Hello! I'm Stefano, a seasoned Backend developer dedicated to simplifying lives through technology. With 6 years of expertise in Java and Node, along with 5 years on Azure and 3 years on AWS, I excel in crafting clean code, solving complex problems on a daily basis.

My proficiency extends to unit testing, event queues, and I bring extensive experience in integrating systems, ensuring smooth and efficient communication between diverse components. Additionally, I have a proven track record of leading teams to successful solutions. Fluent in English, I contribute to dynamic teams and innovative projects.

My goal is to secure a role as a Backend Developer, Tech Lead or Java Developer, leveraging my skills for impactful solutions.

Some achievements:

•Enhanced payment processing for a prominent company by developing a high-impact payment API product, resulting in a significant increase in payment rates.

•Optimized various projects by implementing cache strategies, leading to a remarkable decrease in CPU consumption and response time by over 60%.

•Revamped the approach to writing unit tests for Java Microservices, elevating the quality and efficiency of testing processes.

•Worked at Brazilian Stock Exchange.

More than twenty years of experience in the area of customer service and systems management. Experience in managing and
implementing Information Technology Projects. Ability to interact in different work teams with leadership and flexibility. Excellent technical skill. Excellent management of critical situations and availability to take on challenges. Since 2023, with a focus on learning Artificial Intelligence technology.

Transitioning from building monolithic applications for small / mid-sized companies was not easy. I had to spend almost a year on mapping and catching up with the tech stack that the industry was requiring and adapt to the microservices / distributed systems paradigm.

After working for more than a year for a large sized tech company, I shifted my goals. In the long term, I wish to qualify myself as a modern web platform architect in order to create highly available environments with development patterns that would be logical for the teams to adopt.

In the short term perspective, I’d still have a long way to go, working as a full stack web developer to acquire the necessary knowledge in order to continue on my journey.

As for the types of business, I have interest in well established companies that works with multiple teams and mature agile management. However, I’m also fond of small / mid-sized start-ups where we may contribute in different areas and help build our own process – very exciting.

I’m in search of an opportunity where I’d be part of a multidisciplined team, learn from each other, produce great work that we can be proud of and still have fun on the way!
