• March 2014 - June 2014
• Leading the development effort of a new mobile game. Responsibilities include finalizing the tech stack for the game, develop the backend supporting systems while the game takes shape, and also create prototypes of early ideas about the game. Using Unity and C# for the prototyping currently.
• November 2013 - February 2014
• Rejoined the core Mafia Wars game team. Helped in server and service cost reduction initiatives which helped reduce cost of running the game by $5000 per day.
• Handled the datacenter migration of the databases and consumers from the game team side, with the support of DBA.
• Investigated systems like Robbing (a PvP system) and Player Updates (news feed for PvP and other activity in which the player is involved directly or indirectly) and came up with redesigned architectures for them to improve performance - which was something the players had been complaining about for a long time.
• May 2013 - October 2013
• Was part of a small team of five people (I was the only developer) working on a new mobile game idea. Explored various options available for 2D mobile game development at the time and settled on Cocos2d-x (C++). Over the next few months, worked with the rest of the team in coming up with a prototype for a fighting game, playtesting it with folks from other teams, and polishing it based on feedback. The prototype was well liked, but we were not given the go ahead to build the complete game by the higher management team in the end.

• January 2013 - April 2013
• Led the performance improvement and server cost reduction efforts for Mafia Wars. Used the detailed profiling data for the PHP game code from Zperfmon to determine the places where an improvement would have maximum impact. Made multiple fixes to the game code, and took steps like using hidef for storing some of the game config data to improve CPU usage on the web nodes by about 10%.
• Consolidated the numerous memcached pools based on the traffic being received to reduce the total memcached servers being used by around 40%.
• Created a matchmaking and bucketing system for one of the PvP systems in the game using Go.
• November 2012 - December 2012
• Supported the CTO of the game in the datacenter migration for Mafia Wars servers by taking ownership of multiple components like Memcached data and server migration, various consumers and queues, etc.
• September 2012 - November 2012
• Led the frontend development of Arena, which was a synchronous PvP fighting system - using websockets to communicate with the backend Go servers, and using HTML5 to perform all the fight related animations.
• April 2012 - August 2012
• Continued working on features in Mafia Wars, passing along the knowledge of various systems to the freshers who joined in this period, and other team members.

• The time with the team culminated with the launch of a new City(Old Blood) in the game which took the team nearly 4 months to deliver from start to finish, and was the biggest Bold Beat done by Zynga's Studio I until that point.

• October 2010 - December 2010
• Helped with the transition of the YDN (Yahoo Developer Network) project to Bangalore. Took over ownership of a new component which involved writing web services which act as the single source of truth for information about all apis and services exposed on YDN to external developers.
• April 2010 - September 2010
• Worked on "Web Service Libraries", which was a set of C++ and PHP libraries used internally in Yahoo! by various teams to expose their web services, and to call web services exposed by other teams.
• The libraries were written as Apache modules and PHP extensions in C++. Solving issues raised by the customers involved using GDB with Apache extensively.
• I took over the development/maintenance of the libraries from the sole developer working on them in a week (codebase of over 100,000 lines) . The work was recognized by my manager with a spot award, since the 80+ customers of the libraries didn't at any point feel that the libraries were unsupported.
