Backend systems SaaS can’t give you.

APIs, services, databases, integrations, and infra. Shipped as documented, observable, versioned software you own. One senior team, start to finish. Clean handoff whenever you want it.

One team · one codebase · one handoff

01

Services with real boundaries. Contracts that hold under load.

02

APIs, databases, and integrations designed together, not bolted on.

03

Architecture shaped around scale, security, and the people running it.

What one backend team covers.

Service architecture, business logic, APIs, databases, infra, and release quality — handled in one engagement.

01

Service architecture

Boundaries, ownership, and contracts drawn on purpose — so services stop leaking into each other as the product grows.

Databases and persistence

Relational and document models, migrations, query strategy, integrity controls. The schema is a feature, not a side effect.

Four phases. No surprises.

Same structure every time. The depth scales with the system.

Week 1

Discovery

Product goals, existing systems, integration needs, operational risks. Written down before architecture.

Week 2

Plan

Service boundaries, data model, API contracts, infra posture, release controls. Decided on paper before a line of production code.

Weeks 3–7

Build

Services, APIs, integrations, and deploy pipeline built as one coordinated system. Tests, observability, and staging come with it.

Ship

Ship

Release, monitoring, docs, handoff. Ready for production and for the next iteration — without calling us every month.

Need one senior team across the whole backend?

Services, APIs, data, and infra as one coordinated system. Fewer vendors. Cleaner handoffs. Software that fits together.
