Software Development Review from Rick Tomsic
Global business segment growth is requiring technology to keep up with the increase. Our platform is designed to be scalable and able to be implemented across several nations. We collaborated with Closeloop Technologies to work with our staff in order to scale up the programme.An whole agile team is provided by Closeloop Technologies to participate in our programme. At first, we gave them the data in hopes that they would aid in our execution. They have combined Spring Boot, JavaScript, and AWS cloud technologies.The platform is a value stream and full-suite insurance lifecycle. It is an internal iterative software programme.Working with Closeloop Technologies is simple. They pick up new roles rapidly and possess agile team abilities that are industry standard. The staff not only fits right in, but they also contribute their knowledge and perspectives, making them a vital component of the programme.

Software Development Review from Henrique Dubugras
Services that had been slow or unavailable for weeks had to be brought back up. We must bring back our vital business role. After learning about our issue, the Closeloop project manager assigned a senior database specialist to address it. Our main programmer had a direct conversation with the database specialist of Closeloop after they listened to our problem and asked some follow-up questions. Within less than two hours, the solution to our issue had been verified and implemented.

Software Development Review from Bill Rogers
We occasionally utilize outsourced resources to increase our team's ability to satisfy the commercial demands of our clients. This time, my goal was to create and enhance the products we were providing to clients. Their engineers joined our own team to work on the project, creating MetaTrader-based software for our traders. They assisted us in creating and refining a suite of services that give our clients more functionality; up until that point, the solution had been erratic and unconventional. Their most recent endeavor was the development of an income trading module. We employed a scrum methodology with sprint deliverables and agile planning. Along with narrative points, we also used our in-house bug tracking application for project and task management. Everything was really accurate.

WDI Reviews & Testimonials

Mobile App Development Review from Konrad Korobowicz
Thanks to Wdi's expertise and dedication, the music app achieved a 400% increase in downloads within the first month of launch, demonstrating significant progress and success.

Mobile App Development Review from Abdelrahman ALMULLA
wdi took the vision we had and turned it into something even better. They built this incredibly detailed app that lets users filter hotels based on things like airport transfers, car services, or other specific amenities. Travelers can also quickly spot deals or limited-time offers with just a glance.One of the coolest parts is how the app keeps guests updated when theyre checked into a hotel - whether it's on-site events or nearby activities, theyll get notifications straight to their phone. The feedback system they added is a game-changer. Guests can send questions or share thoughts right from their rooms, and they get notified the moment theres a response.

Mobile App Development Review from Aaron Birkby
We had many very clear outcomes and timelines based on our needs that were identified before the project began. They provided regular updates and progress reports via email and virtual meetings throughout the project. Typically in two-week sprints.

Frequently Asked Questions
What is responsive web design?
Responsive web design is a web design method that allows a website to dynamically adapt how it’s displayed on different devices, considering the user’s platform and screen size. This way, web developers and designers can build a single responsive version of a website instead of multiple ones for different devices. Â
When done right, responsive web design provides a seamless user experience (UX), improved load times, and, in turn, higher click-through rates (CTR) and better search engine optimization (SEO). Â
If you need responsive web design services, you can:Â
- Hire a professional responsive web design agency and outsource your projectÂ
- Develop your own project using responsive website builder software like:Â Â
- Wix, Â
- Weebly, Â
- Squarespace, Â
- Webflow, etc.Â
- Hire freelance web designersÂ
- Hire in-house responsive web designersÂ
What companies provide responsive web design services?
Typically, most web design companies also provide responsive web design services to ensure seamless user experiences across different devices. Â
Web design companies that specialize in responsive design help create responsive websites, web applications, games, and other types of web content. These companies also offer mobile SEO and UX services including on-page and off-page SEO, tag optimization, URL optimization, technical SEO, content optimization, sitemaps, wireframing, user personas, user journeys, UX design, etc.Â
How much does responsive web design cost?
The price of responsive web design agency services can go anywhere from $2,000 to $50,000 per website. The costs depend on various factors like:Â
- Size: number of website pages, page templates, pieces of content, media, etc.Â
- Complexity: the complexity of navigation, types of visual features, third-party program integrationÂ
- Functionality: whether there will be booking and scheduling services, customer portals, etc.Â
Here are some examples of typical price ranges for responsive web design and maintenance projects:Â
| Website type | Total design cost  | Annual maintenance cost |
| Small business website | $2,000 - $10,000 | $400 - $1,200 |
| Corporate website | $10,000 - $30,000 | $2,000 - $15,000 |
| eCommerce website | $5,000 - $50,000 | $15,000 - $30,000 |
| Database-driven website | $6,000 - $75,000 | $30,000 - $60,000 |
The top 50 responsive web design companies on DesignRush charge an average of $83.5/hour. Roughly 25.20% of the responsive website design companies on DesignRush accept projects with a minimum budget of less than $1,000, while 3.70% have a $50,000+ minimum budget.Â
Why should you hire a company that specializes in responsive web design?
You should hire a responsive web design agency because of the following benefits:Â
1. Better user experienceÂ
According to Google research, 53% of mobile users leave a page that takes longer than three seconds to load. A responsive web design company will optimize your website for fast loading speed, among other things, improving the user experience by ensuring that the content remains accessible and readable across all devices.Â
2. Improved search engine rankings Â
Websites that are mobile-friendly, which is the main draw of responsive web design, get higher search engine rankings. This way, you increase the visibility of your website and attract more traffic.Â
3. Sales optimizationÂ
79% of consumers disappointed with the website’s performance are less likely to make a purchase from the same site again. By improving your website design, you are increasing the chances of getting recurring customers.Â
4. Responsive website design expertiseÂ
Experienced developers with a lot of responsive projects under their belt typically deliver higher quality work.Â
5. Faster resultsÂ
When hiring a responsive web design agency, you don't need to spend time and resources to recruit and train internal web developers.Â
Here is an example of a successful project by a responsive web design company called Big Drop: a client needed to modernize its visual identity with a refreshed website. Big Drop provided intuitive user journeys, clean UI, and an information architecture strategy to enhance the client's digital presence. Â
After implementing website changes, the clients saw a 15% increase in conversion, 9% increase in page load speed, and 17% increase in on-site engagement.Â
How to choose the best companies that provide responsive web design?
You can choose the best responsive web design companies by following these steps:Â
- Define project scope: Decide on website structure, number of pages, features, and functionality.Â
- Set project requirements: Make a checklist of goals and the means to achieve them (e.g., deliverables list, timeline, communication guidelines, preferred technologies, etc.).Â
- Set a budget: Look for the best talent in a range you can afford. If you have a small budget, try expanding your search to countries with more affordable prices.Â
- Inquire about experience: Ask the responsive website design company for a portfolio and similar project examples from your industry. Â
- Check credentials: Ask for certifications in common web development technologies like HTML and CSS.Â
- Choose the development approach: Depending on the project, the company should offer an Agile, Waterfall, or hybrid development methodology and tell you about the benefits of each.Â
- Send a request for proposal (RFP): An RFP contains the project introduction and scope, technical requirements, evaluation criteria, budget, and submission guidelines. Select up to five responsive web design companies and send them an RFP.Â
- Review RFPs: Go through each proposal, compare results, and interview your shortlisted companies.Â
