About Me

I am a software developer at Google and have been lucky to have interned at tech giants like Amazon and Nvidia.

I have expertise in training for interviews at software tech companies, with a focus on
Data Structures and Algorithms, System Design and am skilled at Open Source Software and programming languages like Python, Java, C++, Version control systems
and databases.

I have been a core contributor (C++) at MariaDB foundation (2018-2019) and have contributed to projects under Mozilla (Outreachy intern 2016), Linux Foundation (OPNFV intern 2017 - Python) and OWASP code sprint 2017 (Python) and am an active contributor at QuantStack (Mamba project), Google BigQuery (Scientific Computing) and OpenMined - PSI library (Homomorphic encryption protocol).

1. Mozilla Firefox (Outreachy Open Source Project) (May - Aug 2016)
   Participated in the May-August 2016 round of Outreachy
   Made the following contributions to Mozilla during the course of the
   internship:
   a. Designed and developed a content-process management tool that can
   track real time memory usage across each process in the Firefox browser
   b. The project helped scale up and tune the number of content processes
   that Firefox starts or uses, keeping memory measurement in mind
   The tool is accessible by hitting about:performance in the Firefox
   browser (got shipped in Firefox 51 onwards) and it reports the RSS and
   USS memory performance and is platform-independent (works well on
   operating systems like Windows, Linux and Mac OS X)

   a. (Bug 1061521 - Throw Component.exceptions instead of strings in
   about:memory)

   (Patch link:
   • https://bug1061521.bmoattachments.org/attachment.cgi?id=8738227).
   b. Prior to this patch, test cases for testing loading of reports from
   aboutmemory.js using test_aboutmemory3.xul were working only partially (3
   passed and 1 failed). After this patch, all test cases pass (7 out of 7,
   with 0 failures).

   download directory for about:memory)

2. OWASP Code-Sprint (Jun - Jul 2017: (AppSensor Project)
   Worked with Python and built a web server log analysis tool suite based
   on ML (machine learning) in Python using Numpy, SciPy, Scikit-Learn and
   K-Modes libraries. This accepts as input web server logs (apache) and
   provides as output a determination of requests that are considered
   "attacks". Used different algorithms like Clustering, Decision Tree,
   Naive Bayes, etc. after parsing through the log data, converting it to
   python dictionaries from Json objects and pre-processing it before
   classification.

3. OPNFV BottleNecks Project - Linux Foundation (September 2017 - Jan 2018):
   Contributed to the Bottlenecks project at OPNFV for developing a monitoring dashboard for long duration stress tests of VNFs.
   Used Prometheus for querying and as datasource, Cadvisor and Collectd plugins for collecting system metrics, Grafana for displaying the dashboard and Docker for installation
   on all VNF nodes. Presented at OPNFV Plugfest at ETSI France in June 2018.
