Baltimore, MD · Custom Software + AI

Custom software for Baltimore — built the AI-native way.

We pair senior engineers with an AI-accelerated delivery model to ship custom software for Baltimore's healthcare, biotech, and federal-civilian operators — 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.

Baltimore anchors one of the country's deepest healthcare and biotech markets — home to Johns Hopkins, the University of Maryland Medical System, NIH-adjacent contractors, the Port of Baltimore, and a fast-growing govtech and B2B SaaS scene. Senior hires are six figures, months out, and picked over by hospital systems, biotech employers, and the venture-backed challengers around them. AI changes the math, but only when senior people own the parts AI gets wrong.

On a Baltimore healthcare, biotech, or federal-civilian build, AI handles the repetitive 70% — schemas, scaffolding, CRUD, dashboards, glue. The 30% AI gets wrong is the part Hopkins engineers, IRBs, your 3PAO, or compliance team will catch: PHI access without audit logging, accessibility regressions on a citizen-facing portal, integration with bespoke research-lab or federal-civilian systems AI invents instead of reads, and supply-chain provenance AI invents instead of documents. Raw AI output ships those silently.

We build for Baltimore operators — Hopkins-adjacent provider-side platforms, biotech and research-tech teams bridging research and production, federal-civilian contractors shipping into FedRAMP-bound programs, port-logistics platforms, B2B SaaS shipping into mid-market buyers, and modernization of decades-old enterprise stacks. 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 Baltimore healthcare, biotech, or govtech build, the failure modes are missing PHI audit trails, boundary leaks against control catalogs, and accessibility regressions. Senior review catches them before a HIPAA review, a 3PAO, or a 508 audit does.

What we build for Baltimore companies.

Healthcare

Healthcare & HIPAA-ready apps

Patient-facing portals, clinician tools, and care-coordination platforms built to HIPAA from day one.

Bio / Life Sci

Biotech & lab software

LIMS extensions, trial-management tools, and AI for research pipelines, validated for regulated environments.

Public Sector

GovTech & FedRAMP-ready apps

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

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.

AI

AI applications

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

Senior, on-shore, AI-accelerated

A senior team that moves at AI speed.

You work with senior engineers in Eastern Time who own architecture, regulated-environment quality, and accessibility — fitting into a Hopkins-area health-IT cadence, an Inner Harbor SaaS standup, or a Federal Hill govtech PR review — not a junior pool with raw AI output bolted on.

Baltimore's senior engineering pool is concentrated around Hopkins, UMMS, federal-civilian contractors, and a growing venture-backed bench — three-to-six months to hire and quietly poached by DMV and remote coastal roles. An AI-native team gets you shipping this week, flexes monthly, and doesn't need an Inner Harbor office.

Common questions from Baltimore teams.

Do you work with Baltimore companies?
Yes — we serve Baltimore, Washington, D.C., and Philadelphia 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 build for HIPAA, IRB, and research-hospital environments?
Yes. We architect for HIPAA from day one — encryption, access logging, audit trails, BAA-friendly data handling — and we respect IRB-approved data-access policies. We don't deliver IRB approval; we build code your compliance team and IRB can sign off on without rework.
Do you work with FedRAMP and federal-civilian 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 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.
