At Fiverr, as a Freelancer delivering innovative software across Europe and Asia, I serve as a full-stack Software Engineer, building scalable web apps, e-commerce platforms, and AI SaaS products. I handle end-to-end development, from architecture to deployment, in Agile teams meeting high standards. Key contributions include 25+ Next.js/Node.js apps with React frontends (Tailwind CSS), Express backends, and MongoDB/PostgreSQL databases. Led a UK retail e-commerce dashboard with Stripe integration, boosting order speed by 40% and conversions by 25%. Excelled in e-commerce: Migrated a Shopify store with custom Liquid themes, cart recovery apps, and 95+ PageSpeed scores. Built WordPress/WooCommerce sites with Elementor, custom plugins, supporting 10K+ monthly visitors seamlessly. Pioneered AI SaaS, integrating OpenAI GPT into a Next.js/Node.js app on Vercel—cutting content creation time by 70% for SMBs. Daily tasks: RESTful/GraphQL APIs (JWT auth, Socket.io real-time). Security (OWASP), optimization (Redis caching). Cloud deploys (AWS/Heroku/Vercel) with CI/CD (GitHub Actions). Testing (Jest/Cypress), code reviews, 24/7 support. My working experience ensures enterprise-grade code, fast delivery, and client success—proven by 5-star feedback and repeats.
