Government software that has to work for everyone, for years.
Citizen and government platforms carry a different weight: they have to be usable by every person regardless of device or ability, accountable to the public, and maintainable long after the team that built them moves on. We build to that standard.
What makes public-sector software genuinely hard.
It isn't the features. It's that the bar for access, accountability, and longevity is set higher than almost anywhere else, and “most users” is never good enough when the user is every citizen.
Every citizen, every device, every ability
A public service can't choose its users. It has to work on an old phone, over slow data, with a screen reader, in plain language, and often in more than one language. Accessibility is a legal obligation and a moral one, not a polish pass.
Accountability is on the public record
Decisions have to be explainable, actions have to be logged, and records are subject to FOIA and audit. The system isn't just used by the public, it answers to them.
Service lifetimes measured in decades
What ships this year may still be running in fifteen. That rewards boring, well-documented, standards-based engineering a future team can pick up, and punishes clever, undocumented, vendor-locked shortcuts.
Legacy systems and procurement reality
New services rarely start from a blank page. They integrate with aging systems of record and ship inside real procurement and funding constraints, which means phased, demoable delivery, not a big-bang launch.
Security and public trust are the same thing
Citizen data is sensitive and the threat is real. A breach isn't just an incident, it's a headline and an erosion of the trust the service depends on. Security and privacy have to be designed in and provable.
The systems citizen services run on.
These are the platform types we engineer, the same building blocks a modern public service is assembled from.
Citizen-facing digital services
Apply, renew, report, and pay flows that meet people where they are, accessible, mobile-first, and written in plain language.
Benefits & eligibility systems
Rules-driven eligibility, application processing, and case management with the audit trail decisions require.
Identity, login & access
Secure sign-in and verification that balances fraud prevention with not locking out the people who need the service most.
Caseworker & admin tools
Internal platforms that let staff resolve cases quickly, with the controls and logging that accountability demands.
Public information platforms
Content and open-data sites engineered for resilience under traffic spikes and for radical accessibility.
Legacy integration layers
APIs and middleware that modernize the experience while the systems of record keep doing their job underneath.
We build to the bar, and evidence it.
These are the frameworks public services answer to. We treat them as architecture inputs from day one and produce the documentation your accessibility, security, and audit reviewers expect.
Review our approach with your team →We engineer the systems we build to meet these standards’ controls and produce the supporting evidence; Paragon does not claim to hold these certifications itself.
Designed for access, built to last.
Map the service, the users, and the obligations
We learn how the service actually works, who depends on it (including the hardest-to-reach), and the accessibility, privacy, and records rules it carries, before proposing a solution.
Test with real people and assistive tech
Accessibility and plain language are validated with actual users, screen readers, and keyboard-only flows, not assumed and signed off at the end.
Ship demoable increments within procurement
Standards-based, well-documented code delivered in milestones you can fund, review, and put in front of stakeholders, with legacy integration de-risked early.
Build it so your team can run it for a decade
Runbooks, architecture decision records, and knowledge transfer mean the service outlives the engagement, owned by you, on open standards, with no lock-in.
What we bring to your public-sector build.
Senior engineers, a discovery-led start, and the disciplines these systems live or die on, accessibility, auditability, security, and longevity, brought to your service from the first sprint.
The hard parts transfer directly
Accessible interfaces, immutable audit trails, high uptime, and integration with stubborn legacy systems aren't unique to government, they're the problems we engineer for every day. We bring that proven discipline to your service.
We get fluent before we build
Every engagement opens with structured discovery alongside your domain experts. We learn your rules, constraints, and users in depth before a line of production code is written.
We adopt your standards, and prove them
We build to WCAG, Section 508, and your security framework, and produce the evidence your reviewers need. You're not taking our word for it, you're getting documentation.
You own all of it
Code in your repositories, infrastructure in your accounts, open standards throughout. If the partnership ends, the service doesn't, and no vendor is holding it hostage.
What public-sector teams ask us first.
How do you get up to speed on a domain like ours?
We open with structured discovery alongside your team to get fluent in your service, its users, and its obligations, then bring the engineering disciplines these systems demand: accessibility, auditability, security, and long-term maintainability.
Can you meet WCAG 2.2 AA and Section 508?
Yes. Accessibility is built in and tested with assistive technology throughout, not retrofitted, and we provide conformance documentation for your reviewers.
Will the service survive after the engagement ends?
That's a design goal, not an afterthought. We use open standards, document decisions, and run knowledge-transfer sessions so your team can own and extend it for years.
Can you integrate with our existing legacy systems?
Yes, most modernization wraps around systems of record we don't replace. We build integration layers and de-risk them early, before they can derail a timeline.
How do you work within procurement and phased funding?
We scope milestone-based delivery you can fund and review incrementally, with something demoable early, so value and accountability are visible at every stage.
Have a public service to build or modernize? Let's talk.
Tell us about the service and who it has to serve. We'll bring a discovery-led plan, an accessibility-first approach, and a team accountable through launch and handover.
