As a Technical Lead at LinkedIn, I spearheaded a high-impact server performance team over the last four years, focusing on troubleshooting and rectifying performance issues within predominantly Java applications. My key responsibilities included leading the migration of the entire fleet from JDK8 to JDK11 and subsequently to JDK17, demonstrating adeptness in managing complex transitions.A significant portion of my role involved comprehending and resolving issues at scale, working collaboratively with various infrastructure teams, including Kafka, Espresso, Pinot, and Venice.One of the highlights of my tenure was presenting at the QCon San Francisco 2023 conference, where I shared insights into the optimizations applied to the design and code of the Venice system, achieving an impressive 1 million operations per second per node.My commitment to continuous improvement extended beyond LinkedIn, as I actively contributed to open-source projects, including the OpenJDK, and made performance related contributions to libraries such as Avro and Log4J.To scale operations efficiently, I led multiple projects, including the development of a machine learning-based Java Garbage Collection tuning algorithm. This solution not only improved GC performance for internal applications but also automated the end-to-end process of validating results and deploying updated settings seamlessly.

• Implemented new 10x times faster build process based on Gradle, developed multiple Gradle and Jenkins plugins• Implemented cloud based Jenkins infrastructure integrated with all internal systems based on configuration as a code approach• Developed internal language agnostic boilerplate project generator to reduce project’s time-to-production to 5 minutes. It generates Git repository, example source code, build files, Jenkins pipelines, Dockerfile, Nomad configuration (deployment to cloud), has multiple templates (Java, Node, Python, Go) and available frameworks / APIs (SpringBoot, Prometheus scrape targets, Redis and Memcached integration, JPAs support)• Implemented Java artifacts knowledgebase with search and release feedback loop similar to Netflix’s Astrid and Niagara. It allows to track new releases of internal projects and libraries and automatically rebuild applications with new dependencies, providing feedback to developers• Automated internal on-boarding process by creating Ansible playbooks and documentations. It now takes 45 minutes instead of 1 day • Developing geographically distributed highly available CDN system for static content to maximize deployment speed and decouple back end and front end release processes• Developing tools for internal cloud, implementing persistent object storage for cloud applications using Ceph S3 interface• Hosted multiple internal training on Gradle, Jenkins and internal cloud solutions• Contributing to open source• Chaos Engineering, developing internal chaos experiments
