Cloud Migration Platform, pronounced, is an open-source project for migrating clients' infrastructure. The migration can be conducted from one data center to another, from a data center to a cloud, from a cloud to a data center, and from one cloud to another. This project is fully open-source and actively maintained.
Xforecast is an open-source tool for forecasting real-time data built for system and application metrics on a time-series database. It can fit right into customers' current observability infrastructure if they are using Grafana, Prometheus, or InfluxDB stack. I founded this project, and now I am actively maintaining it with some of my close friends in the open-source community.

Opsbrew is a log pipeline management application built on top of Kubernetes. I started this project as an MVP and got a chance to work on this as the team lead.

I managed a team of 10 front-end, back-end, and QA engineers. I defined the product roadmap and sprint tasks for all of them. Also, I led the team to deliver the product and win a hackathon by Microsoft for the same in six months. Read more here:
