// Hello, world

Senior Software Engineer

I design reliable distributed systems and production platforms for healthcare, logistics and data-intensive products.

14+ years shipping production software across Chile, Russia, the Netherlands and Bolivia—from system decomposition and Kafka architectures to cloud infrastructure and customer-facing applications.

Carlos Rojas — Senior Software Engineer
I help engineering teams turn complex systems into reliable products.

My work spans architecture, technical strategy, delivery and mentoring, with hands-on experience in Java, Scala, TypeScript, Kafka, Spring Boot, AWS and Kubernetes. I hold an MSc. in Software Engineering from Innopolis University.

I have led the decomposition of healthcare systems, designed event-driven platforms processing large data volumes, and delivered logistics and telemetry products used in operational environments. I am strongest where technical complexity, business constraints and team execution meet.

Technical ownership

Clarity, context and durable technical decisions.

I work through clarity, context and technical ownership. I help teams understand the problem, contribute to durable architectural decisions and deliver incrementally without losing sight of reliability. I am comfortable moving between system design, implementation, code reviews, incident analysis and mentoring.

Currently: building logistics and telemetry products at Tracktec, exploring AI-assisted development and retrieval-augmented systems, and developing independent products and architecture tools.
