Email signature

The block at the end of an email with the sender’s name, role and contact details, often with a logo, added by the mail client or the server.

Most mail clients show a signature as HTML, but each supports a different subset of it: Outlook on Windows renders with the Word engine, Gmail drops some CSS, and many clients hide remote images until the reader allows them. Signatures built from tables with inline styles, with a plain-text version, look the same in more places. For a company the hard part is consistency: one template filled in per person, instead of everyone editing their own.

How I work

“a true bias for action” client CTO, public LinkedIn recommendation

Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).
