• Was the founding engineer from Hyderabad site and assisted with growing the engineering teams. Worked as developer cum lead within the Maps team. Owned and contributed to bunch of services within the data platform - primary ones being conflation pipeline, training platform, workflow processor, notification system and data aggregator. Conflation pipeline involved merging Open Street Map data with different vendors in order to visualize and evaluate the correctness of the generated maps. Training platform was single-stop shop for training and evaluating map editors, this system hosted evaluations, training materials and certifications which were earned by the editors. Workflow processor works in tandem with state management service, together these two services take care of running any kind of complex workflows (required in data team) via exchanging messages. Notification system is used to connect different systems within the data platform and in turn automate lot of map development process. Data aggregator offers the capability to capture, aggregate and analyze map editing data which will help us gauge editor productivity, estimates on completion timelines, payments and numerous other use cases.

• Worked with disaster recovery team within Windows Server Group (IDC). Completely owned end to end design and development of virtual machine resynchronization feature from host server to Azure and vice-versa. Took ownership of feature scaling and performance both on host server and Azure. Performance challenges on host server were around minimizing the overall CPU impact, using suitable data structures to reduce the replication latency because of disk reads. Since there were many customer virtual machines replicating to Azure, main challenge on Azure was to design cost-effective service which can tackle and scale-up to handle as many number of resync requests coming from customer virtual machines. Additionally worked upon devising mechanism to counter DOS (denial of service) attacks, encryption and security aspects related to replicating virtual disks from host machines to cloud.

• Arcot authentication application is used by customer parties to authenticate users of their system. The application kicks in when the user hits customer home page and tries to authenticate himself; this entire process from logging-in to approving authentication is done by the authentication application. l worked on development of authentication application (Identity Provider / Federation), bug-fixes, addition of new authentication flows, user interface changes on customer demands. Made contributions to design and development of new version for the flow framework which could be modified directly by customer/admin as per their requirements (was supposed to be a self-service version). Wrote graph algorithms to validate these custom authentication flows which could be created.
