I'm early in my cybersecurity career and building my skills step by step. Along the way I've built full-stack web apps, worked with several kinds of databases, put together machine learning pipelines, and written network servers from scratch.
- 🎯 Focus: Learning cybersecurity, starting with the fundamentals
- 🌱 Currently: Building the core skills every cybersecurity professional needs
- 📚 Learning: Keeping up with new tools, techniques and threats in the field
- 🤝 Open to: Working with others on ideas and projects that help me grow in cybersecurity

Tools
- Full-stack web development: Building REST APIs with Express and FastAPI, connected to React and Next.js frontends
- Authentication & access control: JWT, bcrypt password hashing, Google OAuth 2.0 sign-in, role-based permissions and admin approval steps
- Auditability: Audit trails that record who did what and when
- Working with many databases: Document (MongoDB), relational (MySQL) and graph (Neo4j and Cypher)
- Network programming: HTTP and WebSocket servers written from scratch, real-time broadcasting, and WebRTC video calls
- Machine learning pipelines: Data cleaning, feature engineering, training, evaluation, forecasting and explaining model results with SHAP
- API integration & data visualization: Pulling in outside APIs, caching responses, handling rate limits, and showing results in interactive charts and maps
- Documentation: Clear READMEs with setup guides, API references and screenshots
