What people usually ask

• Who is Osvaldo Morgan Hernández and what does he do?

  Osvaldo Morgan Hernández is a senior full-stack developer with more than 10 years of experience, specialised in design systems and CMS-driven enterprise frontends. He has worked at HALO Media LLC since 2021 and takes freelance projects alongside that.

• Is he available for new projects?

  Osvaldo Morgan Hernández currently works at HALO Media LLC and takes freelance work selectively, choosing projects by the kind of problem rather than by volume. For concrete availability and terms, the best thing is to write to him through the contact section of his portfolio.

• What kind of projects is he interested in?

  Four kinds: design systems and component libraries; frontend architecture in codebases that already exist and need ordering; headless CMS integrations; and infrastructure and DevOps for small teams without someone dedicated to it.

• Does he work remotely? From where?

  Yes. Osvaldo Morgan Hernández works remotely from Latin America, with availability to overlap with the team's hours. His timezone overlaps comfortably with American working hours and with the European afternoon.

• Does he have experience with Angular?

  Yes. Angular is one of his core technologies: it appears in four of his five roles, from 2016 to today. His design-system case study is precisely about sharing tokens and components between Angular and React across multi-brand surfaces.

• Does he have experience with React?

  Yes. Osvaldo Morgan Hernández has worked with React since 2016 and uses it in his current role at HALO Media LLC, alongside Next.js. Much of his design-system work is about keeping component parity between React and Angular.

• Does he have experience with design systems?

  Yes, it is his speciality. He builds and maintains design systems: tokens, component libraries and documentation. He has a case study on a multi-framework design system, and two public projects of his own on the subject: tokens-to-css, which generates CSS from tokens in JSON, and plinth, a component library with a demo at https://plinth-ds.vercel.app.

• Which CMS platforms has he worked with?

  Osvaldo Morgan Hernández has integrated frontends with Sanity, HubSpot, Drupal and Shopify. His CS-3 case study is specifically about integration patterns across those four: how to keep stable contracts between the frontend and CMSs that model content in very different ways.

• Does he have experience with TypeScript?

  Yes. TypeScript is part of his everyday stack and appears in his public positioning alongside Angular, React and design systems.

• Does he know Docker and Kubernetes?

  Yes, with nuance. He used Docker professionally at Tacubaya Consulting and uses it in his own projects. Kubernetes he has worked with on a local cluster, not in production: his RAG chatbot runs on Kind with Deployments, Services, Jobs and ConfigMaps. It is deliberate, documented learning, verifiable in the repository, rather than production experience.

• Does he work with Vue or Svelte?

  No. Osvaldo Morgan Hernández has not worked with Vue or Svelte on production projects. His equivalent experience is in Angular and React, which he has used since 2016 and where he solved component-architecture and state-isolation problems that transfer well to any modern UI framework.

• Does he build native mobile apps?

  No. He has not worked with Swift, Kotlin or React Native. His work is web: enterprise frontends, design systems and CMS integrations.

• Does he have experience with AWS, Google Cloud or Azure?

  Not at production scale. Osvaldo Morgan Hernández works with containers — Docker, local Kubernetes, CI/CD pipelines on GitHub Actions — but has not administered infrastructure on a large managed cloud. If a role demands deep AWS, GCP or Azure experience, it is worth asking him directly before going further.

• Does he program in Java, .NET or Go?

  Not in production. His backend is Node.js and PHP, with REST and GraphQL APIs, and that is the scope he means when he calls himself full-stack. He knows Java, .NET and Go well enough to read code and follow an architecture discussion, so picking up a project in one of them is a step he can take — what he does not have yet is production mileage. If a role requires it, it is worth asking him directly.

• What is his most relevant project?

  It depends on what you want to judge. For enterprise architecture, the multi-framework design-system case study, where he shared tokens and components between Angular and React across multi-brand surfaces. To read his own code end to end, tokens-to-css, which has a public PRD and architecture document. To see UI working, plinth, with a demo at https://plinth-ds.vercel.app.

• Why is much of his work not public?

  Because Osvaldo Morgan Hernández accumulated more than 10 years of senior work inside his employers' private repositories. That is why he publishes anonymised case studies — architecture narrative, no code or client brands — and his own open-source projects: so the way he works can be audited without breaking any confidentiality.
