Technology & Focus
My work is built on a clear technology stack with defined quality standards.
Frontend
Angular
All versions from Angular 2+. My primary frontend framework for complex business applications.
TypeScript, RxJS, Angular Signals
Type safety and reactive programming as the foundation for maintainable code.
UI & Styling
Angular Material, TailwindCSS. Strong sense for intuitive user flows and interface structure.
Testing
Cypress, Playwright — end-to-end and component tests.
Frontend Architecture
View-Container pattern and other structural patterns for maintainable Angular applications.
NgRx
State management with NgRx Store, Effects, and Component Store.
Backend
C# ASP.NET Core
API-oriented backend development with the .NET ecosystem.
Entity Framework Core & PostgreSQL
ORM and database integration. 3-layer architecture (Controller → Service → Repository).
NestJS & Node.js
Additional backend experience with the JavaScript/TypeScript ecosystem.
DevOps & Tooling
Git, Docker, Azure DevOps, AWS, Jira, Scrum/Agile Workflows, SVN
🏥 Specialisation
Domain Focus: Medical Technology
Hands-on experience with clinical software, DICOM integration, and regulated MedTech environments.
Practical DICOM Experience
Extraction and processing of data from DICOM-RT objects — specifically RTStructureSet and RTPlan
Integration of DICOM data into clinical software workflows (surface-guided radiation therapy)
Encrypted communication with medical hardware (LINAC) in clinical environments
UI/UX design for clinical workflows, including FDA usability testing requirements
Regulatory Context: Experience developing software in regulated MedTech environments with traceability, validation, and quality requirements.
Note on FHIR: No direct project experience yet; familiar with the standard at a conceptual level.
Angular and C# .NET expertise is domain-independent. MedTech is a specialisation, not a limitation.
Engineering Principles
These standards apply to every engagement — not aspirational, but actively enforced:
Test Coverage
Meaningful unit and integration tests as part of delivery, not as an afterthought.
SOLID Principles
Consistently applied, especially Single Responsibility and Dependency Inversion.
Extensibility
Architecture decisions are made with future changes in mind.
Readability
Code is written for the next developer, not just the compiler.
Smart/Dumb Components
Clear separation of logic and presentation in the frontend.
3-Layer Architecture
Clean separation of concerns: Controller, Service, Repository.
Reactive Programming
RxJS / Angular Signals used purposefully for state and async flows.
You can count on Fabian.

I work on every product as if it were my own.
Proof & References
Client Testimonials
Mr Birke was instrumental in the design, development, and stabilisation of our system. In collaboration, Mr Birke demonstrated a very reliable, independent, and transparent working style. I recommend Fabian Birke unreservedly for MedTech and HealthTech projects.
His contributions to practical UI/UX designs were of central importance, particularly during the usability testing phase as part of the FDA approval.
I worked with Fabian for half a year and it was a pleasure! His knowledge and expertise helped us create a solid foundation for a new project that we will work on now for years. Communication and transparency was amazing so working with him in our team was a blast!
Fabian is a fantastic developer with extensive knowledge of web technologies. He has a very high standard of quality and always thinks beyond the obvious.

Frequently Asked Questions
Availability
When are you available?
I am currently available for short-term projects. My main project ends in late October — after that I am available for a new full-time collaboration.
How quickly can you start?
Short-term projects can start promptly. For long-term engagements, I recommend getting in touch at least 4 weeks before your desired start date.
Collaboration
Do you work remotely or on-site?
I work remotely or hybrid. For on-site work, I am available in the Salzburg, Rosenheim, and Munich region.
What does day-to-day collaboration look like?
I integrate into your existing processes — daily or situational standups, async communication via your ticket system or teams, and clear alignment with the project lead.
Do you work with small teams or startups?
Yes. Team size doesn't matter — what matters is whether there's a good technical and personal fit.
MedTech / Compliance
Do I need to be in the MedTech space?
No. Angular and C# .NET are domain-independent. MedTech is my specialisation, not a requirement.
Communication & Process
What does the first contact look like?
I respond within one business day. Typically, I then propose a 30-minute introductory call.
What if a project grows larger than expected?
I communicate early when scope or effort changes — no surprises at the end.
