Need a fast Vue.js or PHP site that actually converts? I build responsive landing pages and web apps - lead routing, quizzes, calculators - that load in under 2 seconds and turn visitors into leads. 14 years, 5-star testimonials. I started in frontend and grew into fullstack, spending the last 3 years building an AI content automation api platform from scratch. That means I handle the hard edge cases - complex routing logic, multi-step quizzes, region-scoped data portals - that other developers hand back unfinished. Clients consistently tell me I finish what others give up on. Here's what I build: 🖥 Conversion landing pages - real estate, product, SaaS - with lead capture and routing 🧮 Interactive tools: quizzes, calculators, model-selection wizards 🔗 Custom web services: citizen portals, admin panels, data-collection forms ⚡ Performance-first builds: WebP images, lazy loading, BEM/SCSS, tested on real devices across Chrome, Safari, and Firefox Stack: Vue 3 / Nuxt 4, PHP, MySQL / PostgreSQL, JavaScript / TypeScript, Tailwind CSS, SCSS 5.0 rating for every completed project on Upwork. 100% Job Success Rate.
