Enterprise software · Federal programs
Proven components for programs that cannot go down.
Lemma Systems builds and sustains the software layer federal agencies and their primes depend on — custom applications, data integration, and cloud infrastructure.
Small senior teams. Working software every two weeks. Runbooks and handover shipped with the code, so the government is never locked in by undocumented knowledge.
Capabilities
Six things we do, and do properly.
We are a software firm, not a staffing firm. Every engagement below is delivered by the people who scoped it.
Application development
Custom software in .NET, Java, and Python — and the decomposition of legacy monoliths into services without taking the system offline.
Cloud & infrastructure
AWS and Azure migration, infrastructure as code, and environment builds that are repeatable inside an accredited boundary.
Data engineering
Batch and streaming pipelines, and API-first integration across systems of record that were never designed to talk to each other.
DevSecOps
Pipelines with automated STIG and dependency scanning, signed artifacts, and compliance evidence generated as a build output.
Application security
SAST and DAST in the pipeline, dependency and supply-chain review, and remediation carried through to closure rather than to a ticket.
Operations & sustainment
SLA-backed maintenance, incident response, and the unglamorous work of keeping a delivered system healthy for years.
Why Lemma
The difference is who writes the code.
Senior teams, no pyramid
The engineers who scope the work build it. We do not win a contract with principals and staff it with juniors.
Working software every two weeks
Progress is shown in a running system, not a status deck — which makes scope problems visible while they are still cheap to fix.
Handover is a deliverable
Architecture decision records, runbooks, and environment builds ship with the code. You can replace us without a rebuild.
For contracting officers
Registered, and straightforward to buy from.
Our registration details, NAICS and PSC codes, socio-economic status, and teaming posture are on one page — along with a one-page capability statement you can drop straight into a file.
Have a program that needs building or rescuing?
Tell us the system, the constraint, and the deadline. We will tell you honestly whether we are the right firm for it.
