Our team builds back-ends that perform fast, provide secure and reliable data storage and can scale on demand to meet your business needs.

Drawing on our experience in Python, Django and other programming languages and frameworks, we will help you design the core of your web application — with an eye for availability, robustness, and great new features.

Whether your project needs a custom API, be it GraphQL or REST - our architects and senior engineers will get you covered.

Our front-end development team delivers visually rich and highly interactive front-end solutions that attract, engage and convert.

We can help you balance the stunning UI equal to the market-leading software products with the business logic of your web, mobile and SaaS applications.

With React JS in the core of our front-end development expertise, we create high performance apps without compromising your users' experiences.

Kenny R. Lienhard

CTO, Medignition Inc

We wanted to implement a new education platform that offered online courses in finance. The scope focused on the implementation of multiple user interfaces. UpsilonIT used React, GraphQL, and GatsbyJS. UpsilonIT had strong coding skills. The app had a clean codebase and complied with all specifications. They complied with our requirements for the UI. We communicated daily via Slack.

Matt Wong

CTO, Civic Connect

Upsilon’s work was always on time and met all customer expectations. Their team had an ease of communication but what was the most impressive about them is the integrity and work ethic of each member. We had a business manager, a lead architect, and a mix of senior and regular engineers. The workflow was extremely effective - the teams had a regular cadence for communication.

Zhanar Serikpayeva

Creative Consultant, Etage Group

We needed help with mobile app development, data analytics, and beacon installation to be able to collect, store, and analyze our customer data. The finished application met the requirements perfectly, with the team finding an excellent solution to collect, analyze, and store customer data. They were highly professional throughout the work, always making themselves available, and responding well to any changes.

Dmitry Tsybin

Director of Engineering, Carggo

Upsilon provided front- and backend development for an online logistics platform. The team designed and launched a business intelligence platform and ensured scalability according to customer requirements. We were most impressed by the technical background of the specialists, their meaningful approach to task accomplishment, and aspiration to deliver the results in due time. We’re also pleased with how fast the team started the development.

Amazing companies who trust us:
