Bio

Long-term builder, advisor and technology enthusiast.

My career has moved with each major technology wave, from early software and the web to mobile, immersive computing and AI. The constant has been helping organisations figure out what matters, what is feasible and how to turn ambition into useful products.

Professional profile

A strong blend of technical depth, product pragmatism and business understanding.

That mix has been especially valuable across both regulated and non-regulated industries, where innovation still has to survive the realities of delivery, adoption and business value.

I enjoy working at the edge of what is next, but I care just as much about whether the result can actually be delivered, maintained and trusted. That perspective has shaped work in consulting, product delivery, digital agencies, innovation leadership and speaking.

Alongside software development and technology strategy, I have broad experience helping teams navigate regulated environments such as MDR, GCP and the EU AI Act, while also working across FMCG, sustainability, gaming and construction contexts. That mix makes it easier to help customers understand modern technology not just as something impressive, but as something that should create a real advantage in their own business.

Timeline

From early home computers to AI, spatial computing and regulated digital health.

The through-line has been the same in every era: learn new technology by building with it, then help customers figure out where it can genuinely create value.

Early to mid 1990s

Started with apps, games and the early web

Commodore 64, Amiga 500, MS-DOS, Windows and the first web services

My first serious software work started on classic home computers and early PCs, building applications and games across platforms such as Commodore 64, Amiga 500, MS-DOS and Windows. As the web started opening up, that expanded into early websites and services, including a Finnish movie database site built long before modern publishing stacks made this kind of work easy.

  • Developed software across home computer and PC environments before the web became mainstream.
  • Moved naturally from standalone software into the first generation of web-based products and services.
Early 2000s

Built social platforms and mobile business

Student community platform and Unique United

I created a social media platform for Finnish college students years before Facebook became part of everyday life. At its peak it served more than 5 000 daily users and included chat, image sharing, user profiles and community features. Around the same time I helped ramp up the mobile department of the Finnish-Chinese startup Unique United.

  • Built a large student community service with real daily usage, social features and user management.
  • Expanded from web software into mobile, product growth and team building.
Mid 2000s

Joined Nokia as a bridge between engineers, leadership and customers

Nokia

At Nokia I often operated as a translator between management, engineering and customers. The work combined technology understanding, customer dialogue and practical product work across web, mobile and NFC or RFID-related solutions.

  • Bridged business and engineering conversations in a large international technology organisation.
  • Worked with customer meetings, mobile services and emerging connected-device technologies.
Late 2000s

Started my own consultancy company

Independent consulting and software delivery

After Nokia I moved into entrepreneurship and started building my own consultancy business. The focus quickly developed toward pharma and well-being, where technology choices had to support real-world quality, trust and domain understanding.

Early 2010s

Expanded into startups and funded innovation work

Syntax Error, Fishare and early Business Finland projects

I co-founded two additional startups during this period: Syntax Error in mobile games and Fishare as a mobile and web service for fishermen. This was also when the first Business Finland-backed projects entered the picture and innovation work became a more formal part of the journey.

  • Explored both entertainment and service-product angles through new ventures.
  • Began building experience in public innovation funding and application work.
Mid 2010s

Co-founded Make Helsinki

Technology, design, UX and cross-industry product work

My consultancy company merged with a creative agency, which became Make Helsinki. That significantly broadened the offering by bringing together technology, UI, UX and design under one roof. During these years we worked not only in pharma and clinical-trial-related contexts, but also across FMCG, sustainability, gaming and construction. At the same time, we started building early virtual reality prototypes and I began working with IBM Watson AI.

  • Built a more complete digital product company by combining engineering with design capability.
  • Worked across both regulated and non-regulated industries, which kept the perspective broad while healthcare depth continued to grow.
Late 2010s

Deepened the pharma focus and frontier experimentation

Make Helsinki

Business Finland-funded work continued, the pharma focus grew stronger and new gadgets, virtual reality and augmented reality became a larger part of the practical work. During this period I also co-authored a scientific journal article on tremor quantification using consumer product accelerometry.

  • Balanced regulated health delivery with experimentation in new interfaces and devices.
  • Expanded the role of scientific, clinical and evidence-driven thinking in software work.
Early 2020s

Entered a more international phase through acquisition

Healthware

Make Helsinki was acquired by Healthware, which expanded the international dimension of the work and created more room for emerging technology initiatives. I led work on a virtual-reality-based digital therapeutic that progressed all the way to a validated medical-device path, and I also worked on a growing number of AI-related initiatives, including helping customers understand and adopt AI in practical ways.

  • Led a VR-based therapeutic product where immersive design, clinical logic and regulated delivery had to work together.
  • Helped customers not only build with AI, but also understand how to use it responsibly and usefully.
Mid 2020s

Strengthened the new-technology focus inside EVERSANA

Healthware acquisition by EVERSANA

When Healthware was acquired by EVERSANA, the international context grew again and the Finnish team increasingly became known internally for new technology work. Alongside customer delivery, I kept expanding hands-on capability through 3D-printing-driven ecommerce, live AI concepts and independent web products such as KisaPlay.

  • Continued to connect advisory work with practical building, not just strategy language.
  • Used side projects and independent products to stay close to the realities of modern tooling and platforms.
Late 2020s and onward

Still researching, prototyping and testing what comes next

Hands-on exploration across AI, devices and future interfaces

The pattern has stayed the same throughout the years: learn new technologies by actually using them. That currently means evaluating the fast-moving wave of AI tools and models, testing a growing range of AR glasses, building prototypes and trying to understand what is genuinely viable for clients now and what may matter next.

How I work

A few principles behind the work.

  • Technology should create measurable value, not just visual novelty.
  • The best innovation work balances ambition, usability, delivery risk and compliance.
  • Use the right tool for the job, and step back from using a tool entirely when it does not genuinely improve the outcome.
  • Clear communication between business, design and engineering is a competitive advantage.
  • Hands-on experience matters when evaluating what is real, what is hype and what is worth investing in.

Today

Outside work

Forests, music, fishing, books, gadgets and a fairly full family life.

Outside professional work, life is a mix of family, forests, the sea, music, books, cooking and an ongoing stream of curiosity-driven side projects.

Outside client work, the same curiosity shows up in a more personal way through family life, outdoors time, books, music, sports and a constant stream of side projects and gadget experiments.

  • I live in Kirkkonummi, Finland, close to Helsinki, with my family, two kids and a dog.
  • I enjoy playing instruments and singing, even if enthusiasm still clearly outruns actual skill.
  • Fishing is a long-time favourite, and I also love forests, nature and the sea, including mushroom picking when the season is right.
  • I play floorball and occasionally other sports as well, and I enjoy live music both on stage in small ways and in the audience in much bigger ones.
  • I constantly experiment with new technology through small hobby projects, because the fastest way to understand a tool is still to build something with it.
  • I like cooking, reading books, building hobby projects and extending the house with home automation and new gadgets, which means there is almost always one experiment too many in progress.
