Building across silicon, steel & systems.

(01) Who Joaquin Herman — software, hardware, mechanical and AI-native. Based in the Netherlands. Currently in business at a sustainability firm and a real estate brokerage. Building tools, shipping workflows, learning fast.

(02) — Working principles

(03) — Four stacks Still learning all of them
i
The software stack.
Full-stack web, internal tools, scripts. The layer most people actually see. Dashboards and workflows — usually TypeScript, Python, or whatever the team already lives in.
TypeScript React Python Postgres Vercel
ii
The hardware stack.
PCBs, microcontrollers, embedded. The bridge between the code and the thing it controls. Custom boards, soldering, firmware in C or MicroPython. Still figuring out how much of this I can do without burning the workshop down.

iii
The mechanical stack.
CAD, fabrication, brackets that hold. The layer with weight. Parametric modelling, 3D printing, light CNC work. My least-polished domain — which means everything is still a lesson.

iv
The AI layer.
Claude, MCP, agents, prompt design. The layer that now runs through all three others. Deep in Anthropic's ecosystem — Claude Code, the API, MCP, agent skills, subagents — certified across fluency, agents, and the protocol itself.

A running log of where the hours went — Anthropic, Coursera, IBM, Vanderbilt, Sololearn. Heavy on AI fluency, agents, MCP, and the Claude ecosystem. Continuously updated.

(06) — About Almost full-stack

A beginner engineer — sincerely — working across software, hardware, mechanical and AI. Based in the Netherlands. Currently in business at a sustainability firm (solar, storage, heat pumps) and a real estate brokerage, where I ship internal tools and AI workflows. Happiest when one project spans several disciplines, and the only way forward is to read another datasheet.
