You want to work with someone who has already built and scaled real products — not someone figuring it out on your project. Most web apps don’t fail because of bad ideas — they fail because they’re slow, hard to scale, or poorly built… and by the time you realize it, you’ve already lost users, rankings, and revenue. I fix that. I help founders and teams build fast, scalable web apps using React and Next.js — or improve existing ones that are underperforming. Recently, I improved a frontend to achieve a Lighthouse score of 90+, reducing load time by 40–60%, improving Core Web Vitals, and leading to a 20–30% increase in conversions — with sales growing from $100k+ to $300k+.saving thousands in Google Ads that were previously underperforming due to poor frontend performance. With 5+ years of experience in frontend and fullstack development, I focus on building products that don’t just work — but actually perform under real-world usage. If your app feels slow, messy, or hard to scale — I can quickly identify what’s wrong and fix it. 💡 How I can help • Build fast, SEO-friendly frontends using React & Next.js • Develop fullstack applications (Next.js, Django, APIs, databases) • Turn MVPs into scalable, production-ready systems • Fix slow, buggy, or hard-to-maintain applications • Improve performance (Core Web Vitals, Lighthouse optimization) • API integration & backend connectivity 🤖 AI Integration & Modern Features • AI-powered web apps (OpenAI / LLM integrations) • ChatGPT-style interfaces in React / Next.js • AI dashboards & data-driven UI • Adding AI features to existing SaaS products • Automation workflows using AI APIs I can help you add AI features to your product without overcomplicating your stack. 📈 Recent work & impact • Improved frontend performance → Lighthouse 90+ (faster load, better SEO) • Built fullstack app from MVP → scalable production system • Optimized performance bottlenecks and improved user experience • Developed clean, maintainable architecture for long-term scalability ⭐ What clients say • “Quick to understand the problem and suggest practical solutions” • “Delivers clean, scalable code — not just quick fixes” • “Strong focus on performance and real-world impact” • “Easy to communicate and reliable throughout the project” If you’re building a product — or struggling with performance — let’s start with a small task. If you’re not satisfied, I’ll refund it.
