- •Migrating existing workloads to K8s and need expert guidance
If you just need deployment configs for existing K8s cluster → see "Apps & Platforms" service instead.
Architecture Decisions
🏗️ Multi-environment: Every platform built with dev, qa, prod. Separate namespaces, configs, promotion workflows.
🌍 Multi-region: Within cloud provider multi-region deployment (e.g., us-east-1 + us-west-2). DNS failover. NOT cross-continent global load balancing.
💾 Managed services for data: Don't run databases/Kafka in K8s. Use RDS, CloudSQL, MSK. More reliable, easier to operate.
📝 GitOps first: If it's not in Git, it doesn't exist. Everything reproducible, auditable, version controlled. No clickops.
👨💻 DevEx focused: Developers deploy without ops tickets. Self-service within guardrails.

Apps & Platforms service includes K8s deployment configs and monitoring hooks - ready to deploy. This service builds the complete platform: full K8s cluster, GitOps workflow, monitoring stack, and multi-environment configuration.
Full-Stack Applications
Production systems that need proper architecture. Not simple CRUD apps - complex applications requiring distributed systems expertise, observability, and horizontal scaling.
Web applications and mobile apps with scalable backends. If AI can build your entire app, you don't need me.
Why Choose This Service
✓ Production-ready from day one: K8s configs, monitoring, stateless design. Not "MVP code that needs rewriting" - properly architected systems from the start.
✓ Built AND operated perspective: I've both built and run applications in production. I know what makes ops teams struggle. What I build is designed to be simple to operate.
✓ Complete ownership: One person building the entire stack means no "frontend vs backend" communication gaps. Faster decisions, consistent architecture, cleaner code.

- •Ongoing maintenance after delivery
- •Security audits if required by your industry
- •Compliance certifications (PCI DSS, SOC 2, HIPAA)
When You Need This
I build applications that require proper architecture because simple solutions will break:
- •High-load systems - Thousands of concurrent users, not dozens
- •Complex integrations - Multiple services, external APIs, real-time data processing
- •Distributed systems - Multi-region, high availability, proper state management
- •IoT backends - Device fleet management, MQTT, real-time telemetry
- •Multi-tenant SaaS - Proper tenant isolation, per-tenant scaling, security
- •Mission-critical systems - Healthcare, fintech, manufacturing - things that can't just 'restart and hope'
- •Real-time requirements - WebSockets, event streaming, low-latency operations
If your app is simple forms and CRUD workflows - use AI tools and managed platforms. Much cheaper, same result.

👤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.
