Senior Python Engineer - 28579

I have eight years of experience in software development. Most of the projects I was involved in were developed from scratch. The biggest project I am proud of is a payment system aggregator for a specific market, which I cannot disclose. It was an SOA, with services on Flask, a monolith on Django, and Kubernetes for scaling. Also, on this project, I developed the client-side for POS terminals with integration to the main service. In the end, it looked like IBOX terminals with a bunch of payment systems + crypto.

The replenishment of crypto wallets through the generation of one-time wallets (to which we have all the keys and can monitor their balance) and a QR code for printing, so that the client can replenish this one-time basket, and we catch a webhook and then transfer the crypto from the one-time wallet to the one specified by the client.

Also, we made it possible to withdraw crypto by converting it into fiat. Again, through the generation of a one-time crypto wallet, printing a QR code for the client with the address of this wallet, and issuing cash at the rate at the moment, after receiving a webhook.

Based on the Proof of Work concept, all transactions must first be confirmed by a certain number of nodes, but in this case, we did not work with the blockchain directly, but integrated with Coinbase, which guarantees the authenticity of transfers by sending webhooks to consumers.

Have you seen the crypto wallet replenishment terminals in Odessa? That could have been us, but we deployed in another market ;)
