Food online ordering is a real-time business and has its own challenges ranging from ordering to delivery experience.

- Scaling the system for 10x orders a week.
- Breaking Zomato monolith into micro-services.
- Establishing processes required to scale the engineering for long-term.

Engineering Team Lead

Lead a team of 4 to automate content systems. The aim was to remove every manual step starting from the collection of data from the restaurants to make it live.

- Introduced crowdsourcing app for collection of content with the help of users.
- Built the pipeline to process, derive and update the content.
- Built a version controlling system for the content.

Engineering Project Lead

At the point Zomato was in about 16 countries including US in far west and New Zealand in east after acquisitions.

- Setting up Point of Presence(PoP) to eliminate single point of failure(SPOF) and reducing latency for users in USA and New Zealand.
- Added Cassandra DB to the main stack for storage.
- Experimented with distributed storage like Gluster FS, Torrent, S3, custom storage etc.

DevOps

Serving restaurant’s ads to its users is Zomato’s main business until now. I led a team of 3 to build Zomato’s in-house enterprise solution for its ads business. The system was built for scale and long term.

- Ads Service to serve right ads to right users.
- Business Management service included on-boarding restaurant businesses, managing their billing and analytics like RoI, page views etc.
- Sales Management for internal sales team and management to track sales targets and revenue at the individual and gross levels.

Software Engineer

Zomato’s core competency in the food-tech space has always been quality and quantity content on its platform. During this period I created necessary tools and dashboard that sped up operations and team efficiency along with user facing features like user feed, photo viewer etc. At the time of joining, Zomato was in 2 countries and by the end of an year it expanded into 10 countries

I started working on web technologies way back in my college time. I am well versed with other programming languages like Python and Go as well. At the moment PHP is the my core language of development at Zomato, where I work. I also am aware of the build tools for PHP like composer which helps in taking advantage of the community built modules to help build faster.

I have used Javascript for prototyping many of my projects and being a full stack developer this is also one of my tool for web development. Zomato, where I work, is a very product focus company serving 100 million users a month. This is where I learned to take advantage of Javascript in order to create wonderful experience for the people.

I have built and lead projects ranging from prototyping to large scale application in production. My last project included building data pipeline for automating content generation for my company at Zomato. It included web application and background data processing of GBs of data every week.

I first used Node.js back in about 2013. It was a whole new paradigm of building applications at backend. With Node.js came projects like socket.io to complement the nature of Node.js. Without saying node.js and express.js go together with respect to web development. I believe in minimal framework and building custom solutions that fits my use case. I have worked on real-time applications at Zomato along the with sockets for real-time status updates and that too on large scale, 30k connected devices at a time.

I have been using Git since I first came to know about it about 7 years ago for version controlling. I have good expertise in how to create processes for team to work together and to be able to focus on the idea they want to build. Git is the central piece for that for me. The other things included in the process is CI/CD.

Online Ordering Scale Up

A simple to-do app which works in context of the webpage and lets you create list right there.

Quarks App

Built the generic framework to version control data to support content updates from unverified parties in order prevent pollution. This lets operations team to easily manage content on Zomato's platform and revert the changes if required.

Version Controlling of Data

A system to scale Redis to support multi-master and syncing across data centers which are geographically distributed.

Distributed Redis

Created feed for users at Zomato where they can see review, photos and checking of the people they are following on Zomato. This is primary source of discovery of great places to eat. As a first version I built this on Redis but as Zomato grew from one country to another handling 10x more traffic, migrated to Cassandra.
