A search platform for Finnish second-hand marketplaces. Built solo end-to-end with AI-assisted development (Python/FastAPI · Vue · Docker).
Co-founded an Oulu founder community. Within month one: 5 events and seminars taught. Revenue rolls forward into new founder initiatives.
Help founders connect with the teams they need. I run education, evangelism, and events that match builders with the right people.
Long-running ambassador role for one of the most distinctive startup pitching events in the Nordics.
I'm a senior developer turned product owner. I bring product discovery and innovation management to teams that need both vertical and horizontal innovation — plus the speaking and voice-acting chops to translate that energy to product development, teams, and customers.
Linux has been my only OS for over 20 years, and I'm a long-time supporter of open source.
I enjoy building amazing products. It doesn't have to be new or customer-facing — I remember helping build a paint mixing machine, and with the right story in your heart you can find great joy in what you're building. I'm known to inspire my team, attach what we love to the product, and good vibes follow.

Pohde: consolidated hundreds of separate services into a single regional health-care platform serving thousands of citizens daily. Delivered ahead of schedule with a team of two.
Tosibox: took over a rebuild the team was about to abandon in favour of keeping the old site, reframed it around the Finnish folk story of the Red Fox, and shipped it. The relationship outlasted the engagement — Tosibox asked to keep working with me after I changed companies.

Built kaleva.fi for Kaleva, the largest newspaper in Northern Finland, serving thousands of concurrent readers. Migrated the legacy ColdFusion platform onto Django in pieces, under live traffic — never a full rewrite. That backend and much of the front end are still running today.
Joined a team that was struggling and helped turn it around; a month in, the Head of Kaleva Digital thanked me for it.
Also glued systems together for other customers — I like making the whole work better than its parts.

Jason is an exceptional developer and product owner. His unique approach to innovation has helped us achieve remarkable results.
Jason Brower, a pioneer in browser innovations, turning forks into startups and boldly stepping into lands where others haven't even dared to dream. The world needs more people like Jason - BIG HEART! ❤️
If people skills had a name, it would be Jason. I had the chance to work with him at Fab Lab, where I saw not only his ability to turn ideas into working prototypes, but also his natural talent for connecting with people effortlessly
Jason combines extensive experience in software and innovation with a proven ability to launch and grow multiple projects. His strength lies in solving complex problems with both strategic business understanding and creative thinking, making him a reliable and impactful contributor to any team.
Jason is the most people-centric person I know, equally at ease with a first-time student founder and a seasoned exec in the boardroom. It's the same instinct behind Trusted Cofounder and the podcast he hosts: read people clearly, draw them out, match them to what they actually need.
I've known Jason for years and he has been a force of nature ever since. He is friendly, helpful and extremely curious person. It also means he is always the first to know newest technologies and has the rare insight how to use them in the real world.
