• Embedded Systems - Implemented performance analysis using Raspberry Pi 3 performance unit for measuring instruction count, cycle count, cache access times for various C based workloads. Developed an Energy Efficient EDF scheduling algorithm for a 8 sensor based workload. As a part of the final project, built a home automation system that works with the Apple Homekit Ecosystem supporting off the shelf uncertified hardware by using reverse engineering protocols.

• Database Systems - Built a simplified XPath, XQuery engine for XML data from scrach using ANTL4 for frontend and Java for backend. Advanced features include detecting joins and optimizing them into hash join algorithm.

• Distributed Systems - Implemented voting part of RAFT consensus algorithm, A distributed data Store service and performed various datacenter analysis using AWS regions.

• Compiler Design - Implemented Liveness analysis and May-Point-to analysis using LLVM infrastructure.

• Software Engineering - Refactored an Andorid based game using the principles of SRP, LSP, Contracts, Dependency Inversion, Strategy, Observer patterns.

• Learning Algorithms - Implemented prototype selection algorithm for 1NN, Coordinate descent algorithm, and scaling probablities using Platt scaling and Isotonic Regression

Industry

SDE Intern, Mulesoft (A Salesforce Company)

Part of the AnypointMQ team that maintains the message queue feature of Mulesoft’s AnyPoint platform. Anypoint Message Queue is a Distributed Message Queue datastructure that comes with a drag and drop connector as a part of Mulesoft’s Anypoint Studio. I was involved with developing the full stack feature of delay queues and am currently working on message groups feature. I also worked on our internal tools and testing frameworks in the spare time to make the ops work easier.

Technologies Used: SpringBoot, React, Node.js, Jenkins, Docker.

SDE Intern, Postman

• ratelimiter - A rate limiting hook for sails.js that has configurable limits using redis as a datastore.
• exception-reporter - A hook for sails.js that reports uncaught exceptions thrown by a node process in production to slack with useful information.
• jsdoc-postman- A CLI tool that automatically generates a postman-collection from jsdoc comments.

Technologies Used: Node.js, Redis

Intern, Microsoft

• ContosoCabs - A Xamarin based application that utilizes Cortana Insights to book the best cab for the user

Technologies Used: C#, Xamarin, Node.js, PowerBI

Personal

• nodeforces - A CLI tool to parse codeforces i/o and run tests automatically
• cryptle - An IOT based smartwatch app that has real time alert service and smart lock capabilites.
• foodonz - An Android app that helps ordering food in and around Vellore (wip).
