Infinito Aktiebolag

Software architecture
that holds up.

Architecture, backend systems, fractional CTO work, and AI integration. 18 years of doing this — mostly from Sweden, for companies everywhere.

What I do

Design it.
Build it.
Keep it running.

From early planning through hands-on building to team support — I work across the full range of what's needed.

Software Architecture

Web applications, multi-tenant SaaS, API design, and backend systems. Built to last — and to be maintained by whoever comes after me.

AI in Practice

Integrating AI into how teams actually work — code generation, review, internal tools. What saves time, not what sounds impressive.

Code generation AI-assisted review Internal tooling

Fractional CTO

Technical due diligence, codebase reviews, engineering process work, and translating between what the business needs and what the code can do.

Due diligence Code reviews Tech strategy

Backend & Full-Stack Engineering

PHP and Laravel backends, Vue.js frontends, search systems, real-time features. The kind of work that keeps platforms running day to day.

How I work

Flexible
by default.

I take on both short engagements and long-term work. Some clients need a few weeks of architecture review. Others need someone embedded in their team for months. Both are fine.

Planning & architecture

System design, technical strategy, choosing the right stack. I do this before anyone writes a line of code, or to untangle something that already exists.

Building & delivery

I write production code. Laravel, Vue, APIs, search systems — whatever the project calls for. I ship working software, not just recommendations.

Team support & advisory

Code review, mentoring developers, fractional CTO work. I help teams get better at making technical decisions on their own.

I work remotely across time zones. Communication is async-first — clear written updates, calls when they're useful. No standups for the sake of standups.

About

Christian Fynbo

I live in the Swedish archipelago with my girlfriend and our three kids. I work remotely with companies across Europe and beyond.

Fluent in Danish, Swedish, and English. Direct, calm, and I prefer getting things done over talking about getting things done.

Technical depth

Tools I
actually use.

Everything here comes from production work, not side projects.

Pragmatic over theoretical

Decisions based on what works in production, not what looks good on a diagram.

Long-term maintainability

Code that the next person can actually read and work with.

UX awareness

I think about the person using it, not just the code behind it.

Attention to craft

I care about getting it right. That tends to rub off on the teams I work with.
