Azumo Reviews & Testimonials

Software Development Review from Michael S.
We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

UI/UX Design Review from Anonymous
Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

Software Development Review from Anonymous
Thanks to Azumo’s work, our product is now more scalable, optimized, and ready for a growing user base. Their team has managed the engagement effectively, keeping us updated and addressing any challenges along the way. We’ve appreciated their constant availability and proactive communication.

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.

Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.
John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Mobile App Development Review from Matic Debelak
Workstream 1: research and product strategyWorkstream 2: ETP release Technology : Vendor use Flutter framework, which allows one programming language and one codebase to create two different apps (for iOS and Android). Clearly defined roles and responsibilities, communication is clearly and respectfully, very effective project methodology, trying to understand every time how their activities fits into mission of Modra zavarovalnica, respect each member of team, etc.

Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
Web Design Review from Anonymous
Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

Web Design Review from Patrice Archer
They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.
