// about
I'm a full-stack developer specializing in PHP, MySQL, JavaScript, Tailwind and AJAX on the web, and Flutter/Dart on mobile. I build secure, scalable applications — from business websites to fintech platforms carrying real money and real transactions.
Over 4+ years I've shipped everything from small business web apps to complex payment platforms with wallet systems, KYC verification, and third-party payment integrations. My approach favors correctness first: debit-safe flows, exactly-once transactions, and code that fails predictably.
Every project gets the same attention to detail on both ends of the stack, so the interface and the backend that supports it actually hold up under real usage.

// shipped systems
A platform to grow your online presence and access global digital services — social media growth, gift cards, and reliable virtual numbers.
A prediction market platform to explore global events, stake your insights, and get fast, secure payouts on mobile or desktop.
The Boostiphy mobile experience — airtime, data, bills and wallet payments, built with Flutter and backed by the same PHP/MySQL API as the web platform.
