About Xavier Romero

Now

I am a civilian accounting clerk for the Department of the Air Force at McGuire, in New Jersey. My job is to check that transactions match their paperwork, and to find out why when they do not.

I finish a B.S. in Financial Technology at NJIT in December 2026, after an A.S. in Cybersecurity from Union County College. I have worked continuously since 2021 through both degrees, including training new hires at Amazon and supervising shifts at CVS.

Learning

Finance is what I do every day. Data, security and software are what I am still learning.

For data work I use Python through Anaconda, in Jupyter notebooks with pandas and NumPy, and SQL with MySQL. In NJIT coursework I have used them to analyze financial data, build a financial model, complete a machine learning assignment and design a database. I also use SQL at work.

Cybersecurity, AI and software are the areas I am working to get better at. My associate degree covered the foundations of security, and I teach security awareness to Civil Air Patrol cadets. The web applications on this site are how I practice building software. I built them with AI coding assistance, and each write-up says where the result falls short.

Interests

Working in Air Force finance showed me how a large government organization runs from the money side, and it made me curious about the rest: how programs are funded, bought and managed.

What interests me most is space operations, and how the Space Force runs them. GPS, satellite communications and launch each depend on spacecraft, ground stations, software and people working as one system, and each is paid for through public budgets and acquisition programs.

I also follow markets and fintech, the subject of my degree, along with defense, national security and cybersecurity.

Where I’m headed

Those interests are why systems engineering appeals to me. It is the discipline of getting many parts, and the people and budgets behind them, to work as one system. I am learning toward it.

I am looking for finance and data analyst roles starting January 2027. Government, defense and aerospace interest me most, because the work sits close to the systems I want to understand. I am based in New Jersey. New York or New Jersey is my preference, and I am open to relocation.

How this site is built and secured

The site is a set of static pages built with Astro and served by Cloudflare Pages, on the free tier. I built it with AI coding assistance.

Fonts, styles and scripts are served from this domain. The only third-party code is Cloudflare’s own: the bot check on the contact form and cookieless page analytics.
A content security policy allows no inline scripts or styles and no framing by other sites. Connections are forced to HTTPS.
The contact form posts to a small Cloudflare Worker. It verifies the bot check on the server, limits how often one address can submit, caps field lengths, and strips line breaks from the name and email so a message cannot inject email headers.
API keys are stored as Worker secrets and are not in the repository.
The site sets no cookies and has no accounts.
The photographs are NASA images, credited where they appear. The drawings, diagrams and code panels were made for this site. NASA does not endorse this site.

Each project write-up has its own section on security and known limitations.
