Julian
About this gig
My Core Strengths:
- Modern Angular Mastery: Expert in Angular 21+, Signals, and Standalone Components for maximum performance.
- Bulletproof Testing: I don't just "check" the code. I write Unit Tests in Jest/Jasmine.
- Clean Architecture: I use RxJS and NgRx for robust state management and follow "Clean Code" principles for long-term scalability.
- Performance First: I implement Lazy Loading and OnPush Change Detection to ensure your app is lightning fast.
What You Get:
- Full-Stack Ready Frontend: Perfectly integrated with your REST or GraphQL APIs.
- Responsive UI: Pixel-perfect implementation from Figma/Adobe XD using Tailwind CSS or Angular Material.
- Enterprise Standards: Scalable folder structures and modular design.
- Zero Technical Debt: Code that is documented, tested, and ready for deployment.
Why me?
- No Regression Issues: Thanks to my testing-first approach, new updates won't break old features.
- Modern Standards: No outdated practices. I use the latest Angular features to keep your app relevant.
- Direct Communication: Clear, technical, and goal-oriented.

FAQ
Which Angular versions do you support?
I specialize in the latest versions of Angular (20, 21+), utilizing modern features like Signals, Standalone Components, and Hydration. However, I am also fully capable of maintaining and upgrading legacy applications.
Why should I pay for Testing?
Testing is an investment, not an extra cost. By writing Unit Tests (Jest/Jasmine), I ensure that future updates won't break existing functionality. This reduces long-term maintenance costs and ensures a bug-free experience for your users.
Which Testing frameworks do you use?
For Unit Testing, I mainly use Jest. But I am also familiar with Jasmine/Karma, which ships with Angular.
Can you work with State Management libraries like NgRx?
Yes. For complex applications, I implement NgRx. For lighter weight state management, I use Angular Signals or RxJS-based services. I choose the tool that best fits your project’s scale to avoid unnecessary complexity.
Can you convert my Figma or Adobe XD design into Angular?
Absolutely. I provide implementation using Tailwind CSS, Angular Material, or Bootstrap. I ensure the UI is fully responsive and accessible across all devices and screen sizes.
Do you handle API integration?
Yes. I have extensive experience connecting Angular frontends to RESTful APIs, GraphQL, and Firebase. I handle authentication, data mapping, and error handling to ensure a seamless data flow.
Will you provide documentation for the code?
Yes. Every project includes a README.md file with clear instructions on how to install dependencies, run the development server, and execute the test suites. The code itself follows Clean Code principles with meaningful naming conventions and comments where necessary.
