👋 Hello, I'm Debasis Biswas
About Me
3rd-Year BCA Student • Cybersecurity, DevOps, and Cloud Security Enthusiast
I'm a 3rd-year Bachelor of Computer Applications (BCA) student at B.P. Poddar Institute of Management and Technology, focused on cybersecurity, DevOps, cloud security, and DevSecOps.
My journey in technology is driven by curiosity and a commitment to engineering secure, reliable, and scalable systems. I prioritize shift-left security, automated testing, and host hardening over manual reactive patching.
DevSecOps
Secure CI/CD, security automation, vulnerability gates, and infrastructure workflows.
Cybersecurity
Security research, penetration testing, host hardening, and threat modeling.
Cloud Security
Cloud posture, access control, serverless security, and safe container deployments.
DevOps
Infrastructure as Code, container orchestration, logging, and operational reliability.
Tech Stack & Tools
Proof over buzzwords: I deploy, secure, and operate systems — automate delivery, harden hosts, and keep services reliable in real environments.
Infrastructure & Operations
Experienced in managing production-like systems: host hardening, networking fundamentals, and reliable edge routing.
Production servers & daily driver
Production deployments & tooling
Enterprise Linux familiarity
Performance tuning, rc.conf/rc.d service management, networking
Reverse proxy, routing, TLS termination
Automatic HTTPS, simple reverse proxy
DNS/CDN/WAF at the edge
DevOps & Delivery
Automate build → test → deploy. Prefer repeatable infrastructure and clear runbooks over hero debugging.
Containerized apps & reproducible environments
Automated pipelines (build, test, deploy)
Idempotent provisioning & configuration
Security & Hardening
Security is operational: least privilege, sensible defaults, patching discipline, and tight exposure at the edge.
Security testing environment (not a production OS)
SSH, firewalling, service isolation, least privilege
Certificates, secure headers, safe secret handling
OWASP-minded reviews and defensive configs
Backend & Data
Build APIs and automation that behave well in production: logging, sane defaults, and predictable deployments.
APIs and backend services
Automation, scripting, tooling
Relational modeling and query fundamentals
Document data when it fits
Compute/services basics
Frontend (supporting role)
React
Next.js
Vite
JavaScript
HTML5
CSS3Featured Projects
Hands-on systems, security tools, and open-source applications I have architected, secured, and released.
Kyreqo
TypeScriptA modern API testing platform built with React, Django REST Framework, and PostgreSQL.
CVE Scanner CLI
PythonA fast CLI tool for searching and displaying CVE details by ID or keyword using public vulnerability databases.
Cybersecurity Labs
JavaScriptReproducible Docker-based labs covering Linux, web application, and DevSecOps attack and defense techniques.
Phishing URL Checker
TypeScriptA security-focused URL analysis tool that uses VirusTotal threat intelligence to identify suspicious domains.
