Responsibilities include:

• Developing and implementing automated fuzzing techniques to mutate and smuggle HTTP requests, effectively bypassing Web Application Firewalls (WAFs). (Node.js, Golang, Python, PHP, Amazon AWS, Microsoft Azure, Google Cloud, Docker)
• Enhancing User Privacy Using Automatic Isolated Profiles in Browsers by adding an extra layer of security to browsers to prevent re-targeted ads from being displayed which use cookie syncing methods. (PriveShield)
• Conducting research on browser fingerprinting and implementing cookie syncing prevention measures to enhance user privacy and limit data sharing with ad exchanges to prevent re-targeted ads.
• Analyzing open source software vulnerability trends by examining Common Vulnerabilities and Exposures (CVEs) and Common Weakness Enumerations (CWEs), identifying patterns that inform security practices.
• Leading and participating in Capture The Flag (CTF) training sessions and organizing web security paper discussion groups to advance technical knowledge within our group.

Tapsi is a ride-sharing platform, similar to Uber, serving millions of users daily. I began as an intern, transitioned to a full-time role, and was later promoted to senior level. My contributions spanned DevOps and Software Development, including:

• Infrastructure Design: Co-designed the infrastructure for a large-scale project with over 20 microservices, collaborating across multiple teams.
• Performance Optimization: Enhanced product performance, boosting concurrent rides by 300% from 5k to over 25k.
• Response Time Reduction: Cut web application response times by 50% through optimized inter-service communication, using message queues, pub-sub systems, and stateless HTTP messaging (RabbitMQ, Redis).
• Deployment Automation & Containerization: Automated deployments and containerized the extensive codebase (Docker, Docker Swarm, Kubernetes, Salt, GitLab CI).
• Incident Management: Led the response to a hacking incident, detecting the attack, securing systems, repairing damages, and establishing preventive security protocols.
• Logging & Monitoring: Designed a comprehensive log and monitoring system for microservices (Elasticsearch, Prometheus, Grafana).
• Data Management: Implemented robust data storage, caching, replication, and object storage solutions (Redis, MongoDB, PostgreSQL, MinIO).
• Load Balancing: Configured load balancing to support millions of concurrent requests (Nginx, Traefik).
• Feature Development: Developed key web application features including user management, media services and a dynamic pricing model that adjusts based on real-time ride supply and demand analytics (Node.js, Python).

Contributed to the development of an innovative platform that utilizes movie clips to teach users new languages. My responsibilities included:

• Analyzing language difficulty through text mining of movie subtitles (Python).
• Full-stack website development (Django, HTML, CSS, JavaScript, Bootstrap, MySQL).
• Implementing video streaming functionality for the application (JavaScript).
