I transitioned from teaching English in 2019 to software development in 2022, specializing in full-stack development with TypeScript, React, Node.js, and Golang. Currently working as a Full-Stack Developer, I contributed across development, infrastructure, and business strategy. I'm continuously expanding my skills in cybersecurity, DevOps, and backend architecture.

At One Panel, I work as a Full-Stack Developer contributing across multiple areas of the business. I developed new features for VPS automation using Go-Ansible, Ansible, and React, enabling customers to manage their virtual private servers directly through our dashboard. I created the company's new landing page to improve brand presence and customer acquisition. I worked on a Docker management system project using Golang, Gin, and GORM with PostgreSQL and MySQL, significantly improving customer container management capabilities. I led a team of developers, participated in the hiring and selection process for new developers, and provided ongoing support to the development team. I worked closely with the company leader on strategic business decisions, acting as his right-hand. Additionally, I contributed to the sales and marketing sector by creating and managing Google Ads and Facebook Ads campaigns to boost sales. I provided technical support for customers, identified and fixed bugs across our systems, and continuously improved user experience through strategic ideas and implementations.

I worked as a Freelance Software Developer, building web applications and providing solutions for various clients using modern technologies.

I performed maintenance on the company's main software, fixing bugs and adding new features, such as creating plans and defining user permissions according to the plan contracted. The technologies used included TypeScript, ReactJS, Tailwind CSS, ExpressJS, MongoDB, Socket.io and Docker. I developed an improved dashboard to manage customers, affiliates and other platform features. I also developed desktop applications with Electron JS to manage bots integrated with the Telegram API and bet automation, in addition to creating web scrapers and automations using Puppeteer, Cheerio and Socket.io. I updated applications originally developed in JavaScript, implementing TypeScript to improve security and facilitate code maintenance. At the same time, I created several PWAs (Progressive Web Apps) with VitePWA and ReactJS, integrated with an API built with ExpressJS and Postgres, which connected to the affiliates' betting houses. I transformed some of these PWAs into native applications with React Native. Finally, I migrated serverless applications, previously hosted on Heroku and Vercel, to a private VPS in Brazil, optimizing response speed and significantly reducing hosting costs.

I freelanced as a private English teacher online during the pandemic.

I worked at MUNDO HB, where I previously studied, to teach English classes at all levels, from basic to advanced. In the advanced classes, I conducted the classes entirely in English, demonstrating fluency and promoting total immersion in the language.
