You need more than a pretty website. You need a digital product that earns trust, converts visitors, and grows with your business. That's exactly what I build.
You need more than a pretty website. You need a digital product that earns trust, converts visitors, and grows with your business. That's exactly what I build.
From startups to established brands across 10+ countries, I've designed and built products that don't just look good—they perform. Strategy, design, and code, all from one person.
Real projects. Real results. Here's what 5+ years of designing and shipping digital products looks like.
Every decision I make—from layout to animation—is driven by one question: does this help the user take the next step? If it doesn't convert, it doesn't matter how beautiful it is.
Ready to turn your idea into a product that actually works? Let's talk.
Clients across 10+ countries trust me to design and develop digital products that drive measurable results—more leads, more conversions, more growth.





Interfaces that users trust at first glance—and that convert. Every screen, component, and interaction is designed with one goal: making your product feel effortless while driving the results you need. From Figma prototypes to production-ready design systems, you get pixel-perfect design that developers can implement without guessing.
Led UX/UI redesign for AthenisAI app and built a reusable component library—improving form completion rates by 30% and cutting developer implementation time by 25%.
Websites that stop the scroll. High-performance web experiences with immersive 3D animations, fluid interactions, and pixel-level attention to detail—all optimized for speed. Your site won't just look impressive; it will load fast, rank higher, and keep visitors engaged longer.
Built an interactive portfolio with Three.js 3D visualizations and GSAP animations, achieving a 95+ Lighthouse performance score and 40% longer average session duration.
The engine behind the experience. Secure, scalable backends and automated deployment pipelines that keep your product running 24/7. APIs, databases, authentication, monitoring—the infrastructure your users never see but always depend on. One developer, full ownership, zero gaps between frontend and backend.
Built Aurin Task Manager's full backend with Firestore, implemented dynamic link system and automated CI/CD pipelines—reducing deployment time from hours to minutes.
Automate the work your team shouldn't be doing manually. AI-powered workflows, chatbots, and smart automations using GPT, Gemini, and tools like N8N and Make—so your team focuses on what matters while repetitive tasks handle themselves. Less manual work, faster response times, lower operational costs.
Integrated AI-powered chatbot and automated task reporting in Aurin Task Manager, reducing manual workload by 40% and response time by 60%.
