What I believe

01

Beyond features

I don't sell feature-lists — I sell thinking. The design matters more than the result; what's scarce now isn't skill, it's wanting.

02

The AI-agent era

Teams that treat LLM agents as teammates — with skills, memory, and MCP-connected tools — out-ship teams that treat them as autocomplete. I build that way daily: 20+ Claude Code skills, BRD-to-code pipelines, QA automation.

03

Domain over framework

Frameworks change; understanding why a sales pipeline or an ERP flow works is what makes software right. My vertical is CRM and B2B sales — 2.5 years of it.
