About

I'm currently working in Cohesity as part of the Data Hawk(Security) team specializing in the infrastructure to provide Data Classification insights to the users. Previously I worked as part of the Data Protection team with an emphasis on protecting virtual environments like VMware using CDP(Continuous Data Protection). I was responsible for the design and implementation of various Site Continuity Products CDP, Async and Sync replication, and Hot-Standby. I graduated in Computer Science at SUNY Stony Brook University. Previously, I worked at ORACLE in the Backup and Recovery team. I did my undergrad at IIT Kharagpur, India. I have 3 years of experience as a C developer in ORACLE. During this time, I also worked heavily with SQL and PL/SQL. I am proficient in low-level languages and am interested in areas of Operating Systems, Distributed Systems, and Databases. I am also familiar with agile methodologies. Competencies: C, C++, gRPC, Protobuf, JAVA, Python, SQL, PL/SQL

Senior Member Of Technical Staff

Jun 2014 – Jul 2017 · 3 yrs 1 mo

Member of a team responsible for developing and maintaining RMAN(Recovery Manager) and ZDLRA(Zero Data Loss Recovery Appliance), the backup and recovery products of ORACLE.
Built 'restore range' functionality for ZDLRA to calculate the recovery window of a database that determines the time in the past to which the database can be restored.
Added a feature to Oracle 'Block Change Tracking' by making it work through 'resetlogs'(an incomplete database recovery) to create faster backups by reducing I/Os.
Provided 'RMAN SDK' for Oracle 12c. This SDK is the minimal test infrastructure provided by RMAN to SBT library vendors to test their tape backup libraries.
Implemented RMAN 'client throttling' for ZDLRA which limits RMAN connections to ZDLRA based on various parameters depending on ZDLRA's capability.
RMAN creates backup pieces which have their own format. Improvised the existing 'piece dumper' to read the magic blocks of a backup piece and write these values to output in an understandable format.
Used C, SQL, PL-SQL languages and SQL*Plus tool during development.

Built Geocoding and Reverse Geocoding scrapers to convert a set of addresses into latitude and longitude co-ordinates and vice-versa
Created a Scrape Validation tool which analyses a scrape, compares it with previous scrape and provides snapshots at a level of city, state etc. The tool automates various aspects involved and sends a report to the entire team through email
Used existing Local Scraper Parsers to extract PBA(Phone Book Answer) results from scrapes of various non-local segments and created local query sets from non-local sets
