About

A little context

Developer and business analyst based in Greater Philadelphia. I like building practical tools — security utilities, dashboards, automations — and I've spent the last few years turning messy operational problems into clean systems: databases that cut retrieval time by 30%, dashboards tracking 1,000+ records, and contract pipelines delivered 100% on time. Currently going deeper on full-stack development with TypeScript, React, and Next.js.

Check out my latest work

A few things I've built — from security tooling to browser extensions. More on GitHub.

File Integrity Monitor

Windows desktop security app that fingerprints critical files with SHA-256 and flags anything modified, added, or deleted. Baselines are HMAC tamper-sealed so they can't be silently edited, with scheduled scans, email alerts, and CSV/JSON reporting — pure Python stdlib, ships as a single .exe.

Tkinter

Invoice Generator

Professional-grade invoice system with customer management, a CLI, a FastAPI REST API, and ReportLab PDF generation — containerized with Docker and tested end-to-end through a GitHub Actions CI/CD pipeline.

RenameTab

Lightweight Chrome extension (Manifest V3) for renaming browser tabs on the fly — popup UI, content-script title override, and a privacy-first design that collects no data.
