Python Developer (Traveltech)

Aviasales for Business is a business trip management service and the world's first meta-search for flights for companies. We compare flight prices from different providers and offer B2C prices for businesses. In addition to flights, we also sell hotels, train tickets, bus tickets, transfers, insurance, and additional services.

With us, companies get low prices on travel services, a convenient personal account, the ability for employees to book tickets, customizable travel policies, and all the necessary closing documents for accounting.

We make business trips convenient for employees and simple for the company. Our backend is written in Python, the frontend is REST, serving 85% of the main client panel, 10% of the internal support admin panel, and 5% of the public API part.

Part of the code is responsible for interaction with the frontend and implements our internal logic, another part involves numerous interactions with suppliers and connections with other services. Tasks are planned in weekly sprints in Jira.
