> I am currently a Data Scientist and have just completed my master's in Data Science from Lancaster University in the UK. I worked as a Data Scientist for 3 years at Infosys in India where I got a huge exposure to Python, Machine Learning, Deep Learning, Time Series Forecasting, Natural language processing, and automation using python. During my professional career, I leveraged my python skill to automate many tasks in my organization reducing human effort by almost 95%. I have been working with python for a very long time and have an experience about 7 years working with it. Also, I have used SQL databases quite a lot in my organization. I have a huge experience working with python and C++ and have developed many projects using these two. In terms of the cloud, I have used Amazon web service (AWS) for various operations of which a more recent one is for Object Recognition and resume selection.

> Since my childhood I have been in love with mathematics and have taught many of my friends and juniors during my college as well as school days. I have pertinent knowledge of statistics or mathematics required for Data Science as well as school-grade subjects.

> These days I am giving one on one R and Python sessions and helping students with their college assignments and project work pertaining to R, Python, Pandas, Numpy, Visualization, Statistics, Reinforcement Learning, GANs, Autoencoders, NLP ( Natural Language Processing ) and Machine Learning (Supervised, Unsupervised).

> SKILLS: Python3, Data Science, Machine Learning, Deep Learning, Natural Language Processing, Statistics, Azure data engineering, Azure databricks, azure data factory, azure data storage, azure machine learning pipeline, C, JAVA, C++, Object Oriented Programming (OOPS), SQL, Data Structures And Algorithms (DSA), Competitive Coding, Problem Solving, etc.

Experience

  • Data Scientist (Jun, 2022–Sep, 2022) at Forsberg, Lancaster, United Kingdom
    • Developed an ETL data engineering pipeline for anomaly (jamming) detection on GNSS data using Azure cloud services (ADLS Gen2, Azure Data Factory, Azure Databricks, Azure Functions, Azure SQL Server, link service, and Azure App Service), and anomaly detection was carried out using a statistical method: the modified Recursive Density Estimation (RDE).
    • Designed a statistical anomaly detection model to detect jamming, reducing the points of jamming inspection by almost 80%, and reducing the time complexity by more than 95%.
  • Data Scientist (Jul, 2018–Sep, 2021) at Infosys Limited, Hyderabad, India
    • Worked on the India’s taxation GST project in which I along with the team developed the tax forecasting model for future months using LSTM and Prophet model and applying some manipulation to create data for the pandemic time. Also, I developed a cluster-based model to classify the different companies into 5 different clusters based on the total tax and turnovers. Furthermore, I gained complete knowledge of the modelling pipeline from the collection of data and cleaning it using Hive Query Language and the making the model out the data and then using the resultant data into visualization in tableau for clients and automating the complete process via Jenkins and docker.
    • I also automated many tasks involved in our projects using python and reducing the human effort and time saving by a significant count.
    • Created a resume filtering POC using Google cloud and Azure services for the company.
    • Implemented .NET skills to provide the best service for clients and fulfil all requirements in web application in given time.
    • Developed web application in .NET SSIS.
    • Provided team with comprehensive written reports on applications for continued improvement.
    • Database migration from Windows SQL Server 2008.
