William Caldwell

Expert in Linux & Free Software, I am a Systems, Network & Security Engineer by training, and have held various roles in my career:

- Development in functional languages (OCaml, Clojure, Guile)

- C development in the Linux kernel on embedded platforms

- Website deployment (DevOps, CI/CD, security: secret management, firewall, application security)

- Project & team management with agile methodology

In System Administration/DevOps: I can help you deploy open-source solutions, perform system administration (servers & user workstations), troubleshoot faulty systems, and secure services.

In Software Publishing, I can help you architect a system and code it in the language of your choice (I would recommend a functional language for the quality & robustness it provides).

In Data Processing, I can do scraping & cleaning/formatting.

On my website, I share my adventures in IT (and climbing); it is developed in OCaml with the Ocsigen stack & a PostgreSQL database and deployed with Guix.
