Jose Ignacio Larghi Java/JSF legacy product specialist
I fix and extend Java products that have been in production for years.
Production bugs, builds that no longer run, integrations and bounded improvements on JSF, Seam, RichFaces, PrimeFaces, EJB and Spring codebases. We agree the scope in writing, and your team keeps deployment and production support.
What I take on
- Diagnosing and fixing reproducible production bugs.
- Making an old build reproducible again: containerized, running on a laptop and in CI.
- Repairing or extending an integration, including failure and reconciliation handling.
- Adding a bounded feature or report to an existing product.
How I work
- Scope agreed in writing first: deliverable, acceptance criteria, required access and an hour cap.
- Asynchronous by default. Short calls with an agenda when they help.
- Your team keeps review, deployment and production support. I don't take 24/7 on‑call.
- Every change ships with notes, so anyone on your team can support it afterwards.
Track record
- A US vendor of laboratory software first hired me to fix production bugs in their Java product. Years later they came back to have me build the product's new version, and I still work with them on architecture, implementation and code review.
- Two years as a backend engineer on an internal compliance platform at Indeed, inside a distributed US team, through AgileEngine.
