Hey, I am Arpit

curious, tinkerer, and explorer

I am a software engineer and an engineering leader passionate about Databases, System Architecture, and Advanced Algorithms. I am also the creator and maintainer of DiceDB - an open source in-memory database.

In 2024, I took a leap of faith and co-founded Profile.fyi, which was later acquired by Mercor. Today, I am a Staff Engineer at Google, leading the Ads Forecasting. Before this, I had led the Dataproc India team, where we built a managed big data ecosystem for GCP customers, enabling them to handle data at scale seamlessly. 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 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.

Let me help you

You need to build your next big service and need help with picking the right tech stack? Do you want to be sure that the system you are building is future proof system? I can help. I advise startups and here are some things I can help you with.



System Architecture and Design

Designing and building your next big backend service can be daunting, but I can help ensure it's scalable, high-performing, cost-efficient, and future-proof.

Picking the right stack

The backend stack - databases, languages, and big data tools - is overwhelming and I can help you make sound and informed decisions tailored to your constraints.

Database and schema modeling

Databases are the most brittle component of your architecture and I can help you model the database schema to ensure it is lean and performant.

Performance Improvements

Inefficient 3rd parties, DB calls, and naive threads can degrade performance. I can help you identify such issues and make your implementation and infra efficient.

AWS Cost Optimization

I can help you find inefficiencies in your AWS infra and suggest right-sizing and efficient designs to eradicate over-engineered choices and lower your cloud expenses.



So, if you are a startup and you think I can help you with something, book a call.
