[ FEDERAL SOFTWARE ] // CUSTOM DEVELOPMENT FOR GOVERNMENT

Custom software for federal agencies, built by an SDVOSB that has shipped through ATO.

We design to FedRAMP Moderate, NIST 800-53 Rev 5, and Section 508 from sprint one — on AWS GovCloud, Azure Government, or as a sub under your existing prime on SeaPort-NxG, OASIS+, or CIO-SP3.

Veteran-Owned SDVOSB
[001 / 005] Field Conditions

Most federal software projects fail the ATO, not the build.

// SITUATION

The pattern is predictable. A contractor wins the award, builds working software in 6 months, then spends another 12 months retrofitting NIST 800-53 controls, writing the SSP from memory, and patching Section 508 violations the design system never accommodated. The AO sends the package back twice. The PM rotates. The ceiling gets eaten by modifications. By the time the system reaches production, half the original requirements are stale and the next recompete is already on the calendar. The software wasn't the problem — the sequencing was.

  • SSP and POA&M get drafted in the final two months instead of co-evolving with the codebase from sprint one.
  • Section 508 violations baked into the component library require a near-total UI rewrite to remediate before launch.
  • Vendor builds in commercial AWS, then discovers the data is CUI and the entire boundary needs to migrate to GovCloud.
  • Audit logging is an afterthought, so the system can't satisfy records management, FOIA, or AU-family controls at assessment.

[002 / 005] Operational Approach

Build to ATO from day one, not as a retrofit at the end.

  1. STEP-01

    Map the procurement lane first

    Before writing code, we confirm the vehicle: SDVOSB sole-source under $9M, 8(a) partnership, GSA MAS, or sub to a prime on SeaPort-NxG, GSA OASIS+, or CIO-SP3. The contracting path determines architecture constraints, reporting cadence, and acceptable subcontractor mix.

  2. STEP-02

    Pick the boundary before the stack

    FedRAMP Moderate via AWS GovCloud or Azure Government is the default for most CUI workloads. We document the SSP control inheritance early — typically 250+ of the 325 NIST 800-53 Rev 5 Moderate controls inherit from the CSP, and we write the rest into the build.

  3. STEP-03

    Ship in 2-week increments against a POA&M

    Federal sponsors expect demos, not slideware. We run two-week sprints with a working build deployed to a dev enclave, paired with a live POA&M tracking control implementation status. ATO packages get assembled continuously, not in a six-month sprint at the end.

  4. STEP-04

    Bake in 508 and audit logging

    Section 508 conformance (WCAG 2.1 AA) gets verified each sprint with axe-core in CI plus manual JAWS/NVDA passes on critical flows. Audit logs ship to a tamper-evident store — typically CloudWatch Logs with S3 Object Lock or Splunk — with retention matching the records schedule.

  5. STEP-05

    Hand off with documentation that survives

    Government PMs rotate. We deliver an SSP, ATO artifacts, runbooks, IaC (Terraform/CloudFormation), and a 90-day transition plan so the next contractor or in-house team can operate the system without a knowledge cliff.

Compliance gates run in CI on every PR — 508, SAST, SBOM, and NIST control checks fail the build, so the ATO package is always current.

[003 / 005] Common Questions

Field FAQ.

Are you SDVOSB-certified, and what does that mean for my contracting officer?

Yes. VooStack is certified as a Service-Disabled Veteran-Owned Small Business through the SBA's Veteran Small Business Certification (VetCert) program. That makes us eligible for SDVOSB set-asides, sole-source awards up to $9M for non-manufacturing services under FAR 19.14, and counts toward your agency's 5% SDVOSB goal. We can provide our certification letter, SAM.gov registration, UEI, and CAGE code for your file the same day you ask.

Can you actually deliver an ATO, or do you just build the software?

We build the software and produce the artifacts the AO needs to issue an ATO — SSP, POA&M, contingency plan, incident response plan, and the body of evidence for each control. We don't sign the ATO; only the agency's Authorizing Official does that. But we've shipped systems where the ATO landed on schedule because the package was assembled continuously during the build, not bolted on after.

How long does it realistically take to get a system to ATO?

Honest answer: 6 to 14 months from kickoff for a Moderate-impact system, depending on agency cadence and whether you're inheriting an existing CSP authorization. The build itself is rarely the bottleneck — the slow steps are control implementation evidence, independent assessment by a 3PAO if FedRAMP, and the AO's review queue. Anyone quoting you 90 days end-to-end is selling something.

Do you work as a prime or as a sub under a larger integrator?

Both. We prime SDVOSB set-asides directly when the ceiling and scope fit. On larger vehicles — SeaPort-NxG, OASIS+, CIO-SP3, Alliant 2 — we sub to primes who need SDVOSB participation to hit small business goals. We've found primes value subs who deliver clean CDRLs and don't create contract-modification drama, and we operate that way.

How do you handle Section 508 accessibility?

508 is treated as a functional requirement, not a checkbox. We run axe-core in CI on every PR against WCAG 2.1 AA, do manual screen reader passes (JAWS, NVDA, VoiceOver) on critical workflows each sprint, and produce an ACR using the latest VPAT 2.5 template at delivery. Retrofitting 508 at the end of a project typically costs 15-25% of the original build — designing it in from sprint one is materially cheaper.

What cloud environments do you build in?

AWS GovCloud (US) and Azure Government are the defaults for CUI and FedRAMP Moderate workloads. For systems handling only public or low-impact data, commercial AWS or Azure with FedRAMP Tailored can work and saves significant cost. For DoD IL4/IL5 we use AWS GovCloud or Azure Government with the appropriate boundary. We'll recommend the lowest-friction environment that satisfies your data classification — not the most expensive one.

Can you integrate AI/LLMs into a federal system?

Yes, with caveats most vendors gloss over. Commercial OpenAI and Anthropic APIs aren't FedRAMP authorized as of this writing — for CUI workloads you need Azure OpenAI in Azure Government, AWS Bedrock in GovCloud, or a self-hosted model on accredited infrastructure. We've built RAG pipelines on Bedrock with Titan and Claude in GovCloud, with full prompt/response audit logging to satisfy records management and FOIA requirements.

What happens when the contract ends or transitions to another vendor?

Government work is built on transitions — PMs rotate, contracts recompete, primes change. We design for that day from the start: infrastructure as code (Terraform or CloudFormation), runbooks in the repo, ADRs for every non-obvious decision, and a 30/60/90 transition plan. The deliverable isn't just running software; it's a system the next team can operate without a six-month learning curve.

Do you hold security clearances?

Members of our team hold active Secret and TS/SCI clearances. We can staff cleared engineers onto programs that require them, and we maintain a facility security clearance pathway through sponsorship when a contract requires it. For unclassified-but-sensitive work (CUI, ITAR-adjacent), we use US persons only and document personnel screening to NIST 800-53 PS-controls.
