HELLO WORLD, I'M Harshadev S
Cyber Security & Computer Science Student | Web Developer
“Building secure and intelligent digital solutions.”
About Me
I am a final-year B.Tech student specializing in Computer Science and Cyber Security at the College of Engineering Kallooppara. Expecting to graduate in 2027, I am deeply passionate about the convergence of cybersecurity, intelligent web engineering, and AI systems.
My academic journey has driven me to explore the defensive and offensive facets of digital security while maintaining a strong love for building highly functional and secure web applications. I find joy in identifying system vulnerabilities, understanding classical cryptographic concepts, and building AI integrations that simplify cybersecurity verification processes.
My Career Goal: To join an industry-leading technology organization where I can leverage my security mindset, web development skills, and continuous appetite for learning to grow into a seasoned cybersecurity professional.

Projects
ScamPatrol AI
An intelligent scam and phishing detection system that accepts text statements or images and verifies their authenticity. Powered by the Groq Large Language Model combined with Tavily Web Search API to verify assertions in real-time, outputting a security verdict alongside an analytical reasoning report. Built with a robust FastAPI backend and a clean interactive web UI.
PixelVeil
A classical security-focused advanced steganography engine that hides data securely within cover images. Utilizes entropy-based region selection to hide messages in complex noise areas and SHA-256 seeded pseudorandom pixel shuffling to resist statistical attacks. Features ±1 LSB (Least Significant Bit) matching to prevent signature artifacts, maintaining a peak signal-to-noise ratio (PSNR) greater than 65 dB with 100% data recovery without needing deep learning models.
Services
Web Development
Building responsive, semantic, and modern client interfaces alongside basic API and backend systems. Proficient in crafting robust logic and premium designs utilizing clean standards.
Cybersecurity Web Development
Designing and developing web applications using secure coding standards. Preventing common vulnerabilities (OWASP Top 10) like XSS, SQLi, and misconfigurations during initial development phases.
Project Development
Assisting in building end-to-end academic and personal tech projects. Specializing in translating complex concepts (cryptography, AI logic, FastAPI) into working architectures.
Security Prototyping
Conducting security experimentations and prototype building. Testing ideas like steganography mechanisms, vulnerability tests, scanner integrations, and proof-of-concept building.
