Learning in public · Building a free study vault

Hi, I'm Deven Kalathiya.

Cloud & DevOps Engineer exploring AI, RAG & LLM-ops. I document everything I learn — the notes, pipelines, and architectures — so you can use them to crack the same certs and build the same systems.

Products I help build & operate

What I love about working here

Real scale, real challenges

Crawling, deduplicating and serving millions of feeds is a meaningful systems problem — perfect ground to actually understand caching, queues, and rate limits.

🤝
Supportive, autonomous team

The kind of place where curiosity is encouraged. R&D time, room to experiment with new tools, and freedom to bring AWS AI services into the stack.

📈
Visible impact

A pipeline I optimize today serves real users tomorrow. The 30% efficiency improvement on processing pipelines? Felt across millions of feed updates.
