Senior Software Engineer
I'm a Senior Software Engineer at Sngular, where I build AI document systems and the cloud platform around them.
Outside work, I co-build Arche and ship open-source tools for agent workflows and macOS, including Moonglade and PodTap.
I also run Magua, an independent web studio in Lanzarote, where I design and build projects such as Tinasoria Apartments.
Python is still my main tool. Lately I've gone deeper into TypeScript, Swift, distributed tracing, agent orchestration, and native macOS systems.

Stack: Python, Gemini, Google ADK, Kafka, MongoDB, OpenTelemetry, Kubernetes, GCP, Terraform.
