Architected, developed, and deployed a telemetry solution that streams data from AWS network devices to SDN controllers and monitoring services. This publisher-subscriber-based system replaced and deprecated the decade-old SNMP polling protocol in AWS data centers, resulting in over $5 million in savings over five years. Technologies used: C++, Python, Java.* Engineered a scalable telemetry protocol with streaming capabilities using a publisher-subscriber design pattern, enhancing telemetry collection frequency from 60 seconds to 10 seconds for improved real-time data analysis.* Built core components to ensure reliable telemetry delivery under any network conditions using the gRPC streaming protocol. Implemented features such as periodic and event streaming, rate limiting, data prioritization, authentication, authorization, and encryption in transit.* Executed the deployment of the telemetry solution across all AWS data centers, encompassing 1.6 million network devices, using multi-phased strategies to ensure fleet safety.* Designed and implemented a solution for exporting ad hoc telemetry from network devices, replacing costly SSH-based telemetry collection. This innovation reduced collection frequency from 5 minutes to 30 seconds, resulting in significant cost savings and increased efficiency.* Developed a solution for efficient alarm delivery from network devices, transitioning from regex-based syslog alarming to push-based events with structured messages, facilitating easy consumption and data enrichment in downstream services.* Crafted team roadmaps, coordinated project deliveries, and led a team of six software developers to achieve successful project outcomes. Provided mentorship to junior engineers and interns within the team.

Developed a solution that provides Configuration sharing mechanism among the users of the application. Technologies: Java and C#• Created a Configuration manager, a platform that enables users to share their configurations with others. • Built a file format agnostic solution to support any type of configurations. This increases the re-usability and improves the availability of the configurations by storing them in Cloud.

i. Equipment data unifying Data Hub ArchitectureCreated a solution that collects log files from equipments at Semi conductor fab and analyze the log data to provide the health status of equipment using predefined patterns.• Created “Log Manager” that effectively collects data from equipments and stores at central database repository (Hadoop) on creation of log file at Equipment end.• Log Manager manages the file system based on Equipment/ Administrator folder settings.• Provided efficient search results by storing metadata of log files such as Creation date, Generated equipment. • Provides features such as compression, deletion and archiving of log files after prescribed time interval.ii. Assessment Solution for Smart EducationDeveloped Assessment solution for Samsung Smart Education application. This module provides solution to assess students using various grading mechanisms. • Developed a platform where instructor can input grading schema of his interest or can select from predefined grading schema.• Evaluating students’ performance based on scores using grading mechanism provided by instructor.• Generates student’s comment based on his performance and rules defined by instructor. Instructor can also provide specific comment on particular student(s).• Created Web service methods and exposed REST APIs to consume at client application.

Developed several windows phone 8 applications which are internal apps to Microsoft employees & also retail applications for Windows Phone 7 & 8.• Worked on SQLite database along with Gzip compression, LINQ queries for fast retrieval of data, Notifications, Template based retail applications, Automating build generation, Collecting Telemetry data etc• Developed user interface for many pages which includes Dashboards, Advance search, Custom controls using Expression Blend etc.• Developed web services methods that are used by mobile applications. Used Windows Azure to host web services• Written stored procedures to store and retrieve data from large partner database of Microsoft using Dynamic SQL
