I'm Jodrick Marquinez, a SOC analyst based in New York. I monitor and triage security alerts, investigate suspicious activity across logs and network traffic, and support incident response from detection through containment. CySA+ and Security+ certified, with a strong foundation in networking, Active Directory, and cloud (AWS & Azure).
I focus on the core of security operations: turning high volumes of alerts into clear, well-documented decisions. My foundation across networking, Active Directory, Linux, and cloud (AWS & Azure) means I don't just see an alert — I understand the system that raised it, which is what separates a false positive from a genuine intrusion.
I document every investigation and detection so the analysis is clear, repeatable, and easy for the next analyst to act on.

An offline-first smart-home hub that runs a local LLM (Ollama) on Home Assistant — full voice and automation control with no cloud, no telemetry, and nothing about the household leaving the building. Built for people who treat privacy as non-negotiable, with a camera-free elder-care monitor at its core.

A real-time neural voice-conversion pipeline that began as a VRChat experiment and turned into a firsthand study of synthetic-voice fraud. Speech in, a different voice out — fast enough to feel live. I chained Whisper (STT) into ElevenLabs synthesis, then spent the project collapsing end-to-end latency until the illusion held.

An e-commerce platform serving a niche technical community. I designed and built the full storefront — a custom multi-step product configurator in vanilla JS, Stripe and PayPal gateway integration, and an extensive front-end / UX engineering effort on top of WordPress + WooCommerce.
Investigation writeups, detection notes, and lab breakdowns — how I triage alerts, read the evidence, and reason through an incident. In a SOC, clear analysis matters as much as the catch.
Walking a suspicious-email alert from SIEM notification to verdict — header analysis, URL detonation, IOC pivoting, and the escalation call.
Turning raw log activity into a tactics-and-techniques story that other analysts can follow — and reuse as a detection.
From noisy raw events to a tuned correlation search — the queries, the false positives, and how I cut the alert fatigue.
More writeups in progress. Each article is just a copy of a row above — duplicate it, swap the title, date, category, summary, and link.
