Peter Maquiran
Web, Mobile & Observability Engineer

I'm a Web, Mobile & Observability Engineer with 9 years of experience, focused on building reliable, scalable, and observable systems. I create applications that just work, even in complex environments or with unstable connectivity.

My focus is on Web, Mobile, and Observability, combining hands-on production experience with a full end-to-end systems perspective. I enjoy turning complex systems into simple, efficient, and maintainable solutions, where every metric, log, and trace tells the story of the system.

When it comes to delivering quality, performance, and reliability, I am the right person for the job.
