Client feedback
Trusted inside existing teams and systems.
Feedback from clients whose products, platforms, and business workflows I helped improve over sustained project work. Published on freelancermap and translated from German where needed.
“Mathias worked with us as a full-stack software developer, continuously improving and maintaining our websites while delivering new features. His work contributed directly to their success. He was collaborative, dependable, flexible, and an excellent communicator, and completed every assignment carefully and to our full satisfaction. We are happy to recommend him as a highly qualified web development professional.”
Maike Krüger Product Owner · IU International University GmbH
“From planning and implementation through handover and operation, the collaboration on our internal tool was seamless. I would work with Mathias again anytime. Thank you!”
Dr. Richard Hritcu Physician · University Hospital St. Pölten
“Mathias supported us on a major project that was at risk of failing. He joined an existing codebase, quickly understood the system, and ultimately brought the project to completion independently. His ability to analyze, correct, and optimize existing Laravel processes was exceptional. For future database- and process-driven development, he would be my first choice.”

Flexible Laravel delivery
What needs to move forward in your Laravel project?
I focus the engagement on the constraint that matters most: shipping, modernization, or a technical decision that unblocks implementation.
Best starting point
Senior delivery inside the existing system
I work directly in the codebase, trace the affected workflows, implement the change, and take it through tests and an explicit release path.
Best starting point
A controlled modernization path
I map dependencies and business-critical flows, add regression tests, and upgrade the framework and packages in separately verified stages.
Best starting point
An independent decision with implementation context
I separate symptoms from structural constraints, make the trade-offs visible, and leave the team with a decision it can execute.
Flexible collaboration
Choose the working model that fits the problem.
The engagement follows the scope and responsibility. I can assess a codebase, own a defined project, join an existing team, or provide ongoing senior Laravel support.
Focused assessment
A bounded codebase or architecture review with priorities, tradeoffs, and a practical recommendation.
Defined project
A feature, integration, upgrade, modernization phase, or application area with a clear completion point.
Embedded delivery
Hands-on Laravel development inside your existing product and engineering rhythm.
Ongoing support
Continued senior delivery for products that need regular development, maintenance, or modernization.

Read the full modernization story Laravel · Livewire · MySQL · Tailwind · Vite · GitHub Actions
A multi-year B2B ordering, logistics, and billing platform for an international automotive manufacturer had to move from Laravel 8 to Laravel 13 while orders, inventory, invoicing, SAP exports, and operational workflows remained explainable and testable.

Protect business workflows first
The application covers dealer and company data, orders and promotions, stock and logistics movements, invoice and delivery PDFs, SAP files, and reporting. The upgrade had to preserve those workflows rather than only make Composer resolve.
Upgrade one framework version at a time
Dependencies, Livewire behavior, uploads, cart logic, PDFs, security boundaries, migrations, and frontend assets were modernized in stages. Every framework step stopped until PHP, browser, migration, and production-build checks were green.
Verify builds, migrations, and deployment
The finished system gained isolated browser flows, reversible migration checks, encrypted settings, private attachments, atomic order and logistics operations, targeted deployment workflows, and staging mail safeguards.
