Jair Carrillo.
Web systems, cloud, and intelligence — with clear limits.
I design and operate digital products, infrastructure, and AI layers. I collaborate with Lunar System X on its public ecosystem, and I keep private runtimes when data must stay local.

02Selected work
Systems I design, build, or operate.
Problem and role first. Stack second.
03Capabilities
Disciplines I connect in one system.
Product, intelligence, cloud, security, and integration are not separate catalogs. They are layers of the same work.
01
Product engineering
From the interface to the system that holds it.
Web software for the people who use it and the people who run it: routes, languages, metadata, and a delivery cycle that can be repeated.
02
AI and automation
Intelligence where it reduces friction, not where it adds it.
Product assistants in exploration, and local runtimes when data must stay private. Connected workflows, with explicit status.
03
Cloud and infrastructure
A base that can change shape.
Architecture, containers, TLS edge, tunnels, and operations. The same contract locally and in public.
04
Identity and security
Perimeter from the design.
Access, headers, loopback, read-only binds, and secrets kept out of the repository. Private material is not published by habit.
05
Integrations
One edge, several systems.
APIs and gateways so products, languages, and tools share an entry point without duplicating infrastructure.
04Approach
Little theater. Contracts you can operate.
I start with a sharp problem cut, a prototype you can touch, and a path to production with observability. Docker is the development and delivery runtime. Status is named: production, development, prototype, or exploration.
Short discovery
What exists, what cannot be claimed, what must be built first.
Product and infra together
SEO, i18n, and the network edge belong in the same design, not at the end.
Explicit limits
Loopback, read-only binds, and deliberate publication.
05About
Engineering with product judgment.
I am a software engineer and platform engineer. I care about the whole system: the interface, the runtime, the edge, and what must not leave the machine. I work with Lunar System X on product and infrastructure; this site and Offline Studio are personal lines of work.
