# About
I'm a Communications & Electronics Engineer with over four years of field and infrastructure experience at CFE Transmisión, where I work across networking, wireless infrastructure, and low-level hardware recovery — from configuring MPLS-TP backbones to reviving a corrupted NAND flash partition byte by byte via U-Boot.
In parallel, I build full-stack web applications with Next.js, TypeScript, and Supabase— shipping production tools like a loan management platform with an integrated RAG chatbot. I sit at the intersection of hardware, telecom infrastructure, and software, which is a hybrid IT profile recruiters don't see every day.
Right now I'm expanding into cybersecurity and ethical hacking, building on my networking background to move toward vulnerability assessment and pentesting fundamentals.

Cisco AP2802i NAND Flash Recovery
Advanced low-level hardware recovery of a Cisco Aironet AP2802i with a corrupted UBIFS partition, preventing firmware upgrade. Executed entirely via U-Boot CLI and Linux tooling on Ubuntu 22.04.
- ▸Diagnosed UBIFS partition corruption on AP2802i (S/N: FJC2140M1N5) blocking upgrade ME 8.3→8.10
- ▸Analyzed 256 MiB NAND at hardware level: PEB=128KiB, LEB=126,976B, ECC=4-bit
- ▸Rebuilt all 8 UBI volumes from scratch (mkfs.ubifs + ubinize) with exact NAND parameters
- ▸Flashed image via U-Boot sequence: tftpboot → nand erase.part → nand write → ubi part
- ▸Manually marked 12 defective blocks (4 new double-bit ECC + 8 original)
- ▸Restored: Linux boots, WiFi radios init, CAPWAP join with IW3702 subordinate AP
- ▸Produced formal technical documentation (memoria técnica) for institutional records + Cisco TAC
jorge@kali-box:~/projects$ cat presta_base.md
Presta Base
Complete loan management platform for small lending operations, built with modern web technologies. Features 13 core modules covering the full lending lifecycle.
- ▸Integrated RAG chatbot using OpenAI GPT-4o-mini + pgvector for operational queries
- ▸Full audit logging and RLS policies for security and traceability
- ▸PDF receipt generation with jsPDF
- ▸Targeting Vercel deployment
