- Crafted a novel genetic algorithm based SAT solver in Java to solve an NP-hard problem of allocating ads to videos with multiple constraints in real-time- Modeled the ad allocation problem mathematically allowing the use of constraint solvers to find optimal solutions- Built a stochastic greedy algorithm to allocate video ads resulting in a 8x speedup with near optimal performance- Added a new ad playlist serializer ingested by video players allowing dynamic ad placement , tracking, and control

Redmond, Washington, Us

- Designed and implemented an optimal sharding strategy to partition arbitrary streamed input events- Reduced number of sharded output files heavily by efficiently caching file handles while minimizing memory usage- Increased write throughput to Blob Storage by 13% by migrating all IO operations to asynchronous tasks- Introduced feature flags, enhanced validation, and added telemetry improving service incident mitigation

Mountain View, Ca, Us

- Drafted a design document for a private library hosting service running on App Engine and Container Engine with a multi-tier architecture saving 25% in operational costs, https://git.io/v7lDV- Implemented the service with 99.95% uptime and tooling to manage its deployment to Google Clou dPlatform (GCP)- Improved service CPU usage by 2.5x with asynchronous file backups triggered by whitelisted requests- Added OAuth2, GCP compatible storage / database layer, and server orchestration for load balancing on top of an existing library leveraged for hosting functionality

Ottawa, On, Ca

- Built a scalable, dynamic, and robust mobile continuous integration system leveraging shared storage for optimal build speed- Automated and optimized virtual machine provisioning speed by 120% and sped up deployment by a factor of 7.6x- Improved build times by 350% by building caching infrastructure leveraging a Shared Area Network and Redis- Prevented concurrency problems leading to data corruption by designing efficient non-blocking alternatives- Updated logging services in internal infrastructure to easily identify performance bottlenecks and collect statistics

Markham, On, Ca

- Designed management platforms with React adhering to the Flux architecture- Configured development servers on Heroku and staging servers on AWS- Abstracted database logic through Ruby’s ActiveRecord ORM- Built RESTful Rails APIs with a JSON Web Token based authentication system

Mississauga, Ontario, Ca

- created interactive data visualizations for a reporting platform- led development with ETL tools (Informatica) in creating file transformation workflows- assisted in organizing an internal hackathon, designed and implemented a responsive website from scratch- wrote automation scripts and used JIRA to debug/monitor issues

- optimized machine start-up times by removing unneeded software - cleaned registry values and BIOS to enhance system performance- trained clients to be more adept with computers

- ensuring employees are completing given tasks in a timely manner- using social media and other marketing techniques to boost product sales- maintaining tables of other departments and their IT needs- training company employees in different divisions in the technology field- developing strategies and plans with other vice presidents for the long term goal of the company
