With 15+ years in software engineering and MarTech, including leading engineering for European SaaS products, I now help businesses build and automate their GTM systems. ✅ Workflow Automation: Automate repetitive sales, marketing, and RevOps processes with n8n, APIs, and custom code. ✅ CRM Integrations: Connect HubSpot, Salesforce, websites, marketing tools, and internal systems — with reliable data sync and clean field mapping. ✅ Data Enrichment & GTM Workflows: Build enrichment, lead scoring, routing, outbound, and AI-powered workflows using tools like Clay and n8n. ✅ Attribution & Revenue Data: Connect acquisition sources, leads, deals, and revenue so teams can see what actually drives results. I combine hands-on engineering with a business-first approach: understand the funnel and process first, then automate the parts that create measurable value. From a simple CRM integration to a custom revenue data pipeline, I can handle the full workflow — requirements → architecture → APIs → automation → QA → handoff. Need to connect your GTM stack or automate a messy manual workflow? Let’s talk.

This is the second time we use Keepitok and they delivered what needed to be done, in budget, in time. They didn't apply some "blanket recipe" to the project and tried to understand what we really needed and do the right thing to make this project successful. They didn't hesitate to challenge us on some of our assumptions, which is always appreciated. I would use them again and would recommend them.
