Hi, I'm Niklas,
Founder, WigertzTech AB
Complete Technical Solutions
Technical problem solver who ships complete solutions. Hardware, firmware, cloud, apps - whatever the blocker is, I build it, document it, and hand over a working system.
Perfect for companies that need problems solved, not people managed. I build, you operate.
15+ years building systems from embedded hardware to enterprise cloud. Founded IoT startup (1000+ units shipped), delivered platforms for Volvo and other Fortune 500s. Track record of rapidly mastering new domains - from game dev infrastructure to automotive security to consumer hardware. Based in Leksand, Sweden.

👤About
15+ years building systems across the full stack - literally. From designing PCBs and writing firmware to architecting enterprise cloud platforms. I've worked every layer: embedded systems, IoT hardware, mobile apps, backend services, DevOps, and enterprise cloud architecture.
Track record of rapidly mastering new domains to deliver critical value. Game dev infrastructure? Built complete Unity CI/CD platform. Automotive security? Delivered compliance frameworks for Volvo's global platform. Consumer hardware? Shipped 1000+ IoT devices from circuit design to market.
Not a specialist in one narrow domain - I'm the person you bring in when the problem spans multiple domains and you need someone who can connect all the pieces. I don't just claim full-stack expertise, I've actually built at every layer professionally.
Based in Leksand, Sweden, working primarily with Swedish startups and scale-ups. Master's in Electronics Design Engineering, Linköping University.
