Chelsea Kelly-Reif

Engineering leader for state and local public technology

Director of Engineering, CiviForm · Exygy

I learned this work inside California government and carried it into statewide workforce services, transit data, housing, energy, utilities, and social services. I lead teams, set architecture, and write code for public systems that make decisions clearer and leave people with more agency.

Notes from the work: engineering leadership, accessibility, public systems, and AI people can inspect.

  • A missing answer is not a no

    In the Medicaid unwinding, most people who lost coverage were never determined ineligible. Their case just did not hear back, and the system recorded that the same way it records a no.

  • There is no value the system treats as true

    The federal government has cut Medicaid funding for transgender children's care, running the exclusion through data systems I spent years helping build. The field that records who we are is one character wide, and it was never fixed.

  • Staying close without becoming the bottleneck

    I moved from principal engineer to managing managers without wanting to leave the architecture behind. The harder lesson was how to stay accountable without making myself the route every important decision had to travel.

    GTFS Scorecard: plain-language quality for transit feeds

    I run GTFS Scorecard, a live service that reads more than 2,100 published GTFS feed records and turns each one into a plain-language scorecard with a first recommended fix. Structural correctness comes from MobilityData's canonical validator; the scorecard adds freshness, rider-information, and realtime checks on top. Feed records are not necessarily distinct agencies, and no agency is known to have adopted a scorecard into its workflow.

    TODS Validate: findings a scheduler can act on

    I build tods-validate, a beta validator for the Transit Operational Data Standard, the open standard for crew runs, deadheads, and vehicle assignments that rides as an overlay on an agency's GTFS feed. It checks a package against TODS v2.1.0 and reports what is wrong, where, and what good looks like, with the spec section cited behind every finding. No agency adoption or production use is claimed.

    Permit Bearings: know the path in

    I designed and deployed a California housing-permitting prototype that screens a bounded statewide ADU, JADU, and SB 9 baseline across 541 recognized jurisdictions and produces a printable handoff for local staff. Woodland remains the deep synthetic packet fixture; no applicant, planner, or jurisdiction has validated it.

    Habitable: keep the repair trail in tenants’ hands

    I designed and built a working local-first alpha that turns conditions, repair requests, responses, and captured media into a source-aware repair trail and deliberate review copy—without a project-operated tenant-case database. It has only synthetic examples and is not ready for real legal matters.

About

Leadership scale without losing the technical thread.

I came up inside California government and later led a 22-person engineering structure through three Directors. My work is state, local, and mission-forward public-interest technology, where organizational leadership and hands-on technical judgment both matter. I do not take on federal contracting work.

Working on state or local public technology?

I am glad to talk about public systems, the standards under them, and the evidence behind the claims made for them. I do not take on federal contracting work.
