Experience
Airflow Workflow Processing for Audio & Video Processing
This was used to replace Celery workers to improve their performance, decrease the company's cloud costs, and reduce the number of errors to zero. It also reduces unprocessed data during the audio and video pre-processing steps.
I managed to decrease up to $2000/month of cloud costs and be able to process over 2000 snippets per minute, with the scalability and bandwidth to process many times that amount.
Exchange Proxy for Crypto Demo
I was responsible for crafting the WebSockets back end and building the bots to simulate the market. I also did some code reviews and round-table discussions for the front end.
This project was done in Python and React, yet there are some pieces where the front-end team couldn't finish, but the features were implemented on the back end.
Later on, we had to build the actual back end in C#. We used the exchange REST APIs and WebSockets to connect with the exchanges.
Trading Automation System for a Smart Crypto Trading Company
In a nutshell, it can create various trade rules, specifically a set of order templates, and detect order updates and price fluctuation via WebSockets to proceed with the trade workflow.
Also, being able to scale itself based on the load, it can support over 30 thousand simultaneous trades.
The project was designed to support as many trade rules types as needed.
Institutional Crypto Trading SaaS Platform
Trades including:
• Ladder trading
• Alert and trigger trading
• Trading view chart able to create trades based on drawings
• Full trading (entry, stop-loss, targets)
• Ping pong trading
• Yield matrix
