Hi, I'm Leon Potgieter

ERP & SOFTWARE DEVELOPER

I help businesses run on better software — ERP customization, full-stack apps, and AI integrations.

ABOUT ME

ERP Developer & Software Builder based in Austria

I work as an Odoo ERP Developer at multioss.com, building and customizing ERP systems for SMEs and larger enterprise clients. That means writing Python modules, designing business workflows, and staying in close contact with accountants, logistics managers, and operations leads — translating real business problems into working software. Alongside ERP, I build independent products and am fascinated with business and life automation via Agentic AI. As a career changer with a master’s degree in social sciences, I bring a rare mix of business empathy and technical depth.

MY SKILLS

   ERP & Python

My primary language is Python, used daily in Odoo ERP module development. I design and customize business workflows for clients in accounting, logistics and operations — and build standalone backend services when a full ERP isn't the right fit.

   Frontend

Comfortable with HTML, CSS and vanilla JavaScript. I've built React apps and static sites, and prefer keeping the frontend lean — reaching for frameworks only when the complexity genuinely demands it.

  DevOps & Cloud

Certified Microsoft Azure Administrator (AZ-104). I work with Linux, Docker, GitHub Actions and Google Cloud Platform for deployments, and keep production environments tidy with proper CI/CD pipelines.

   AI Engineering

I build production-grade AI systems with LangGraph for agentic orchestration, versioned prompts tracked with metric deltas, eval suites, and model choices backed by benchmarked numbers — not vibes.
