Hire the Best Clojure Developers

With 9+ years of experience, I help startups and product teams build production-ready frontend systems in React, Vue, Electron, and React Native. I use AI tools like Cursor and Codex to speed up development. Still, the real value is knowing how to keep AI inside safe engineering boundaries: clear requirements, practical architecture, automated tests, code review, and regression checks. My years of team-based development experience help me turn AI-generated output into reviewed, tested, maintainable production code. What I can help you with: 🚀 Fast frontend delivery: from requirement to production with clear milestones 🤖 AI-assisted development: Cursor/Codex workflows for implementation, refactoring, documentation, and test generation 🧪 Testing systems: Playwright scenarios and regression checks for reliable, fast delivery 💳 Payments: Stripe onboarding, checkout, subscriptions, discounts, payouts, and billing management 🖥️ Complex frontend apps: Electron desktop apps, dashboards, internal tools, and admin systems ⚡ Performance optimization: smoother rendering for high-frequency data updates and large datasets Why clients work with me: ✅ Senior frontend experience across React, Vue, Electron, Nuxt, and React Native ✅ Practical AI-assisted workflow without losing control of code quality ✅ Strong testing mindset for critical flows such as payment, onboarding, and checkout ✅ Clear communication, clean code, useful documentation, and predictable handoff ✅ Business-focused mindset: I care about product outcomes, not just code Selected experience: - Built Stripe onboarding, checkout, payment method management, subscriptions, discounts, payouts, and billing interfaces for a production education platform. - Created Playwright test scenarios for critical onboarding and checkout flows. - Supported marketing teams with UTM strategy, GTM tracking, analytics events, and Looker Studio / Databox reporting. - Built and maintained a reusable HTML email template system with 80+ production templates and SendGrid migration support. - Led frontend architecture for a Linux Electron application with high-frequency sensor data rendering, large file uploads, map/tree interaction, and offline deployment constraints. - Mentored frontend developers, reviewed pull requests, selected practical libraries, and built shared UI components. If you need a senior frontend developer who can combine AI speed, test discipline, and production delivery, let’s talk.
