01 / CAPABILITIES

Software and infrastructure,
considered together.

Software engineering

Purpose-built utilities and applications for practical operational needs. Our interests include command-line tools, data movement, and integration between established and modern systems.

Systems integration

Connecting platforms through well-defined interfaces and repeatable workflows. We focus on understanding system boundaries, data formats, and the requirements of each environment.

Infrastructure automation

Documented provisioning, configuration, and verification processes. Repeatable builds help make environments easier to understand, maintain, and recover.

DEVELOPMENT PROJECT

ZenoCopy

ZenoCopy is a software project under active development for file transfer and host interaction in CMS environments. Development focuses on native CMS behavior, transfer integrity, recovery, and integration with Linux tooling.

We use controlled development environments and documented acceptance checks to investigate system behavior and validate changes. Availability and supported configurations will be defined as qualification progresses.

02 / TECHNICAL FOCUS

Working across generations
of technology.

Mainframe & CMS environments

Development and integration work involving z/VM and CMS, with particular interest in file transfer, host communication, and operational tooling.

Linux & virtual infrastructure

Linux services and virtual machine environments provide a foundation for development, testing, and integration with other platforms.

Interoperability & data movement

Reliable integration starts with explicit assumptions about bytes, records, encodings, and system behavior. We emphasize controlled testing and clear evidence.

03 / OUR APPROACH

Understand. Build. Verify.

  1. Define the outcome

    Start with the actual requirement, the system constraints, and a clear way to measure success.

  2. Keep changes focused

    Use bounded experiments and make the smallest change supported by the evidence.

  3. Document the result

    Preserve the implementation details, verification results, and known limitations.

04 / ABOUT ARILLY

Independent by design.

Arilly International LLC is an independent company based in Carlsbad, California. Our technical work centers on software, systems, and the connections between them.

We value direct communication, careful investigation, and engineering decisions grounded in observable results.
