About Nadim
Since 2012, I have been working as a Web Developer, specializing mainly in backend development and enterprise web applications. Throughout my career, I have worked with different technologies including PHP, Java, and .NET, participating in projects for multiple industries and business environments.
I have extensive experience developing scalable and maintainable backend systems, REST APIs, integrations, and custom business applications. My work has included application maintenance, performance optimization, implementation of new features, debugging, and database management. I am comfortable working with complex business logic and adapting to different architectures and frameworks depending on project requirements.
I have strong experience with relational databases such as MySQL, Microsoft SQL Server (MSSQL), and Oracle, including query optimization, stored procedures, database design, migrations, and performance tuning.
Although backend development is my main expertise, I also have experience with frontend technologies and modern frameworks, allowing me to contribute to full-stack projects and collaborate efficiently with frontend teams.
I have worked in agile environments using Scrum and Kanban methodologies, collaborating with multidisciplinary teams and participating in technical analysis, code reviews, and continuous improvement processes.
I consider myself a proactive, analytical, and adaptable developer, focused on delivering clean, efficient, and reliable solutions while continuously learning new technologies and best practices.
