What I do
-
Backend architecture (Java and Python)
Backend systems in Java/Spring and Python/FastAPI, built on hexagonal architecture and domain-driven design.
-
APIs and integrations
Connecting your systems, third-party APIs and data flows behind clean, tested interfaces.
-
Databases and performance
Data modelling, queries and infrastructure built to keep up as the system grows.
-
Architecture review
An outside, demanding look at an existing system, with concrete, prioritised findings.
-
Applied AI
MCP servers that expose your systems to Claude as typed tools, and Claude setup for development teams.
-
Home automation with Home Assistant
Home Assistant installation and configuration in León and the surrounding area.
How I work
- Fixed price.
- Written scope before work starts.
- One project at a time, so it gets full attention.
