Custom API Development Services for Web, Mobile, and SaaS Applications

We build the systems your users never see databases, business logic, authentication, integrations, and the APIs that connect everything. Whether you’re launching a new product, replacing a legacy backend, or exposing an existing system through clean API development services, we focus on how the system behaves under real traffic, real data, and real failure conditions, not how it looks in a demo.

    API & Backend Development Professional
    What You Actually Get

    Backend Work That Supports Real Product Decisions

    Most backend problems come from early decisions a database schema that stopped fitting the product, an API contract nobody agreed on, or business logic scattered across three services. Our api and backend development services address the parts of the system that shape how everything else behaves later.

    Where Our API Development Services and Backend Work Meet Your Product

    Custom Backend
    Development

    Server-side applications covering business logic, data models, background jobs, and the internal services behind your product.

    REST API
    Development

    Resource-based APIs with clear endpoints, predictable responses, authentication, versioning, and documentation your integration partners can work with.

    GraphQL API
    Development

    Schema design, resolver architecture, and caching decisions that make GraphQL practical when clients need flexible, varied data shapes.

    Third-Party API
    Integration

    Payment, CRM, ERP, shipping, and messaging integrations with proper retries, webhooks, idempotency, and failure handling built in.

    Backend Architecture & Engineering

    Payment, CRM, ERP, shipping, and messaging integrations with proper retries, webhooks, idempotency, and failure handling built in.

    Database Design &
    Data Layer

    Schema design, indexing, query optimization, and migrations across PostgreSQL, MySQL, MongoDB, DynamoDB, and Redis based on your data model.

    How We Think About
    Backend Projects

    A simple mobile app with basic logins has little in common with a multi-tenant SaaS platform that handles permissions, subscriptions, and reporting. That’s why our custom SaaS app development starts with understanding what your system needs to do, then deciding what to build.

    Requirements & System Analysis

    Understanding what the application does, who uses it, what data flows through it, and which external systems it needs to talk to first, before any code is written.

    Architecture
    Selection

    Monolith, modular monolith, or microservices, each with real trade-offs, chosen based on the product's actual needs rather than what's currently fashionable.

    API & Data
    Modeling

    Defining resources, queries, relationships, and service boundaries upfront, because API contracts and database schemas are hard to change once clients depend on them.

    Authentication & Authorization Design

    Handling identity and permissions as separate problems, and deciding when an existing provider (Auth0, Cognito, Firebase Auth, Clerk) fits better than custom logic.

    Integration & Failure Planning

    Planning for retries, webhook duplicates, rate limits, and third-party outages with idempotency keys, dead-letter queues, and clear logging from day one.

    A Backend Team That Works Across Languages, Frameworks, and Clouds

    Bring Us Your Backend Problem, We’ll Walk Through It With You

    Bring what you have: an idea, a spec, an existing codebase, or a rough sketch. Our API and backend development services start with a conversation about what the system needs to do, what already exists, and what actually needs to be built. From there, we’ll put together a realistic scope, timeline, and approach.

    Frequently Asked Questions (FAQs)

    Q1. What's the difference between API and backend development?

    The backend is the server-side application business logic, database, authentication, and integrations. An API is the interface through which other applications talk to that backend. Most projects need both a backend that does the work, and APIs through which clients access it.

    Q2. When does a business actually need custom backend development?

    When off-the-shelf tools don't cover the requirements. If a standard CMS, e-commerce platform, or Backend-as-a-Service product handles what you need, custom work is unnecessary. Custom backend development services make sense when the application needs specialized business logic, complex permissions, unusual integrations, or APIs no packaged product provides.

    Q3. REST or GraphQL: which one should we use?

    Neither is universally better. REST is simpler, well-understood, and cache-friendly. GraphQL fits when clients need flexible queries over related data or when multiple frontends share the same backend. The right choice depends on your frontend, data model, and team familiarity, not on trend.

    Q4. How much does API and backend development cost?

    It depends on scope. Cost is driven by API surface area, business logic complexity, database design, number of integrations, authentication requirements, and infrastructure setup. A realistic range comes after a scoping conversation, any number before that is a guess.

    Q5. Can the backend integrate with our existing CRM, ERP, payments, or third-party systems?

    Yes, integrations are a core part of most backend projects. The approach depends on what those systems expose: REST, GraphQL, SOAP, webhooks, or file-based exchanges. Authentication, data mapping, retries, and failure handling are built in from the start.
