hey, I’m Guada.
I build backend systems, integrations, and internal tools for SaaS products. I’m currently learning more about system design and AI-assisted workflows.
↗ MY MISSION
Build software that supports people’s everyday work and has room to evolve.
About me.
I work across backend and frontend, but backend is where I feel most at home. I define APIs, model data, integrate external services, and build interfaces and internal tools that support teams day to day.
Most of my backend interest is in background jobs, queues and retries, observability, authentication, and clear service boundaries.
On a normal workday I use AI agents, MCP servers, and coding assistants for research, prototyping, and routine development tasks. I’m interested in how they fit into real product workflows.
Experience.
