Tiago Lelis
Mid Level N3 Support Analyst
Your time is strategic. My mission is to ensure technology runs efficiently, discreetly and reliably with support that anticipates failures and protects your team's performance.
About Me
I am a technical support professional with three years of hands-on experience, currently leading operations in one of the country's largest marketplaces.
Over time, I have developed strong technical skills combined with a user-centered approach, grounded in active listening and a constant focus on delivering solutions that work in the real context of each business.
I stand out especially in complex corporate environments, where seamless integration between platforms, ERPs and hubs requires stability, agility and strategic insight.
I have solid experience with technical and backoffice tools and work closely with stakeholders and managers, acting as a bridge between technology and business goals.
I am currently pursuing a degree in Systems Analysis and Development, which has significantly expanded my technical foundation. The course has provided valuable knowledge in programming, DevOps practices and effective communication between technical and business teams.
If you are looking for someone who listens, understands and solves problems before they reach your team, I am ready to help. Let us make technology your ally for sustainable growth.
