Hire the Best Chrome Extension Developers
in Vietnam

I’m a Chrome extension developer who has been in the trenches for years. I survived the COVID era, the brutal Chrome Manifest V2 → V3 migration that wiped out thousands of extensions, and I’m still here — building, shipping, and maintaining powerful tools used by thousands of people. Built my own house by building a bunch of browser extensions over the years, thank you and love you, my clients! If you need someone who can design, build, scale, and maintain complex Chrome extensions, you’re in the right place. ✅Featured Products: ⭐ 𝐎𝐫𝐢𝐠𝐢𝐧𝐚𝐥𝐢𝐭𝐲𝐀𝐈 𝐀𝐈 𝐂𝐨𝐧𝐭𝐞𝐧𝐭 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐨𝐫 (20000+ users) ⭐ 𝐀𝐮𝐭𝐨 𝐅𝐨𝐥𝐥𝐨𝐰 𝐔𝐩 𝐈𝐭! ⭐ 𝐀𝐮𝐝𝐢𝐨 𝐁𝐫𝐚𝐢𝐧 𝐅𝐨𝐜𝐮𝐬 ⭐ 𝐄𝐚𝐫𝐧 𝐀𝐥𝐥𝐢𝐚𝐧𝐜𝐞 𝐂𝐨𝐦𝐩𝐚𝐧𝐢𝐨𝐧 ⭐ 𝐈𝐝𝐞𝐧𝐭𝐢𝐭𝐲𝐂𝐡𝐞𝐜𝐤 ⭐ 𝐒𝐢𝐭𝐞𝐣𝐚𝐛𝐛𝐞𝐫 ⭐ 𝐃𝐨𝐰𝐧𝐥𝐨𝐚𝐝 𝐀𝐦𝐚𝐳𝐨𝐧 𝐢𝐦𝐚𝐠𝐞𝐬 ⭐ 𝐒𝐨𝐜𝐢𝐚𝐥 𝐏𝐨𝐬𝐭 𝐌𝐚𝐭𝐞 ✅ Skills ⭐ JavaScript expert (with a serious love for jQuery) ⭐ Google Cloud Platform APIs – Google Sheets, BigQuery, Gmail, and more ⭐ Firebase – Authentication, Firestore, Realtime Database, Cloud Functions ⭐ Supabase services and integrations ⭐ AI integrations – OpenAI API and Google Gemini ⭐ Payment systems – ExtensionPay, Gumroad, Lemon Squeezy, Zoho Billing ⭐ LinkedIn & LinkedIn Recruiter scraping and exporting data to external platforms ⭐ Custom ad injection within Google search results ⭐ Amazon automation & scraping – Amazon storefronts and Seller Central ⭐ Email productivity tools – Gmail tracking and automated follow-up emails that work even while I’m sleeping!
