    That's why at Supersourcing, we take into account the industry you're in and prioritize MERN Stack Developers who have experience working on similar fintech or other business initiatives.

  • Project Stage:

  • Reporting to Whom:

    When looking to hire MERN stack developers, one of the most important factors we keep in mind is who they reported to previously.

  • Contribution:

    To make sure our MERN Stack developers are the right fit for your needs, we assess their past experience in all aspects.

    We look at which industries and product stages they've worked in, as well as if they're more of a task-completer or an idea-collaborator.

Supersourcing Vs Freelancers Vs Other Providers

Factors Freelancers/Others Supersourcing Developers
1. Quality With freelancers, you don't always know what kind of expertise and experience they bring to the table. Hiring someone without proper vetting could mean risking a project's success. Supersourcing MERN Stack developers are top-notch, pre-approved experts who have access to everything they need in order to stay ahead of the curve. Connecting with us guarantees exceptional results on every project you take on.
2. Security When freelancers take on multiple projects they can be a major threat to your confidential business data. With information constantly circulating between clients and contractors, the potential for security breaches is real. Supersourcing is dedicated to safeguarding your data. Our experienced MERN stack developers come with the assurance of confidentiality due to strict NDAs and risk-free solutions — so you can trust us every step of the way.
3. Cost Hiring freelancers might seem like a good idea to save money in the short term, but it can end up costing you more if your project isn't completed. Since they're unassociated with any company or organization, freelancers don’t assure long-term commitment and may leave projects unfinished unexpectedly resulting in costly delays. Get world-class development results without the hefty price tag by hiring developers from Supersourcing. Our clients save up to 70% on their development costs compared to in-house resources - that's a huge advantage for any startup or enterprise looking for high quality work at an affordable rate.
4. Onboarding With freelancers, there's always an inherent risk of them dropping out midway through a project- even after all the onboarding has been done. That can be frustrating and costly in terms of time and money wasted. If you have a project that needs to start ASAP, our developers are ready and waiting. With immediate availability, they'll hit the ground running on your timeline – so no worries about any delays.
5. Motivation Working with freelancers can be great for many projects, but it's best to remember that their priority is often financial reward rather than creative collaboration. This means the relationship may become a simple business transaction where emphasis lies on getting tasks done quickly and efficiently instead of creating something special together. At Supersourcing, our goal is to bring together passionate and creative minds who are looking to make a difference. Our alternative approach of flexibility combined with collaboration empowers developers to think outside the box and contribute with their creative potential while working on projects that meet the needs of any client.
6. Commitment Freelancers don't always stay for the long haul - leaving your project in a precarious position and risking costly delays. Without a long-term commitment to you and your goals, you may have to change plans h mid-way through your project. At Supersourcing, our MERN Stack developers are locked in by comprehensive contracts. This means you can be confident that your project will reach the finish line without delays and with quality results.
7. Negotiation Working with freelancers can be a great way to get the job done quickly and efficiently. Unfortunately, once you become dependent on them, they may unexpectedly increase their rates which could require scrambling for extra budget or finding new help altogether - both disruptive and costly scenarios. At Supersourcing, we partner with you to find the perfect MERN stack developers for your project needs - from cost-effective solutions designed specifically for startups to highly specialized expertise that meets enterprise demands. We'll make sure each engineer is tailored to fit within your budget.

Remote developers have the power to deliver astounding results, with research showing they can be as much as 77% more productive than in-house teams. Working remotely brings a variety of advantages like improved communication, increased focus and lower stress levels – all leading to greater happiness among development teams!

Do Remote Teams Affect Team Spirit and Company Culture?

Leveraging technology to bridge the gap between physical distance is a crucial aspect of successful remote teams. Many companies are striving to provide employees with innovative communication and collaboration tools, knowing that this will foster meaningful connections even over long distances. By doing so, they're creating vibrant company cultures among their distributed workforce - enabling them to form cross-continental bonds.

Do Remote Teams Compromise Data Security?

Companies looking to hire remote development teams must prioritize data security. NDAs and other agreements should be put in place as strong safeguards against possible misuse of confidential information, while also investing in robust IT systems with effective password management strategies and two-factor authentication for optimal protection. Supersourcing does that for you before you hire remote developers from them.

What Are The Pros Of Hiring A Remote Development Team?

Working with a remote development team opens up exciting possibilities, allowing organizations to access top talent from around the world at an affordable cost. Productivity is improved thanks to better organization and more flexible working hours that accommodate time zone differences.

How to Maximize Post-Hiring Productivity of Remote MERN Stack Developers?

Explain Duties & Responsibilities

Establishing a strong connection between employer and remote employee is key to successful outcomes.

Rather than jumping straight into rapid-fire requests, take it slow - give them the opportunity to learn your workflow before expecting peak performance.

Give Time for Business Understanding

Welcome your remote development team into the fold with an induction session! Let them know what you’re striving for, and how their skills can help reach those goals.

By establishing a common purpose from the get-go everyone will be able to join forces in order to create something amazing.

Share Detailed Documentation

Get your remote developers up to speed with the right tools and expertise.

Give them access to vital documentation that will provide a solid understanding of how the system works, so they succeed from day one.

Send Appreciation Emails

Showing your team appreciation is one of the best things you can do to keep them motivated. A simple "thank-you" goes a long way in encouraging and inspiring employees, giving recognition for their efforts with minimal cost.

Create a Suggestion Box

Creating an open, honest dialogue among colleagues fosters a safe and inclusive workplace. A suggestion box provides the perfect platform for employees to share their ideas without fear of critique or repercussion from management.

Ultimately, this kind of atmosphere allows everyone to express themselves authentically while strengthening relationships between members on the team!

Set an Internal Target

Managers can help their teams reach new heights by setting achievable targets that encourage them to go beyond what they know.

Providing guidance and support throughout the process is key; when done right, everybody wins.

Set Ground Rules

To ensure your remote team succeeds, it's essential to establish solid ground rules. Setting standards for communication and expectations will help keep everyone on the same page.

Additionally, choosing a default timezone is beneficial in coordinating activities such as deadlines, meetings and messaging regardless of international borders or locations - all working towards one collective goal.

Maintain Regular Check-ins & Feedback Loops

Managers of remote workers can help connect, understand and nurture their teams.

Regular check-ins foster engagement, boost morale and provide the opportunity for managers to offer advice that can help employees reach new heights in their roles.

Conduct Company Meetups

Working away from the office can have its benefits, but staying connected is key for success.

Company get-togethers bridge communication gaps and encourage camaraderie with fun activities - resulting in a more productive remote workforce.
