FileLocker v1.3.1.0 release
Inno Setup installer, SHA-256 checksum sidecars, GitHub Releases updater, and a fixed temporary download handle before verification.

Start with the receipts.
Release pages, live deployments, scans, and test counts do more work than another animated skills list.
Sentinel Tools on Cloudflare Workers
Four Next.js apps live on custom subdomains with a shared UI package, explainable scoring, CI, and 47 unit tests.
Open suiteCertificate scans on the site
CompTIA Tech+ and A+ certificate images are published, with Network+ and GitHub Foundations listed as current study targets.

The work splits into four lanes. Each one maps to shipped code, a live project, or a case study with implementation details.
Windows security tools
FileLocker is a shipped WinUI 3 / WebView2 app for local file protection and guided maintenance workflows.
- v1.3.1.0 ships through GitHub Releases with an Inno Setup installer.
- Current payloads use AEAD formats with Argon2id key derivation.
- System Care actions use scan, review, and apply flows instead of one-click cleanup.
Web security scanners
Sentinel Tools packages URL, repository, and file checks behind one hub with visible score deductions.
- LinkSentinel, RepoSentinel, and FileSentinel share one scoring package and UI library.
- FileSentinel hashes files in the browser and only sends a SHA-256 hash after an explicit lookup.
- RepoSentinel reads public GitHub repository data without cloning and masks secret-shaped findings.
Roblox gameplay work
My strongest Roblox work has been integrating team-built scripts and UI into playable builds.
- The Survivors ran through one engineering mainline so contributor work landed in a working build.
- Most fixes happened where two contributors' scripts met, not inside isolated features.
- Vacancy Filled focused on reusable interaction logic for horror pacing and progression.
Privacy and deployment experiments
I keep smaller builds around when they teach a specific constraint, like real-time overlays or deployment configuration.
- PrivacyLens separates capture, detection, and overlay rendering before full model work.
- This portfolio uses structured project data for pages, metadata, sitemap output, and tests.
- The contact route stays behind Turnstile while the static site deploys separately.

Each case study lists the stack, the constraint, the decisions, the outcome, and what I would improve next.

FileLocker
A WinUI 3 / WebView2 desktop app with a React interface for protecting local files, checking hashes, reviewing metadata exposure, managing startup apps, cleaning approved system locations, and running update checks without sending file data to the cloud.
Expanded FileLocker from an encryption utility into a broader Windows security suite with modern AEAD payloads, safer output choices, guided maintenance workflows, and a repeatable Inno Setup release path.

The Survivors
A collaborative Roblox project built by a team of scripters and UI designers. I owned the engineering mainline: building core mechanics, integrating everyone else's work, fixing bugs, and keeping the experience playable.
Acted as the integration point for the whole team. Scripters and UI designers handed me their scripts and interface work, and I assembled them into a single working game while resolving conflicts and bugs.

Sentinel Tools
A monorepo of four Next.js apps deployed on Cloudflare Workers: a product hub, a URL scanner, a read-only GitHub repository health scanner, and a browser-local file integrity checker.
Shipped four production apps on custom subdomains with a shared component library, a transparent 100-point risk model, CI, unit tests, and strict rules against overclaiming what a scan can prove.
