Scouting report

Backend/mobile generalist with a cloud-IoT master's thesis

assessed from open-source footprint

Junior
39signal

Luis spreads across backend, mobile, frontend, and DevOps in roughly even measure, working in Kotlin, TypeScript, and Docker. The most substantive artifact is a master's thesis project designing a cloud analytics architecture for an IoT application, alongside a Dockerized WordPress dev environment. Despite a nearly nine-year account, the public output is modest — six original repos, no stars, light recent activity, and low polish. The read is a credentialed generalist with graduate-level systems exposure but a sparse, under-documented public portfolio. Substance is implied more than demonstrated.
