Design, Integration, and Assurance for the Systems You Run On
Every service we offer falls under computer systems design and computer integrated systems design. We take a system from an idea on a whiteboard to a machine that runs your business every single day, and we stay involved long enough to prove that it works. Each engagement is scoped, priced, and governed around a clear outcome, so you always know what you are paying for and why it matters.
Computer Systems Design
We design computer systems from the ground up, starting with the requirements that actually shape your work. Our team defines the architecture, selects the components, and documents every interface before anything is built, so that the system you approve is the system you receive. The design phase covers hardware, software, networks, security boundaries, and the way each piece will behave under real workloads.
A well designed system reduces the cost of change for years. We model failure modes, capacity ceilings, and recovery paths as part of the design itself, which means most problems are solved on paper at a fraction of the cost of solving them in production.
Computer Integrated Systems Design
Computer integrated systems design is the discipline of making separate systems behave like one system. We connect hardware, software, devices, and data sources into a single operating whole, and we engineer the interfaces so that information flows without manual repair work. Integration is where most projects fail, and it is where we concentrate our attention.
We build and test the seams between systems first, not last. Every message, every handshake, and every error path is specified and verified, so that the finished estate works as a coherent machine rather than a collection of well meaning parts.
Cloud and Infrastructure Modernization
Many organizations are running capable systems on infrastructure that no longer fits their size. We plan and execute migrations to modern platforms with a sequencing that protects your operation at every step. Hybrid estates are our home ground: we decide deliberately what stays local, what moves, and what the connection between them must guarantee.
Modernization is a design problem, not a copying exercise. We re-architect for the new environment, rightsize capacity, and put resilience into the platform so that the move improves reliability rather than merely relocating it.
Data Integration and Interoperability
Data that cannot move is data that cannot decide. We build the pipes that carry information between your systems: application interfaces, message streams, batch exchanges, and the governance that keeps them honest. Our integration designs treat data quality as a first class concern, because a connected system that delivers bad data is worse than two isolated systems.
We document schemas, ownership, and refresh expectations for every flow we build. When a downstream system breaks, your team will know exactly where the fault sits and what the recovery looks like.
Legacy Systems Rehabilitation
Not every system needs to be replaced, and many should not be. We rehabilitate aging systems by modernizing the parts that hurt you most: fragile integrations, manual workflows, unpatched security gaps, and interfaces that only one person understands. Rehabilitation extends the useful life of a system without the risk of a disruptive rebuild.
We approach each legacy estate with respect for what it does well. The goal is to remove the expensive fragility while preserving the behavior your operation depends on, and to do it in small, verifiable increments.
Systems Assurance and Validation
Assurance is how we prove that a system does what it was designed to do. We plan and run validation programs covering functional behavior, integration, performance, security controls, and the acceptance criteria your contract requires. Every finding is traceable to a requirement, so the evidence is usable by your auditors and your leadership.
We design the test strategy as early as the architecture, which means assurance is never an afterthought. By the time a system reaches go live, its behavior has been demonstrated, not assumed.
One Process, Applied With Discipline
Every engagement at PKMG LLC follows the same five-stage process. The stages adapt to the size of the work, but the discipline does not. This is the machine that builds machines.
Discover
We learn your operation, your constraints, and the outcome you actually need.
Design
We produce a precise architecture with every interface and control specified.
Build
We implement in small increments, keeping the system usable at every step.
Verify
We validate behavior, performance, and compliance against written criteria.
Handover
We deliver documentation and operating knowledge your team can own.
