Alexander Viafara

Systems Engineer

Turning ideas into great results — Code. Create. Conquer.

About

I’m a systems engineer passionate about building reliable and scalable backend systems, where solid engineering meets thoughtful design. In the last year, I’ve transformed complex problems into elegant solutions, turning business rules into clean architectures and well-structured APIs that enhance the overall product experience.

Although my specialty is backend development and modern architectures, I also have practical experience with Angular and React. This allows me to create smooth integrations and ensure that backend and frontend communicate with precision and consistency, maintaining a complete view of the product.

I have a growing interest in how artificial intelligence can enhance backend services through automation, intelligent analysis, and process optimization, integrating it in a practical way when it brings real value.

Beyond coding, I channel my passion for design into personal projects, such as building my personal brand identity and exploring UI/UX principles from a developer’s perspective. I actively participate in tech communities because I firmly believe that collaborative learning drives innovation.

When I’m not programming, you’ll find me playing as a creative midfielder in weekend soccer matches, enjoying video games like Call of Duty: Warzone and EA Sports FC, or traveling to experience new cultures and search for the world’s best empanadas.

I’m at my best in teams where curiosity drives progress. Let’s build solutions that not only work—but inspire.

Experience

JUL — DEC 2024
Trainee Architect Developer • Ceiba Software
Designed and implemented end-to-end solutions using Angular and ASP.NET Core, optimizing internal processes by 10%. Additionally, I developed RESTful APIs that reduced response times by 8-10%, enhancing system efficiency. I applied design patterns (CQRS, MVC, Repository) to simplify maintenance and scalability, cutting support efforts by 10-15%. Through active participation in agile teams, I conducted code reviews and contributed to architecture definitions, strengthening team cohesion and elevating product quality.
