Arpit Bhayani

Hey, I am Arpit

tinkerer, educator, and entrepreneur

I am a software engineer and an engineering leader passionate about System Architecture, Databases Internals, Language Internals, and Advanced Algorithms. I am the creator and maintainer of DiceDB - a database hyper-optimized to build real-time applications with its SQL-based reactivity.

In 2024, I took the leap of faith and co-founded Profile.fyi, where I am operating as the CTO taking care of all things tech. Before this, I was a Staff Engineer at Google leading the Dataproc India team in providing a managed big data ecosystem to GCP customers. I was also part of Amazon's Fast Data Team and took care of cold tiering of hot data and providing a seamless query interface across all tiers.

I held engineering leadership positions (both IC and management) at Unacademy, where I built, grew, and led Search, Site Reliability Engineering (SRE) teams, and Data Engineering teams. I hold a total of 10+ years of experience in scaling backend services, taking products and teams from 0 to 1, and beyond.

I keep diving deep into engineering details and share my learnings by across my socials and videos on YouTube.
