      Web Design Review from Mona Kaia

      Probey Services has truly developed and presented my presence as an artist. They created a stunning portfolio and website that beautifully showcases my music, albums, and artistic journey. The branding and logo design were crafted with precision, giving my identity a strong and memorable touch. Other than that I have outsourced my Social Media to them for a year, and their social media marketing strategies have expanded my reach, allowing me to connect with my audience more effectively. The team is professional, responsive, and exceptionally creative, making the entire process smooth and enjoyable. I surely recommend Probey Services to any artist, business or any brand looking to make an impact online. May this project and review bring you all the growth and recognition you deserve.I have attached the required photography as per your specifications. Wishing you and your team great success. Hope you achieve all your goals.Thanks again for your outstanding work. I look forward to future collaborations.

      Software Development Review from Jonathan Gessert

      We partnered with Orases to develop and maintain a multi-tenant workflow management system and customer portal, tailored to streamline our customers and internal team's creation processes. Our previous systems used dated technologies, but Orases stepped in with a PHP and React solution that transformed how we plan, write, edit, review, and publish content at substantial scale. The system now fully supports our end-to-end workflow, allowing for seamless collaboration across teams while significantly improving overall efficiency.Orases exceeded our expectations by delivering a demo in just six months, with the full application live within eight months. Their attention to detail, consistent communication, and ability to stay on schedule were remarkable throughout the project. Their project management approach was highly effective, ensuring that every stage of development was completed with precision and aligned with our needs.The results have been outstanding. The new system has enabled us to increase productivity, handle more complex projects, and reduce the time spent in content quality assurance and client feedback loops. This has directly contributed to our companys growth and enhanced our ability to scale operations efficiently.What stood out most was Orases's methodical and thoughtful approach. They took the time to deeply understand our goals and delivered a solution that met both our immediate needs and long-term business objectives. Their commitment to excellence and alignment with our vision truly made a difference.Working with Orases has been an incredible experience, and their ability to provide innovative solutions, paired with their outstanding teamwork, has been a major asset. We look forward to continued collaborations with their talented team.

      Nema Semnani's Review Sourced from Google

      I'm way overdue in leaving this review. The team at Orases are the best in the biz when it comes to all aspects of app/software development, especially AI software dev. They've been instrumental in helping guide us through the ever-changing landscape of AI, since it definitely feels like if we blink, what we thought was cutting-edge in AI, becomes "old news." Orases helps us stay ahead of the curve...plus on a personal level, they're a genuine joy to work with. Highly recommend!

      RA's Review Sourced from Google

      As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.
