Consulting & Freelance

Engineering that moves your business forward

I'm Julio, a software engineer specialised in Supabase, Next.js & React. I help startups and enterprise teams design, build and ship reliable web products, from greenfield apps to migrations and CI/CD.

How I can help

Flexible engagements: project-based, ongoing, or a one-off consultation. Pick what fits.

Product & Web App Development

End-to-end web applications built on my core stack: Next.js, React and Supabase. From the first line of schema to a fast, SEO-ready product in production.

Enterprise Frontend Engineering

Large-scale, maintainable frontends for teams and internal tooling, not just consumer products. Comfortable inside established enterprise codebases and design systems.

Backend & APIs

Robust APIs and services to power your product. From Supabase/Postgres data models to Java and Spring Boot services for heavier enterprise workloads.

CI/CD & DevOps

Automated pipelines so shipping is boring and safe. Build, test and deploy on every push with GitHub Actions and Docker, plus environment and release hygiene.

Migrations & Modernisation

Moving legacy or hard-to-maintain sites onto a modern stack without losing SEO or content. Exactly what I did migrating a live client site to Next.js + Supabase.

Technical Consulting

A second pair of eyes on architecture, stack choices, performance or SEO. Short engagements to unblock your team and de-risk the next decision.

Why work with me

  • Real, shipped client work. I rebuilt and migrated a live client website to Next.js + Supabase, improving SEO, admin workflows and day-to-day operations.
  • Enterprise experience, not just demos. I've worked across large codebases and internal tooling with Angular, Java and Spring, so I'm comfortable in serious, long-lived systems.
  • You talk to the person doing the work. No account managers, no hand-offs. Direct communication from first call to delivery.
