Developer Division → Visual Studio for Mac

Developing the best developer tools and services for hundreds of thousands of customers

- Proposed, led and implemented Visual Studio for Mac Performance effort to make it the best IDE on macOS. Built the foundation of  VSMac performance effort to prevent reinventing the wheel
- Implemented VSMac Performance SDK, infrastructure (IaaC), processes (best practices), tools (analyzers and visualizers) and standardized metrics to act as “north-star” to guide the product towards performance improvements.
- Built end-to-end internal data processing pipeline to capture performance data from VSMac running in internal labs, find trends over time and correlate it with customer telemetry. Use internal processed data to determine the quality of the release for the upcoming releases.
- Built developer tools enhancements like instrumentations, profiling, AA and AB comparer etc  to aid in rapid prototyping of performance fixes.
- Maintain and improve Visual 

Visual studio has a feature called record and play which can record user activities and play it back. This feature depends highly on accessibility capabilities of the application.

Written a tool which checks the website and creates reports with information on to which extent the website or application can be recorded. Useful for clients who want to check their application compatibility.

Xamarin Studio: Primary responsibility - Integration, Release and Quality

* Coordinate all major and minor releases including Servicing Releases for Xamarin Studio
* Coordination includes, selecting builds, assessing the quality, sending all the emails for sign-offs and getting the release notes for publishing.
* Mentor and coordinate with our vendors to make an informed decision to publish the selected builds.

Installer for Tizen Mobile OS: Worked on the installer used for Tizen Mobile OS to be used by PC and IVI (In-Vehicle Infotainment) verticals of Tizen Group. Finished features which are needed for making the installer UEFI capable, enabled the installer to use both liveusb and raw OS images for installing.

Tizen Workflow Mock: Development of a tool to monitor and debug the problems faced in the infrastructure used for Tizen OS Development. This enhances the infrastructure monitoring capabilities over nagios which cannot detect problems caused by missing/faulty configuration of servers, authorization issues and timeout problems.

About Tizen: Tizen is an operating system for devices including smartphones, tablets, in-vehicle infotainment (IVI) devices, and smart TVs. The Tizen project resides within the Linux Foundation and is governed by a Technical Steering Group (TSG) composed of Intel and Samsung.

Development of an Application which can be used to create and edit Device Description XML which is based on an ISO Standard ISO 15745-3. The standard describes the way information about an Automation Device has to be stored in an XML file such that it can be used by machine.

Technologies Used: C#, .NET, XML
