Java, Python, integrations, and websites — built right, by someone who’s done it before.
Most consulting shops either (a) work only inside one stack they specialize in, or (b) farm out everything except the architect to junior staff. Stonebridge does neither. We take on the kind of custom-software work where the value comes from a senior engineer reading your existing system, understanding what it actually needs, and writing the smallest piece of code that solves the problem.
What we help with
- Java services and APIs. Spring Boot, Dropwizard, or just plain Java — picked based on what your team will maintain after we’re done. Patterns from production-scale environments brought to your scale.
- Python automation and tooling. Scripts that have to be reliable, scheduled, observable, and not “the one Bob wrote that nobody understands.” We’ve built a lot of pyVmomi automation in particular for VMware-heavy shops.
- Integrations. SaaS-to-SaaS, ERP-to-storefront, accounting-to-billing, the gnarly middle. We don’t sell you a Zapier subscription and a smile; we write the integration the way you’d write it if you had time.
- Prototypes and proofs-of-value. A one-week sprint to take an idea from “we’ve been discussing this for a quarter” to “here’s a working demo and here’s what it would take to productionize.”
- Custom website engineering. Hugo, Astro, Next.js, plain HTML — whatever fits your team’s maintenance budget. Performance-first. Fast deploys. Predictable hosting.
A note on website builds
We do the engineering. We don’t do design.
If you already have a designer (or an existing brand and a wireframe), we’ll build it cleanly, performantly, and in a stack you can maintain after we’re gone. If you don’t, we’ll happily recommend designers we’ve worked with — but we won’t be the ones picking your colors or laying out your hero. Design is a specialty that deserves a specialist, and the worst websites are the ones built by engineers pretending to be designers.
Typical engagements
- One-week prototype. Fixed-fee. Written brief on Monday, deployed and demoable prototype by Friday. Includes a one-page writeup on what hardening for production would take.
- Integration project. Two to four weeks depending on shape. Discovery → written design doc → implementation → runbook. The runbook is the deliverable as much as the code is.
- Custom Java or Python service. Scope-dependent. Usually three to eight weeks from kickoff to deployed-and-monitored.
- Website engineering build. One to four weeks for a marketing site (you bring the design); longer for a custom CMS or interactive app.
Why us
Stonebridge ships its own custom software in production every week: this site, yavijava, the yavijava SSO commercial library, and a quiet portfolio of internal tools across Java, Python, and shell. The work you’d hire us for is the work we already do for ourselves.
