Webflow integration with a custom backend
Iryna has always delivered above and beyond our expectations. She take pride in her work, and even when a tool or technology is new to her, we would rather choose her over someone who claims to be an expert. Highly recommend.

Job Success

If you are tired of agency overhead, ghosting, and generic AI-generated code that breaks on mobile, let’s talk. I am a Senior Frontend Developer with 8+ years of experience and 4,200+ hours on Upwork, specializing in turning complex designs into high-performance, production-ready frontend architecture.
What Makes Me Different
Pixel-Perfect Figma-to-Code: I don't just "replicate" designs; I build them with absolute precision, flawless mobile adaptation, and smooth micro-interactions (GSAP, Framer Motion).
Direct & Fast Communication: I work individually on my own account. I am always available for video calls, respond super-fast, and keep projects moving without delays.
Seamless Team Integration: I easily jump into existing codebases, collaborating closely with backend engineers and product teams from early MVPs to mature SaaS platforms.
NDA-ready.

⚡ Faster delivery without sacrificing architecture or quality.

That’s why I focus on long-term collaboration: maintaining, improving, and scaling your website with bug-free code, flawless mobile adaptation, and smooth UX. If you’re looking for someone to stand by your side and support your project’s growth — I’m that person.
