Hi, my name is

Vaibhaw.

I bootstrap ideas into products.

From Fortune 500s to healthcare startups to indie side projects — I've built data pipelines processing millions of records, real-time IoT dashboards, and open-source dev tools. I use AI to ship faster without losing control. IIT Bombay alum. Rust, Python, TypeScript.

03. About Me

I'm a bootstrapper at heart — give me a problem and I'll ship a solution end-to-end. I use AI to move fast — coding assistants, LLM APIs, automations — but I always understand what's running and review every line before it ships. Speed without losing control.

My journey started at IIT Bombay, where I led tech teams, broke a Guinness World Record, and caught the building bug that never went away. Since then, I've worked with a diverse range of clients and industries — architecting data pipelines at a healthcare startup, building IoT dashboards for a Fortune 500, shipping enterprise web apps at consultancies, and bootstrapping my own open source tools. I'm equally comfortable in a boardroom with stakeholders and in a terminal at 2 AM.

Here are a few technologies I've been working with recently:

  • Python / PySpark
  • Rust
  • TypeScript
  • LLMs / AI APIs
  • Docker / K8s
  • Apache Hudi / Kafka
  • AWS (EMR, Glue, S3)
  • Automation & Integrations
