ABOUT PROJECT

Highly loaded B2B payment platform for e-commerce. The platform allows you to make payments quickly and securely. The client will be able to choose as many payment providers for his site as he wants and as many as technically able to integrate them. There will also be a personal account with analytics for all contractors/buyers (where the transaction came from, what amount, or re-payment, quantitative and qualitative data).
The competitive advantage is the integration in 2-3 clicks without a developer on the client’s side and the fact that our entire solution is completely in the cloud. Development from scratch has been going on for about a year.
At present, payments are possible only in classic currency. Cryptocurrency payments may be made once the product is stable in the market.
We use only new technologies. No overtime and time trackers.

R&D team:
17 developers + service stations (4 pure backends and all other full stack and frontend). The team has a Product Manager who can be contacted independently or through Lida with questions about tasks or projects. On project 2 Backend Team Leads and reports will need one of them.
The trial period is 3 months and during this time Team Lead will be onboard and help in mastering the fintech of the product/data.

Tech stack:
Back-end: Node.js (14 version) / Express / Koa, gRPC / GraphQL / REST, Cassandra (ScyllaDB), DynamoDB, AWS, Jenkins, Docker, Kubernetes, Istio.
Front-end: React, Apollo+Federation, Material-UI, Figma + Zeplin, Cypress, Sentry.io, everything in TS (we love type generators so no need to write types by hands).

Microservices everywhere. Now there are more than 120 of them.
All daily tasks are solved with the help of JIRA. The backend team works on two weekly sprints. There are not many rallies or groomings, only daily rallies for 15-20 minutes every day at 11:00. The processes are quite flexible, so if there is a problem, the rally is scheduled based on its existence.
All doors are always open! If you have ideas for improving the code, project, or processes, then your constructive opinion is important for the company.
We have already received licenses for transactions and signed contracts with Mastercard, PayPal + payment providers. Active development for at least another 2 years. For the next 6 months, the main tasks are the integration of payment providers.
