Selected work
Thirteen systems across geospatial, simulation, content management, assessment, booking, payments, monitoring and e-commerce. Every claim here can be opened and checked.
01 — Capability demonstrations
Highgrove builds a complete, working system as part of responding to a solicitation — not a slide deck. Each is Highgrove-owned and can be opened and operated.
Notional exhibits, not delivered contracts, and not built from any buyer's data. Buyers are unnamed while procurements are open; live access on request.
Geospatial · federal data · bilingual
Bilingual mapping application reading four live federal data services in the region's own projection of record, with swipe comparison and state-restoring permalinks.
DemonstratesFederal data integration · geospatial systems · Section 508 gating
Geospatial · data normalization
Seven inconsistent trail systems standardized into one authoritative layer, with every displayed figure reproduced deterministically from full-precision source geometry.
DemonstratesData standardization · reconciliation across inconsistent sources · verifiable derived figures
Simulation · Python API · analytics
Discrete-event Monte Carlo engine behind a live stateless API. Evaluators run real custom simulations, each reproducible exactly from a deterministic run identifier.
DemonstratesSimulation and modeling · statistical analysis · API design · reproducible computation
Enterprise CMS · authoring tooling
Three agency websites unified under one authoring system — 21 routes, two deliberately distinct design languages, nine authoring screens.
DemonstratesEnterprise CMS architecture · multi-tenant content modeling · authoring UX
E-commerce · catalog · reporting
A 111-title catalog with faceted browse, cart and a provably inert checkout, generated from a checksummed source snapshot with machine-readable receipts for every figure.
DemonstratesE-commerce systems · catalog data modeling · deterministic ETL · payment flow architecture
Monitoring · payment architecture
Live uptime, response, accessibility and Core Web Vitals monitoring, plus an eight-screen payment architecture that touches no card data and runs zero JavaScript.
DemonstratesMonitoring and reporting · payment architecture · data publication controls
Reservation systems · structured intake
A four-step booking flow assembling a structured lead entirely in memory, transmitting nothing. With JavaScript off it degrades to one complete, labeled form.
DemonstratesReservation systems · structured data capture · progressive enhancement · schema markup
Learning management · assessment
Course application shell with a working graded assessment engine — baseline locking, differential scoring, item-set hashing — and seeded cohort reporting with drill-down.
DemonstratesLearning management systems · assessment logic · cohort analytics
Public services · multi-audience
Three audiences under one design system. A flight table with live result count, parking status by number, shape and word, and a terminal map whose numbered directory is the map.
DemonstratesPublic-facing digital services · multi-audience information architecture · accessible interactive graphics
02 — Production delivery
Delivered by the principal through Celestial Software — a separate company under common ownership, available for teaming.
E-commerce · brand · marketplace ops · since Jan 2025
Two production e-commerce sites, a full brand and packaging identity, and ongoing marketplace storefront operations automated against the platform's Selling Partner API.
DemonstratesE-commerce systems · third-party API integration · automated operations · brand delivery
Multi-tenant SaaS platform · audit engine
Audits vendor invoices against rate sheets, field tickets and billing history, then says what to pay and what to hold. Rules stored as typed data, so a customer edit needs no deploy and can execute nothing.
DemonstratesBusiness-rules engines · relational data modeling · access control · audit trails
iOS & cross-platform · 2022–2026
Five published under the firm's developer account, three architected end to end by the principal — including a weekly ETL normalizing 78 institutional calendar integrations across two unrelated API standards.
DemonstratesNative mobile architecture · real-time cloud back ends · scheduled data pipelines
Automation at volume · 2025 – present
260+ complete multi-page web systems — 1,047 pages, 255,000+ lines of code — from one scripted seed, build, quality-check and publish loop.
DemonstratesDelivery automation at volume · automated quality gates · repeatable process
