About me

I wear many hats: developer, UI designer and teacher, and a gamer at heart. I've spent my career building products where good design and solid engineering meet, from educational games used in classrooms worldwide to healthcare and recruitment platforms. Today I run Postari Technologies and work as a Senior Lecturer and curriculum coordinator in the Artificial Intelligence and Data Engineering programmes at Satakunta University of Applied Sciences, teaching LLMs, databases, software architecture and server-side development.

Web & App Development

Full-stack web applications, platforms and internal tools, built with Vue, React, Python, Node.js or PHP, including the servers they run on.

UI & UX Design

Interfaces that are clear to use and realistic to build. Wireframes, prototypes and finished designs, implemented by the same person who designed them.

AI Consulting & Training

Practical help with bringing AI and LLMs into your product or organization, plus training for teams, backed by years of teaching AI at university level.

Integrations & Automation

Connecting the tools you already use through APIs, custom plugins and automated workflows for services like Slack, Discord, Zendesk and WordPress.
