Žan Koren Kern

Technical Project Manager & Software Developer

I lead web software projects from the first client meeting to handover, and I build them as a full-stack developer.

Based in Ljubljana, Slovenia

Open to jobs and projects

About

I lead projects from the first client contact to handover: sales meetings, specifications, quotes and a leading a team of developers.

Most of my experience is in custom ERP systems: I developed a range of modules, from project management and CRM to document management and HR. I work mainly in PHP on a custom MVC framework and more recently with Laravel and Vue.js. I have also built API integrations and AI features with the OpenAI API.

I joined BPLANET in 2022 as a junior engineer, moved on to full-stack development and then to project management. I graduated in computer science from the University of Ljubljana. Knowing both sides means fewer surprises: I know what a feature costs to build, and I know why the deadline matters.

Fantasy football predictor

My own project

A web app for the Ekipa SN fantasy football game. Using data from every match of the season, it predicts how many points each player will score in the next gameweek. It then instantly calculates the optimal team within the budget, formation and per-club limits. It also backtests each prediction method on past gameweeks to measure how accurate it was.

Internal business systems, including for a transport company

Project manager & developer

Custom internal business systems. Web admin platforms with APIs for mobile apps, built for clients including a transport company, that bring a company’s daily operations into one place: document management, employee absences, notifications and automation of manual tasks, such as AI processing of incoming email.
