Fitzroy · Software & AI Engineering
We build the systems behind the business.
Backend platforms, cloud infrastructure, and applied AI—engineered for production.
Engineering
Engineering for systems that have to work.
Fitzroy works with engineering and operations teams to turn difficult technical work into software that runs, integrates, and can be maintained.
Robotics & Physical AI
Engineer the path from simulation.
Develop simulation and robot-learning systems for scoped research and engineering programs, backed by inspectable public work.
Explore
Production AI
Put AI inside a working system.
Connect models to real data and workflows with evaluation, permissions, human review, and operational monitoring.
Explore
Cloud Infrastructure
Build for reliable operation.
Implement deployment paths, observability, and infrastructure controls for reliable releases and clearer cost ownership.
Explore
Backend Systems
Modernize core systems.
Refactor services, build APIs, repair integrations, and improve the reliability of software your operations depend on.

Before the larger build
Start with a defined diagnostic.
Fitzroy clarifies the technical question, examines the evidence, and defines scope and deliverables before implementation.

Industrial bid-operations software that structures RFQs, clarifications, ownership, issues, and submission readiness around the real workflow.
Cloud economics
Find the value hidden inside your cloud spend.
Respondents to Flexera’s 2026 State of the Cloud survey estimate 29% wasted IaaS/PaaS spend. That supports investigating efficiency—not promising a fixed saving.
Our separate illustrative scenario assumes $500K monthly spend, a 25% achievable reduction, and $250K one-time implementation cost. The figures below are modeled, not measured client outcomes or research-validated returns.
$1.5M
Modeled annual gross savings
$1.25M
Modeled first-year value
2.0 mo
Modeled payback period
Assumes immediate, full-year savings; excludes added recurring costs and ramp-up. Actual savings require workload and billing validation.

Before scaling AI, know what production will demand.
Fitzroy’s AI Production Readiness Checklist helps leadership teams evaluate production infrastructure, data paths, integrations, controls, governance, and ownership before AI leaves the pilot stage.
Infrastructure and deployment readiness
Data, workflow, and integration dependencies
Governance, controls, and operating ownership
A clearer path from pilot to production
Delivery model
A defined build, delivered with your team.
We agree on the system boundary and operating constraints, build in reviewable increments, and hand over code and documentation your team can use.
How we work01
Scope
Define the system boundary, constraints, acceptance criteria, and first deliverable.
02
Design
Map services, data, dependencies, failure paths, and security boundaries.
03
Build
Implement code, infrastructure, integrations, and tests in reviewable increments.
04
Release
Verify deployment, observability, permissions, rollback, and operational ownership.
05
Improve
Measure behavior, address defects, and iterate with the team.

Why Modern Backend Systems Matter More Than New Software
Adding new software does not always create more value. The systems, data, and architecture underneath may determine what technology can actually deliver.
