Our Cooperation Models for Frontend Development Services

Developing a mobile or web application can be a tedious and long-lasting process. Four Ages makes things easy through the variety of cooperation models. You can benefit from the best front-end developers, even when you already have an in-house IT team.

With our company, it’s possible to create a software product from scratch. We pick up professionals who have extensive experience in front-end technologies. If needed, software architects, business analysts, QA testers, and other IT experts can be assigned to work on your project. Otherwise, our engineers can join your development team as consultants to provide fractional CTO services.

Let’s explore the cooperation model in detail.

Product Development

In this case, you can hire front-end developer professionals to work on your application from the requirements gathering phase to the deployment and maintenance stages. This cooperation model might be beneficial when you don’t have a CTO, for instance, but clearly understand how software is supposed to work to achieve your business objectives.

Team extension

To find a skilled front-end developer for hire, take advantage of our team extension service, also known as staff augmentation. This cooperation model will be fruitful if you already have some experts but want to scale it up by adding front-end engineers with exceptional skills to your team. Four Ages engineers will be working remotely from their locations alongside your IT team. Our remote engineers can also go on business trips to work closely with your in-house team. Under this cooperation model, your company is welcome to coordinate both in-house engineers and our professionals.

How Our Frontend Developers Ensure Code Quality

To deliver software products of the highest quality, our engineers rely on certain approaches to create perfect code. These are also essential to ensure the overall quality of the application.

Best practices

Our developers know the standards and nuances of coding in HTML5, CSS3, and Javascript. They adhere to the best practices for creating solutions with these technologies.

Our front-end engineers also follow the generally established coding conventions. They split code blocks into short units, giving each variable a self-descriptive name and creating built-in comments. What’s more, they document the code itself and its dependencies.

Code review

To hire front-end engineer with Four Ages means that you get an exceptional quality of code as a result of various review procedures.

Our engineers perform a walkthrough of their code. They also apply developer-created tests before this code actually goes to QA engineers. Such an approach grants a 360-degree review of the program code, helping to ensure its quality and portability.

Unit testing

This is an essential procedure for ensuring the executable power and correctness of the application code. Unit testing is necessary to verify the code behavior is correct in response to standard, boundary, and incorrect values.

Our specialists prepare unit tests that correspond to the software requirements specifications. They re-run such tests every time a significant change is applied to the source application code.

Code quality metrics

When you hire a front-end developer with Four Ages, it means that a personal mentor is assigned to these experts. Mentors assess the work done by their mentees and check it for quality, considering cyclomatic complexity (CC), class coupling, and other relevant metrics.

Our mentorship program also implies that each expert on a team has a personal development plan. That way, Four Ages promotes an atmosphere of continuous learning and professional development.

What Clients Say about Our Front-end Development Company

Four Ages has experience in working with companies in 20+ industries. All of our clients are completely satisfied with the projects developed by our company, which is supported by a 5-out-5 rating on Clutch.

In particular, we once deployed custom software for a leading organization in the financial industry, which provides audit, advisory, and taxation services. This company needed a comprehensive end-to-end solution to provide hassle-free financing and loan experience to their clients.

While working on this project, we were in charge of DevOps, front-end and back-end development, UI/UX design, SRS, FRS, and post-maintenance. Our developers used Angular for the front-end part and Node.js and PHP7 for the back-end part.

After having completed and implemented this solution, our client has managed to increase their productivity by over 60%.

Four Ages Approaches to Hire Frontend Developers

We do everything possible to make the path from project idea to its realization as smooth and seamless as possible for businesses. We begin with requirements gathering to understand better what you expect from the completed application and how we can help you.

In a nutshell, here is how Four Ages handles projects, from the starting point to the software maintenance stage.

Initial communication session. This is the first step, where our clients tell more about their ideas for the project, requirements, and business goals they aim to achieve. If you don’t have any technical requirements yet, our BA specialists can outline them based on your expectations and objectives.
