- Writing new API endpoints and performing code reviews.- I successfully integrated and updated implementations of various third-party systems such as Stripe and Mixpanel into our platform.- I've been involved in writing and optimizing Django ORM queries within endpoints for our Analytics dashboard.- On the Airflow side, my responsibilities include designing robust data pipelines and integrating various Crypto wallets and exchanges into our system.- I implemented an optimization strategy for importing Binance wallets. Instead of using the Binance creation date as the starting point for fetching transactions, I utilized the first transaction timestamp. This approach significantly reduced the number of calls made to the Binance server, resulting in a 50% reduction in import time for more recent wallets.- I developed a Binance API client that utilized sessions for API calls, effectively reducing the number of TCP connections established with the Binance server.

- I was actively involved in the development and maintenance of WooCommerce plugins for the WooCommerce Plugin Marketplace.- Added new features, fixed bugs and refactored code for plugins already listed on the marketplace.- One notable project I worked on involved creating a cryptocurrency payment gateway for WooCommerce. This innovative plugin facilitated crypto payments on websites, allowing customers to make payments using their Metamask and Binance Smart Chain wallets.
