📖 Summary

Software Engineer @ LinkedIn Sunnyvale, CaliforniaSoftware Engineer 3 @ Adobe From October 2018 to March 2019 (6 months) San JoseSoftware Engineer II @ Cisco From June 2017 to September 2018 (1 year 4 months) San Jose, CaliforniaSoftware Development Intern @ Amazon Web Services Trusted Advisor Rule : W​rote a Trusted Advisor Rule to warn customers of Problematic Configuration Resource Record sets for DNS Based Health Checks. Wrote Java Code that loops through millions of health checks to search for a faulty configuration taking into consideration the performance and storage requirements. The code searches for problematic configurations such as CNAME records with either source name or target name matching the FQDN of the health check. In addition to this, the code searches for the wildcard record sets, alias record sets and a complex tree configuration containing weighted, latency or failover sets having health check with a different name associated with them but same health check id as the health check under consideration.The rule warns customers about these faulty configurations along with the details of the Problem. From July 2014 to September 2014 (3 months) Greater Seattle AreaSoftware Engineer II @ Cisco ->Implemented parallel field programmable devices upgrade for Delta AC power supply modules and brought down the upgrade time from 240 minutes to 45 minutes improving the performance by 6 times. Restructured the serial code and incorporated parallel upgrade across various power supply modules resulting in a performance improvement of 80% for QNX operating system based platforms. The project impacts all the current and upcoming Cisco ASR9K Platform Routers.->Worked with the Core Software Group under Platform Infrastructure ASR9K Team on low level device drivers for ASICs/FPGAs. Working on next generation routing technology and programming line cards with 32 and 64-bit operating system alongside debugging and fixing software level bugs for various platform components. Automated the power module FPD upgrade code using python and used Cross Test Framework and Fault Injection Mechanism to increase the code coverage for the power monitor component from 30% to 80%.-> Involved in bring-up process of Laserbeak line card and committed new IPU FPDs in addition to writing Consumer Model PIDs for new production line cards. Worked on system level bugs and resolved various intermittent process level issues. Performed Integration Testing of USB detection on 32 and 64-bit cards. From September 2015 to June 2017 (1 year 10 months) San Jose, CaliforniaResearch Intern @ Indian Space Research Organisation ->Designed a Microwave Hairpin Resonator for "Chandrayaan-2" lander and improved its frequency response substantially to gain an operating frequency of 3.972 GHz. ->Wrote extensive MATLAB Code for designing a 4th order loop filter for the receiver section of Chandrayaan-2 lander.Improved Noise Performance of the 4th order loop filter considerably by 5%. ->Designed a digital Phase lock loop using C. Worked on Synthetic Aperture Radar on board lander to achieve velocity accuracy of 0.4 m/s and a height estimation with 10 cm resolution. From January 2013 to June 2013 (6 months) Ahmedabad Area, IndiaDSP Intern @ Indian Space Research Organisation ->Worked on Virtex-4 Field Programmable Gate Array & OBC Micro controller based on-board signal processor which was used for storage and image processing of 1k x 1k monochromatic images in addition to 2-D filtering, 3-D DEM generation and 3-D Hazard Map Generation.->Analyzed the crater feature detection algorithm which involves processing of the initial Synthetic Aperture Radar(SAR) images of the moon surface into an unsupervised segmentation image which is followed by a geometric check and elliptic characterization.->Analyzed the working of the hazard map algorithm which implemented the process of assigning a hazard score which is a slope and roughness score to each pixel of the image which measures in both absolute and relative terms how risky it is for landing. From September 2012 to December 2012 (4 months) Ahmedabad Area, IndiaTeaching Assistant @ University of California, San Diego Worked as a Teaching Assistant under Department of Mathematics at UCSD ,teaching vector calculus to more than 150 students.Course included change of variable in multiple integrals, jacobian, Line integrals, green’s theorem,vector fields, gradient fields, divergence, curl,spherical/cylindrical coordinates,taylor series in several variables, surface integrals, stoke’s theorem,gauss’ theorem and conservative fields. From January 2014 to March 2014 (3 months) Greater San Diego AreaTeaching Assistant @ University of California, San Diego Taught Linear Algebra & Matlab programming to 200 undergraduate students which included matrix algebra, gaussian elimination, determinants,linear and affine subspaces, bases of euclidean spaces,eigenvalues and eigen vectors, quadratic forms, orthogonal matrices, diagonalization of symmetric matrices,computing symbolic and graphical solutions using Matlab. From September 2013 to December 2013 (4 months) Greater San Diego Area
