Improved the reliability and functionality of backend systems. Migrated data processing / ETLs from AWS Data Pipeline to a simpler Python + RQ system (reduced complexity, easier maintenance, better monitoring). Replaced email-based alerting system with an error aggregation service. Creating repeatable, re-deployable and scalable cloud infrastructures is what I excel at. Can architect and deploy Compute, networking and data resources in fault-tolerant and highly available manner. Extensive experience in setting up the continuous integration systems like Jenkins, gitlab ci cd, github actions. Solid experience working with Ant, Maven and Shell scripting build systems which will be used as part of Jenkins to create the build jobs to automate the complete developer echo system. Have Elasticsearch experience of 4 years, very proficient with Postgres and MySQL master/slave architecture. Worked as an SRE on the Infrastructure team.
