• ● Deployed a complete self-hosted solution for VPN to connect to internal applications and sensitive applications for the entire ORG, which is highly scalable, currently handles 150+ concurrent connections, and also supports split-tunneling, this was done by deploying a PRITUNL VPN Cluster which is completely self-managed.
• ● Briefly led the DevOps team for a duration of a few months, During this period I would lead the Daily standups, help resolve issues faced by my colleagues, and maintain a 2 people team for On-call which used to be a rotational basis for helping developers for resolving issues, monitoring production, etc. And the rest of the team would work on building other features and other tasks on the Infra to provide more features to developers or improve and secure the Infra based on the inputs that I gathered during weekly calls from senior EM's and architects.
