Consulting and technical architecture
Software delivered end to end, by one accountable team.
Zavon designs, builds and operates software for clients: product builds, embedded engineering, technical leadership and the architecture that holds it together.
Engagements
Three ways to work with Zavon
Every engagement has one accountable owner. There are no hand-offs to a separate bench: the engineers who scope the work deliver it.
Architecture
Technical architecture
Zavon designs systems its own team would be willing to operate. The same practice runs Zavon's products in production every day: a multi-tenant platform serving several organisations from one deployment, single sign-on across six products, payments, messaging and workflows meeting at well-defined contracts.
Architecture reviews
An independent read of an existing system: risks, costs and the order to address them in, written down.
Platform and multi-tenant design
Tenancy, data boundaries, configuration and the operational model for software that serves many customers from one deployment.
Identity and access
OAuth2 and OpenID Connect, single sign-on, passkeys, roles and permissions that can be audited.
Integration and APIs
REST and GraphQL APIs, webhooks, payment gateways and data pipelines between systems that were never designed to meet.
Cloud infrastructure
AWS, Vercel and Cloudflare, containers, CI/CD and observability, sized for the load the system really has.
AI in real workflows
Assistants, automations and retrieval pipelines scoped to small, measurable wins, with care for the client's data.

Process
How an engagement runs
Weeks 1–2
Chart
A focused discovery of business goals, users and constraints, closed by a written architecture brief the client keeps whether or not the work continues.
Weeks 2–8
Set sail
A small, focused team, weekly demonstrations and working software in a production environment from the second week.
Weeks 6–12
Steer
Integrations, polish, observability and the hardening that turns a working demonstration into a system that runs for years.
Week 10 onwards
Harbour
Launch, hand-over and ongoing operation, or a clean exit with documentation the client's own team can take forward.
