At Supersourcing, we believe that to achieve success in building a Unicorn startup or a digitalized enterprise product, it is essential to have experienced and certified Xamarin developers on your team. That's why we put our applicants through a rigorous interview process, and only the top 1% make the cut.

Hire Xamarin developers from Supersourcing, who have a wealth of industry experience and have successfully completed a variety of complex projects, including software, websites, and apps. When you hire Xamarin developers from Supersourcing, you can have confidence that your team will be able to hit the ground running and deliver top-notch work from the start.

Immediate Availability

Our platform provides access to immediately available Xamarin developers, allowing you to quickly build the team you need without waiting weeks or months. In reality, using our platform to hire 1–10 developers only takes three days or less.

No Freelancers

While freelancers can be a suitable choice for certain short-term or one-off projects, such as content creation or logo design, they may not be the best option for more complex, collaborative projects. Many companies have had negative experiences with freelancers, particularly when using freelance platforms, and it can be risky to rely on them for in-depth involvement in a project.

At Supersourcing, we understand how crucial it is to have an experienced Xamarin developer working on your project. That is why we exclusively employ full-time developers and never independent contractors. Your project will receive the undivided attention of our developers, who are totally committed to it. You have the option to hire them on a full-time contract without any hassles following a six-month trial term. This gives you the opportunity to "try before you buy" and ensure that the team is a good fit for your needs before committing to a long-term relationship.

Certified & Verified Xamarin Developers

While it may be challenging to find and hire Xamarin developers who are highly skilled and reliable among the pool of talent on various hiring platforms, Supersourcing makes it easy. We ensure that all of our Xamarin developers are certified and verified through multiple checks to guarantee that they have the expertise and experience required to deliver high-quality work.

In fact, only the top 1% of applicants are able to pass our rigorous interview process. Our commitment to quality has paid off - we have over 700 positive reviews, and a 99% customer satisfaction rate and 95% of our business comes from repeat customers.

When considering potential Xamarin developers for your project, it is important to consider their past experience and expertise in order to determine their suitability. We gather various data points to help you make an informed decision when you look to hire Xamarin developers. These include the industries in which the developer has worked, the stages of product development they have experience with, who they have reported to in the past, and their patterns of work, including whether they contributed ideas and helped design architecture. All of these factors can help to determine the developer's level of experience and expertise and whether they will be a good fit for your project and team.

  • Industry experience:

    By evaluating the industries in which a developer has previously worked, such as Fintech, Healthcare, Loan management, Dating, SaaS, and IoT, we can assess their familiarity with the specific challenges and requirements of your industry and determine their suitability for your project. Experience working on similar projects in your industry can indicate a developer's understanding of the sector and their potential to effectively contribute to your project.
  • Project Stage:

    To understand the depth of Xamarin developer's experience, we inquire about their involvement in different stages of product development, including the idea stage, growth stage, multi-location expansion, and PMF stage. This information helps us determine if the developer has the skills and knowledge to handle projects at various stages of development and how well-suited they are for your project.
  • Reporting structure:

    We also ask developers about their past reporting structure, including who they have reported to, such as clients, CTOs, Sr. Engineers, or others. Developers who have reported to CTOs or other high-level leaders in the past may be more experienced and proficient due to the additional responsibility and leadership opportunities that such positions often involve.
  • Contribution:

    We seek to understand developers' patterns of work, including whether they simply complete assigned tasks or also contribute ideas and assist in designing architecture. This information helps us evaluate the quality of their work and determine what role they would be most suitable for within your team.

Detailed Profiles

Traditionally, the information available about a potential hire is limited to what is listed on their resume, which may not be enough to fully assess their suitability for your project. At Supersourcing, we offer a more comprehensive solution by providing digital resumes for our Xamarin developers that include not only their technical skills and project experience but also assessment scores and an introduction video.

This allows you to get a better understanding of the developer and their abilities before making a hiring decision. Our goal is to make the hiring process as efficient and effective as possible, which is why we are working on creating detailed profiles that include the results of our pre-vetted interviews, past work, and quality scores. This way, you can hire Xamarin developers that are the best fit for your project without wasting time on unnecessary interviews.

24/7 Human Support, No Bot!

When you need support beyond the initial hiring and onboarding process, it is important to have access to real people who can assist you immediately rather than relying on ticket-based support or automated responses.

At Supersourcing, we prioritize this type of personalized support by assigning a dedicated account manager to our Xamarin developers. These account managers are experienced in handling large accounts in your specific technology and industry, ensuring that you have access to expert support whenever you need it. We believe that our commitment to customer service sets us apart from other providers in the industry.

Q&A for Hiring a Remote Development Team

Is it accurate to say that in-house teams are more productive than offshore development teams?

Contrary to what is commonly thought, studies have indicated that remote development teams often see an increase in productivity. This could be attributed to the flexibility of creating one's own schedule, improved communication, reduced stress, and increased motivation. Research has found that remote development teams have reported 77% more productivity than teams that work on-site.

Does bringing on a remote development team affect the work environment and corporate culture?

A remote work setup does not need to hinder team cohesion or corporate culture. Through the implementation of efficient communication and collaboration tools, remote teams can still foster strong bonds and connections with each other. It is crucial for organizations to provide such tools when recruiting remote developers, to ensure they stay connected to their coworkers and the company culture.

Is working with a remote development team a cause for concern about data security?

Data security is of paramount importance when working with any team, particularly remote teams. To safeguard sensitive data, it is essential to have all team members sign strict non-disclosure agreements (NDAs).

Having a remote development team has several benefits. This can include exposure to a larger talent pool, cost savings on office space, increased flexibility in scheduling, and higher productivity due to less interruptions.

How to Maximize Post-Hiring Productivity of Remote Xamarin Developers?

Outline Duties and Responsibilities:

It's vital to understand the obligations of both the employer and employee when working remotely. Remote workers may need some time to acclimate to the company's code, so it is important to not have high expectations in their first week of work.

Familiarize with the Business:

To ensure the remote worker has a good understanding of the business, conduct induction sessions that align with the company's values and mission.

Provide Documentation:

By sharing documentation, such as coding standards, beforehand, the remote worker will have a better understanding of their role and how the system operates.

Express Gratitude:

Expressing appreciation through emails or messages can be an effective way to motivate and inspire remote workers.

Allow for Anonymous Feedback:

A suggestion box can provide employees with an avenue to express their issues and concerns anonymously, fostering an open and welcoming work environment.

Set Ambitious Goals:

Setting internal targets that are slightly above what the team is capable of achieving can motivate and challenge them.

Establish Communication Standards:

It's crucial to establish ground rules and standards for communication between the in-house and remote teams.

Regular Check-ins and Feedback:

Regular check-ins and feedback loops allow managers to track progress and identify the needs of their remote workers, and offer support and advice.

Organize Company Meetups:

Company meetups, whether work-related or for fun, can enhance morale and engagement among remote workers by enabling them to collaborate more effectively and bond.

Remote Hiring Fraud- How to Avoid such Risks?

Lack of Qualifications

When considering remote developers as hires, there are several potential issues that employers need to be aware of. One of these issues is a lack of qualifications, which can lead to wasted time and resources on a candidate who is not a good fit for the job. To prevent this, it is important for employers to verify credentials and skills through portfolios and certifications.

Billing Fraud

A potential issue when working with remote developers is billing fraud, in which employees are invoiced for more hours than they actually worked. To prevent this, it is important to establish clear agreements regarding expected hours and rates, and to monitor progress through regular time-tracking submissions.

Fake Resumes

One of the potential challenges when hiring remote developers is encountering falsified resumes, where candidates inflate their experience or expertise. To address this, employers should conduct comprehensive background checks, verify candidates' education and work history, and follow up on references to ensure accuracy of the information provided.

Misrepresentation of Skills

Another potential issue when recruiting remote developers is a candidate's misrepresentation of their skills. A candidate may do well in an interview but lack the necessary abilities for the role. To ensure that only qualified candidates are hired, it is essential to assess their technical skills through testing before making a hiring decision.

Poor Communication

Effective communication is crucial when working with remote developers, as it enables them to comprehend project requirements effectively and avoid any confusion. Miscommunication can become a challenge when working remotely. One way to overcome this challenge is by assigning a dedicated account manager to facilitate clear communication, this will help to minimize any misunderstandings.

Outdated Technology & Middlemen

Another potential concern when working with remote developers is the use of outdated technology or intermediaries. The use of outdated technology may hamper the ability to scale and make changes promptly. Communication may also be hindered when intermediaries are involved. To mitigate these issues, it is essential to collaborate with developers who are proficient in current technology and best practices, and to establish direct communication with them, as this will help to avoid any such problems.
