Selfi

Freelance Backend Developer

Selfi • Freelance

Nov 2024 - Present • 1 yr 7 mos

Working as a freelance backend developer specializing in PHP applications (Laravel, Symfony), helping clients build, improve, and scale their systems. My work includes debugging complex issues, improving API integrations, and optimizing backend performance in production environments. I frequently work with existing codebases, quickly understanding system architecture and delivering clean, reliable solutions without overengineering. In addition to maintenance and improvements, I design and develop new features from scratch, including RESTful APIs, integrations with third-party services, and backend logic for complex applications. I also collaborate closely with development teams, providing technical guidance and helping improve development and integration processes. This includes defining best practices, reviewing architecture decisions, and ensuring maintainable and scalable solutions. I support teams with Docker environments and CI/CD pipelines, helping streamline development workflows and deployments across environments. Additionally, I contribute to the early stages of new projects by proposing technical solutions, defining system architecture, and providing estimates for application development. My focus is on delivering practical, efficient solutions that solve real problems while maintaining high code quality and long-term scalability.
