Cybersecurity graduate focused on ethical hacking, threat modeling, risk and self-hosted Linux infrastructure. Past capstones include STRIDE/DREAD/OWASP threat modeling and bank BCP/DR with CVSS 3.1.
A living snapshot
What I'm up to now
- Practicing threat modeling and risk assessment for real systems I run and design
- Self-hosting and hardening Docker Compose stacks on Linux (logs, SELinux, secrets)
- Sharpening cybersecurity skills and staying job-hunt ready for security roles

Projects
Threat Modeling: BigMart E-Commerce Platform
Capstone- PG Cyber Security capstone (MIT SCC & Simplilearn): threat-modeled a Python/Nginx e-commerce store with STRIDE mapped to the OWASP Top 10 and DREAD risk ratings.
- Designed a defense-in-depth topology: perimeter firewall, WAF, IDS, DMZ application tier, internal database, and TLS/VPN trust boundaries.
- Specified controls for SQLi, credential theft, unauthorized access and DDoS — including input validation, MFA, RBAC, WAF rules and audit logging.
Business Continuity & Disaster Recovery: ZZIIPPEE Bank
Capstone- PG Cyber Security capstone: built a BCP/DR plan for a 1,200-branch bank with a threat catalogue and an impact × likelihood risk register (ransomware, SQLi, third-party breach).
- Scored a banking mobile-app remote DoS scenario with CVSS 3.1 and documented recovery priorities against that register.
- Defined RTO/RPO/MTO/SDO targets and a 3-data-center design (synchronous bunker + asynchronous DR replication) aimed at zero data loss.
Murder Mystery Discord Bot
Active- Fork of Ikbenmathijs' Murder Mystery bot with hardening for secrets and data: Discord token via environment variable, safer storage/log paths and atomic writes.
- Added an SQLite disaster-recovery mirror alongside JSON backups, plus retries on failed message sends.
- Fixed a crash in role-based permission checks and added a permission smoke test.
Minecraft Modpacks
Active- BedWars+ and SkyBlocks+: curated Forge modpacks for Hypixel BedWars and SkyBlock with HUD, inventory and performance improvements within server rules.
- Survival+: Fabric survival modpack focused on optimization for low- to high-end PCs, with pre-configured shaders.
MineVerse Minecraft Server
Archived- Custom Minecraft server and static site (mc.mineverse.in) that hosted a multiplayer community during its operational period.
- Archived — the server is no longer active.
