What I'm looking for

I’m seeking Engineering Manager, Technical Lead, Senior Software Engineer, Software Architecture, or Platform Engineering roles, especially with organizations focused on SaaS, cloud-native applications, enterprise systems, platform scalability, and high-impact product development using PHP and JavaScript.

At ACTO, I established process and coding standards across multiple web teams, improving DORA metrics and helping teams deliver efficiently. I also mentored team members and worked with product and project managers to align technical roadmaps with business objectives.

Earlier at Cast Group, I developed the digiSUS national health planning system for the Ministry of Health using Laravel, PHP, and Oracle. The platform gave health secretaries dashboards and reports as county data was submitted, replacing a reporting process that had taken more than six months.
