About LUCA LLC · Lincoln, Nebraska · Omaha, Nebraska · Denver, Colorado

Two architects. Zero friction.

LUCA LLC is led by two principals across Technology, Media, medical billing, and NEXUS OS. The first three are staffed services with their own buyers and scopes. NEXUS is software, with product-specific customer-use gates. Our operating experience informs both, but buying a service does not silently include a software product.

Lucy Mfinanga

Lucy Mfinanga

Lead Solution Architect · Platform Engineer + Revenue & Admin Operations

Lucy holds an M.S. in Computer Science and engineered enterprise telecom and networking systems before founding LUCA's platform practice. She is the architect of NEXUS OS: she leads engineering decisions, owns the full stack from infrastructure to front-end, and builds custom systems rather than templates. Her work does not stop at code. Lucy runs LUCA's medical-billing operations and leads its revenue-cycle staff training. That medical billing service is staffed labor; NEXUS RCM is separate software for teams that want to operate the tool themselves.

The work

  • 01

    Technology

    Network infrastructure, cybersecurity, workplace systems, and software engineering. Samuel brings 20+ years in managed technology and infrastructure consulting; remote U.S. work and on-site needs are confirmed in the scope.

  • 02

    Media

    Corporate event coverage, executive interviews, brand films, and photography, with multi-camera live streaming from the production van when the event calls for it.

  • 03

    Billing & Medical Equipment

    Home-health billing, eligibility, notices, claim preparation, and denial follow-up. OASIS assessments and clinical documentation stay with the clinician; payer and coding responsibilities are agreed before work begins.

  • 04

    NEXUS OS

    The platform LUCA develops for its own operations and other organizations. Each product has its own availability and customer-use gate.

How we work

  • Systems thinking

    Every engagement starts with the whole system, not only the symptom. The workflow should still be useful after the first fix.

  • Friction comes out

    Manual handoffs, broken integrations, and data that lives in two places cost money every day. We engineer that out.

  • Operator mentality

    We run a company ourselves. We plan for the cost of interruptions, clear ownership, and recovery. Support hours and escalation responsibilities are agreed in your service scope.

  • Practical automation

    Repeatable work gets an auditable system, so the team can stay on decisions, relationships, and outcomes.
