Building Scalable and Secure Server-Side Solutions

BE Engineers

Hire a backend developer from WWG who joins your team and builds the server side of your applications: APIs, databases and architectures that hold under load. This is for CTOs and product leads who have a team and need to cover a back-end skill without opening a recruitment round. The engineer works in your process with Node.js, Nest.js, Express and SQL or NoSQL databases; WWG answers for quality and continuity through a designated owner.

Definition

What does it mean to hire a backend developer

To hire a backend developer through a team-extension service means adding an engineer who works continuously for one client, inside its team and process, on the server side of its applications: APIs, databases, application logic, integrations and security. The engineer remains employed by the provider, which answers for the quality of the work and for continuity, while priorities and reviews come from the client’s technical lead.

The engagement

A dedicated backend developer in concrete terms

Duration
Set in scoping, according to the perimeter: a bounded project or an ongoing collaboration reviewed at agreed checkpoints.
Start
After discovery and planning: business needs, technical requirements and a roadmap, then the profile proposal.
Who does the work
A WWG back-end engineer experienced with Node.js, Nest.js, Express and SQL or NoSQL databases, inside your team. A designated WWG owner answers for quality and continuity.
What we need from you
A technical lead as point of reference, access to repositories and environments, the system requirements and, if it exists, the current code.
Output
A back-end architecture designed for scalability, performance and security; APIs and application logic built and tested; deployment with monitoring and updates.
Format
Monthly fee per engineer inside your process, or a project with a defined perimeter. Documented context for every handover.

The price is set in scoping as a monthly fee per engineer, based on seniority, stack and the commitment required. For a project with a defined perimeter the estimate comes before we start; we do not publish a price list.

Comparison

A dedicated backend developer and the alternatives

Searching for a backend developer mostly returns job boards and freelance platforms. They are legitimate options, but they answer different needs from a dedicated engineer joining your team. This table lines up the four routes.

FAQ

Frequently Asked Questions

A back-end engineer works on the server side of applications: building the application infrastructure, designing and managing databases, exposing the APIs that front-end interfaces and third-party systems use, and making sure communication between interface and logic is reliable and secure. In a product team, this is the person who decides how data is stored, protected and served under load.
WWG’s backend engineering service covers data model and storage design, API and application logic development, integration with third-party services, authentication and data protection, performance tuning and monitoring after release. The work follows four steps: discovery and planning, system design, development and testing, deployment and maintenance. The engineer joins your team and process; a designated WWG owner follows the work.
Node.js is the most frequent choice in WWG back-end teams because it performs well under concurrent load, scales cleanly and has a mature library ecosystem. With Nest.js and Express it allows structured server-side applications that are fast to evolve, in the same language used on the front end. When your system runs on another stack, we assess it in scoping instead of forcing a technology.
Yes. WWG back-end engineers have designed and run systems built for high user volumes and complex workflows, with scalable architectures that absorb growing demand without losing reliability. Scalability is decided in the system design phase, not bolted on afterwards: data model, APIs and infrastructure are drawn for the expected load and for the one after it.
Hiring a backend developer through WWG and picking a freelancer from a marketplace are two different things. The freelancer is one person: continuity, quality and availability depend on them. The WWG engineer works in your team but has an organisation behind them: a designated owner answers for the quality of the work, the context is documented and, if the person changes, the handover is planned. The job boards and freelance platforms that dominate the search results sell the first model; this page describes the second.
The cost of a WWG backend developer is set in scoping as a monthly fee per engineer, based on seniority, stack and the commitment required, not as an hourly rate billed after the fact. The fee is fixed with no hidden costs, so the budget is predictable and there are no recruitment overheads to manage. We do not publish a price list: the same profile on two different systems can call for very different commitments.
Backend developers are not being replaced; what changes is the work. WWG engineers use generative tools for volume work such as boilerplate, test scaffolding and migrations, under their own control and review. The decisions that carry the risk, data model, API contracts, security boundaries, scaling strategy, still belong to a senior engineer who answers for them. A dedicated backend developer is hired for those decisions, not for typing speed.
The duration of a dedicated backend developer engagement is set in scoping, according to the perimeter: a bounded project or an ongoing collaboration reviewed at agreed checkpoints. It starts with discovery and planning, where we understand your business needs and technical requirements, from data storage to API endpoints, and draw a roadmap. We then propose the profile and the engineer joins your process.
To bring in a dedicated backend developer you need a technical lead who sets priorities and reviews code, access to repositories, environments and tools, and the system requirements: planned integrations, security constraints, expected volumes. If the system already exists, we also need the current code and whatever documentation is available. Your team keeps working as before.
Yes. After deployment, WWG engineers provide ongoing support, performance monitoring and updates, so the back-end system keeps meeting business needs as they change. Support can stay inside the same engagement or move to a dedicated maintenance contract: you decide at the end of the development phase, with documented context in either case.
A dedicated backend developer is for companies with a product team and a technical lead that need to cover the server-side skill: building APIs, managing databases, integrating services or making a growing system scale. It is not designed for companies looking for an employee to hire, or for a person with no internal technical guidance: in those cases the right routes are direct recruitment or custom software development.

Who back-end engineers work alongside

A back-end exists to serve something, so these engineers usually sit next to front-end engineers on the same product. Where the gap is inside an existing team, development team augmentation is the route; where the product has to be built from nothing, it starts with custom software development.
