1. I have developed/extended features of various microservices which listen to FIX messages via messaging library and compute various stats such as pnl, vega, delta, etc and publish it to deepstream channel. Few of them publish stats on a messaging library which further listen by other microservices and they perform further operations from there. Based on requirements we have created various UI on which we display data after listening from deepstream channel.
2. Created a UI in vuejs which shows hardware and trading configuration-related information for a given server along with historical changes.
3. Designed and implemented via python and bash scripts on where to keep all daily recorded data, their sanity checks, and recovery or backfill of DB if something goes missing.
4. Initiated and completed an observability ecosystem consisting of Prometheus, Grafana, various exporters, and alert manager which monitors all our physical servers, VM, database, switch, and VPN. It gives alert on MS Teams or email and also perform actions to fix the issues if required.
5. Automated various tasks such as making a server ready for trading purposes, installation, various configuration management, etc via Ansible, and python, bash scripts.
6. Pioneered many ideas such as having a local pypi server and using python scripts as a module. Development, testing, and production of microservices in docker using CICD pipelines, etc.
