Maintenance & Support Stabilising an inherited Laravel platform nobody dared to restart

A half-finished Typo3-to-Laravel migration, a 15 GB repository and a production server nobody dared to reboot. Audit first — then backups, security fixes, Docker and ~500 tests.

Modernisation & Upgrades MySQL upgrade that cut about $10k a year in AWS costs

An outdated MySQL 5.7 database was quietly adding about $900 a month in AWS Extended Support fees. We planned and ran a safe upgrade to 8.0 around a live legacy application.

SAP–Shopify sync rebuilt from legacy PHP to Symfony

Keeping a Symfony 1 / PHP 5.4 website safely in business

Maintenance & Support Keeping a Symfony 1 / PHP 5.4 website safely in business

A property website on Symfony 1 and PHP 5.4 still earned its keep. We maintain it carefully — SEO updates, feeds, cache issues — and brought production changes back under Git control.

The outage that wasn’t the application: a Route 53 DNS story

Rescue & Incident Response The outage that wasn’t the application: a Route 53 DNS story

Internal business systems stopped resolving even though the servers were healthy. We traced the outage layer by layer to incomplete Route 53 delegation and restored access.
