Full Stack EngineerTopdown Sistemas Jul 2020 - PresentRio De Janeiro, Brasil- After spending a few months away from the company to explore other opportunities, I was invited back by my former coordinator in recognition of my contributions to both the team and the company. During that time, I had the chance to address significant challenges. I implemented a new recurring payment method for beneficiaries with health plans. Similar to a subscription, this method involved integrating with a payment gateway to handle automatic and retrying charges. This innovation attracted more clients by allowing recurring payments without impacting the credit limits of the beneficiaries.- Additionally, I developed an application to update our system's database with information on medical professionals, in compliance with the Federal Council of Medicine (CFM). With a database containing over 500,000 registered professionals, this efficient application updates the system’s data within minutes.- C# · .NET Core · Microsoft Azure · Oracle · PL/SQL · SQL · Git · GitHub · JavaScript · jQuery · ASP · Scrum · Java · Representational State Transfer (REST) · JSON Web Token (JWT) · RabbitMQ · Web Services · Dapper (ORM)

In this role, I designed and implemented a scheduled process to automatically deactivate router subscriptions upon expiration. This daily process efficiently deactivates thousands of expired subscriptions and notifies clients via email, ensuring smooth operations while minimizing computational resource usage.- Additionally, I am actively working with the architecture team to refactor and optimize our codebase. These improvements have significantly enhanced system performance and scalability while reducing costs, resulting in monthly savings of $10,000.- Node.js · MongoDB · MySQL · Elasticsearch · Redis · Docker · Continuous Integration (CI) · Continuous Delivery (CD) · Sonarqube · Amazon Web Services · Amazon EC2 · AWS Elastic Beanstalk · Linux · PHP · JSON Web Token (JWT) · Git · GitHub · PostgreSQL · Scrum -
Software EngineerSoftwrap Jan 2022 - Aug 2022- I worked on developing a mobile platform that allows users to organize their favorite TV series, discuss seasons and episodes, and rate them. These ratings help other users discover highly-rated series to watch. The entire platform is updated daily through an application that reads from TMDB, a database with over 500,000 pieces of content, including movies and TV series. Every day, the platform checks for updated series in the TMDB database and updates its database accordingly.- Node.js · NoSQL · MongoDB · React.js · React Native · GraphQL · Apollo GraphQL · Jest · Figma · Docker · JSON Web Token (JWT) · Git · GitHub · Scrum · Apollo -
Full Stack EngineerReserva May 2019 - Jul 2020Rio De Janeiro, Brasil- At the company, I created, deployed, and trained staff on a new version of the WMS system, which processes thousands of orders daily. This upgrade significantly enhanced the efficiency of the distribution center, allowing for an increased volume of orders. The management of product flow—through entry, maintenance, and exit—became more streamlined and effective, boosting overall performance.- Additionally, I contributed to developing an affiliate platform that attracted numerous affiliates, leading to a substantial increase in company sales.- C# · .NET Core · SQL Server Management Studio · SQL · Angular · TypeScript · Bootstrap · jQuery · Git · API REST · Representational State Transfer (REST) · JSON Web Token (JWT) · Web Services · JIRA · PL/SQL · HTML5 · Microsoft SQL Server · HTML · Scrum · JavaScript -
Full Stack EngineerTop Down Sistemas May 2013 - May 2019- I was responsible for maintaining and developing new features for the health insurance brokers' commission module. One key feature I implemented was a sales campaign tool that rewarded brokers for selling health insurance plans. Each campaign had specific rules, along with defined start and end dates. This feature successfully engaged thousands of brokers and attracted new customers monthly, yielding significant returns for the company.- Additionally, I resolved a critical issue that caused the company to lose thousands due to incorrect commission calculations. After correcting the error, I created scripts to reverse all erroneous payments made to the brokers.- .NET Core · MVC Architecture · VBScript · SQL · SOAP · jQuery · IIS · VBA (Visual Basic for Applications) · C# · Oracle · Representational State Transfer (REST) · Visual Basic · Git · Visual Basic .NET · Web Services · GitHub · PL/SQL · Dapper (ORM) · ASP.NET MVC · Scrum · Jasper Reports · JavaScript

Full Stack EngineerTarea Management Mar 2012 - May 2013Rio De Janeiro Area, Brazil- The Maracanã stadium underwent an expansion renovation, adding "captives" (reserved) seats for owners to watch shows or games without buying tickets. To manage the existing owners of these seats, I designed a system to draw lots for nearly 5,000 out of over 78,000 seats.- Additionally, I worked on constructing the Content Management System for the website providing information about the Rio+20 event, which took place in the state of Rio de Janeiro in 2012.

Software EngineerB2W Digital Mar 2011 - Mar 2012Rio De Janeiro Area, Brazil- I have worked on integrating invoices with SEFAZ (Department of Finance). I developed a new feature for importing invoices using a positional structure, which replaces the previous approach of importing CSV files, where data was read line by line and column by column. With the new approach, data is now read from a single line, with each field parsed according to its specific length as defined in the database schema. This change reduced the import time from 15 minutes to 2 minutes. -

It HelpdeskEstácio Feb 2009 - Feb 2010Rio De Janeiro, BrasilI helped company employees with phone support and remote computer access. While still early in college, I noticed frequent occurrences during one work shift that needed to be relayed to the next. To address this, I had the idea to create an alert system for the department.
