About Vladislav

⚡ Senior Front-End Developer · React, Next.js, TypeScript
🎨 8 years of design and art direction in parallel
⭐ 5/5 on Malt

Is your app slow, your website not converting, or do you want a senior dev who understands product and business challenges, not just someone who codes what they're given?

My real value isn't just writing code. It's understanding why we're doing it, for whom, and making decisions: what to keep, what to discard, what to simplify.
Before writing a line, I understand your product. Result: fewer back-and-forths, a more coherent product, delivered faster.

🔧 What I do
→ React / Next 16 (App Router, Server Components), TypeScript, Tailwind
→ Fast and clean interfaces: Core Web Vitals in the green, Lighthouse 90+
→ Smooth animations (CSS, Framer Motion, scroll-controlled)
→ API and headless CMS integrations (Strapi, Airtable, Prisma)
→ UX design and design system when you start from scratch
→ Pixel-perfect integration of your existing mockups

🧭 The added perspective
→ Co-founder and CTO of a B2B SaaS (KHube)
→ I built the front-end team and design system of a cybersecurity scale-up that grew from 20,000 to 500,000+ users in Europe
→ I understand your business constraints, not just your backlog

🚀 Typical missions
→ From scratch: MVP, SaaS, web applications
→ Redesign and modernization: migration, performance, redesign
→ Senior reinforcement in your team
→ Turnkey design + development, from mockup to deployment

🛠️ Stack: React, Next, TypeScript, JS, Tailwind, Framer Motion, SCSS, Figma, Headless CMS, Prisma, Vercel

    The unique aspect of this mission: we were building the product and the design system simultaneously as future designs were being prepared.

    This requires real adaptability and constant communication between the three poles. We implemented a complete and scalable Storybook so that each component could be documented and tested as we went, even when the final specs were not yet finalized.

    I learned Astro on the fly for this mission, which also allowed me to contribute to architectural choices with the CTO, particularly to keep the JavaScript bundle as light as possible by migrating some components to vanilla DOM with TypeScript typing instead of React.

    For visual validation, I adapted my workflow with AI tools to automate pixel-perfect audits via Playwright, cross-referenced with Figma specs.
    This allowed us to detect bugs that a simple glance would miss.
