I am looking for entry level and junior level roles in Software Development and Data Science. I have previous experience of Data Science and Computer Vision working as a research assistant during my Masters in Computer Science for a year and building Software and Machine Learning Pipelines during my internship. Scroll Down to see some of my projects and know more about me.

I’M A DEVELOPER and a DATA ENTHUSIAST SKILLED IN WRITING CODE FOR SOFTWARE, DATA and ML PIPELINES.

The aim of this project is to recommend courses to prospective students in an e-learning platform.

## **Problem Statement**

Designing a course recommender system that will recommend courses to prospective candidates in an e-learning platform.

Client is an e-learning based platform with courses on various topics including Web Development, Data Science, Mobile Development, Cloud Services etc.

The Client has a user base of 10000 users and offers more than 100 courses.

## **Data**

The data consists of

1 -> Users Information.

2 -> Courses Information.

3 -> User – Course Interaction Activity.

## **Feature Building and Feature Store**

### **Requirements**

Download data stored in AWS and Create necessary features.

Design features and create a feature store.

### **Architecture**

![](/images/dcv22.drawio.png)

### **Explanation**

Downloaded data from AWS bucket using Boto3.

Created a Mongo DB Database Collection to store courses data.

Extracted, cleaned, and validated users and interactions data to create features in correct format.

Used terraform to create Infrastructure required to store the Features in AWS ( Redshift and Dynamo DB ).

Created  a feature store using Feast Feature Store and the AWS Infrastructure created.

Sync the feature store registries in AWS S3.

Building Docker File for the entire pipeline.

## **Model Training and Evaluation**

### **Requirements**

Create a model for recommending courses to students based on their interests and history of recorded activities.

Cater to new users with no recorded activities.

Scaling up as required.

### **Architecture**

![](/images/modelTrainingHLDv3.drawio.png)

### **Explanation**

Ingestion of features from feast feature store.

Split of Data into Train Validation Test sets.

Model Training using a hybrid recommender system.

Evaluation of the model and generating metrics.

Finding the best model whenever model is trained.

Upload of best model, metrics, artifacts to AWS S3 bucket.

Using a scheduler (Airflow) to schedule the pipeline.

Using Grafana and Prometheus to monitor statistics.

Building Docker file for the entire process.

Course Recommender System

The aim of this project is to predict human activities such as walking, running, standing, sitting from smartphone sensors data.

## **Problem Statement**

Designing a service that predicts user activities like running, walking, sitting etc. from smartphone sensors data.

Client is an electronics company who wants to develop a smartphone app to predict user’s activity.

### **Data**

The data consists of sensor’s data consisting of users performing activities of daily living, a 561-feature vector with time and frequency domain variables and
a ground truth label of performing activity.

### **DATA PIPELINE**

#### **Requirements**

Data stored in csv files stored in AWS S3 Bucket

Sensor’s data consists of streaming data so appropriate pipeline for it should be created.

#### **DATA PIPELINE ARCHITECTURE**

![](/images/data_pipeline_diagram.png)

Previous data stored in csv files are used to build the initial pipeline model.

Sensor's Data from Smartphone are connected to Apache Kafka Stream which takes the data and puts in in collection in Mongo DB

### **MODEL TRAINING PIPELINE**

#### **Requirements**

Create a model to predict activities

#### **MODEL TRAINING ARCHITECTURE**

![](/images/HLD_MODEL_PIPELINE.png)

Data Ingestion Component: - Responsible for ingesting the data from Mongo DB to our application and Split into Train, Validation, Test parts.

Data Validation Component: - Responsible for taking ingested data and checking validity (Data Missing, Numerical Columns Checking, Drift Calculation).

Data Transformation Component: - Responsible for  creating and saving a transformation pipeline ( Imputer, Scaling, Dimensionality Reduction) also Performs Target Encoding.

Model Trainer Component: - Uses a Linear SVM for Classification to train, evaluate train metric and save model, reports.

Model Evaluation Component: - Evaluates the model on Test Data and save reports.

Model Pusher Component: - Stores the best model to be used in production.

Model Prediction Component: - This part is used for prediction of Input Data.

For Model Deployment Docker File is created and deployed in an AWS EC2 machine using AWS ECR and GitHub Actions for CI/CD Pipeline.

Activity Prediction

The aim of this project is to develop a image search engine system that can search similar images and host them.

### **Problem Statement**

Designing an image search engine which takes input an image and can search and host similar images.

### **Data**

The Caltech101 dataset contains images from 101 object categories (e.g., “helicopter”, “elephant” and “chair” etc.) and a background category that contains the images not from the 101 object categories. For each object category, there are about 40 to 800 images, while
most classes have about 50 images. The resolution of the image is roughly about 300×200 pixels.
Provisions have been made to collect new labels and data through APIs.

### **Architecture**

![](/images/rev-img-se.drawio-3d4948a6.png)

### **Data Store Component**

Creation of AWS S3 folder to store image data for setting up hosting S3 link.

Creation of Mongo DB Collection to store Meta Data and Labels Information.

Creation of API links for image data collectors annotators to upload images and labels.

Creation of Docker File for the Pipeline.

Deploying the pipeline using AWS and GitHub Actions.

### **Model Trainer Component**

Ingestion of Data from S3.

Preprocessing the images for Model Training.

Employing Pre-trained Resnet34 architecture to generate embeddings.

Using Approximate Nearest Neighbors to build the embedding tree.

Upload Model and Artifacts to S3.

Creation of Docker File for the Pipeline.

Generating Embedding for the input using Previously built Model Architecture.

Employing Approximate Nearest Neighbors for similarity searching.

Get the publicly hosted S3 links of similar images.

Provide the links to the users.

Creation of Docker File for the Pipeline.

Deploying the pipeline using AWS and GitHub Actions.
