A backend for desktop applications ReviverSoft
ABOUT THE PRODUCT:
A set of desktop utilities and graphic editors under a single brand.
WHAT WE DID:
The product is used by millions of subscribers, and the whole backend was designed to handle the high load. The backend services are handling the majority of business flows, such as licensing, authorization, data management, AI, etc. The service development is based on Scrum and other agile techniques we’ve been using for more than 5 years. Microservices architecture was chosen as a foundation. As it grew, the infrastructure improved.
Currently, we have achieved the following results:
- We have implemented a CQRS pattern
- We have made the infrastructure fully auto-scalable
- We have introduced development by microservices
We have covered the system with unit, integration, and auto-tests, which unlocked continuous delivery.

Real-time task processing systems
ABOUT THE PRODUCT:
A platform for quick access to services in hospitality that instantly delivers a client’s demand to staff by real-time request routing.
WHAT WE DID:
The Techstack team built the product from scratch, starting from the idea. We have built the following apps and units:
- Two cross-platform mobile apps built with PhoneGap and migrated to React Native
- A progressive web version of the app on reusable components between React Native and React
- A web dashboard build with Angular 7
- A real-time backend built with Node.js and Socket.IO.

the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the CEO and a principle founding member for Savage Bureau, a brand and design agency based in San Francisco.
What challenge were you trying to address with Techstack Ltd?
They’re assisting us in building a robust web application for a big client. The application is basically a robust event calendar for a large segment of the population to see the company’s events, which they do a lot of. Because of the pandemic, it has become increasingly important for them to give people access to these events via virtual platforms. This company originally came to us with what they had done internally, but it couldn’t support the volume of traffic.
What was the scope of their involvement?
Techstack Ltd augments our development team and they’re responsible for helping us code the backend of this web application. The app is for a large global audience, so it allows the translation of eight different languages and needs to sustain a heavy user base.
What is the team composition?
There are two account teammates that we’ve been primarily interfacing with and then two full-time developers that are contracting with us.
How did you come to work with Techstack Ltd?
We were looking for everything from individual contractors to small and mid-sized development shops. We came across their website and set up an initial meeting and then decided to proceed after verifying their skillset.
How much have you invested with them?
This engagement will probably be about $30,000.
What is the status of this engagement?
We began working together in October 2020 and the relationship is ongoing.
What evidence can you share that demonstrates the impact of the engagement?
We’re very happy with Techstack Ltd. The team is proficient in all of the processes that were advertised, as well as proficient in terms of the development language, platform, and skillset. They quickly proved their expertise.
How did Techstack Ltd perform from a project management standpoint?
Despite the time difference, they’re extremely responsive and communicative. They communicate clearly, articulately, and deliver on the things they say they’re going to deliver on. Our development team has direct access to the developers and they have regular check-ins to discuss code. The team is efficient and work diligently across timelines to meet and exceed the deadlines that we’re working against.
What did you find most impressive about them?
My tech director is very finicky when it comes to code and he won’t tolerate sloppy code. His approval is a testament to the fact that they’re writing good, clean code and they’re fast.
Are there any areas they could improve?
No, we’ve been very happy with them.
Do you have any advice for potential customers?
Some people can be afraid of experiencing a language barrier, but nothing here is lost in translation.
Techstack Ltd is proficient in all of the processes they advertised, quickly proving their expertise. They have excellent and timely communication always remaining responsive. They work diligently across timelines, meeting deadlines.
