Field Work

Systems I've shipped, end to end.

Side projects, run like production: designed, built, deployed, and operated — data pipelines to payment flows to the Kubernetes clusters underneath. The same rigor I bring to client systems.

01 / LienPulse

Geospatial deal analysis for county lien auctions.

A real-estate intelligence platform that ingests county tax-auction data and turns it into ranked, mappable deals. Properties are scored by estimated-value-to-bid ratio, clustered on an interactive map, and filterable by county, city, price, and auction status.

Design, backend, frontend, data pipeline & infra — solo build

  • Kotlin / Spring Boot
  • PostgreSQL + PostGIS
  • Leaflet
  • Flyway
  • Stripe
  • Docker / Kubernetes
  • Interactive county map with marker clustering and color-coded deal quality
  • Deal scoring engine ranks every property by Est/Bid ratio (Great / Good / Fair / Over)
  • Multi-facet filtering: county, city, price range, auction date, favorites
  • JWT + Google OAuth authentication with per-auction Stripe purchases

02 / Family Reunion Website

A production event platform for a 180-person family reunion.

Full-stack RSVP and reunion planning platform running live in production: multi-person family RSVPs, per-family fee calculation with Stripe checkout, an interactive multi-generation family tree, QR-code check-in with SMS notifications, and a role-gated admin panel.

  • Vite
  • Kotlin / Spring Boot
  • PostgreSQL + Flyway
  • Google OAuth
  • Stripe
  • Twilio SMS
  • K3s on Oracle Cloud
  • Interactive d3 family tree spanning five generations and 180+ members
  • Multi-person RSVP with per-family budget math and Stripe payments

03 / Enoc Construction

A marketing site with a hardened self-serve photo pipeline.

Before/after showcase site for a renovation contractor, built as a single deployable Spring Boot JAR. Visitors compare transformations with draggable sliders; the owner uploads new project photos through a token-guarded admin flow — no developer needed.

Design, backend, frontend & hardening — solo build

  • Kotlin / Spring Boot
  • Vanilla JS
  • H2 file database
  • Single-JAR deploy
  • Draggable before/after comparison sliders on every project card
  • Uploads validated by image magic bytes — client Content-Type is never trusted
  • UUID-renamed storage with path-traversal protection and immutable cache headers
  • 16 integration tests covering the API and upload security paths
