Software for public-sector work, built to be maintained.

Merion Systems is a Colorado software engineering company. We build, modernize, and maintain the applications that state and local agencies, federal prime contractors, and nonprofits run on.

The engineer who builds your system is the person you talk to, from the first conversation through delivery and support.

What we do

Most of our work falls into a few areas. Each one is described in more detail on the capabilities page.

All capabilities

Custom software development

Applications built around the way your team actually works.

Backend & API engineering

Services and integrations that let your systems talk to each other.

Application modernization

A path off an aging system without a risky all-at-once rewrite.

Database & data systems

Databases and reporting that make your data usable by the people who need it.

Cloud & DevOps

Infrastructure and deployments your team can run without us.

AI-enabled applications

AI where it solves a specific problem, with a person checking the output.

After launch, we stick around.

We maintain what we build, and we take on existing systems too.

Maintenance and support

How we work

Public-sector software has to keep working long after the project ends, usually for a team that did not build it. That shapes every decision we make.

About Merion

You work with the engineer

There is no account manager between you and the person writing the code. Questions are answered by whoever is doing the work.

Scope is written down first

Before work starts, we agree on what is being built, what it costs, and what finished looks like. When things change, we revisit that agreement together.

Your team can take it over

Documentation, tests, and a handoff are part of every project, so you are never dependent on us to keep things running.

Government contracting and teaming

We work with state and local agencies directly, and as a subcontractor to prime contractors who need engineering capacity. The government page lists our NAICS classifications and current registration status.
