@alansebastian
Final-year cybersecurity-focused software engineer building secure, scalable systems.
What I'm looking for
I am a final-year BTech in Computer Science (Cybersecurity) with hands-on experience designing and deploying secure, scalable full-stack applications. My work emphasizes integrating authentication, encryption, and containerization to produce production-ready systems.
Across internships in SOCs and penetration testing, I reduced SIEM false positives, conducted extensive vulnerability assessments, and automated incident response to improve operational efficiency. I combine practical security operations work with secure development practices.
My projects include a distributed encrypted cloud storage platform, a cryptographic QR verification system, an offline-first collaborative mobile app, and an ML-powered network anomaly detector — all demonstrating secure design, JWT/AES-GCM/RSA-based controls, and containerized deployments.
I am driven to join teams that prioritize secure-by-design software, cloud-native architectures, and measurable improvements in risk posture, where I can contribute both development and security operations expertise.
