About

Sandeep Joshi is a highly skilled distributed systems engineer with over 18 years of experience in various fields including Machine Learning, OS internals, Database kernels, Networking, and File system internals. He is currently working as a Data Science/Engineering professional at Kognitos, where he specializes in Semantic Parsing/Natural Language Understanding. Sandeep has a proven track record of building audio-related machine learning models at Amazon (Prime Video) to assess video quality. He also designed and built an asynchronous video processing pipeline to process bursty traffic at scale. Additionally, he was part of the core team that built one of the earliest Main Memory databases (Datablitz) at Bell Labs, which is now a well-known product in the industry. Sandeep has also made significant contributions to the development of the iSCSI protocol stack (target and initiator) while participating in IETF forum deliberations on the nascent iSCSI standard. He has built an FSAL for NFS-Ganesha and a Proxy server for Alba Object Store for Openvstorage. The product was deployed in US data centers and operated with high resilience. In terms of Sandeep's past work experience, he has worked as an independent consultant for a social media startup, where he built a social graph analyzer (patent-pending), did synthetic data generation, and developed features for trending topics. He also did NLP-based analysis (spacy, BERT) over a large corpus of financial documents. Additionally, he worked for an ed-tech startup in Southeast Asia, where he did software design consulting (design reviews, interviews, code analysis). Sandeep has also worked as a Senior SDE at Amazon Prime Video, where he built various features to assess video and caption quality. He worked with Applied Scientists to build a Voice Activity detector (VAD ML model) and a classifier that detects subtitles that are out-of-sync with the audio. He developed an async processing pipeline using Sagemaker and Lambda and built an ML model to detect the language spoken in the video. He also experimented with TTS models (text-to-speech) to generate controllable speech. Sandeep holds a Bachelor's degree in Computer Engineering from Pune Institute of Computer Technology. Overall, Sandeep Joshi is a highly skilled and experienced engineer with expertise in various fields, including Machine Learning, OS internals, Database kernels, Networking, and File system internals. He has a proven track record of building innovative solutions
