I will build an ai agent for your process, or plain code when that is better
Jakub Z.
About this gig
I build AI agents and automations that keep running after I hand them over.
Not every problem needs an AI agent. Where the rules are fixed, plain code is cheaper, faster and does the same thing every time - I will tell you when that is the better answer instead of selling you a model. AI earns its place where the input is messy: free text, documents, decisions no rule table covers.
The other half is what happens later. Most automation breaks quietly a few weeks in: an API changes, a token expires, a rate limit hits, and nobody notices until someone asks why the reports stopped. Eighteen years in enterprise IT infrastructure taught me to build for the failure cases first.
What I have built for clients:
- an agent that files incoming email from a public authority by document type
- - invoice data extracted into a spreadsheet, no manual retyping
- - web form submissions routed straight into a CRM
Tools: n8n, Python, LLM APIs (Claude, OpenAI), REST and webhooks, Linux servers.
I work remotely from Prague, hold CCNA and PRINCE2, and lead an infrastructure team.
Tell me the process you want gone. I will tell you if it is worth automating.

I build AI agents and automations that run in real production, not in demos. 18 years in enterprise IT infrastructure, and I lead an infrastructure team - that is the difference between an agent that still works in a year and one you delete after two months. I build email triage agents, invoice and receipt processing into your spreadsheet or CRM, document classification, RAG search over your own documents, and lead automation. Also websites and web apps. Stack: Claude API, OpenAI, Python, REST APIs, vector DBs, OCR, Docker. Running solution in about two weeks, then handover and training.

FAQ
Do I need an AI agent, or would plain code do?
Often plain code. If the rules are fixed, deterministic code is cheaper to run, faster and behaves the same every time. Describe the process before ordering and I will tell you which one you need, even when the answer is the cheaper one.
Will this keep working without me maintaining it?
That is what the Production Agent package is for: monitoring and alerts, so you find out from the system rather than from a customer. Most automation breaks quietly weeks later, and silence is not the same as success.
Do you work with the tools I already have?
Yes. I fit into your stack rather than asking you to move: n8n, Python, LLM APIs, REST and webhooks, Linux servers. If something in your setup makes the job harder, I will say so before you order, not after.
