## Work Experience
### Staff Engineer @ Kloudfuse
Jan 2021 – Present
Founding Engineer of a next generation full stack observability platform.

### Senior Software Engineer @ Amazon Web Services (AWS)
Jan 2020 – Jan 2021

### Senior Software Engineer @ Autonomic
Jan 2018 – Jan 2020 | Palo Alto, California
Transforming the transportation industry by building, scaling micro-services running on Kubernetes clusters.
- Owned multiple services that formed the core of the platform. These services handled vehicle/device registrations, metadata storage (Postgres) for all assets on the platform, provided search (ElasticSearch) and streaming change events (Debezium and Kafka).
- Horizontally scaled out above mentioned services to handle 30k ops at a latencies less than 5ms. This was instrumental in growing the capacity of the whole platform.
- Lead the design for making the platform multi-tenant across all services.
- Built a small team to handle the growing responsibilities of all the central services of the platform.

### Senior Software Engineer @ Autonomic
Jan 2018 – Jan 2020 | Palo Alto, California, United States

### Member Of Technical Staff @ Springpath
Jan 2017 – Jan 2018
- Design and implementation of Springpath’s cluster to cluster data replication over WAN using c++ and python. Implemented several optimizations like connection caching, asynchonous restartability of replications. Also implemented severals tools for data verificaion of replication, functional test suite for performing replications.
- Design techniques for WAN optimization/deduplication for replication to reduce network traffic, faster replications and more efficient disk usage.

### Senior Software Engineer @ Axcient
Jan 2013 – Jan 2017
Major contribution towards design, development and delivery of the deduplicating replication enginer for Axcient Fusion. This engine uses "merkle trees" to optimize storage and network costs for storing/retrieving vmware disk snapshots on the server.
- Designed and implemented backup client for Vmware device backups using python and C++. 
- Implemented thread pool to serve requests behind an nginx web server during a backup session. Nginx forwards requests from the client synchronously and the server thread pool schedules these requests on available threads.
- Implemented transaction manager using c++ for the next generation backup/disaster recovery product. Transaction manager maintains transactional semantics(either fully completed or nothing) across crashes and multiple drives during a backup session.
• Implemented an Asynchronous RPC mechanism using c++ for communication from the backed up device to the axcient server thats used during a backup session. Asynchronous RPC batches up rpc calls and flushes them together when an internal queue is full.
• Implemented several tools to parse and compare ntfs volumes against a volume backed up on axcient server. These tools were used to do integrity checks on the backed up data.
• Implemented heartbeat mechanism between axcient server and data center using c++ to communicate management level actions and responses. Primarily used at the time to pause/resume continous data transfer(a.k.a offsites) over WAN. Also, implemented pause/resume of offsites.
• Implemented consistent incremental backup in windows axcient client using c++. Involved reading NTFS journal file, getting open file handles and detecting changed files by reading NTFS metadata from the master file table.
• Implemented and deployed Container based development environment using Docker and Python to have reproducible build environments for developers and Jenkins builds.

### Member of Technical Staff @ CommVault
Jan 2012 – Jan 2013 | New Jersey
- Working on Commavult's bare metal recovery project using C, C++,. Added support for iSCSI disks in it. Also, added support for physical to virtual machine creation forMicrosoft Hyper-V.
- Working on an NFS based data recovery mechanism using C++ which enables users to mount their backed up data as a NFS file system. The data is backed up on Commvault's server and presented to the client as a file system. All NFS requests are served by our NFS server implementation that reads data from the back up.

### Software Engineering Intern @ Riverbed Technology
Jan 2011 – Jan 2011
Memory allocators (Tcmalloc and Jemalloc)

### Software Engineer(Development) @ Symphony Services
Jan 2007 – Jan 2008
Worked on various projects at the Volume manager layer of a thin provisioning file system.

### Software Engineer (Development) @ Intransa systems Private Limited
Jan 2006 – Jan 2007
Network time protocol, command line interfaces, Server failover handling.
