About

My name is Roberto Heckers, a freelance software engineer from the Netherlands specializing in Angular and Nx for the front-end and .NET in the backend. As a software engineer, I've developed many exciting applications, including consumer-facing, B2B, and manufacturing applications, that have generated millions in sales and business value for my employers and customers. For many of these applications, I focused on complex data visualization, performance, scalability, and facilitating actionable interfaces with accessibility and security in mind. I developed extensive enterprise backend systems with very high throughput and workloads and crafted front-end systems that are used in production by millions of users. I'm well-known as a subject matter expert and content creator in the Angular community. I'm the author of Effective Angular (published by Packt), create daily posts on LinkedIn for my 14K+ followers, was one of the main speakers at Ng Poland 2024, was a guest on Angular podcasts and I blog on websites like angularspace.com. Currently, I'm active as a freelance software engineer and consultant. As a freelancer, I can help you with: - Developing entire applications - Working together with your team for an extended period - Do code analysis on Angular projects to identify bottlenecks - Setup a good architecture (especially for Nx and Angular projects) - Do performance optimizations - Give Angular + Nx workshops

  • Assignment from System 4.
