Portfolio — Quashawn
For employers, recruiters, and collaborators. In addition to local tech support, this site also serves as my professional IT portfolio. If you're here for help with a computer, head back to Atlantic IT Support →
I'm Quashawn, an IT professional and software engineer based in Atlantic City, NJ. I build full-stack applications and security platforms, and I run a small local IT support practice for homes and small offices in Atlantic County.
I care about writing clean, secure code that solves real problems. Everything on this site — the serverless API, the security headers, the quiz engine — I built from scratch. I approach professional work the same way: clear scope, honest communication, and careful attention to security and reliability.

Portfolio Projects
Securalith
Cybersecurity Platform
Problem it solves: small and mid-sized organizations struggle to track their public-facing assets and run consistent security checks. Securalith gives teams a single place to register domains, IPs, and networks, run automated scans, and review findings in a real-time dashboard with role-based access.
CompTIAPrep.net
AI-Powered CompTIA Study Tool
Problem it solves: CompTIA learners need fresh practice questions without paying recurring fees for a static question bank. CompTIAPrep.net uses the Gemini API to generate randomized practice questions for A+ Core 1 & 2, Network+, and Security+. Users get 10 free questions per subject daily with instant feedback and detailed explanations. The serverless API includes input validation, rate limiting, and retry logic.
Atlantic IT Support
Local Service Site & Portfolio (this site)
Problem it solves: a single front door for both local clients seeking tech help and employers/collaborators evaluating my work. Static site built with zero dependencies — no frameworks, no build tools. Implements OWASP security headers (CSP, HSTS, CORS lockdown), structured data for local SEO, WCAG 2.1 AA accessibility (skip nav, ARIA, keyboard support), and serverless backend functions. Deployed on Netlify with auto-deploy from Git.
