Arpit Bhayani

Hey, I am Arpit

curious, tinkerer, and explorer

I am a software engineer and an engineering leader passionate about Databases and System Architecture. Right now, I am a Staff Engineer for GCP Memorystore, handling both dataplane and control plane. On the side, I created an open-source reactive cache - DiceDB.

In 2024, I took a leap of faith and co-founded Profile.fyi, which was later acquired by Mercor. I have also been a Staff Engineer at Google, leading the Ads Forecasting, and was the lead for the Dataproc India team, where we built a managed big data ecosystem for GCP customers. Earlier in my journey, I was part of Amazon's Fast Data Team, where I worked on cold tiering of hot data and developed a seamless query interface across all storage 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 12+ 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.
