What I'm looking for

I’m interested in projects involving scalable platforms, the gaming industry, test automation, platform design, consulting, and leading or managing programming teams. I also value personal development, good development practices, and thoughtful project construction.

At zinc.tech, I delivered a test automation ecosystem after assessing an existing project and defining a technical roadmap. It included data-driven and end-to-end testing tracks, AI agents configured for testing and development tasks, and a dashboard for running tests and monitoring results.

At Gorilla Logic, I contributed across client projects and internal initiatives. For Trisept Solutions, I developed Angular components and backend modules for a travel plan acquisition system, integrated third-party services, and implemented tests.

At Cigo Tracker, I built components and modules for an Angular-based package delivery management platform, including planning, tracking, and real-time notification features. Earlier, at VCB S.A.S., I developed public-sector and enterprise platforms and integrated AI assistants into Moodle-based learning platforms.

Through my freelance work at 16 Ball Creations, I have developed web applications and custom platforms, alongside graphic design and YouTube channel production. I’m interested in automation testing, platform design, gaming, and opportunities to lead teams and contribute to projects with long-term potential.
