I’m Rahul Xavier Singh. I want to bring the best knowledge and the best professionals together to serve the world’s businesses.

Here are my main work projects.

Anant - Data Platform Services for Cassandra, Spark, Kafka

Most technology leaders have a hard time retaining the experts to help them build and manage global data platforms because of the high costs of specialized talent so we created a Playbook for their teams and a Service Catalog delivered by a network of trained specialists on our framework that are available on a full, part, or on a project by project basis.

Cassandra.Link - The World’s Best Knowledge Base on Apache Cassandra

Most data practitioners are overwhelmed by the amount of knowledge they need to be proficient with Cassandra so we curated an authoritative knowledge base on Cassandra with hand picked links, jobs, and experts to help them throughout their journey to mastery.

The Platform Playbook for Modern Enterprises

Having seen the same issues at several clients that are trying to implement “real-time” technologies, I am writing a playbook that describes principles to design, build, and manage global data & analytics platforms.


I’ve been using Langchain/LLMs with OpenAI’s GPT API since late November 2022 on a few ventures and research projects. Building on my experience building global scale data platforms using technologies like Cassandra/Spark/Kafka, Scylla, Pinot, Elastic/Solr with an emphasis on DevOps/DataOps/MlOps Automation, I’ve added langchain to my toolkit as part of the DataOps / processing and for API / retrieval. With my previous experience in building enterprise search pipelines, I’ve been using vector stores and elastic search to create APIs consumed by other APIs, traditional front end frameworks, and NoCode automation and UI platforms. I’m here to help anyone who wants to create experts, assistants, and platforms for businesses that want to make their employee’s lives easier.
