Revature

Behind the payment.

Software Developer · Reston, VA

I joined a payments team building Ruby services and React interfaces for major banks. My day-to-day work ranged from RESTful APIs and Buy Now, Pay Later features to loan-policy updates and bug fixes.

I also developed a client’s first consumer loan application, from the initial build through its public launch, within a year.

Hexaware Technologies

The work behind
every release.

Technical Architect · Iselin, NJ

At Hexaware, my focus shifted from building applications to the systems that delivered them for Fannie Mae.

That meant maintaining Jenkins and IBM UrbanCode Deploy workflows, provisioning AWS infrastructure and supporting the early adoption of GitLab and Terraform.

Arista Corporation

Ready for the client.

Testing Technician · Fremont, CA

At Arista, I prepared industrial PCs for pharmaceutical, biotech and life-science clients.

I tested and calibrated hardware, set up client environments on Windows and Linux, then cleaned and packed PCs for shipment. ThinManager and Q8 Edge OS were part of that hands-on work.

FROM BENCH TO SHIPPING

Calibrated PCs and ran burn-in, memory and I/O tests.

Probability modeling

Monte Carlo
simulations in Python.

I built Python tools to compare game outcomes over millions of simulated trials, with a tkinter GUI and live data visualization in matplotlib.

HOW SIMULATION WORKSSelect a step

Define the game rules in Python, including which outcomes are possible and how each round is played.

Perspective

Professional
profile.

My career began in hospitality, retail and entertainment. Those roles shaped how I listen, communicate and follow through on commitments.

In engineering, my interests extend beyond the application itself to release infrastructure and the hardware it runs on. That broader perspective shapes how I investigate problems and make decisions about reliability and maintenance.
