      Software Development Review from Daria Stolyar

      We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down. Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.

      In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

      Asim Chowdhry's Review Sourced from Google

      I looked into different solutions for Analytics & dashboards for our organization to help senior leadership make informed decisions based on dispersed data we harness in various systems. Being a Microsoft shop, narrowed the choice down to Power BI as a tool to design key dashboards. After talking to different vendors to assist us with this project, we decided to work with Whitecap. It was the best decision I made. Daryl Yanga was assigned to work with us on this project. Daryl & my team had several meetings with the key stakeholders to understand requirements for this project and narrowed down the key KPIs for the 2 dashboards. Having technical expertise inhouse, my team designed the data model and back-end data structure, while working very closely with Daryl on key deliverables. Using Agile practices & keeping the stakeholders involved at every major milestone, the dashboards were delivered on time and within budget. Also, as per agreement knowledge transfer was done to my technical team to help us support ongoing development & maintenance. Although continuing development and maintenance is done inhouse, we still have an ongoing relationship with Whitecap to work on any future projects and/or for any assistance required. I would highly recommend Whitecap!
