      Mobile App Development Review from Daniel Ari Feldmar

      For our project on food manufacturing, we hired Rushkar. This was made possible by the agency's outstanding support throughout the project, which included proactive problem-solving, innovative solutions, and meticulous attention to detail. At first, reaching a consensus on project objectives was the biggest obstacle, but Rushkar swiftly made plan adjustments and engaged in open communication to address problems. Our business was greatly enhanced by its solution, which also improved consumer involvement. Rushkar continues to be a reliable partner for our upcoming initiatives, even though it might further improve its excellent work with faster reaction times and more service options.

      Lavit Singh's Review Sourced from Google

      This company is completely fake and untrustworthy. I spent 150+ hours working on their website, but in the end, they refused to pay even a single penny. :warning: Warning to other freelancers: do not trust this client. They waste time, exploit efforts, and do not respect the work. Stay away to save your valuable time and energy.
