About Me

Hello, I’m Josef

From Sweden, I am currently engaged in entrepreneurial ventures. I work on services, web applications, and open-source systems. I aim for practical, scalable solutions that provide flexibility and room for creativity, with a strong focus on user-centered design to meet real user needs.

Areas of Focus

• Web applications with responsive, user-centered designs
• Scalable monolith / microservice architectures
• Open-source projects.
• IoT solutions involving microcontroller programming, primarily using Python and Arduino.

Technical Stack

Frontend:

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

Backend:

• TypeScript, Node.js, Express.js
• PostgreSQL, MongoDB, Redis, Prisma,
• GraphQL, REST, gRPC, SOAP
• Python
• Kafka, Nats

DevOps & Tools:

• Docker, Kubernetes
• Git, CI/CD pipelines
• NGINX,
• Grafana, Lighthouse, Prometheus, OpenTelemtry
• Jest, Pytest
• Raspberry Pi, Arduino

Familiar Tools:

• Svelte, Vue
• Terraform, Ansible
• MATLAB
• GitLab CI
• Slack, Jira, Asana

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 - research papers, literary works, non fiction, 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 began programming because I enjoy solving puzzles and challenges that require logical thinking. My interest in natural sciences, especially chemistry and physics, shapes how I approach solutions and problems e.g. applying scientific principles to build practical improvements.

What began as solving puzzles has grown into building practical tools that solve problems. Whether optimizing security checks with Vibe-Guard or integrating systems through S.I.R.I.U.S., I try to create straightforward solutions that make technology genuinely useful.

What makes me unique:

• Mathematical rigor applied to practical implementation - I enjoy solving problems using mathematical rigor and principles. I only commit to designs or solutions when I can understand why and can provide a proof or solid reasoning behind them.

• Full-stack systems thinking - Architecting solutions that bridge theoretical concepts and practical application is central to how I create and maintain diverse systems. The most effective solutions are well thought out and truly move the needle without risking the stability of the whole system.

• Independent & research-driven development - I pursue research by curiosity and practical relevance, blending certain academic concepts with real-world challenges, then to apply insights that matter to the problems I encounter.

• Meaningful impact through technology - I try to focus on building, reliable software that genuinely improves everday tasks and workflows. I believe in creating tools that make a real difference in how people work and live.

When I’m not coding, I enjoy exploring new technologies, contributing to open source, and sharing knowledge with the developer community. I believe collaboration and continuous learning are key to building better software
