      Techforce working on the transition of our website name from Grande Exhibitions to Grande Experiences. The project involved the creation of a clone website where we could apply the new brand and update all content to reflect the name change before pointing the new and old domains at this new site.

      Web Development Review from Fanny Gotschall

      Bhavin is brilliant, and the project's success is largely because of his personal involvement. Over recent months, Fanny Gotschall Studios collaborated with Bhavin in the role of art director for one of its top Midwest clients. While the client had a clear creative vision, Bhavin and his team at Techforce Global consistently executed it to perfection. For every scope change, Bhavin had the appropriate team and ensured all parties were aligned. (Verified via email)

      I would like to share feedback on the work of the specialists from Azati Software. Our teams jointly participated in the development of several different web applications. The projects had tight deadlines. The frontend development team from Azati quickly immersed themselves in the work and completed all assigned tasks within the established timeframe. It is a pleasure to work with a team that has well-developed not only hard but also soft skills. I sincerely look forward to further fruitful cooperation.

      Highly professional and reliable web development team! Webotixs did an outstanding job building our ecommerce website for Mexicon Group. The design is clean, modern, and fully mobile responsive. They set up all 5 product categories Beauty, Beverages, Household Essentials, Personal Care, and Vitamins & Supplements with proper product listings and smooth navigation. The website loads fast, looks great on all devices, and has a very user-friendly shopping experience. They also handled the complete setup including domain, hosting, and payment integration. Delivered within the promised timeframe and were very cooperative throughout the entire process. Would definitely recommend Webotixs to anyone looking for a professional ecommerce website at a great price. Thank you for the excellent work!
