Backend Development at AccsHub Technologies

The back end is everything users never see but always rely on: the server code that processes requests, the database that stores information, the APIs that let apps talk to each other, and the security that keeps data safe.

We design and build back ends for web apps, mobile apps and internal tools, and we extend existing systems that need new features, better performance or cleaner integrations. We write documented, testable code and deploy it to infrastructure you control.

Who it's for

Backend development suits startups building an MVP, mobile app teams that need an API, businesses connecting several tools, companies whose current system is slow or fragile, and agencies that need server-side expertise for client projects.

What's included

The work below can be ordered as a complete backend development project or as individual tasks. Your quote lists exactly which items are in scope.

  • Architecture planning

    Data models, service boundaries and technology choices agreed before code is written.

  • API development

    REST or GraphQL APIs with clear documentation, versioning and error handling.

  • Database design

    Relational or document databases structured for your data, with indexes, migrations and backups.

  • Authentication and roles

    Secure sign-in, password handling, user roles and permission rules.

  • Third-party integrations

    Payment gateways, email and SMS services, CRMs, shipping, maps and other external APIs.

  • Background jobs

    Queues and scheduled tasks for emails, reports, imports and other work that should not slow users down.

  • Performance tuning

    Profiling slow endpoints and queries, caching and efficient data access.

  • Testing

    Automated tests for core logic and endpoints, so changes can be made safely.

  • Deployment and monitoring

    Cloud or VPS deployment, environment configuration, logging and error alerts.

How we deliver

A clear sequence from your first message to the finished work, with your review at every milestone.

  1. Step 1: Requirements

    We map the data, users, integrations and expected load.

  2. Step 2: Design

    We agree the architecture, data model and API contract.

  3. Step 3: Build

    We develop in milestones and share working endpoints early.

  4. Step 4: Test and secure

    We test functionality, permissions and edge cases.

  5. Step 5: Deploy and document

    We deploy, set up monitoring and hand over documentation.

Ask a question
Which languages and frameworks do you use?

We choose well-supported technologies that suit the project and your team, commonly Node.js, Python, PHP and Laravel, with PostgreSQL or MySQL databases. If you have an existing stack, we work within it.

Can you work on our existing back end?

Yes. We start with a code and infrastructure review, then fix, extend or refactor in small, safe steps.

How do you handle security?

We follow established practices such as hashed passwords, parameterised queries, input validation, least-privilege access and secrets kept out of code, and we review permissions as part of testing.

Will we get documentation?

Yes. You receive API documentation, setup instructions and notes on the architecture, so any competent developer can maintain the system.

Who owns the code?

You do. Code is delivered to a repository under your control once the order is completed and paid for.
