About Me

Teofilo Callanaupa

Teofilo Callanaupa

I’m a full-stack software engineer focused on building reliable, production-ready systems, including AI-powered applications and data-driven platforms.

I’ve worked across startups and large-scale environments, designing and shipping features that span frontend, backend, data pipelines, and testing infrastructure. I enjoy tackling ambiguous problems, improving system reliability, and translating real-world requirements into maintainable software.

Outside of coding, I’m an avid rock climber. I'm drawn to the same mix of problem-solving, iteration, and persistence that keeps me engaged in engineering.
