      Software Development Review from Darren Cooper

      I previously struggled to effectively manage my finances due to the lack of a suitable all-in-one platform. Recognizing this need, I engaged Indi IT Solutions to develop a customized system tailored to my specific requirements. These included robust budgeting and forecasting capabilities, comprehensive accounting and payroll functionalities, and advanced reporting and analytics tools. Initially, I had some apprehension regarding the final outcome. However, I was pleasantly surprised by the delivered solution, which closely aligned with my vision. While minor issues arose, the Indi IT Solutions team promptly addressed them through collaborative meetings and timely implementation of necessary changes. The project was delivered on schedule, exceeding my expectations. I particularly valued the team's responsiveness and proactive approach in addressing my inquiries. Overall, I consider this to be an exceptional experience.

      Software Development Review from Sharon Robertson

      Our growing business created a surge in production that our supply chain couldn't handle. To keep up with this growth, we needed to improve our supply chain management with better web and mobile apps. We looked at different app development companies and talked to them about our needs. We ended up choosing Indi IT Solutions because of their experience and because they understood our challenges right away during our first meeting. The project took 5-7 months to complete and included features that made our supply chain management much better. The Indi IT Solutions team upgraded our infrastructure by moving it to the cloud and balancing the load on our servers. They also improved our databases and code, added new features, built strong APIs, and made sure everything was secure. Since launching the new apps, our supply chain management has become much more efficient, and it's now easier to oversee all of our manufacturing units. We're now working on adding even more features to the system to make our operations even better. Everyone on our team is really happy with the work that Indi IT Solutions did. Working with them was a great experience and there were no problems along the way.

      Software Development Review from Johnathan Carter

      In our recent construction project, the client needed a modern setup with IoT solutions to control building operations remotely. While the building was being built and the hardware chips were set up, we needed software to help oversee and control everything. IndiIT helped create this software, which boosted efficiency by providing real-time data and analytics. This allowed property managers to monitor operations, reduce energy use, and address maintenance issues proactively, minimizing disruptions. The IndiIT team carefully gathered our requirements and began with a data integration layer that seamlessly connected IoT devices with building management systems (BMS) across HVAC, lighting, and security. They also integrated a powerful real-time analytics engine capable of instant data processing, enabling predictive maintenance, trend analysis, and optimized energy use through machine learning. One of the standout features was the software's scalability, allowing future upgrades to meet evolving demands. After the successful completion of this software project, our team was satisfied. I would like to mention that the IndiIT team is an expert in delivering customized software solutions. Good job team!

      Software Development Review from Kelly Lavelle

      We hired Competenza to build a custom software tool to help manage our online bookings and product sales in one place. They designed and developed a booking system for our spa that also connected with our product store. It included custom dashboards, easy scheduling, and reports we could actually use. We saw fewer booking errors, faster checkouts, and more online sales. The system saved our staff time every day and made things easier for our customers too. They really listened to our needs and built something that felt like it was made just for us, not a one-size-fits-all. Everything was done on time and the process was smooth. Communication was clear, and they were quick to make changes when we asked.

      Competenza Innovare upgraded our platform with better video, new connection options, group ordering, and a catering tracker. They worked in clear sprints, tested across devices, and delivered on time and in budget. The backend and admin site they built make managing content easy. Communication was consistent, and they were quick to fix issues. Very organized team.

      Software Development Review from Brett Danielson

      They built a custom search tool for us. The system works well and saves us a lot of time. They keep up with our fast pace and still hit deadlines. Sometimes they even add features we didn’t request because they know it will help. Now we can look up customer info, shipments, and vendor details in seconds. We meet every week to go over what we need next. They fix bugs, but they also make the system easier to use without us asking. Our business changes fast, but they stay patient and flexible. They really listen and adapt. Everyone on their team wants to help us succeed.

We've completed the first milestone, and Artur has shown great professionalism and skill in bringing my ideas to life. He's been responsive, attentive to detail, and really listens to my needs. While the website isnt fully completed yet, the work done so far has been fantastic, and Im excited to see the final product. I look forward to continuing the project with Artur and would recommend him based on my experience so far!

      Heres the translated comment: Comment: Great job! The application looks intuitive, with a modern design and smooth user interface. The functionality is implemented at a high level: convenient specialist search, a transparent booking system, and a clear service payment structure. Additionally, I want to highlight: 1. Performance: The app runs quickly and without lags, leaving a positive impression on users. 2. Usability: The navigation logic and functionality are user-friendly for both clients and specialists. 3. Code: If the internal code is written with the same care as the external interface, its a testament to your professionalism. If there are any upcoming updates, consider: Adding ratings/reviews for specialists to build client trust. Integrating reminders through push notifications or email. Thank you so much for your contribution to the project!

      I was initially looking to develop and app like Gpay and Nevina Infotech did the development for the same and then unfortunately as per the change in NPCI guidelines to have 10million active users to tpap license to enter into UPI payment gateway fintech app, then at that point we were stuck and then finally then we decided with to launch app we 3 services by collaboration with cashe and Riskcovry and mobikiwik to enter the market by helping customer which is called as TreePAY which is a simple and secure way to manage your money. You can use Treepay to do contactless payments. Treepay is a payment platform where you can pay your Utility Bills, avail Personal loans and Insurances. Their commitment level and vision towards making a quality product. Mr. Rahim Ladhani CEO is a visionary man and was only focused on quality product development. He educates properly to client all industries are not where cost effectiveness works few industries especially IT services custom software development industries need time and investment to develop a quality product and they are very transparent for the same since day. I would surely recommend nevina infotech private limited.

      Best company I have ever worked in. I have spent 5 years as a beautiful journey with a lot of memories while working in Synsoft I never thought a single day that I need to switch and move on another firm, for me Synsoft is my other home. I gained a lot of knowledge while working in Synsoft and working with CTO Anjali Surana is the best part with me, she is not only a good CTO or can say boss but she is a great human being who understands his employees personal problems too. So for me, Synsoft Global is a beautiful journey of my life.

      This company is not good. They called me for an interview and then sent me back home, saying they would take the interview on Google Meet instead. After the interview, they told me that I was not selected. When I asked for the reason, they said they couldn’t give feedback because multiple interviews were conducted. Very bad — this is not good behavior. They are just wasting employees’ time.
