About Geert
I'm specialized in solving big problems quickly. Automating tedious tasks from taking days or weeks to a few minutes or seconds. Making a lot of systems talk to each other and pass data around (ETL).
I'm obsessed with making things run smoothly. Speeding up API's, apps and websites top to bottom by automating and splitting up tasks and processes.
My work is very transparent, putting all I do in Git and making system configurations reusable and easily manageable via IaC (using Terraform) and putting everything in Ansible playbooks. On top of this, if budget is available, I can write extensive docs in English and/or Dutch.
My prefered tools are:
Terraform, Ansible, AWX, Debian/Ubuntu, Docker, PHP, MariaDB/MySQL/Galera, Elasticsearch, Memcached, Redis, RabbitMQ, Symfony, Tailwind, Node, Python, Golang, Gitlab, Prometheus/Grafana, Zabbix, N8N, Claude, AWS, Hetzner, Cloudflare, Bunny.net and a lot of performance and testing tools.
But anything is possible, you can always ask for an estimate.
