Shawn — Software Engineer

I'm a software engineer and IT professional based in Atlantic County, NJ. I build full-stack applications and security platforms, and I run a local IT support practice for homes and small businesses.

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.

My Approach

Client Trust & Care: My goal is to provide clear, honest, and responsible support. Work is explained before it's performed, access is handled securely, and systems are treated with care as if they were my own.

Access & Security: Client credentials are never retained. Access is provided directly by the client or through temporary credentials that may be revoked after service.

Pricing & Billing: Pricing is discussed and approved before work begins. No charges are incurred without client confirmation. Payment is accepted via invoice, Zelle, or cash.
