Summary about my trajectory

My journey in the field of Information Technology began at 16, in 2011, at a local tech support known as "Cosmic" near home. In this environment, I gained practical experience by assisting customers and performing maintenance on computers, laptops, tablets, configuring home networks, and supporting mobile devices, building a solid foundation of technical knowledge from an early age.

After finishing high school and starting my degree in Computer Networks, more challenging opportunities arose, leading me to an internship at Tivit, a renowned technology solutions and BPO services company. I worked directly in the BPO tower for about 1.7 years, providing HelpDesk support to the internal client. My responsibilities included hardware, software, telephony, network support, and communication infrastructure. Working in a large company with access to high-availability data centers and cutting-edge technologies improved my technical skills and provided valuable analytical perspectives.

Later, I was hired by Sumus Informática, specializing in asset management software focused on corporate and mobile telephony. My career evolved significantly, beginning as N1 technical support. I worked with databases like Firebird, SQL Server, PostgreSQL, and MySQL, progressing from junior to senior. At the company, I became a technical reference, expanding to technical coordination, training, implementation, and senior consultancy roles.

At Sumus, I developed advanced skills in Linux, server administration, web applications, and telephony system integration, including developing drivers for PABX billing. Besides producing technical content, such as videos, manuals, and training, I led implementation and training projects for various clients across Brazil.

With the increase in cloud-based models, I decided to deepen my knowledge in cloud infrastructure. I was hired by Mtrix tecnologia, now part of NielsenIQ (NIQ), as a Junior Cloud Analyst and embarked on certification journeys in cloud computing, pursued postgraduate studies in cloud services and systems engineering, and obtained AWS specialist training, successfully achieving certifications in Azure, GCP, and AWS. My role evolved to a mid-level position due to the knowledge acquired and relevant technical deliveries, making me responsible for cloud service migrations, Microsoft 365 tenant administration, user management in hybrid environments, and much more. Currently, I am the right hand of my tech lead in IT Operations, mapping improvements, proposing solutions, managing incidents, and acting as a facilitator between technical and business areas.

At Mtrix, I delivered significant projects in documentation, automation, monitoring, and observability. I developed data pipelines and ETL processes that feed semantic data models and dashboard interfaces, helping various squads gain insights based on numbers, generating important alerts based on metrics, thus bringing visibility, awards, bonuses, promotions, and extremely positive feedback from the company's board and presidency. This recognition reflects my commitment to excellence and results focus.

I am driven by solving complex problems, automating processes, and transforming data into valuable insights for decision making. I believe that with my commitment, clarity, and efficiency, I can significantly contribute to any team.
