Building Reliable Web Apps and Practical Automation Workflows
I turn business requirements into maintainable web applications, internal tools, and lightweight workflows for tracking, approvals, notifications, and reporting.
The person behind the work
I'm Hubert Lemuel Berja, a software developer with over four years of professional experience building and maintaining web applications. My work focuses on practical business requirements, responsive interfaces, clear application structure, and maintainable code.
I'm also expanding my capabilities in workflow automation with n8n. Through hands-on projects, I'm learning how to connect tools, validate and move data, trigger notifications, and reduce repetitive manual work.
