Drove the development of seamless cross-device experiences, partnering with OEMs to enhance Windows and Android user interfaces.• Orchestrated the rollout of enhanced authentication by re-engineering 9 microservices and multiple clients, successfully reaching millions of customers without downtime. • That effort resulted in seamless integration of all microservices to utilize one common platform for authentication. The optimization significantly reduced development cycles, resulting in cost savings for both ongoing and future development and reduced points of failure. • Led full-stack development and provided on-call support to ensure project success and operational continuity.

Spearheaded cloud-based microservices and REST API development, leading teams as Scrum Master and Tech Lead.• Transitioned microservices to utilize Azure Cosmos DB for enhanced user data handling, ensuring privacy and compliance for millions of global users.• Managed authentication processes and conducted complex privacy and security reviews, collaborating across teams for successful deployment and support.• Led the large team of developers as scrum master to redefine and reuse agile based methods.

Led cross-team initiatives critical to ink-related features for Windows and Office, supporting billions of users with diverse language models.• Led 2 cross geo external vendors (VueData and Lionbridge) to collect more than million ink and math samples collected based on different age, gender, and geographically diverse populations.• Developed data collection tools and coordinated global projects, driving innovation in input intelligence.

Contributed to the lifecycle of Microsoft Band, focusing on authentication, data sync, and web encryption.• Partnered with industry leaders for requirement gathering and integration, ensuring seamless production support.• Participated in design and development from inception till shipping of Microsoft Band-I and Band-II.• Led execution of serval components including user authentication, third party data sync and encryption while helping other team members in delivery, deployment, support and load balancing. • Worked with state-of-the-art technology using C#, Azure, Azure Storage, Azure service bus, Event hub, SQL Server, Restful API Model etc.• Collaborated with partners such as MyFitnessPal, RunKeeper, MapMyFitness etc. for requirement gathering, integration, development and production support.

Developed multiple modules for robotics data center to create a highly available and reliable ecosystem. Implemented Azure ACS based security for user authentication.

Enhanced user experiences through effective cross-geographical collaboration, achieving milestones with significant impact. Managed bug triaging and resolved issues to advance product development.

• Led teams to ensure robust delivery of features, managing bug prioritization and spearheading zero unresolved bug initiatives. • Worked with peer test leads to prioritize bug appropriately; help team to get P0 fixes in ASAP to unblock dependent teams and ensure timely execution of end-to-end BVTs.• Developed features of the project using C#.Net and SQL Server 2008 and participated in code reviews. • Managed and monitored bug regression statistics; this included getting metrics for (and hence identifying) the number of regressions that took place during the product life cycle• Drove team-wide efforts to reach ZRB (zero resolved bugs) and ensured that vendors were properly regressing and resolving bugs assigned to them.

• Developed features to support azure platform using C#. • Maintained the integrity of azure components and wrote integration tools.• Worked on automation, deployment and integration of Windows azure component. • Developed applications for cloud computing and performance measurement using C#.• Wrote unit test (both functional and E2E) for owned features to enhance code coverage and worked with test owners to ensure adequate test coverage.

• Solo developer of IPICS windows mobile feature that includes usage of SIP stack (Open source PJSIP stack).• Worked on the open source development techniques for windows mobile, embedded platform. I also managed the multithreaded and multisession real time environment.• Helped my team to design, implement and ship other major features of the project. • Active participant of design reviews, requirement specification and test plan review meetings.

• Worked in .Net(C#, VC++), SQL Server 2005 and its enterprise libraries for development of low level device communication.• Used windows and Linux based environment for various module of the system, implemented and managed the multithreaded and multisession real time environment.• Wrote unit tests, performed remote debugging and monitored application performance.• Drove technical meetings with client project manager involving discussions over complex and performance specific issues.• Manage (create/update) functional specification documents for ongoing development.• Coordinate test case preparation, unit testing and integration testing.

• Designed and implemented gateway between SIP and legacy world. Also participated in web service management. • Used design patterns in design documents and functional specification of the project. • Suggested and designed architectural changes for software development and VOIP protocol level developments.• Performed unit testing with remote debugging concepts. Measured the performance of application.• Participant of design review (PDR) and critical design reviews (CDR) meetings.• Architect the solution framework design using design pattern and object oriented analysis and design.• Implemented this project by taking references from IETF standards RFC(s) (3261, 3428, and 3863) and other various supporting standards.• For testing I used NUNIT, .Net Profiler for memory management and performance measurement

Oversaw the entire product development lifecycle, established and fleshed out the application's architecture and scope. Directed the technical team to create error-free and resilient programs.

Created the VOIP features for phone communication using established RTP and RTCP Stacks to ensure smooth interaction. Implemented TCP/IP protocols, curated installer and deployment manuals for remote support and developed the communication layer by integrating C++ TAPI into C#.
