XRiley · Powered by DXR

Engineering systems that cannot be allowed to fail.

As a Fractional CTO and principal engineer, XRiley guides organizations through technical direction, architectural clarity, and delivery discipline. Beyond executive leadership, we build and modernize the systems businesses depend on most—from financial platforms and payments to property tax, regulatory systems, CMS at scale, and deep internal and external integrations. Whether leading your team or engineering the platform itself, XRiley delivers architecture-first systems designed to stay correct under pressure.

DXR Signature — The XRiley Engineering Standard

DXR is the engineering methodology that defines XRiley’s work — a standard of resilience, precision, and architectural clarity that every system must meet, without exception.

Interfaces are explicit. Failure modes are intentional. Operational paths are rehearsed before production. DXR ensures every system bearing its mark is engineered to stay correct under pressure.

Architecture that can be reasoned about under load.
Failure modes designed before the happy path ships.
Operational discipline that respects production, not slideware.
Systems engineered to remain correct under pressure.

Verticals

The XRiley engineering surface.

Four verticals that cover architecture, leadership, integration, and the hard work of shipping.

Forge · Architecture & Platform

Design the backbone: cloud, data, and services shaped for longevity, not novelty.

We shape systems that can grow without collapsing under their own weight: clear boundaries, explicit contracts, and observability from day one.

Armature · Strategy & Leadership

Fractional CTO support and staff-plus engineering guidance for teams that need a sharper technical center.

We work with leadership to align architecture, headcount, and delivery so teams can move without burning correctness.

Alloy · Integrations & APIs

Microservices, API ecosystems, and integrations that hold up under real-world cross-system complexity.

From partner APIs to internal meshes, we design interfaces and failure handling so integrations are predictable, not brittle.

Rivet · Delivery & Modernization

Refactors, replatforms, and greenfield delivery carried all the way to production.

We take responsibility for shipping: migration plans, rollout strategies, and controlled change management in live systems.

XRiley Foundry · Long-lived software, delivered.

Foundry is how XRiley takes ownership of delivery from architecture to rollout.

We design the system, write the code, and stay with it through launch and early operation.

Senior engineers only.
Architecture, implementation, and handover.
Structured around reliability, not feature count.

XRiley Guild · Raising the engineering floor.

Guild exists for engineers who want deeper discipline and rigorous, unfiltered review.

Mentorship grounded in incident reviews, long-lived systems, and the work of running real software in production.

Patterns tested against real failure modes.
Support for tech leads and staff engineers under load.
Cohorts and 1:1 guidance tuned to your systems.

Fit

Where XRiley fits.

We work with teams who already care about rigor and need a partner who can match it.

Platforms carrying financial, operational, or safety-critical risk.

Systems under growing load or complexity that need a stronger backbone.

Teams that need an external senior partner, not a disposable vendor.

If failure isn't an option, the architecture can't be casual.

If you're responsible for systems that must stay correct under pressure, we should talk.
