What I do

Modern Web Apps

I build fast, scalable, and reliable web applications using the most up-to-date frameworks and tech stacks.
From landing pages to complex frontend architectures, I focus on code quality and real-world performance — because faster apps mean better SEO, higher retention, and more conversions.

AI Tools Integration

I design and develop smart tools and full-featured applications powered by AI — from chatbots to automation systems — leveraging Large Language Models (LLMs) and custom integrations. Whether it's enhancing UX or streamlining internal workflows, or offering strategic consulting on AI adoption, I help businesses use AI to stand out and scale efficiently.

Business Applications

I create tailored CRM systems and business apps that adapt to your processes — not the other way around. Designed with usability, clarity, and productivity in mind, these tools simplify operations and improve internal efficiency, helping your team deliver more value in less time.

Mobile Apps

I craft mobile applications for iOS and Android. Whether it's a standalone product or a companion to your web platform, I ensure your app delivers speed, stability, and polish — so users keep coming back.

E-commerce Solutions

I build fast, scalable e-commerce platforms with custom storefronts, secure payments, and smart product management — designed to grow your business and boost conversions.

3D Experiences

I bring digital experiences to life with real-time 3D graphics and spatial interactions — from showcasing products in 3D to creating immersive brand storytelling. These experiences aren't just visually impressive — they increase time on site, user engagement, and memorability.
