I'm dedicated to continually expanding my knowledge and skills as I grow into a proficient software engineer.
↓Hey there! I'm Adi Shankar Das — a passionate Cybersecurity Analyst and Full-Stack Web Developer who thrives at the intersection of security, innovation, and code. With certifications from Google and Microsoft, and hands-on experience in virtual roles at TCS, Mastercard, ANZ, and AIG, I've immersed myself in threat detection, network defense, and incident response.
I began my journey building full-stack applications and later ventured into the world of cybersecurity, where I now specialize in penetration testing, SIEM tools, and vulnerability assessment. I'm equally comfortable writing Python scripts for automation as I am analyzing failed login logs in SQL or tightening IAM policies using NIST frameworks.
Beyond tech, I enjoy content creation, AI experimentation, and community-building through blogging and open-source projects. I also speak three languages — English, Hindi, and German — and believe in lifelong learning.
If you're into cybersecurity, AI, ethical hacking, or full-stack dev, let's connect and grow together. I'm always open to collaborations, internships, or mentorships.
📩 Let’s talk tech, security, and future possibilities!
A collection of my recent work and contributions
Developed a command-line tool using Python and Google Gemini API that generates personalized, professional cover letters based on user input. Features include dotenv-based API key handling, interactive CLI prompts, and instant text generation using Gemini’s LLM. Ideal for developers and job seekers looking to automate their application process.
Designed and built a powerful TODO web app featuring drag-and-drop functionality, multi-project management, editable tasks, and real-time task movement across columns. Built using React, Zustand, and Tailwind CSS. Deployed with Vercel.
Designed and built a complete personal branding site with blogs, portfolio, store, e-book selling features, and responsive design. Includes dark mode and animation.
Conducted a vulnerability assessment on a Linux server with MySQL, focusing on access controls over three months using NIST SP 800-30 Rev. 1. Identified risks from networking, software faults, and OS vulnerabilities, recommending multi-factor authentication, regular software updates, and least privilege principles.
Secured file permissions for a research team’s directory in a large organization. Used ls -la to check permissions, modified file and directory access (e.g., chmod 440 for hidden files, chmod 700 for directories) to restrict unauthorized access while ensuring compliance with security policies.
Analyzed a DDoS attack on a social media marketing organization’s network caused by ICMP packet flooding. Implemented firewall rules, IP verification, and IDS/IPS systems to mitigate and detect future attacks, following NIST framework guidelines.
Developed a Python script to manage an allow list of IP addresses for a healthcare company. The script reads, updates, and removes IP addresses from a file, ensuring only authorized access to restricted content, enhancing security automation.
Documented a ransomware incident at a U.S. healthcare clinic caused by phishing emails. Captured the 5 W’s (Who, What, When, Where, Why) and noted operational disruptions due to encrypted system files, highlighting the need for employee awareness training.
Analyzed a SQL database to identify security issues in login attempts and employee access for a large organization. Wrote queries to filter failed logins after hours, specific dates, non-Mexico origins, and employees in Marketing, Sales, Finance, or non-IT departments.
Developed a full-stack astrology platform featuring horoscope generation, birth chart insights, blogs, and e-commerce integration. Includes blog search, donations, and authentication.
Designed a Microsoft Windows 11 UI using HTML5, CSS, and JavaScript, focusing on UI/UX and front-end development. View at https://aadishankardas.github.io/Windows11.github.io/.
Developed a Snake Game with FPS using Python, featuring a classic snake game experience with enhanced performance. Demo available at https://www.youtube.com/watch?v=mWdsj895CtQ.
