Emiliano Carrizosa

I support the people and the systems behind an organization. Front-line IT and access-control support on one side; the ability to build the tools that make the work run better on the other.

What I lead with is people. I read a room quickly, stay composed under pressure, and make technical things make sense to anyone — from a first-time visitor to a C-suite executive. Based in New York City. Available for IT, systems, and analyst roles, and select freelance work.

What I Do

I'm an IT and support professional, and what I lead with is people. The technical range is real — I support and secure systems, and I build the tools that make them run better — but the part that's hardest to teach is the part I'm best at: reading people, staying composed under pressure, and making technical things make sense to anyone across the table.

Right now I operate enterprise access control systems at Hunter College's Visitor Center, supporting 200+ people a day. There I was independently commissioned to design and build the department's first digital training platform — a full-stack app I rebuilt as a secure offline desktop application, presented to and approved by the College's VP of Administration, now in review with the Chief IT Officer for rollout. I hold a B.A. in Computer Science from Hunter College and CompTIA A+.

I'm looking to join a team in an IT, systems, or analyst role — at a law firm, a financial institution, or a tech company — where supporting people well and building the tools that make the work easier both matter.

Services

I take on select freelance work for independent professionals and small businesses — the same instinct as the technical work: figure out what someone actually needs, and deliver it clearly.

/01 Websites — Design & Build Fast, clean, hand-built sites — from a single landing page to a full multi-page presence. Designed to load quickly and read well on every screen.
/02 Copywriting Website copy, bios, and brand voice written to sound like you at your most articulate — clear, confident, and free of filler.
/03 SEO & Structure On-page SEO and clean site structure so the right people actually find you, and the page makes sense to a search engine and a human alike.
/04 Professional Positioning LinkedIn profiles, personal branding, and the narrative that makes you legible to the people who matter — clients, recruiters, decision-makers.
/05 Marketing Materials Sector-specific one-pagers, outreach templates, and brand collateral built to be used, not admired and forgotten.
/06 Outreach Strategy Email and outreach systems that turn a contact list into actual conversations — sequenced, personal, and built to get replies.

Hunter Visitors Center Training Simulator

2026
Independently commissioned by Hunter College Public Safety, I solo-built the department's first digital training platform: four training modules, a 30-question knowledge assessment, and scenario simulations replicating the EasyLobby interface. Because the material and its context are sensitive, I built it as a secure offline desktop application (Tauri, Rust, encrypted SQLite), designed around confidentiality, data protection, and the specific security considerations of a public-university safety operation. Shipped first as a React/Firebase web app, then rebuilt for encrypted offline deployment. Presented to and approved by the College's VP of Administration; now in review with the Chief IT Officer for institutional rollout.

Access Control & Audit System

Dec 2025 – 2026
A working prototype — screens and all — of a role-based access control system with tamper-evident audit logging for high-value inventory. Designed so a theft investigation that would mean hours of manual log review becomes a sub-second query, with behavioral analytics that surface internal access anomalies.

Infrastructure Security Audit

Jan 2026
A 47-page security assessment of a luxury retailer's infrastructure, built from passive OSINT alone — certificate transparency, DNS forensics, SPF analysis — with prioritized fixes and risk quantified against IBM benchmarks and the NY SHIELD Act. Sanitized here; full findings shared under NDA.

Private AI Processing Environment

Oct 2025
An air-gapped Linux environment that runs AI on confidential data with zero outbound traffic — verified by packet capture, not just policy. Network isolation and encryption built for legal, healthcare, and financial work that can't touch the cloud.

Multi-Layer Endpoint Security

Nov 2025
A daily-driver Linux workstation hardened with defense-in-depth — user compartmentalization, application sandboxing, browser hardening, and network controls — so a single compromise stays contained instead of becoming a total one.

Secure Cross-Platform OS Migration

Sep 2025
Zero data loss on a full Windows-to-Linux migration, with full-disk encryption added in the same window — a planned, verified methodology that scales to enterprise workstation transitions.

Mobile Device Security Hardening

Oct 2025
A hardened Android OS I run as a daily driver — verified boot, per-app isolation, and hardware-backed encryption that protects sensitive communications at the OS level.
