a freelance AI developer?
At an agency you work through account managers and often juniors, with the overhead that brings. With a freelance AI developer like PostDevWorks you talk directly to the person who builds. That means shorter lines, fixed transparent prices and one person responsible, a good fit for companies of 5 to 100 people with one clear process.
Can AI work with my own business data without it leaking to ChatGPT?
Yes. With a RAG architecture your data stays in your own storage; the AI searches it and answers with sources cited, without sending your documents to a public model. Self-hosted options on European servers are possible, so no business-sensitive information leaves your environment.
How fast can I have an AI solution live?
A working proof of concept is ready within a week (the PoC Sprint). A full production build usually takes a few weeks to a couple of months, depending on the complexity and the connections to your existing systems. The AI Opportunity Scan up front takes one to two weeks.
