Jose Beltran

Hi,

I’m a Senior Software Developer with experience building scalable backend systems, fullstack applications, and mobile apps in production environments.

I specialize in Go (Golang), React, and cloud-based architectures (AWS, PostgreSQL, microservices), and also have hands-on experience developing mobile applications using Swift (iOS), Kotlin (Android), and Flutter.

In my current role at KOHO, I work on production-grade financial systems, APIs, and data pipelines where reliability, performance, and clean architecture are critical.

I can help you:

• Build scalable backend services (APIs, microservices)

• Develop fullstack applications (React + backend)

• Build and ship mobile apps (iOS, Android, Flutter)

• Design and implement cloud infrastructure (AWS)

• Debug and optimize complex production systems

I focus on writing clean, maintainable code and delivering fast, reliable results.

Happy to discuss your project and get started quickly.
