Gonzalo Osuna
@gonzaloosuna
IT support and junior Java developer trainee pursuing a first IT role, with hands-on PC repair experience.
ArgentinaWhat I'm looking for
My PC and laptop repair work for private clients taught me to diagnose faults by testing possible causes one by one, using forums and manuals to investigate unfamiliar problems. I also handled operating system installations and hardware maintenance.
At Farmacias Sánchez Antoniolli, I used Plex 25 and health insurance validators in my pharmacy assistant and customer service role. I corrected authorization errors, responded to system issues, and coordinated with the systems manager when needed.
I'm deepening my Java skills through Udemy, YouTube, and documentation, building on training in Java, JavaScript, React, and Node.js. I'm seeking my first opportunity in IT in backend development, technical support, or systems back office, where I can learn and contribute.
