Fullstack Angular NodeJS developer
Category : Web development
I am a Full-Stack Developer specializing in architecting scalable Angular frontends and robust Node.js backends. My expertise lies in bridging complex client-side interfaces with efficient server logic and relational databases, specifically PostgreSQL.
On the frontend, I engineer structured, highly maintainable single-page applications and dynamic user interfaces using the Angular framework. For backend development, I architect robust Express APIs, implement secure JWT authentication endpoints, and design structured PostgreSQL database schemas, encompassing complex query optimization and data seeding.
I have practical experience building complete, end-to-end deliverables, such as custom CMS platforms, managing the entire project lifecycle from database design to frontend integration. My development workflow incorporates industry-standard tools like GitLab for strict version control and Docker for containerizing applications, enabling scalable and reproducible deployments. Additionally, I leverage server management utilities like WinSCP and PowerShell to maintain secure and structured environments.
By independently managing both sides of the stack, I provide efficient, end-to-end delivery of MVPs and comprehensive web applications. This approach ensures seamless integration between the client and server, maintaining strict architectural integrity, security, and optimal system performance.
