In-house product

Data-driven prospecting CRM with agentic AI workflows

Software architect, product owner, full-stack developer

Design and incremental development of my own application for researching, assessing and managing sales activities. At its heart is an agentic human-in-the-loop workflow: a validated intake turns unstructured input into checked business data, and existing systems connect through custom MCP servers. A working example of how AI capabilities are integrated into an architecture in a controlled and traceable way.
