Building a smarter tomorrow

We design and build software, mobile apps and websites, and we bring AI, cloud and security expertise to every project.

Capabilities

The stack we work in every day

We build enterprise back ends in Java, modern front ends in React, and run them on managed SQL databases in the cloud. AI tools are part of how we plan, write and review code.

Back end

  • Java 21
  • Spring Boot 3
  • Spring Security
  • REST & GraphQL APIs
  • JUnit & Testcontainers

Front end

  • React
  • TypeScript
  • Next.js
  • Tailwind CSS
  • React Native

Data

  • PostgreSQL
  • AlloyDB
  • Cloud SQL
  • MySQL
  • pgvector

Cloud & DevOps

  • Google Cloud
  • Cloud Run
  • GKE
  • Docker
  • GitHub Actions
  • Terraform

AI-assisted engineering

  • Claude
  • Gemini
  • GitHub Copilot
  • Agentic AI workflows
  • Spec Kit (spec-driven development)
How we work

From idea to launch

Every project follows the same four stages, so you always know what happens next and what you'll get at the end of each one.

Discover

We learn your goals, users and constraints, then agree on scope and a timeline.

Design

Wireframes and visual design you can click through before any code is written.

Build

Short sprints with a working demo every two weeks, so nothing is a surprise.

Launch & support

We ship, monitor and keep improving the product after it goes live.

Demo projects

Open-source demos you can try

Working reference apps that show how we build. Each one has a live demo, the full source code, and the specs we wrote with Spec Kit before writing any code.

Planned

Clinic booking platform

Patients book appointments and clinics manage schedules. A Spring Boot API with role-based security, a React dashboard, and PostgreSQL with Flyway migrations.

  • Java 21
  • Spring Boot
  • React
  • PostgreSQL
  • Cloud Run
  • Cloud SQL
Planned

AI support agent

An agent that answers customer questions from a knowledge base and opens tickets on its own, using tool calling and vector search in the database.

  • Agentic AI
  • Claude / Gemini
  • Spring AI
  • AlloyDB / pgvector
  • React
Planned

Spec-driven inventory API

An inventory and orders service built end to end with Spec Kit and Copilot, from spec to plan to tasks to tested code, with CI deploying to Google Cloud.

  • Spec Kit
  • GitHub Copilot
  • Spring Boot
  • PostgreSQL
  • GitHub Actions
  • Terraform
