## About

SigmaJunction is an engineering firm: we design, build and operate custom platforms, applied AI and business automation - the systems your business runs on. Senior teams only. Milestone billing, fixed estimates that hold, and equity terms when we believe enough to co-own the outcome.

What we do: custom software development - operational platforms, customer-facing products, internal tools and legacy modernisation; applied AI - document intelligence, copilots, agentic workflows and forecasting models; and business automation across the tools you already use, with monitoring, retries and human checkpoints on exceptions.

How we work: four phases, each with an exit door. A free diagnosis of your operations, numbers and constraints. A free estimate with architecture, milestones, timeline, cost and the business metric the system answers to. A build with working software from week two, weekly demos and milestones you accept before paying. Then we operate the system on a retainer or hand it over cleanly.

Three ways to engage: a dedicated senior squad at a fixed monthly rate, per-project with fixed estimates and milestone billing, or a partnership where part or all of the build value converts to equity. The estimate holds - overruns are ours. Everything ships with a 90-day warranty, documentation, tests and CI/CD, and the first invoice comes after the first delivery.

Stack: TypeScript and Node, Go, .NET and C#, Python, Rust, React and Next.js, React Native, AWS, Google Cloud and Azure, Kubernetes and serverless, Terraform, SQL, NoSQL and event streams.

Industries: logistics and freight, iGaming and betting, financial services, legal, healthcare, retail and e-commerce, manufacturing, and SaaS product companies.
