Our responsibilities include managing distributed cache, script engine, MongoDB and Elasticsearch databases, and clustering functionality using Hazelcast.I conduct individual follow-ups with team members, which has significantly improved our development processes. We have introduced practices such as the use of Architecture Decision Records (ADRs), a book club, and a strong code review culture.Our team is also responsible for keeping our technologies up-to-date. Recently, we upgraded the platform to Java 21 (GraalVM) and Elasticsearch 8, organizing and managing the necessary migrations to deliver these updates efficiently. Show less

In my work on the backend of the SYDLE ONE platform, I conducted performance improvements, optimizing access and write flows in the databases, which resulted in significant cost reductions.I worked in developing new functionalities for one of the company's main products, SYDLE Analytics. This allowed the extraction of comprehensive reports with real-time information from SYDLE ONE, enhancing the product's value to clients.I also led experiments to evaluate the best alternative… Show more In my work on the backend of the SYDLE ONE platform, I conducted performance improvements, optimizing access and write flows in the databases, which resulted in significant cost reductions.I worked in developing new functionalities for one of the company's main products, SYDLE Analytics. This allowed the extraction of comprehensive reports with real-time information from SYDLE ONE, enhancing the product's value to clients.I also led experiments to evaluate the best alternative for replacing the script engine used in SYDLE ONE. I collected and analyzed data to support the decision-making process for selecting the optimal solution. The implementation of this new script engine facilitated the successful delivery of projects for SYDLE.To ensure the efficiency of the developed solutions, I implemented performance tests. My technical toolkit during this period included Java, JavaScript, K6, JUnit, MongoDB, Elasticsearch, Hazelcast, Rhino, and GraalVM. I consistently applied agile methodologies to streamline development processes. Show less

I worked as a researcher focusing on a classic optimization problem known as the Minimum Latency Problem. During this period, I developed algorithms for this problem using Branch and Bound and CPLEX, and implemented solutions in C++. I also published and presented a scientific paper at the Brazilian Symposium of Operations Research.
