About Me

Hello, I’m Josef

From Sweden, I am currently working on entrepreneurial ventures. I often work on services, web applications, and open-source systems. My main focus is on building lasting solutions that combine technical expertise with practical implementation.

Areas of Focus

I specialize in building:

• Web applications with responsive, user-centered designs
• Scalable microservice architectures
• Open-source projects that solve real problems
• IoT solutions that extend the capabilities of common hardware

Technical Stack

Frontend:

• JavaScript, TypeScript, React, Next.js
• HTML, Tailwind CSS

Backend:

• TypeScript, Node.js
• PostgreSQL, MongoDB, Redis
• GraphQL, RESTful APIs, gRPC, SOAP
• Python

DevOps & Tools:

• Docker, Kubernetes
• Git, CI/CD pipelines
• NGINX, Prometheus
• Grafana, Lighthouse
• Jest, Postman
• Slack, Jira, Asana
• Raspberry Pi

Familiar Tools:

• Svelte, Vite, Astro, Vue
• Terraform, Ansible
• MATLAB
• GitLab CI
• Gradle

When I’m Not Building

I used to be a chef, which taught me that great results come from understanding the fundamentals, working with quality ingredients, and iterating until it’s right. That mindset stuck with me.

These days, I’m usually:

• Cooking - Still love experimenting in the kitchen
• Mountain biking - Gets me out of my head and into the moment
• Running - My thinking time, where most of my best ideas happen
• Reading - Tech articles, documentation, and anything that expands my perspective
• Tinkering - Smart energy systems, automation, and finding creative solutions to everyday problems

I believe that people are naturally curious about the world and its endless possibilities. The more diverse your experiences, the richer your ideas become, and that’s where the magic happens.

My Journey & What Makes Me Unique

I started coding because I rediscovered that childhood feeling of being able to tinker with things. It began with my passion for cooking! the satisfaction of taking raw ingredients and transforming them into something greater. That same creative energy led me to electrical engineering and now to coding, where I can tinker with systems and build tools that solve real problems.

What began as simple scripts has evolved into a passion for building tools that make people’s lives easier. Whether it’s automating security checks with Vibe-Guard or connecting disparate services with S.I.R.I.U.S., I believe technology should work for us, not against us.

What makes me unique:

• Mathematical rigor meets practical implementation - I love solving and applying mathematical formulas and behavioral analysis to solve complex problems. My work ranges from Shannon entropy market analysis to real-time queue-based concurrency systems that can process 5M packets per second.

• Full-stack systems thinking - I enjoy architecting complete solutions that bridge the gap between theoretical concepts and real-world applications. Through building diverse systems, I’ve learned that the best solutions are often the simplest ones that solve one problem really well. Whether it’s reducing document formatting from 3 hours to 30 seconds or building security scanners that fit naturally into developer workflows, I focus on creating tools that people actually want to use.

• Independent research-driven development - I pursue research out of my own curiosity, whether it’s sustainability metrics, EU directives, ESG requirements, financial markets and behavioral theory, or machine learning applications like circadian rhythm analysis and pattern recognition. My projects combine this independent academic depth with commercial viability. Whether it’s applying Shannon entropy to predict market volatility, building high-frequency trading simulation frameworks, or implementing local first AI with anomaly detection, I find the intersection of theory and practice fascinating.

• Meaningful impact through technology - I try to build production-ready systems that help people solve real problems, from mathematical modeling in C++17 to full-stack web applications. Whether it’s trying to save hours of manual work, protect against security vulnerabilities, or make complex analysis accessible, I show up every day focused on creating solutions that might genuinely improve people’s lives and work.

When I’m not coding, you’ll find me exploring new technologies, contributing to open source, or sharing what I learn with the developer community. I believe in building things that last, both in code quality and user impact.
