Vaibhav Pathak — Senior Backend Engineer
Hey I'm Vaibhav, a Senior Backend Engineer with 5+ years building
distributed systems, microservices, and cloud-native platforms. These
days I'm deep in AI engineering — RAG pipelines, LLM integration,
semantic search, and generative AI in production.
Currently building
Ant Mascot.
Oh, and did I mention? I use Arch, btw. My setup is so minimal, it makes
Marie Kondo look like a hoarder. Neovim is my text editor of choice, because
why use a mouse when you can do finger gymnastics? And yes, I rock i3 – because
tiling window managers are the closest thing to telekinesis in the digital
world.
Let's connect and geek out together!
