      This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.

      eCommerce Development Review from Luc Vlekken

      We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.

      5.0★
      IT Services Review from Rhosel Dayrit

      My top 3 things about TruAdvantage:1) The single biggest benefit is Security. Since we are a medical field office, our primary concern is securing patient’s files and account information. Second would be backup. Since most of our work is online it is important to have back up on all files electronic and non-electronic.2) Customer service is excellent and dealing with our issue at a moment’s notice is beyond expectation.3) I would highly recommend for them to try it out. they will see a big difference in the proficiency of work, the team itself and the care to their customer’s need.

      We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

      We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

      For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

      One of the largest and fastest growing IT services providers in the country. Knowing I can call the support desk 24/7 for solutions, when we deal with real deadlines with real consequences, makes a huge difference for me as well as our staff.And, for the most part, we don't have to call the support desk because everything works. The only times I have to reach out is when we hire a new person, or add a new service or license. They are very pro-active and results oriented.

      I was recently interviewed for an SAP CO position at Jade Global. The interviewer requested me to turn on my video, which I did. However, when I asked if they could do the same, they declined.If an interviewer expects the candidate to be on video, it is only fair and professional for them to do the same, fostering a more transparent and respectful interaction.
