Ignacio Carreño

Hi_

I am a senior full-stack developer and systems engineer with over 17 years of experience turning complex product needs into reliable, scalable web applications.

Over the years, I have grown from building and fixing features end to end into owning architecture, improving delivery pipelines, modernizing platforms, and supporting other engineers through technical guidance and team-oriented leadership. Alongside that work, I continue to cultivate my passion for teaching software engineering at UCC.

I bring deep experience with PHP, JavaScript, Node.js, Python, DevOps, QA automation, and cloud-adjacent workflows, while keeping the practical mindset I have always valued: fixing what is broken, adapting what needs to change, and choosing the simplest strong solution.

I believe that clear communication, timing, creativity, and ownership are the foundations for teams that consistently deliver outstanding work.
