[ About JFX ]

Precision engineering, two continents

We are a software house built around senior engineers, rigorous architecture and delivery discipline. No hand-offs to juniors, no black boxes: you get the same team from discovery to production.

Operating from Europe and Brazil, we cover overlapping time zones, GDPR/LGPD-aware processes and multilingual squads embedded directly with your product team.

Senior by default

Every squad is led by engineers with 10+ years in production systems.

Best practices, enforced

Code review, CI/CD, automated tests and observability from day one.

Business-first

We optimise for your metrics, not for lines of code.

What technology leaders say

JFX took over an architecture nobody wanted to touch and made it boring — in the best possible way. Deploys are now a non-event.
MFMarta FerreiraCTO, Atlas Logistics · Portugal
They behave like an internal team, not a vendor. The level of technical seniority in every conversation is rare.
RMRodrigo MenezesHead of Product, Nexus · Brazil
Clear estimates, clear trade-offs, delivered on the dates they committed to. That alone puts them ahead.
JRJulien RocheCIO, Helix Industries · France
Our reporting went from a monthly fire drill to something the board actually trusts.
AWAnna WeberData Director, Orion Retail · Germany

Frequently asked questions

With a paid discovery of one to three weeks. We map goals, constraints and risks, then deliver an architecture proposal, scope slices and a realistic estimate. You own everything produced, even if you stop there.

Fixed-scope projects, dedicated squads with a monthly rate, and staff augmentation for specific roles. Most clients start fixed-scope and move to a dedicated squad once the roadmap grows.

A focused MVP usually reaches production in 8 to 14 weeks. Larger platform work runs in quarterly roadmaps with production releases every sprint.

You do, entirely. Repositories live in your organisation from the first commit, and all infrastructure runs on accounts you control.

We offer support contracts with defined SLAs, monitoring, security patching and an evolution roadmap. Many clients keep a reduced squad for continuous improvement.

Yes. We regularly embed with in-house teams, adopt your rituals and tooling, and contribute to shared repositories with the same review standards.
