      Software Development Review from Matt Hobbs

      I am writing to recommend EffectiveSoft, a technology consulting company that has been providing services to Canopy for the last four years. During this time they have consistently demonstrated professionalism, expertise, and a strong commitment to meeting deadlines for our business outcomes.. Canopy’s mission is to improve the financial resilience of UK renters, and support the Agents and Landlords they rent from with our powerful referencing platform. EffectiveSoft has been a key partner, working with us to deliver our product and engineering roadmaps as we continue to grow and scale. Their skilled team of engineers has worked to understand our unique product needs and deliver quality platform increments following agile principles.One of the most impressive qualities of EffectiveSoft is their ability to respond flexibly to our changes in direction, and meet evolving delivery deadlines, overseen by Kirill Makarenko, our technical project manager. Kirill and the team’s strong work ethic, capability and diligence has been crucial in the successful execution of our projects. It is rare to come across an external development team that remains steadfast in its commitment to service standards and business continuity, and here EffectiveSoft have excelled. Based on our experience, I would highly recommend EffectiveSoft for any organisation seeking technology delivery services. Their dedication, responsiveness, and commitment to delivering results make them an invaluable partner.

      WillowTree, located at the Wool Factory in Charlottesville, VA, is housed in a beautifully restored historic building featuring modern, thoughtfully designed office spaces. I had a fantastic experience working at WillowTree Charlottesville, enhanced by an excellent on-site café and a charming outdoor coffee shop. The Wool Factory itself is an iconic landmark, blending historic character with contemporary architecture.Its central location provides easy access to many of Charlottesville’s attractions, including historic buildings, museums, shops, restaurants, hotels, and the mall. WillowTree is an outstanding company to work for—they truly value their employees and provide a top-tier in-office experience.

      Eric Wexler's Review Sourced from Google

      Working with Big Fish App Development was a fantastic experience. Sara and her team were professional, helpful, responsive, and incredibly easy to work with throughout the entire project. Building an app or software can be a stressful undertaking but Sara really takes an organized approach and explains the process step by step. Her deep knowledge and expertise really showed, and she consistently met deadlines while being flexible enough to work at whatever pace was needed.Big Fish was thorough, and always one step ahead — often thinking of things I hadn’t even considered, which made a huge difference in the App. Her input during the development process was invaluable.I highly recommend Big Fish to anyone looking for a skilled and dependable app developer. If you are coming into this with little AppDev knowledge, just know that Big Fish is fair and trustworthy. I couldn’t have asked for a better team in bringing my app and ideas to life!

      Join at your own risk.My experience with Mantra Labs Pvt Ltd was disappointing. Payments were often delayed — sometimes up to 3 months — even while actively working. After leaving the company, the full and final (F&F) settlement has still not been processed, even after 6+ months.Despite flashy LinkedIn posts about AI and innovation, the internal management and employee treatment tell a different story. Think twice before joining.

      Pritam Roy's Review Sourced from Google

      I had the privilege of working at Mantra Labs, and I must say, it was an incredible experience from start to finish. As my first company, I was grateful for the opportunity they provided me to work with Python and Django, which significantly enhanced my skills and knowledge in these areas.Like any organization, Mantra Labs had its pros and cons, but I genuinely felt that they prioritised the well-being of their employees. They offered decent employee perks, such as flexible working hours and health insurance, which were on par with other organizations of similar structure.What truly made my time at Mantra Labs remarkable was the friendly and supportive environment created by my seniors and peers. As a fresher, I consider myself incredibly fortunate to have had such helpful colleagues who guided and mentored me along the way.If I were to point out one area for improvement, it would be the lunch facilities. Having a dedicated lunch stall or subsidized lunch options would have been great, especially for someone like me who was not from Bangalore and had to search for suitable places to eat every day. Nevertheless, I understand that this is not a necessity and doesn't significantly impact the overall experience.I owe a great deal of my personal and professional growth to Mantra Labs. The opportunities I received and the support I encountered played a significant role in shaping me into the person I am today. I am immensely grateful for that.In summary, my time at Mantra Labs was a five-star experience. I would highly recommend this company to anyone seeking a nurturing and growth-oriented work environment.
