Hi, I’m Sadiel

Security engineer in progress.
IT foundation. Cloud focus. Builder mindset.

I work at the intersection of cloud infrastructure, security engineering, and automation.
Most of what I learn gets turned into a working system.

I prefer shipping over talking.


What I’m Building

I focus on practical security engineering problems:

  • Detecting cloud misconfigurations before they become incidents
  • Automating remediation instead of generating static reports
  • Building detection pipelines instead of dashboards that just look good
  • Designing lightweight SOC-style tooling for small teams
  • Using AI to accelerate development — not replace understanding

Everything here is built with production thinking in mind.


Featured Projects

CloudGuard Pro

Automated AWS security scanner built with Python and boto3.

Architecture Highlights:

  • Enumerates EC2, S3, IAM, and VPC configurations
  • Risk classification and severity scoring engine
  • HTML security dashboard generation
  • SNS-based alerting pipeline
  • Auto-remediation via Lambda + EventBridge
  • Modular, extensible service design

This project reflects a core security engineering loop:

detect → score → alert → remediate


ThreatWatch

Lightweight SOC-style threat intelligence dashboard.

Stack:

  • FastAPI backend
  • Live AbuseIPDB and OTX ingestion
  • Risk scoring and enrichment logic
  • Dockerized deployment
  • Ops-focused frontend

Built to simulate how small security teams operationalize threat intelligence.


Core Stack

Cloud & Infrastructure

AWS · IAM · EC2 · S3 · VPC · Lambda · EventBridge
Linux · Docker

Security

Nmap · Wireshark · Burp Suite
Threat intelligence integration
Log analysis and detection engineering concepts

Development

Python (primary)
FastAPI
JavaScript · React · Node.js

Automation & AI

OpenAI · Claude
n8n
AI-assisted scripting and workflow acceleration

AI is used as a force multiplier — not a shortcut.


Certifications

  • CompTIA Network+
  • CompTIA Security+
  • CompTIA CySA+

Certifications built the foundation.
Projects are building the depth.


Current Direction

  • Cloud Security Engineering
  • DevSecOps
  • Detection Engineering
  • Security Automation

If it involves securing cloud infrastructure and automating defense mechanisms, it’s aligned with what I’m building.
