About

Engineering with visual restraint, systems thinking, and delivery discipline.

I build and maintain production software across banking, trading, e-commerce, and business platforms. My work covers frontend architecture, API integration, testing support, and ongoing optimization. I also bring strong data structures and algorithms fundamentals from competitive programming and online judges.

Strengths

  • Frontend development with Vue.js and Quasar
  • API integration and third-party service integration (including Stripe)
  • Strong problem solving with data structures and algorithms
