I will build your angular spa or microfrontend application
Marlon A
About this gig
Most Angular developers deliver a working UI. Few deliver one that's tested, scalable, and ready for a production banking environment.
I'm a Senior Full Stack Developer with 7+ years building Angular SPAs and micro-frontends for banking clients, including Bancolombia, Banistmo, and Ticketmaster. I bring that same engineering discipline to your project.
What you get:
- Angular 19 SPAs or micro-frontends, modular, scalable architecture
- Reactive state management with RxJS and NgRx, where needed
- REST API integration with Spring Boot or Node.js backends
- Unit tests with Jest, Jasmine, and Karma coverage reports included
- SonarQube-clean code, no shortcuts on quality
- OAuth2 / Azure AD authentication integration
- Responsive UI with Angular Material or your preferred component library
- Full documentation and handoff
This is a great fit if you need:
- A frontend built to enterprise standards, not just tutorial quality
- An existing Angular app refactored, upgraded, or extended
- A micro-frontend integrated into a larger platform}

Yes. Send me your repository and a description of what you need. I'll review it and give you an honest assessment before you order.

Primarily Java Spring Boot and Node.js REST APIs, but I can integrate with any well-documented API. GraphQL integration is also available — message me to discuss.

Yes, all packages include unit tests with Jest and Karma. Standard and Premium include full coverage reports. Testing is part of the deliverable, not optional.
