Hi, I'm Niklas,
Founder, WigertzTech AB
Complete Technical Solutions
Technical problem solver who ships complete systems. Hardware products, cloud platforms, applications - I build it, document it, and hand over a working system.
Perfect for companies that need things built, not people managed. I build, you own it.
15+ years building systems from embedded hardware to enterprise cloud. Built consumer hardware product from scratch (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 fitness tech. Based in Leksand, Sweden.

From idea to launch. I build it, you own it. Fast, focused, finished.
Companies I've Built For
What I Build
Full-stack product development across hardware, software, and infrastructure. From concept to production.
Product Development
Complete physical products from idea to production. Sensors, compute, software, enclosures — standalone or connected.
- Idea to deployment — hardware, software, production tooling
- 1000+ units shipped in production
- Custom or off-the-shelf hardware, your call
Best for: Working product in weeks, not a team to manage
Platform Infrastructure
Production-ready Kubernetes platforms, CI/CD pipelines, and cloud infrastructure with observability and security.
- Everything as code — reproducible, auditable
- Built AND operated platforms in production
- Clear handoff with docs & team training
Best for: Reproducible platforms, not ongoing consulting
Full-Stack Applications
Web and mobile applications with modern stacks. React Native, Next.js, scalable backends with production deployment.
- Production-ready from day one — not MVP code
- Complete stack ownership, no communication gaps
- Built to be simple to operate & troubleshoot
Best for: Complex systems & integrations, not simple CRUD
Technical Expertise
Targeted expertise for teams with existing systems. When you need depth, not breadth.
- Specific expertise your team lacks
- Architecture review & unblocking
- Short-term depth, not long-term augmentation
Best for: Specific problems for days to weeks, not months
👤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. Master's in Electronics Design Engineering, Linköping University.
