About
One developer. Deep focus.
I'm Andreas Sørbye Styltsvig, and I run AStyltsvig Consulting as a single-person practice out of Vanløse, Copenhagen.
I've worked in IT and web development for more than a decade, and the primary focus of the practice is building and operating enterprise-grade platforms — systems that organisations run their business on, year after year.
My preferred stack is Laravel and Vue, but I'm flexible by default — in practice, I adapt to whatever the client is working in and whatever codebase is already on the table. The outcome is the same: platforms that hold up in production over time.
Several of these platforms are currently in daily production — booking systems, ERP, and CRM supporting core operations and serving thousands of end users. All built and operated by a single developer.
What I help with
How I can add value.
- Designing, building, and operating enterprise platforms on a modern stack
- Continued development and long-term operation of existing codebases
- Migrating older sites (typically WordPress) to modern, static stacks
- Infrastructure administration
- Advising on technical architecture, vendor selection, and operational setup
Engagement
How I work.
- Rolling engagements over fixed-price projects — I build the right thing, not the agreed thing
- Direct contact from first conversation through ongoing operations — same person all the way
- AI used openly and transparently as part of the workflow, not hidden away
- Codebase and process hygiene first; features only hold up when the foundation does
- Continuous updates over large drops — fixes and features reach users in days, not weeks
- Normal working hours; sprint culture doesn't belong in long-term operation
Background
A decade of deliberate practice.
I hold a Professional Bachelor's in Software Development from Copenhagen Business Academy (Cphbusiness Lyngby, 2019). The software career was properly kicked off at Prolike ApS the following year, where I was outsourced to Oticon and given responsibility for a major migration from on-prem CI/CD (Jenkins) and SVN to a cloud-based platform on Azure DevOps — with modern CI/CD pipelines and Git-based workflows. That foundation is what I went full-time freelance on in 2020.
Today I work across a broad range of enterprise platforms in close, daily dialogue with clients — from core business systems and real-time platforms to solutions handling thousands of end users across many organisations.
