DevOps Engineer with a strong foundation in analytical thinking and problem-solving, developed through rigorous preparation for the Indian Civil Services Examination. Currently, self-learning cloud and DevOps tools like AWS, Jenkins, and Docker showcase a passion for continuous learning and technology. Eager to apply determination, adaptability, and technical skills to drive innovation and efficiency in an entry-level DevOps role.

1)Master's Project:

 Enhancing Security Culture by Detecting Malicious URLs Using Machine Learning Algorithms

• Developed machine learning models to detect and classify malicious URLs, addressing threats such as phishing, malware distribution, and data breaches.
• Collected and pre-processed a dataset of benign and malicious URLs, extracting key features like URL length, domain information, path structure, and special characters.

Applied and compared several machine learning algorithms:

• Decision Trees: Built decision tree models to classify URLs using feature-based rules.
• Random Forests: Enhanced classification accuracy and reduced overfitting with an ensemble of decision trees.
• K-Nearest Neighbors (K-NN): Utilized distance-based classification for identifying patterns in URL features.
• Evaluated model performance with accuracy, precision, recall, F1-score, and AUC-ROC, ensuring the most reliable model was selected.
• The project resulted in a scalable, real-time solution for identifying malicious URLs, significantly enhancing security defences and contributing to the broader cybersecurity field by offering a machine learning-based approach to online threat detection.

2)AWS Resource Tracker- Tracking The Resource Usage by using Shell Scripting

• Developed a shell script to track and monitor AWS resources such as EC2 instances, S3 buckets, and Lambda functions.
• Automated regular status reports, resource inventory collection, and cost analysis.
• Integrated AWS CLI to retrieve real-time data and generate alerts for resource changes.

Components involved- S3, LAMBDA, Ec2, IAM

3)Implemented Three Tier Architecture - AWS

• Implemented a three tier Architecture that is highly available and scalable using Terraform and deployed the application on Ec2 Instances using the User Data Script

AWS Components Involved:

VPC, ASG, Route53, CDN , ELB, EC2, s3, NAT, API Gateway. 

4)End to End CICD Implementation - Jenkins

Implemented an end to end CI/CD pipeline for -java based application using Jenkins declarative pipeline. 

As part of the pipeline, I have implemented various stages such as Build , Unit testing, static code analysis, SAST, DAST, Creation of Docker Images, Deployment on Kubernetes platform using Argo CD

5)Cloud Cost Optimization- AWS

Used the combination of AWS cloud watch and Lambda functions To decrease the cloud cost by 25 percent.

Implementation:

Created lambda function in python, used the boto3 module to interact with AWS service APIs and this lambda function is triggered by Cloud Watch events.

This lambda function would watch for any unused EBS snapshots and either delete them or sends out notification to the snapshot owner.

Academic Counselor and Field Coordinator

Voice4girls- Hyderabad, India.

Cause- Children, Rights, Sexual abuse, Soft skills.

As an academic counsellor and field coordinator at Voice 4 Girls (V4G) in Hyderabad, I had the privilege of creating a lasting impact on the lives of adolescent girls from remote and tribal communities. My role involved organizing and leading 15-day residential camps in Gurukulas and Kasturba Gandhi Balika Vidyalayas. These are activity-based camps. These camps seek to increase the independence of girls by giving them the practical life skills and knowledge about sexual and reproductive health, Learn about their rights related to school, home, and community. Explore their careers, aspirations, and future planning. They also receive information about safety from violence and about their rights and responsibilities. As a field coordinator, my main focus was on creating a supportive and positive environment for both campers and counsellors. I led a team of counsellors, providing guidance, support, and training to ensure they could effectively engage the campers. As an FC, we need to act as a key link between campers, counsellors, stakeholders, and the VOICE team. When I signed up to intern with Voice 4 Girls, I had no idea that I was in for the experience of a lifetime. From getting trained by Voice staff,
traveling to the camp location and living in a rural school to train a bunch of teenagers, every small step was a lesson and one step towards a brighter future for adolescent girls.
I believe, “When a Girl Finds Her Voice, The World Around Her Begins to Change.”
