I build secure, full‑stack web applications with encryption‑by‑design, clean architecture, and a strong commitment to technical documentation.
My work sits at the intersection of software engineering and information security, with a particular focus on applied cryptography, authentication, and network hardening.

Security
AES‑256, E2E encryption, JWT, ethical hacking, vulnerability analysis, system hardening.

A full‑stack web application with over 20 interfaces, built entirely with Node.js and SQLite — no external frameworks.
It integrates JWT authentication, end‑to‑end encrypted messaging (AES‑256), a semantic search engine based on TF‑IDF (Python), automatic encrypted backups, and identity verification.

• Repository: github.com/AveCesar1/Articora
• Complete technical documentation available in RESUMEN.MD (endpoints, data model, TF‑IDF, encryption).

I commit in verified, self‑contained modules.
Most commits represent a fully functional addition and often exceed 600 lines of code.
Lighter commits exist only when testing across different environments or when rapid cloud sync is required — never for trivial changes.

Commit messages follow a consistent format:

Project X.Y.Z: Description of the change

Where X is the main module, Y the specific area, and Z minor adjustments or fixes.
Example:
Artícora 4.2.4: file sharing via chat (AES‑256 E2E)

This keeps the history clean, searchable, and meaningful.

• Deepen my expertise in secure full‑stack development and offensive/defensive cybersecurity.
• Obtain industry certifications (Fortinet, Cisco) while contributing to real‑world security projects.
• Maintain the same level of rigorous documentation and architectural clarity in every system I design.
