Integrate any ATS, CRM, or sourcing tool with AI.
I’m Michal Juhas. I build custom AI integrations for recruiting and revenue teams, connecting the tools you already use to Claude and to each other, then handing off a system your team owns. It’s execution inside your workflow, not another dashboard.

How it works
Built for recruiting agencies.
From idea to a system you own, connecting your ATS, CRM, sourcing, and enrichment tools with Claude doing the work in between.
- Step 1
Describe the outcome
Tell me the result your agency needs, like a ranked sourcing shortlist or cleaner client reporting, and the tools in your stack. First reply within two business days.
- Step 2
Scope & connect
We confirm the scope, then I wire your stack together via their APIs: your ATS (Ashby, Greenhouse), CRM, sourcing tools, and enrichment like Coresignal, ContactOut, or Hunter.
- Step 3
Build
I build the workflow with Claude doing the heavy lifting: parsing profiles, enriching candidates, ranking shortlists, and drafting outreach, with regular check-ins.
- Step 4
Handoff
Live walkthrough, a recorded Loom, and a written runbook. Your agency owns the system and the data.
What I integrate
Your stack, connected to AI.
If it has an API, it can be wired into a workflow. A condensed view of the tools I work with most.

We build using CalyflowOS
A faster start means a lower bill.
Your build is delivered on CalyflowOS, the applied-AI operating system I built for custom client work. Because the foundation is already there, I start new projects faster and with less effort, and that efficiency is passed on to you as a lower cost.
- A head start on every project, so you pay for outcomes, not boilerplate.
- Proven building blocks for connectors, enrichment, ranking, and reporting.
- Runs in your own environment, with full visibility into every run.
Pricing
Simple, transparent pricing.
A fixed starting price for the build, hourly for anything after, and optional hosting if you’d rather not run it yourself.
Custom build
From €2,000
per project
We agree on what's in scope, then I build it. A custom build project starts at €2,000. No pre-payment, you only pay after the first milestone is reached.
Ongoing support
€150
per hour
Need to build something else, or customize an existing automation? AI implementation and agentic engineering support, billed hourly.
Managed hosting
€100–€300
per month
Optional: I host the solution in my Google Cloud project so you skip the technical setup. Priced by how many tools and systems run, excluding AI tokens.
