Founding-client prices are 20% off for our first 5 clients. Bigger builds get a fixed quote after the call. Retainers and audits are paid in advance through a Stripe or Relay payment link. If plans change, what you paid carries over to the next piece of work instead of being lost.

Yes, we use AI coding agents

AI-assisted code can help speed up development for our clients. With 10 years of software and systems development experience, we know where AI-assisted code can help and where our expertise shines through. We have experience working in multi-developer environments and know how to review code quality and ensure everything we deliver is well-tested and up to best software engineering practices. You get the speed without the “vibe-code” risk. How an engagement works.

Case studies

A snapshot of some of our past work with clients

All case studies
An illustration with public data, not Sea Island's data or systems: a USGS 3DEP elevation model of Buffalo Bayou in Houston, opened as a plain GeoTIFF and as a COG over the same 50 Mbps connection. The timings are measured reads, replayed in real time. Elevation: USGS 3DEP.

Sea Island Software

Sea Island Software

Seven years of production imagery moved to Cloud Optimized GeoTIFFs on S3, sturdier AWS infrastructure, and legacy Python modernized.

  • Converted seven years of production GeoTIFFs, served as GeoServer imagery mosaics, into Cloud Optimized GeoTIFFs stored in S3
  • Increased resilience with improved AWS CloudFormation templates and auto-scaling rules
  • Refactored older Python processes onto newer GDAL and cloud-native data formats

What we're building

Currently building the GEOSLN Hazard API

GEOSLN is working on its own application, the GEOSLN Hazard API, so you can get a taste of a real working system we’ve built. Aside from consulting, we are building the GEOSLN Hazard API to solve some pain points we have noticed over the years. Right now, the stack runs flood risk lookups by address or coordinate (JRC global flood hazard classes for ten, one-hundred, and five-hundred-year floods), bulk jobs, GIS file conversion and map tiles. Services are available by purchasing credits through Stripe. Environmental screening reports are next.

From the founder

I deeply immersed myself in communities of researchers and scientists early in my career, and I noticed that specialized software was a huge limiting factor across the board. I began learning software engineering because I saw that almost every project could improve immensely with a little automation. While I had the opportunity, I helped automate or speed up small things for the archaeologists and scientists I supported.

Little by little I noticed that I was less an archaeologist or a scientist, and that I could help large organizations tackle bigger problems. Throughout the next phase of my career I continued learning every day about systems, volume, and scale.

I am passionate about taking what I learned and bringing it back to smaller businesses and individuals. As a small business owner myself, I want to enable other small business owners to gain back time, reduce software costs, and build automations that make their businesses run better.
