What I've Actually Done
People don't buy service categories. They buy proof.
Turned legacy platforms profitable
7 media platforms at Rakentaja-mediat: 60% infra cost savings, 3x faster performance. 40+ site migration to AWS with Docker and Terraform.
Marketplace from zero to users
Built Willit.fi in three months — a two-sided marketplace from zero to production. 629% search ranking growth.
300K users, 700K monthly visits
I manage platforms with 300,000 registered users and 700,000 monthly visits. I know what scales and what breaks.
AI that actually works
AI agents, chatbots, automation workflows — but only when AI is actually the best solution. I'll tell you when it's not, too.
How I Work
First I understand your business, then I build
I don't start coding before I know what your business actually needs.
01
I Listen
I learn your business before talking technology. What works? What doesn't? Where do you want to be?
02
I Map
Where's the money leaking? Where's the opportunity? What technical solution will have the biggest impact?
03
I Build
Practical solutions in your codebase. No PowerPoints — working code. Highest impact first.
04
I Grow With You
This isn't a project — it's a partnership. Monthly results, continuous improvement, honest feedback.
Values
- I work in your codebase
- I say no when that's the right answer
- Honest assessment — even when it's uncomfortable
- Long-term partnership
AI in Practice
Half the AI projects I evaluate don't need AI. I'll tell you that before you waste €50K on the wrong solution.
Why Me
The Fractional CTO Who Actually Builds
Most fractional CTOs are ex-corporate managers. I also code, run a business, and study business management. That's different.
I Build and Lead
I don't consult from the sideline. I work in your codebase, make architecture decisions, and own the delivery.
Full Stack, Full Picture
From embedded systems to modern web, infra to mobile. Plus business studies. I understand both the boardroom and the code editor.
Fairer Price
Same expertise as an €8-10K/mo Helsinki agency — without the office rent, middlemen, and overhead.
Why Me
Code + business.
Most devs can't speak strategy. Most strategists can't read code. I do both.
Entrepreneur who understands business
I run my own company and study business management. I understand budgets, sales processes, and board reporting — not just architecture diagrams.
I say no when that's the right answer
I don't sell hype. I've built AI agents, chatbots, and automation — but I'll always tell you first whether AI is actually the right solution for your problem.
Oulu-based — same expertise, fairer price
World-class expertise without Helsinki office rent. One experienced builder who owns everything — no teams, no overhead, no middlemen.
