Software built
to last.
Celestial Code is an independent software studio. We build web apps, data pipelines, and tools that turn messy public and private data into something people can actually use.

Indiana buried infrastructure map · Live
Every public utility record in Indiana, on one map.
Indiana's buried-utility data is scattered across dozens of city, county, and state GIS portals, each with its own format. We collected it, cleaned it, and put it on a single fast map. You can filter it by county, search an address, or look at the lines underground in 3D.
92counties covered
80+public data layers
55k miof mapped lines
- Water, sewer, storm, gas, and electric lines, plus buried hazards like old wells, underground tanks, and former gas plants
- A cross-check layer that flags gas lines missing from the state's records
- Anonymous analytics, counted by day and county. No IP addresses are stored.
What we do
From first sketch
to production.
We keep the team small and the scope clear. You work with the engineer who writes your code from the first call through launch.
Data pipelines
We pull data from APIs, files, and legacy systems, then clean it, validate it, and load it on a schedule. Every run is logged and tested.
GIS & mapping
Interactive maps that stay fast with millions of features. We handle public GIS harvesting, vector tiles, 3D views, and geocoding.
AI & automation
LLM features and workflow automation with a person approving the steps that matter. We test them on your real data before anything ships.
APIs & integrations
REST APIs, webhooks, and integrations with third-party services. Each one comes with documentation, versioning, and monitoring.
Infrastructure & security
Self-hosted or cloud deployments, CI/CD, backups, and hardening. That includes compliance-aware setups for teams that handle sensitive data.

How we work
Clear steps.
No surprises.
Discovery
A free call to understand the problem, the users, and the constraints. You get a written scope and an estimate.
Design
We plan the architecture, the data model, and the screens, and you approve them before we build anything.
Build
We work in short iterations. You get working preview links along the way, so you always know where things stand.
Launch & support
We test it, deploy it, write handover docs, and stay available after launch.
About
Built on curiosity,
driven by craft.
Celestial Code LLC was founded on a simple belief: great software is part science and part art.
We're a small studio, and that's on purpose. Every project gets senior engineering attention from the first call through launch, and we stay around afterward. We like hard data problems, and we care about building tools that are honest about their limits.
Precision
We sweat the details most people overlook.
Integrity
Honest timelines, honest code, honest partnership.
Ambition
We take on problems others call too messy.
Longevity
We build software meant to last for years.
