Software Developer Java & Spring Boot • Backend • Mobile Building production-oriented applications, APIs and developer projects.
I’m Syed Zubyl N, a software developer focused on building practical software and learning through real implementation.
My primary engineering focus is Java, Spring Boot, backend development, REST APIs and databases. I also build mobile applications using Flutter and Dart and work across modern application stacks when a project requires it.
I like understanding systems from the fundamentals, building things end-to-end, experimenting with infrastructure and turning ideas into applications that can actually be deployed and maintained.
