What I build
Four services, each one backed by code running in production.
Custom MCP Servers
I connect Claude or any AI agent to your billing, CRM and internal APIs.
See finetwork-mcp →Agents for Business Workflows
I build agents that take a whole process off your plate, like invoicing, bank feeds or reporting.
Read the case study →Business Automations
I turn your manual back-office work into pipelines that run unattended every night.
See the platform →Technical Writing
I write the tutorials and docs that get developers using your product.
Read my articles →Work with me if...
- You pay for ChatGPT or Claude, and nobody in the team knows what to actually do with it.
- You tried a chatbot on your docs and it made things up in front of a customer.
- Invoices, orders and forms arrive as PDFs, and someone retypes them into your system every day.
- You answer the same emails with the same words every week, by hand.
- You want AI working on your company data, and sending it to a public cloud is not an option.
If one of these sounds familiar, that is the work I do. Tell me about it →
