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, an AI Automation Specialist and Software Developer focused on building practical workflows that streamline business processes and reduce repetitive work. Using n8n, Zapier, and Make, I connect applications, APIs, and AI tools to automate operations, move and process data, and create reliable workflows tailored to business needs.
I bring over four years of professional software development experience building and maintaining web applications in corporate environments. I combine that engineering foundation with AI automation to build solutions that are structured, reliable, and maintainable, helping businesses connect their tools, simplify operations, and spend less time on manual work.
