What I'm looking for

I'm available for fully remote roles and am comfortable working across time zones and shifts.

I’ve built and support two live business software systems used daily: a Flutter field-operations app for a truck fitment and auto-electrical team, and a Next.js tutoring platform that replaced a third-party service.

Since January 2026, my freelance work has focused on AI automation, internal tools and custom business systems. I handle requirements, architecture decisions, deployment, debugging and ongoing support, using AI-assisted development while keeping customer data out of personal AI tools.

Before that, I diagnosed faults in vehicle electronics and connected reporting systems at Mix Instruments and Diagonal Transport Solutions. At JVPS Civils & Engineering, I led installation and commissioning work and wrote technical SOPs and risk assessments. I hold CompTIA A+, Network+ and IT Operations Specialist (CIOS) certifications.
