Backend & API Development

Typed services in Node, Go and Elixir — secure, tested, observable.

We build backends that hold up under load. Typed end-to-end, tested in CI, observable in production, designed for the failure modes you have — not the ones a textbook assumes.

What you get

  • ◆REST, GraphQL or gRPC API design and implementation
  • ◆Typed end-to-end (TypeScript, Go, Elixir)
  • ◆Postgres schema design, migrations, query tuning

How we work

  1. 01DiscoveryDomain modeling, SLO definition, integration map, threat model.
  2. 02DesignSchema-first API design, data model, contract tests with the frontend.
  3. 03BuildSprints with CI, automated test coverage, preview environments.
  4. 04LaunchLoad testing, security review, observability stack live, runbooks written.
  5. 05OperateSLO monitoring, incident response, quarterly capacity review.

Outcomes

  • ◆p95 API latency under 200ms at target load
  • ◆99.9%+ uptime SLO
  • ◆80%+ test coverage on business logic
  • ◆Mean time to detect under 5 minutes

Ideal for

  • ◆Frontend-heavy teams that need a senior backend partner
  • ◆Companies replacing a monolith or untangling a microservice tangle
  • ◆Startups that need a typed, test-covered foundation
  • ◆Enterprises modernizing legacy services

Frequently asked

Node, Go or Elixir — how do you choose?

Node for fast TypeScript end-to-end and rich ecosystem. Go for high throughput, low memory, simple deploy. Elixir for soft-realtime systems with massive concurrency (chat, presence, telemetry). We match the runtime to the problem.

GraphQL or REST?

GraphQL when the client mix is varied or evolving fast. REST when the API surface is stable and consumers are simple. Sometimes both, behind a gateway.

Do you write tests?

Always. Unit + integration + contract tests in CI, with coverage targets enforced. Tests are part of the deliverable, not an afterthought.
