Building Realiable Software and Practical Automation Systems
I turn business requirements into reliable applications and automated workflows by connecting APIs, data, CRM platforms, AI services, and business tools.
The person behind the work

I’m Hubert Lemuel Berja, an AI Automation & Implementation Specialist and Software Developer focused on building practical systems that connect business processes, applications, data, and AI. I design and implement workflows using n8n, CRM platforms, APIs, webhooks, JavaScript, databases, and AI integrations, with an emphasis on reliability, clear system logic, and maintainable automation.
I bring 4+ years of professional software development experience building, maintaining, debugging, and integrating web applications in corporate environments. I combine that engineering foundation with hands-on automation experience to translate business requirements into structured workflows, connect systems, troubleshoot integrations, and improve how day-to-day operations are carried out.
