Why and How to Hire Retrofit Developers for Android Projects

Retrofit is a type-safe HTTP client that simplifies network operations in Android development. It gives developers a clean and simple way to define API requests; supports both synchronous calls and asynchronous calls; and lets you easily add custom headers, logging, and authentication.

For these reasons, many Android apps use Retrofit for API integration. It doesn’t just simplify processes, but it also enhances performance and security. When you hire Retrofit developers to work on Android projects, you’re choosing an effective and modern solution that won’t just benefit your app today, but will keep it scalable and future-proofed for years to come.

When Should You Hire Retrofit Developers?

There are many different scenarios where working with Retrofit developers can help. In short, if you require strong API integration in Android (such as in banking, logistics, e-commerce, or healthcare applications), choosing a Retrofit developer makes a lot of sense. Retrofit developers are also experienced at ensuring data integrity and security, which is vital for these apps.

The same is true if your application requires multiple third-party API integrations. Since Retrofit developers often focused on fast connections and functionality, choosing one improves API management and helps produce a better app.

This is also helpful if you’re replacing old networking code in a legacy app. By properly optimizing networking, a Retrofit developer can reduce loading times and wait times while ensuring the app runs smoothly and efficiently.

Core Skills Retrofit Developers Should Have

Of course, not all Android mobile app development teams and individuals are created equal. Before you choose to hire someone for Android development services, verify that they have the following skills:

• Deep Retrofit experience (Including experience handling requests, responses, error handling, and more)
• Proficiency in Kotlin and Java
• REST API design & integration
• Authentication and security handling skills
• Knowledge of debugging and optimizing network calls

There are also other skills that are important, such as ensuring they can properly handle integration with Room, Dagger, RxJava, or Coroutines. Choosing a developer with the right skills and experience helps you get the right person for the job and produce the best, most efficient application.

Hiring Approach: Freelancers, In-House, or Dedicated Teams

When it comes time to hire Android developers with high-level retrofit skills, there are many options available, such as freelancers, hiring an in-house team, or outsourcing to dedicated team. Of course, there are pros and cons to each of these options and it’s worth exploring each of them.

Freelancers

• Choosing a freelance Android developer is a common path. There are benefits to going this way. The first is cost. Working with a single freelance developer tends to be considerably cheaper than the other options.
• Most freelancers will charge between $25–$50 USD per hour, but this obviously varies.
• If you’re working on a quick task or doing something simple, you may have success with this route. However, there’s a lot of inconsistency in freelancers. It may take you a long time to find someone good who you can work with, and you might unnecessarily spend money on the wrong options during this time.
• There’s also the question of reliability and stability. Even if you can find a freelancer who is quick to respond to messages and gets work done properly and on time, what happens when bugs start popping up in a few months or you need updates next year? Will they still be around and willing to help?

In-house developers

• You may consider hiring an in-house development team on Android development services. This gives you a lot more control and stability.
• When you hire a team, you have them working for you full-time, so you can make sure your Android projects are progressing as you’d like them to.
• However, hiring a team takes a long time. It isn’t uncommon to spend several months (if not longer) putting together a team consisting of a mobile project manager, mobile QA specialist, and Android developers with strong Retrofit experience.
• There are also considerable costs associated with bringing in several new staff members. In addition to salaries, you also need to consider the cost of their workspaces, benefit packages, and more.
• Typically, a full-time developer will command between $95K–$120K CAD per year and you likely need several members on your Android mobile app development team.

Outsourcing

• There’s also the choice to outsource Android development to a specialized team. This is often a balanced approach that aims to include the benefits and flexibility of freelancers without the complexity or overhead of an in-house team.
• When you outsource Android development to an established team, you can bring in Retrofit specialists as needed but still benefit from greater stability and consistency than you’d get from a freelance team.
• The cost of working with such a mobile development team on an as-needed basis are also much lower than hiring in-house staff. Generally, you can expect to pay between $35–$55 USD an hour, depending on several factors, of course.

Where to Find and Hire Retrofit Developers in 2025

Much like with any Android projects or development project, it’s not just about hiring any developer, it’s about hiring the right Retrofit developer for your purposes. There are many places where you can find the people you want.

Freelance platforms

• There are many places where you can find freelancers, including Upwork, Toptal, Fiverr and more. These sites often have ratings that make it easy to determine if someone has the experience you need, and rich search functions to help you find someone with the right skills.

Local hiring in Canada

• While hiring a local team is complex and costly, there are many developers in Canada who are looking for work. In this situation, it becomes less about where to find the Retrofit developers and more about how to handle the hiring process.
• It can take months to go through the steps of posting a job, conducting interviews, narrowing down the field, and finally hiring and training.

Ukrainian IT outstaffing market

• Outsourcing your project to a skilled development team lets you work with a skilled and stable team that has the knowledge and experience needed to successfully complete your project.
• However, when compared to the costs of hiring developers, outsourcing provides considerable cost savings.
• A professional outsourced team also provides a lengthy support cycle, so you don’t have to worry about who will maintain the new software or implement changes or bug fixes. They’ll even work with you to make sure your project efficiently scales. And of course, you can hire not only an Android mobile development team working with an experienced outstaff partner, but also a single Android specialist proficient in Retrofit.

How to Evaluate Candidates and Partners

If you’re looking to hire Retrofit developers, how do you evaluate the options? Since Retrofit is a popular choice, there are many potential candidates. To properly evaluate someone you wish to work with, there are a few different aspects of their role and their experience that you’ll want to look at.

Proven Android experience beyond Retrofit

Working on Android projects often entails more than just Retrofit. After all, it is just one tool. Candidates should also handle Kotlin/Java, REST APIs, and app architecture. Ask them about their overall experience beyond just Retrofit to get a better idea of what they can do.

Portfolio or case studies

What other Android projects have they worked on? Look for examples of real apps where Retrofit was applied effectively (such as API-heavy mobile apps) and ask them what part of the work they did. Often developers work as part of a team, so you want to know exactly what they were responsible for.

Transparent code ownership

When the app is complete, who controls the code? You don’t want to end up in a situation where the developer maintains ownership over your app. Ensure you fully control the repo and intellectual property.

Long-term support commitment

Android apps aren’t a one-and-done scenario. Even once your mobile application is complete and out in the world, there will be ongoing maintenance and updates required. Talk to the developer about how they will handle bug fixes, upgrades, and API changes in the future.

Experience in fixing legacy projects

You may not be starting from scratch with Android mobile app development. If you have an older app or older codebase that you’re working from, you want to work with someone who understands this and has experience in such situations.

By doing proper evaluation in advance and making sure you know who you’re working with, you’ll have a much easier time getting your app developed and you’ll have money and stress as well.
