At StackSpot I'm part of a multidisciplinary team responsible for developing an AI-driven modernization platform using concepts such as RAG, Gen-AI, code conversion, etc. Our mission is to develop the best tool for legacy code modernization using AI features.

Astronomy is an educational app, that provides users an exciting experience to expand their knowledge about our cosmos.- Successfully deployed open, internal, and production releases to the Play Store using CI/CD pipelines with GitHub Actions and reached over 1000 access.- The decision to use a multi-package (mono-repo) application brought extreme flexibility and good organization to the whole app architecture.- A data-driven app using observability concepts to analyze and provide a better experience to the users with bug-free releases, using Crashlytics and Google Analytics tools.- Implemented cloud test, and distributed databases with Firebase and Mongo DB.- I've been coding with TDD, JUnit, Mockk, and Mocktail, reaching a coverage rate of 70%.App Link: https://play.google.com/store/apps/details?id=com.will.astronomy.app

At "Novas Parcerias" squad I was responsible for creating an application, from visual conception to code implementation. The objective was to increase traffic to the partnership product, using SEO optimization strategies. Additionally, I developed a chatbot employing LLM models (StackSpot AI), applying concepts of Prompt Engineering and RAG (Retrieval Augmented Generation).- Implementation of a chatbot focused on integration with LLM agents, using TypeScript, RAG, and StackSpot AI.- Implementation of backend services using Kotlin, SpringBoot, AWS, and Terraform (Infrastructure as Code).- Utilization of StackSpot EDP for repository and plugin configurations, achieving 42.86% more efficiency than non-utilization.

At "Itaú Sign" squad I contributed significantly to the development of an electronic signature platform that enables the sharing of resources between internal products, mainly using Android and Angular to integrate the product with inner journeys into the super app. My achievements include:- Collaborated with cross-functional squads with different approaches, helped others to integrate with our product, and scaled the application up to 500,000 users.- Implemented clean architecture approach and other best coding practices in our codebase. Mainly using micro-frontends, web-view, android with Kotlin, reactive programming, and design systems.- Data security and user experience are very important aspects of our product. I had the opportunity to implement strategies to ensure the application's security, such as reverse proxy concepts.- Conducted an extensive analysis of the production release using concepts of observability and tools, such as Google Analytics and App Dynamics, to engage and track possible issues that could impact our users.

As a software engineer at BNP Paribas - Cardif, I was tasked with developing a mobile version of the web platform using Flutter. The product was a dashboard that enabled users to claim their insurance protection. We performed a thorough analysis using data metrics from Google Analytics and then migrated our legacy Angular web app codebase to the mobile version. Some of my accomplishments include:- Collaborating closely with the product team and stakeholders to develop new features and scale the app to over 4000 users to the MVP release.- Continuous improvement of the development process focusing on best practices, such as CI pipeline for code quality, and code review agendas, also I had the opportunity to guide new members.- Prioritizing data security and user experience by implementing encryption using Flutter Secure Storage and authentication.- Usage of observability concepts and data metrics with Google Analytics.

I was responsible for developing a web dashboard to supply a new product of the company, the POS (point of sale) for card machines, the frontend application was built with Angular and consumption of BFF APIs (NodeJs). Some of my accomplishments include:- Development of new features, mainly using design system components, reactive paradigm with RxJs, and state management using Redux (NgRx).- Implemented UI documentation using Storybook to provide a better developer experience for the internal teams.- Collaborated with the mobile team to share resources and improve the user experience of the overall platform.

I've worked as a full-stack engineer as a member of an innovation squad, responsible for developing an ERP (Enterprise Resource Planning) for many companies. The frontend was built with Angular and the backend in PHP (Symphony framework) also worked with micro-services architecture and AWS infrastructure.Some responsibilities and technologies: - I was responsible for bringing more flexibility to the overall performance and developer experience of the frontend application using concepts of state management with Redux (NgRx)- Engage with the product team to develop a user-centered application for MVP release of the app.- Contributed to the production analysis using AWS cloud watch, Google Analytics, and Grafana.

I had experienced teaching database I and II disciplines when I was studying in college, with the following approaches:- Data modeling for database structures- Normalization- Relational Algebra- DDL and DML
