Hi, my name is Gilson Oliveira, and I’m a Senior Fullstack Developer with over 5 years of experience working on web and mobile applications, primarily using React, React Native, Node.js, and other modern technologies. I’ve had the opportunity to work in diverse environments, including both startups and large-scale organizations across Brazil, Europe, and the US. In my most recent role, I’ve been heavily involved in building full-stack applications, focusing on performance, scalability, and seamless user experiences. I’ve worked extensively with: Front-end technologies like React.js, Next.js, and React Native. Back-end development with Node.js, PHP, and microservice architectures. Cloud environments, particularly with AWS and Microsoft Azure, utilizing serverless architectures and deploying APIs. I’ve also led projects that involved integrating third-party APIs, ensuring security protocols, and automating testing. One of my recent projects was building a chatbot for a FinTech company, integrating OpenAI’s GPT models for customer support automation.
