About

I'm a Computer Science and Mathematics graduate from Wittenberg University (May 2025) with a cybersecurity focus and a CompTIA Security+ certification. From June 2025 to February 2026 I worked as a Tier 2 managed services specialist at NetX IT Solutions, supporting 150+ client organizations — then shifted my full focus to software development.

I'm drawn to the backend and reliability side of software — building APIs, designing data models, and understanding how systems behave under real conditions. My most recent project instruments a C# ASP.NET Core API with Prometheus and Grafana to track SLIs and error budget burn rate in real time, with Locust running load tests in the background. I like knowing why systems break, not just that they do.

When I'm not coding I'm on a volleyball court — 4-year varsity athlete, back-to-back conference champion (2023 & 2024).

Projects

Job Application Tracker
Live

A full-stack web application for tracking job applications end-to-end — statuses, contacts, notes, cover letters, and a real-time metrics dashboard surfacing total applications, interviews planned, offers received, and response rate. Built with a normalized 4-table PostgreSQL schema and a secure JWT + email 2FA auth system.

Python FastAPI PostgreSQL SQLAlchemy React REST API JWT Auth
ASP.NET Observability API
Local / GitHub

A C# ASP.NET Core REST API fully instrumented for reliability observability. Prometheus scrapes live SLIs — error rate, latency, request volume — and tracks them against a configurable SLO target. A Grafana dashboard surfaces real-time error budget burn rate so you can see reliability health at a glance without manual querying. Locust runs load tests in the background generating realistic traffic. Everything spins up with a single Docker Compose command.
