As a Full Stack Developer with solid experience in software development and database management, I specialize in process analysis, design and implementation, problem-solving, and unit testing. In my most recent role, I worked on projects involving PostgreSQL, PostGIS, APIs, ExtJs, and PHP, focusing on building and maintaining scalable and efficient backend solutions. My contributions included: * Backend development in PL/pgSQL on a PostgreSQL database, creating new functionalities and maintaining existing code. * Creation and maintenance of complex custom reports, optimized for performance and efficiency. * Implementation of graphical user interfaces (GUI) to facilitate user interaction with the system. * Execution of data migration from client databases to our infrastructure. * Database optimization, API development and integration, and handling geospatial queries with PostGIS. Previously, as a Back-End Developer for SME management and inventory systems, I worked on database relationships, routes, middleware, JWT authentication, encryption/hashing, controllers, and access control. These solutions empowered businesses to effectively manage sales, costs, customers, and products across multiple stores. I am recognized by colleagues for strong problem-solving and analytical skills, forward-thinking planning, and a creative yet functional approach to development challenges. I thrive in collaborative environments and knowledge-sharing, while remaining fully capable of working independently. Currently, I am working independently while seeking new opportunities to contribute, grow, and continue learning.
