Show less 📋 Project Management System✔️ As a Senior Full Stack Developer, I took on the challenge of migrating a legacy system built in Vanilla JavaScript to a modern ecosystem based on React, Node.js, and cloud technologies such as GCP. The original platform faced several issues: maintenance difficulties, low scalability, and a steep learning curve due to its outdated architecture. I designed and implemented a modern, scalable, and sustainable ecosystem by integrating current technologies and establishing a solid foundation through well-structured designs, architectures, configurations, and development tools. This approach transformed the platform into an innovative solution, enabling faster development of new features and significantly reducing implementation times.✔️ In addition to leading the technological migration, I trained and mentored the team in using the new tools and methodologies. I introduced best development practices and modern technologies like Redux Toolkit, React Testing Library, and customized configurations to maximize productivity with tools such as VSCode. My efforts not only enhanced the technical capabilities of the team but also optimized the development cycle and facilitated the adoption of these technologies across the team.✔️ Due to my experience and performance, I was appointed as interim Team Lead, taking on a multifunctional role. I coordinated distributed teams across Canada and other regions, acting as a Scrum Master and managing agile ceremonies, sprint planning, and stakeholder meetings. I also reported progress to the Project Manager and highlighted individual contributions, fostering a collaborative and rewarding team environment.✔️ I remained an active Full Stack Developer, designing and implementing key features for the platform. My contributions helped maintain a customer satisfaction rating of 4.7/5, ensuring that deliverables were of high quality, aligned with client objectives, and supported by technical solutions.
