Who we are

A Virginia software company formed to deliver for the public sector, led by a founder with a B.S. in Computer Science from James Madison University. The practice is defined by the problem, not the platform — and it takes the work end to end.

Core competencies

Twelve competencies, one delivery model. Web and mobile are surfaces the work lands on, not the boundary of the practice.

  1. 01

    Custom software development & systems engineering

    Applications, internal tools, case and workflow systems, and the integrations between them.

  2. 02

    Data integration, pipelines & reporting

    Multi-source ingestion, normalization, scheduled sync, deduplication, entity resolution.

  3. 03

    Legacy modernization & migration

    Off unsupported platforms — records, data and URL structure preserved, not re-keyed.

  4. 04

    Workflow automation & business-rules engines

    Written policy turned into software that applies it the same way every time.

  5. 05

    Web applications & public-facing digital services

    Next.js, React and TypeScript. Fast, typed, standards-based.

  6. 06

    Mobile application development

    Native Swift and SwiftUI, plus Flutter. Full App Store lifecycle.

  7. 07

    Cloud architecture, databases & DevOps

    Schema design, forward-only migrations against live databases, CI/CD, hosting.

  8. 08

    Security, access control & auditability

    Role-based access, enforced separation of duties, append-only hash-chained audit trails.

  9. 09

    Accessibility & Section 508 engineering

    WCAG 2.1 AA, gated automatically. A release fails on any violation.

  10. 10

    UI/UX & design systems

    Interface design, design systems and identity, delivered with the software.

  11. 11

    Rapid prototyping & MVP delivery

    A hosted, clickable artifact before the expensive decisions get made.

  12. 12

    Operations, maintenance & sustainment

    Monitoring, security updates, enhancements. Retainer or task order.

Full capability detail

Why this firm

01 — Engineer-led

A builder, not a reseller.

Technical questions get answered by the person who wrote the code, in the same conversation.

02 — End to end

Full lifecycle, entirely in-house.

Design through deployment through maintenance. No vendor can point at another when something breaks.

03 — Proven throughput

Automation, demonstrated at volume.

260+ web systems from one scripted build, quality-check and publish loop. Speed here is engineering.

04 — Fit to purpose

The stack follows the mission.

No platform to upsell, no partner tier to protect. The architecture is chosen for the requirement.

Selected work

Working systems built as solicitation exhibits. Evidence of a capability, not a product line.
