Dreamsoft4u Reviews & Testimonials

eCommerce Review from Adil Abbas
We were not looking for one specific task to be done. We hired Dreamsoft4u for many different tasks. For our existing platform, some features were to be added. This was one task. Next, we wanted to build our own e-commerce platform for our own products with a crypto-checkout feature. Next, we also wanted to build a prediction platform. Among all the requirements that we had, our major requirement was the e-commerce platform that we needed for our own products. Also, we needed a crypto checkout platform for the same. The design is very minimalistic. Thus, giving a very user-friendly experience. The product will show its USD price and during the checkout, its crypto price will be shown. We have also added some new features to our existing platform. We were able to host the website successfully. The whole project, despite so many things to be done, went smoothly. It was a completely hassle-free experience. The team worked in coordination. We had to stand up calls on a daily basis to discuss the upgrades, improvements and progress. The team at Dreamsoft4u is very flexible to work with. So far, we have not felt the need for any sort of improvement for Dreamsoft4u.

Mobile App Development Review from Dipanjan Chatterjee
We hired Dreamsoft4u to rapidly build an on demand liquor delivery app - that also serves an alcohol marketplace, liquor store locator and a rare source to find alcohol. The product they developed is not just a stereotype on demand delivery mobile app but it is the best liquor store locator and a rare source to find alcohol. Our dream was to build a platform that caters to enterprise customers who are looking to procure alcohol online for events and special uses. We signed a contract with them to develop an on demand liquor delivery app for both Android and iOS platform. We want to build a product that serves as beer finder and alcohol tracker wherein users should be able to shop a wide selection of liquor from multiple local stores in one go. Further, they should also be able to compare prices, deals from the liquor stores nearby their location at fingertips. The most impressive thing about Dreamsoft4u was everything got designed and developed inhouse by experienced developers. We had rough draft of wireframes but they improved it with their designing and added the elements of branding and personality. The app got launched on App Store and Play Store. Since the launch of this version of the app, we have gotten all positive feedback. Not only users are admiring the app design but we are also experiencing good amount of downloads with high user retention. Cant find any areas for improvement , they have been fantastic throughout our journey.

IT Services Review from Toby Cosgrove
We realized that there is a direct correlation between Instagram posts and online sales of our product. Hence, we met Dreamsoft4u with our vision to create a visual planner for Instagram from a designers and editors point of view that boosts and protects any ecommerce brand. The task looks simple but to build such tool is indeed full of complexity and throws challenge. We started with a pleasant kick-off meeting with the account- and project manager to make sure all involved parties are on the same wavelength and inline with our vision. They provided Basecamp, JIRA, Notion, Figma as a collaboration tool for daily communication, questions and updates. Earlier we wanted to develop a planner but they advised us to go ahead with incorporating scheduling feature too which is like an icing on the cake. The product got launched before time and received pretty impressive feedback from our community. Hardly any other development companies can meet deadlines before due time and that too without compromising on quality and impacting on your pockets. Their technical team is active and goes deep into the solutions. The team possess high level of integrity and passion for quality delivery, The product they have developed is launched and we received pretty good response. The impressive facts about them are commitment to delivery, understanding of customer requirements, and quality of development. Cant find any areas for improvement, they have been awesome throughout our journey.

CoSpark was a true lifesaver for our online journal with a bug in its signup code. Heral Patel was prompt, courteous, helpful and economical. The signup now works great! We will be using CoSpark again.
Jonathan Lopez's Review Sourced from Google
A few years ago, I reached out to Heral for custom Mailchimp newsletter development based on AnnexCore's great online reviews in addition to their Mailchimp expert accreditation. He was a pleasure to work with, very professional, and even finished the job early with no revisions necessary.I refreshed our newsletter a couple weeks ago and then contacted Heral to execute the project. He responded to me right away, started the task immediately and completed the project ahead of schedule once again. This design was slightly more complex than the previous one, so Heral consulted me on a few issues to remedy a minor issue I had with the design. It was another great experience working with Heral and Annexcore. I recommend AnnexCore and Heral for any email marketing consulting and will definitely be using them in the future.
Support Contact's Review Sourced from Google
AnnexCore was fantastic to work with and produced an outstanding marketing campaign from start to finish. The service and response time was instrumental in completing our project on time considering our tight time frame. I will be collaborating in the future with AnnexCore and recommend them strongly.Pat M Red Capture
