Backend & API Development

Good products need a sound foundation.

APIs, data models, and business logic that give web and mobile experiences a dependable center.

The problem worth solving

Complexity collects between systems

Duplicate requests, inconsistent records, unclear ownership, and fragile integrations can turn small changes into difficult releases. The backend needs clear boundaries before it needs more services.

A good fit: For new applications, growing products, and teams needing an API or data layer that is easier to understand and change.

Scope / deliverables

What we can build together.

01

Architecture and data

Define domain boundaries, record lifecycles, access rules, and transaction requirements before choosing the shape of the system.

02

API design

Explicit contracts, validation, pagination, error responses, and versioning help clients integrate without guessing.

03

Reliability and security practices

Plan authorization, idempotency, safe retries, observability, and failure recovery around the consequences of each operation.

An engineering consideration

Start with boundaries, not service count

A modular monolith can make ownership and consistency easier to reason about. Distributed services bring additional operational costs and should solve a concrete problem.

The engagement

Make each step reviewable.

Scope, dependencies, and acceptance criteria are agreed before a delivery commitment. Reviews keep the work connected to the original problem.

  1. 01

    Review data and domain boundaries

  2. 02

    Implement and document contracts

  3. 03

    Exercise failure, retry, and authorization paths

Connected evidence

Architecture with an accounting constraint

Dairify’s design specifies a NestJS modular monolith, PostgreSQL, shared validation, and exact-integer money handling. These are design decisions for an early-stage product.

Questions / answers

A little more clarity.

Can you integrate third-party APIs?

Yes. We examine authentication, quotas, data ownership, change notifications, and failure behavior before committing to the integration.

Do we need microservices?

Only when their benefits justify the operational complexity. A well-structured single application is often a useful starting point.

Will the API be documented?

Documentation and representative examples should be included in the delivery scope so another team can use and maintain the interface.

Connected capabilities

The next piece of the system.

Good work starts with a conversation
