Chrome, Edge, and Brave extension that reads verification codes and sign-in links from Gmail. A code can be filled or copied. A link opens only when you choose. Mail stays in the browser on the Gmail readonly scope.

TypeScript • React • Chrome Extension • Gmail API • OAuth

• One Gmail account is free. More accounts are a one-time purchase
• Background checks that speed up while a code field is on screen
• Auto-fill for a single box or split digit boxes, plus a Fill chip for recent codes
• Open link for a verification or sign-in URL, only after you click

Chrome extension that shows Zendrop product cost on a Minea product page, using the Zendrop session already in the browser.

TypeScript • Chrome Extension • Manifest V3

• Reads the visible Minea title and searches Zendrop
• Ranks matches with image, cost, and confidence
• Opens the Zendrop product page for the match you pick
• Never asks for or stores an auth token

Console script that posts every on-device Medal clip from the library, so a local backlog can be uploaded without opening each clip by hand.

JavaScript • DOM Automation • Browser Console

• Finds clips still marked on device and skips anything already handled in the run
• Opens the preview, confirms Post, and waits for the upload to finish before closing the dialogs
• Scrolls the library until it stops yielding new clips, then reports uploaded, failed, and elapsed time

Chrome extension that highlights game versions on SuperPSX when a matching patch exists in the PS-Game-Patch catalog.

JavaScript • Chrome Extension • Manifest V3

• Scans version tables for CUSA and PPSA title IDs
• Color-codes 60 FPS patches, other patches, and titles with no match
• Bundled index of 376 title IDs, regenerable from the latest patch release

Match Ente Auth verification codes to existing Apple Passwords logins in iCloudBridge.

Python • React • TypeScript

• Parses a plain-text Ente Auth export and matches each code to an Apple Passwords login by domain, issuer, and username
• Shows a setup key and QR code for Set Up Verification Code, because Apple's importer does not update a login that already exists
• Skips trashed, HOTP, and Steam codes, and leaves ambiguous matches and logins that already have a different code unchanged

• Sends the code as ref on the existing payment, trial, login, and API-key requests, with no extra network calls
• Wrote a guide for running a referral program on Stripe promotion codes today
• Specified the server-side attribution, rewards, and abuse checks for extensionpay.com
