Computer Systems Design and Integration

Services that keep systems working

Cousin Tytus llc delivers the full lifecycle of computer systems design and computer integrated systems design: architecture, integration, security, and ongoing operations. Everything below is led by the same senior engineers who will operate your systems after launch.

01

Enterprise Architecture Consulting

We start by understanding the systems you already run and the direction the business is heading. We map applications, data flows, and dependencies, then model the target architecture in stages that can be delivered without stopping operations. Every recommendation is costed, sequenced, and documented so leadership can approve with confidence. You receive a roadmap that turns ambition into an executable plan, with the reasoning behind each choice written down for the whole team.

Architecture decisions are recorded as living documents, not dusty artefacts. When your estate changes, the roadmap is updated so it stays the single source of truth for where the systems are going and why.

02

Cloud Migration and Hybrid Platforms

Moving to the cloud is a migration, not a lift and shift. We assess what should move, what should stay, and what should be rebuilt, then sequence the work so risk stays low at every step. We design landing zones that are secure by default and costed honestly, with no surprises in the monthly bill. Where parts of the estate belong on-premise for latency, cost, or compliance reasons, we build a hybrid platform that behaves as one system from the operator point of view.

Our team works with all major cloud providers and remains neutral in the tools we recommend. The destination is decided by your requirements, not by our partnerships.

03

Application and Platform Integration

Your systems were probably not designed to work together, but they must. We build APIs, middleware, and event pipelines that connect applications cleanly and keep data consistent across every handoff. We reconcile differences in formats, schemas, and timing so that every system sees the same truth at the same moment. Each integration is tested for failure modes, not just happy paths, so the platform degrades gracefully instead of breaking loudly.

Whether you are merging two companies, replacing one vendor, or connecting a modern front end to a legacy core, we make the seams invisible and the behaviour predictable.

04

Data Engineering and Systems Automation

Modern operations run on data and automation. We build pipelines that collect, validate, and move data where it needs to go, and we keep the quality high enough that reports can be trusted without manual checks. We automate the repetitive work: provisioning, deployments, backups, monitoring, and reporting. Automation reduces human error and frees your people for the work that needs judgement. Every script and pipeline is versioned, tested, and documented like production software.

The result is an estate that runs itself where it should, with humans stepping in only where a decision is genuinely required.

05

Security and Compliance Engineering

Security is not a feature; it is a property of how the whole system is built and run. We harden networks, systems, and identities, and we design controls that satisfy common compliance frameworks. Access follows least privilege, changes are auditable, and evidence is collected continuously rather than recreated for each audit. Our engineers test the estate for weaknesses and patch before problems become incidents.

We stay current with emerging threats and update the controls that matter, so the security posture of your systems improves over time instead of slowly decaying.

06

Managed Operations and 24-7 Support

After go-live, the work continues. We monitor availability, performance, and security around the clock. We patch, verify backups, and respond to incidents with a 48-hour response SLA and 24-7 coverage. Reporting is plain language: what happened, what it cost, and what we changed. Owners stay informed without needing a technical translator, and engineers keep the estate tuned so problems are prevented rather than discovered by users.

Three service tiers let you choose the level of care that matches your budget, and you can move between tiers as your needs change.

How we work

The engagement path

Every project follows the same disciplined sequence, adapted to the size and urgency of the work.

STEP 01

Discover

A structured workshop and system audit. We document current state, pain points, constraints, and the outcomes the business actually needs.

STEP 02

Design

We produce the target architecture, integration plan, and rollout sequence, costed and staged for approval by the people who pay the bill.

STEP 03

Deliver

Our engineers build, test, and deploy in agreed increments, with you reviewing each release before it moves toward production.

STEP 04

Operate

We run, monitor, secure, and improve the platform after launch, with defined SLAs and honest plain-language reporting.
