Custom Software Development

We build the software your business runs on.

Senior engineers design, build, and ship production systems across SaaS, cloud infrastructure, and AI. A named engineer signs off on every build.

Why most builds fail

The code was never the hard part. The judgment was.

A model will write you a function in a second. It will not tell you the data model is wrong, that the retry storm will take down your database at 3am, or that the feature you asked for is the wrong feature. Someone has to own those calls and answer for them.

01

Agencies hand you juniors

You meet the senior on the sales call and never see them again. The build goes to whoever is on the bench, and you inherit their shortcuts.

02

Generated code looks right

It works on the happy path and fails on the worst day. The bugs are not typos, they are architecture, and they surface once you have real customers.

03

Nobody signs their name

When it breaks, everyone points somewhere else. No engineer staked their reputation on the thing that shipped.

What we build

Systems that carry real operations.

Not brochureware. Software where downtime and errors cost real money.

01

SaaS platforms

Multi-tenant products with real auth, billing, roles, and data isolation. Built so your first thousand paying customers do not find the seams.

02

Cloud infrastructure

Distributed systems, APIs, data pipelines, and Kubernetes workloads designed to hold up under load and stay affordable as they grow.

03

AI and agentic systems

LLM features, RAG pipelines, and agent workflows with the guardrails, evaluation, and fallbacks that keep them from embarrassing you in production.

The math

One senior hire costs more than most builds.

A senior engineer in the US runs $180,000 to $250,000 a year fully loaded, and you carry the recruiting risk, the ramp, and the bad-hire risk on top. An engagement gives you a senior team for the length of the work, and nothing after it.

How we engage

Three shapes. You pick the fit.

Every engagement is scoped and priced in writing before a line of code is written.

Fixed-Scope Build

For a defined product with a deadline.
Quoted
  • One agreed price and timeline, fixed before we start
  • Architecture, build, tests, CI, and a production deploy
  • A named senior engineer signs off on what ships
Scope a build
Most common

Embedded Team

For when you need senior capacity, now.
Monthly
  • Senior engineers who join your team and ship alongside it
  • Your standups, your board, your codebase
  • Scale up or down monthly. No recruiting, no ramp

Fractional & Advisory

For when you need judgment, not hands.
Retainer
  • Architecture review and technical due diligence
  • Fractional engineering leadership for a team without one
  • A senior voice in the room when the call is expensive
Talk to us

Development is quoted, not listed. The scope decides the number, and you see it in writing before we start. Already built something and just need it reviewed, launched, or run? See full pricing.

Tell us the hardest problem you have.

Not a sales call. A senior engineer reads it and tells you honestly whether we are the right people for it.

Why Rydeum

Engineering judgment, not just output.

01

Seniors do the work

The engineer on the call is the engineer on the code. No bait and switch, no bench juniors.

02

Someone signs it

A named senior engineer stands behind every build. When it matters, there is a person, not a process.

03

You own all of it

Every repository, cloud account, and line of code is yours. We do not hold your product hostage.

Who does the work

Senior specialists vetted through the top 3% of a global talent network: Node and NestJS, Go, Python, Kubernetes, React, Angular, and React Native, with real production scars. Based in the Atlanta metropolitan area, working with clients across the United States.

FAQ

Questions, answered.

It depends entirely on scope, so we will not pretend otherwise with a fake number. What we will do is scope it properly and give you one fixed price in writing before any work starts. Our productized services (code review, deployment, managed infrastructure) do have listed prices.

Our engineers use whatever makes them faster, including AI. The difference is that a senior engineer reviews, owns, and signs off on every line that ships. Generation is cheap. Judgment is what you are paying for.

Yes, and it is common. We usually start with a code review so we both know exactly what we are inheriting before anyone commits to a number.

You do, from day one. Every repository and cloud account is in your name. There is no lock-in and no hostage-taking.

Your choice. We hand it over cleanly and walk away, or we keep running it for you under managed infrastructure. Both are fine. Neither is a condition of the other.

A senior engineer reads every message and answers honestly, including when the answer is that you do not need us. No sales call to start.
