~/about
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.
~/services
I am fully booked at the moment, but this is the kind of work I do.
Full-stack web applications, platforms and internal tools, built with Vue, React, Python, Node.js or PHP, including the servers they run on.
Interfaces that are clear to use and realistic to build. Wireframes, prototypes and finished designs, implemented by the same person who designed them.
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.
Connecting the tools you already use through APIs, custom plugins and automated workflows for services like Slack, Discord, Zendesk and WordPress.
