First production software at 15. First company not long after.

That first system — built for an asset management company — ran for almost ten years. Since then I've founded and operated businesses across healthcare, logistics, e-commerce, finance, government, real estate, recruiting, legal tech, marketing, cybersecurity, blockchain, AI, and space tech — writing the code and infrastructure myself. Whatever the problem, I build the solution from the ground up.

I've always been drawn to figuring out how things work and then building my own version. Started coding in elementary school — by 15, I'd shipped production-grade software used by an asset management company for client reporting and back-office operations. That system ran for almost a decade.

In parallel, I was building businesses. Seasonal products, physical sales, e-commerce, online storefronts, B2B sales cycles, distribution networks — whatever I could get my hands on. Built sales organizations and partnership networks before I could legally sign a contract. Each venture taught me something the last one couldn't, and the common thread was always being early to whatever came next.

I served 12 months in signals intelligence and cyber security for the Finnish Defence Forces. Specifics remain under obligation. It fundamentally shaped how I think about operational security, adversarial systems, and what's at stake when critical infrastructure fails. Started studying electrical and software engineering at university after — dropped out when the opportunity cost of not building became too high.

Healthcare & supply chain — procurement, logistics, and government tenders where mistakes affect real people. Finance & asset management — financial operations, consulting, advisory. E-commerce & retail — online and physical, B2B and direct, partnership organizations from scratch. Marketing & agencies — built and ran them. Real estate — property platforms and tooling. Recruiting & HR — hiring platforms, staffing operations. Legal tech — document signing, contract workflows, compliance. SaaS & enterprise software — accounting suites, operations platforms, CRMs. Self-hosted, multi-tenant, enterprise-ready. I've handled highly confidential data and built processes to work securely with institutional requirements.

More recently: blockchain protocols and DeFi infrastructure, AI-powered data processing, agentic swarms, and the security challenges they create, cybersecurity and offensive security tooling, I even took a run at space tech — designing low-cost satellite communication and location-based IoT devices. Didn't get funded, but the engineering was real. Participated in planning Finland's first biowaste-to-protein plant and reactor design — about as far from software as it gets, but the systems thinking is the same. I've shipped apps, SaaS products, games, autonomous agent systems, and institutional-grade platforms. Always early to adopt, always building at the edge.

Most of my professional work is under NDA. What's listed here are side projects and independent pieces — some built for clients but described at a general level.

Every project I take on gets a tailormade solution built from the ground up — not a template, not a fork, not a white-label with your logo on it. I sit down, understand the specific workflows, integrations, and constraints, and build exactly what's needed. Nothing more, nothing less.

Having run businesses myself, I know the pain of adopting new tools and the overhead that comes with it. I build things that fit into how you already work, not systems that force you to change everything. The goal is always less friction, not more.

I prefer ownership over delegation. I design the architecture, write the code, handle the infrastructure, and talk to the users. Not because I can't build teams — I've managed organizations of 30+ people — but because the best products come from people who understand every layer.

I think in cross-domain patterns. Healthcare logistics taught me how to think about fintech architecture. Intelligence work taught me how to think about security. Running sales taught me what actually matters to the person paying.

Let's build something

Whether you're planning a new project from scratch, need someone to take a stuck project across the finish line, or want a technical partner who understands both the code and the business — reach out. I'll tell you honestly what I think it takes and whether I'm the right fit.

Finnish, but I've backpacked across Europe and can call most places home. When I'm not building something, I'm surfing, snowboarding, or fishing — preferably somewhere with bad cell reception.
