Systems break
where code meets cloud.
That's exactly where I work.

Over a decade building and running systems in production. If your team is shipping faster than your architecture can keep up, that's the work I do.

Get in Touch Services

Sound Familiar?

Why teams
usually call.

It's usually not one mistake. It's a pile of shortcuts from shipping under pressure that now slow down every sprint.

The API keeps growing sideways

More endpoints, messier patterns, slower features. Better to fix the structure now than plan a rewrite.

Nobody really owns the cluster

Kubernetes runs, Terraform exists, but the engineer who built it left and the team won't touch the stack. The same problems keep coming back because root cause never got fixed.

App and infra aren't on the same page

Infra chosen without understanding the app, or code written without thinking about deploys. You want one person who has done both, not two vendors blaming each other.

Application
& Platform.

I write software and run infrastructure. The leverage comes from knowing what each system needs from the foundation, through iteration, into production.

Software Engineering

Messy APIs, missing patterns, or a new project that needs a solid base. Usually we sort out the application before the platform. The goal is a codebase your team can actually move fast in.

  • API design and review (REST, GraphQL)
  • Design patterns: review what's there and what to add
  • Codebase structure and maintainability
  • Web application architecture
  • Documentation and developer experience
  • Engineering process when the team is too big for everyone to know everything

02 · Infrastructure & Platform

Infrastructure & Platform Engineering

AWS, Kubernetes, and Terraform at a senior level when you're not hiring full-time yet. I got into infra because I had to own what happened after deploy, so I don't treat it separately from the code. The goal is infrastructure your team understands and can operate without a hero.

  • Cloud architecture review and roadmap
  • Kubernetes and EKS: setup and day-to-day ops
  • Terraform audit and cleanup
  • AWS costs and security review
  • Platform operations and runbooks
  • Production troubleshooting and root-cause fixes

How It Works

Scope
first.

We nail down what you need on the first call. No pitch deck, no package you have to buy.

01

Discovery

Share your stack, team, and constraints. First call is free, no obligation.

02

Advisory

Reviews, roadmaps, audits. Findings in writing with specific next steps, not vague advice.

03

Hands-on

I join your team on whatever's urgent: pairing, PRs, hands-on implementation.

About Rhei Solutions

Ríoghnach Tate,
founder.

Rhei Solutions is my practice. If you're an engineering leader at a Series A or B company (five to thirty engineers, more features than your infrastructure can handle), you work with me directly: software architecture, cloud infrastructure, or both.

Over a decade in production. I design APIs and systems, run AWS/Kubernetes/Terraform in production, and have led engineering teams through real delivery. Six years in the US Navy before I wrote code for a living. The habits of operating under pressure and owning outcomes stuck.

You get senior judgment without a full-time hire. I'll tell you plainly what I see and what I'd do next. No agency bench, no upsell for work you don't need.
