Washington, D.C., DC · Custom Software + AI

Custom software for Washington, D.C. — built the AI-native way.

We pair senior engineers with an AI-accelerated delivery model to ship custom software for D.C., Northern Virginia, and Maryland operators — government, defense, and the contractors that serve them — without the fragile output that gives AI a bad name.

Senior-only engineering · AI-accelerated delivery · you own 100% of the code

AI changed the economics of custom software. We rebuilt our process around it.

The DMV anchors the country's largest government, defense, and cybersecurity software market, with a deep contracting, FedRAMP, and intelligence-community engineering ecosystem from Arlington to Tysons to Fort Meade. Senior hires are cleared, six figures, months out, and picked over by primes, mid-tier integrators, and the agencies themselves. AI changes the math, but only when senior people own the parts AI gets wrong.

On a DMV gov or defense build, AI is fast and useful for the repetitive 70% — schemas, CRUD, dashboards, scaffolding, glue. The 30% AI gets confidently wrong is the part FedRAMP, CMMC, or your 3PAO will actually score: boundary diagrams that don't match the code, logging that doesn't cover an authentication event, supply-chain provenance that AI invents, accessibility (508) edge cases, and integration with cleared systems that AI can't see. Raw AI output fails those controls invisibly.

We build for DMV operators — civilian agencies modernizing public-facing services, defense and intel software vendors shipping into contract milestones, GovTech startups working toward FedRAMP, and the contractors that need senior engineering capacity without adding cleared headcount. Our model: AI handles scaffolding and the repetitive 70%; a senior engineer owns architecture, security review, and signs off on every change.

Show, don't tell

AI writes the first draft. A senior engineer signs off.

Every change runs through review for security, tests, and architecture before it ships — that review is the product.

On a DMV gov or defense build, the failure modes are logging gaps against AU/IA controls, boundary diagrams that don't match code, and 508 misses. Senior review catches them before a 3PAO or an agency assessor does.

What we build for Washington, D.C. companies.

Public Sector

GovTech & FedRAMP-ready apps

Citizen-facing services and internal systems built for procurement, accessibility, and audit.

Defense

Defense & national-security software

Mission tools and analytics built for the security, classification, and integration standards your contracts require.

AI

AI applications

Copilots, RAG, search, and agents grounded in your data, with guardrails and evals.

Modernize

Modernization

Move legacy systems onto a modern, maintainable stack — incrementally, no big-bang.

Product

SaaS platforms

Multi-tenant products with auth, billing, and dashboards — MVP to scale.

Internal

Internal tools & copilots

Operations tooling that replaces the spreadsheet-and-tribal-knowledge workflow.

Senior, on-shore, AI-accelerated

A senior team that moves at AI speed.

You work with senior engineers in Eastern Time who own architecture, control-mapping, and quality on the unclassified surface of your work — fitting alongside an Arlington prime, a Tysons subcontractor, or a Bethesda civilian team — not a junior pool dropping raw AI output into a control catalog.

The DMV senior engineering market is dominated by clearance status and prime-contractor headcount — three-to-six months to hire uncleared, much longer cleared. An AI-native team accelerates the unclassified portion of your scope this week and frees your cleared bench for the work only they can do.

Common questions from Washington, D.C. teams.

Do you work with Washington, D.C. companies?
Yes — we serve Washington, D.C., Baltimore, and Richmond companies with senior, on-shore engineers in Eastern Time. Most collaboration is remote-first, with on-site available for kickoffs and key milestones.
Do you work with FedRAMP, CMMC, or NIST 800-53 environments?
Yes. We architect with the control catalog in mind from day one — boundary design, logging, identity, supply-chain hygiene — and we've shipped into FedRAMP-adjacent environments. We don't deliver an ATO; we build code that survives the audit your 3PAO does.
Can you ship into a FedRAMP-moderate or DoD IL4 environment?
Yes — we build with the control catalog in mind from day one, can target GovCloud, and structure the unclassified portion of work for clean integration with your cleared bench. We don't deliver an ATO; we deliver code your 3PAO can audit without rewriting.
Is AI-built software production-ready?
Yes — when a senior engineer reviews every output, adds tests, and hardens it. The horror stories come from shipping raw AI code unsupervised. We don't, and we support what we ship.
Will we own the code?
100%, from day one. We deliver to a repository you control — no proprietary platform, no lock-in.
How fast can we start?
Usually within days. A short scoping call defines the build, the timeline, and a fixed quote.
Can you work with our existing team?
Yes — we augment in-house teams, review their work, and set standards, or run the build end to end. We flex to how you work.
