I'm André Barros

In July, I officially registered my business to pursue an independent career and expand my work as a developer. This new chapter allows me to take on projects autonomously, collaborate with different partners, and continue building software solutions.

At Pravaler, I worked across multiple strategic products involving frontend development, platform modernization, system integrations, and infrastructure tooling. I initially maintained and enhanced an internal employability platform built with Vue.js and Nuxt.js. I later contributed to a whitelabel scholarship platform developed for enterprise partners such as iFood, enabling employees to access higher education. I then became responsible for a customer service platform, leading a full UI/UX redesign, implementing new Figma-based interfaces, and migrating the application from React to Next.js. The platform used Redux, Storybook, React Testing Library, and a complete CI/CD pipeline. Beyond frontend work, I supported backend development using Node.js and NestJS and worked on integrations with CRM systems like Zendesk and Salesforce. I also participated in automation, infrastructure, and monitoring processes using Backstage (repo templates), ArgoCD (pod/log monitoring), Grafana (metrics and alerts), New Relic (SSR monitoring), and Terraform for service provisioning. Toward the end of my tenure, I contributed to improving student onboarding workflows—registration and enrollment visibility—using Next.js, Material UI, and Storybook, along with supporting task management and coordination.

At Jobis, I served as the Head of Front-End, leading the development of the entire frontend architecture and its integration with the backend API. Using React, Next.js, Redux, and Axios, I translated all Figma designs into scalable, performant, and maintainable interfaces. I collaborated closely with the backend team to plan and refine CI/CD processes, and initiated the implementation of integrated tests using React Testing Library. As part of the project’s technological exploration, I also developed micro-frontends using Vue.js and Svelte to evaluate their performance and suitability for specific features. In addition to technical leadership, I contributed to defining user-experience-driven business logic, ensuring that product decisions aligned with usability and interaction best practices.

At Miletus Education, I was responsible for building the frontend for a significant portion of the company’s online courses platform. Working closely with the product designer, I translated Figma prototypes into functional interfaces using HTML, CSS, and JavaScript. After completing the frontend layer, the components were integrated into a Laravel environment by a backend partner, while I continued to oversee the structure, quality, and consistency of the implemented UI. My role combined hands-on development with interface analysis, ensuring that the platform delivered a cohesive and user-oriented experience for online course delivery.

In partnership with WayShip, I led full-cycle web development and project management for a diverse portfolio of over 80 client projects. My responsibilities included client negotiation, scope definition, timeline planning, and Agile (Scrum) delivery management. I developed solutions using WordPress, WooCommerce, HTML, CSS, JavaScript, Bootstrap, React, and Vue.js, while also overseeing DevOps tasks such as hosting architecture, deployment preparation, and CI/CD workflows. Additionally, I supported clients with SEO, Google Ads, paid media, landing page development, and email marketing to enhance digital performance and user engagement.

During my internship, I worked primarily on Bash and shell scripting to support automated monitoring of climate models, including integration of an SMS-based alerting system. I also maintained and improved the organization’s web pages using HTML, CSS, JavaScript, and PHP, while contributing to UI/UX design and producing internal visual assets such as icons and banners. My main focus was the complete development of an Android weather-forecasting application written in Java. The app delivered 7-day forecasts, included GPS-based location detection to simplify city selection, and consumed weather data through REST APIs. I managed the full lifecycle of the application—from design and development to publication—and it surpassed 100,000 downloads.

Worked on the creation and editing of travel-themed banners, producing visual assets optimized for promotional campaigns and digital channels. Responsibilities included layout design, image treatment, color adjustments, and adapting materials for various formats while ensuring visual consistency and alignment with brand guidelines.
