Big Data Platform---------------------Tech lead in the Bigdata platform team, handling ~25PB of data with ~1000 machinesScaled up Apache Kafka to handle real time ingestion of ~1million events per second, with event sizes ranging from 1KB-4KB. Contributed to Apache KafkaWorked on a validation framework to validate the strongly typed event according to the schema. Worked on a tool to manage the universe of versioned schemas.Built a Data Lake to consolidate disparage sources of data and bring them all to the platform for a single system imageExperimented with swap space and found performance gains of ~15% by tuning node manager published memoryHandled cluster stability and multiple deep technical issues with the cluster.D42 Object Storage-----------------------Tech lead in the storage platform team, offering cloud-based object storage services API compatible with AWS S3 used as part of multiple business-critical workflows. Built on Ceph, RadosBrought up an archival cluster, with erasure coding to drastically reduce replication space requirements, to store company critical compliance dataUser Engagement and Growth------------------------------------Focused on products and tools to engage and grow user base. Notifications, Product reviews, Product comparisons.Worked on a migration from http-based micro services to Apache storm

Architect and implement the web application which interfaces to the Coverity static analysis toolWorked on deploying Coverity web application on the cloud (https://code-spotter.com/). Up until then, Coverity Web app needed to be installed in-house for every client.Technologies used: Webservices, Many spring components, postgres and most other popular open source web application libraries, e.g., Jackson, Jaxb, ActiveMQ, Quartz schedulers, etc

Collaborated with other developers and the senior management team to evaluate new technologies, assess development frameworksAs technical lead, aligned processes with industry best practices around software development, performance, scalability, maintenance, and securityPioneered Test driven development with real time feedback by polling for changes to code and running affected test cases.

Courses TA'ed include -- Introduction to Algorithms (3 times)-- Theory of Computation-- Introduction to C programming-- Data structures and algorithms in JavaResponsibities included homework/exam grading, occasional teaching, holding recitation classes, holding office hours, maintaining course websites etc

I was responsible for updating the solution manual for the third edition of the well known "CLRS book" (Introduction To Algorithms). Not only did I have to provide correct and concise solutions to the new problems in third edition, I also had to be extremely careful about the language, making sure that nno ambiguities occur and the solution is readable by students with varying levels of mathematical proficiency.

Managed a team of 8 in implementing a module for FieldForce Optimization Suite.-- Project won the national outsourcing award-- RISE Award for innovation at workplace-- Third place in Infosys Excellence award in the category “Code champion-Programming Skills”

Fieldforce Optimization suite: A 3-tier J2EE web application using struts and oracle. Developed an optimization engine, which draws upon operation research (Notably the hill climber algorithm) to solve the problem of matching workforce to jobs.White PaperMulti threaded database access using JDBCNotableThird place in Infosys Excellence award in the category “Code champion-Programming Skills”

I developed a "Radar Target Simulator" for the Ministry of Defense. Designed with a visual basic front end controlling a DSP processor (ADSP 21061) programmed using a C cross compiler, It was a tool to test the behavior of new radars on moving targets.
