Software Development Review from Anonymous
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.

Software Development Review from Anonymous
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.

Kanda Software Reviews & Testimonials

Software Development Review from Alex Koifman
I've used Kanda's services for years. They're reliable and their work is of high quality. I'd recommend them to anyone looking for a partner in software engineering initiatives.

Mobile App Development Review from Andrew Duggan
Kanda proved to be an exceptional choice for our development needs. They were much more [of] a partner to our startup than a vendor. The entire team treated our project like it was their own company, and the results showed that. Our customers were extremely please[d] with the desktop and mobile applications. I would definitely recommend hiring Kanda for any and all of your development needs. (Verified via email)

Software Development Review from Alan Bugos
We have worked with Kanda Software for over two years and [are] very please[d] with the quality of work, cost-effective approach in resourcing team members, and the expertise they bring to solving very complex development challenges.

Intellectsoft Reviews & Testimonials

Software Development Review from Harshal Chhajed
They have highly skilled support staff for faster resolution which leads to customer satisfaction. Also, it has many features including IoT and blockchain apart from regular software development. If there are any changes in the scope of the project at a later stage, it can prove quite costly and also difficult to accommodate last-minute client-side scripting changes. They are versatile, cost-effective, and offer quick customer support. They offer a very customized software development tool where business needs can be addressed. It is very cost-optimized and hence can help generate good returns for business investment.

K-Optional Software, LLC Reviews & Testimonials

Software Development Review from Michael Levy
Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Software Development Review from Jane Smarovozova
We collaborated with K-Optional to develop a custom inventory management dashboard tailored for real estate clients. We provided the creative vision and detailed designs, while their team focused on the software development, ensuring that every element was implemented perfectly. We worked hand-in-hand flawlessly, resulting in a sleek, user-friendly interface that not only looks great but functions seamlessly. The synergy between design and development allowed us to deliver a product that exceeded client expectations, combining aesthetics with powerful functionality.
