Most recently owned marketplace-wide work: **Lighthouse 32 to 68**, localization into 5 languages, Amplitude, and a **Next.js 14 to 16 migration**. Before that, delivered across a dozen client products — including a social platform refactor (**Lighthouse 60 to 90**) and a production React app restored from source maps and migrated to Vite, achieving **4× faster builds**. Looking for a product team where I can ship features, not rescue codebases. ## Contact - Email: [oleksii.morozov.w@gmail.com](mailto:oleksii.morozov.w@gmail.com) - GitHub: [https://github.com/Aler1x](https://github.com/Aler1x) - LinkedIn: [https://www.linkedin.com/in/oleksiim](https://www.linkedin.com/in/oleksiim) - Telegram: [https://t.me/alerix_dev](https://t.me/alerix_dev) ## Skills ### Frontend Next.js, React, TypeScript, Astro, Tailwind CSS, Motion ### Backend Node.js, Nest.js, Fastify, Drizzle ORM, Laravel ### Databases MongoDB, PostgreSQL, Redis ### CI/CD & Cloud Git, Docker, AWS, Vercel, Cloudflare, Railway ### Monitoring BetterStack, Amplitude, PostHog ### AI & AI Agents OpenAI, Anthropic, Model Context Protocol, OpenRouter, Claude Code, Codex, Cursor ## Experience ### Frontend Software Engineer at YachtWay September 2025 - August 2026 Remote - Enterprise yacht marketplace Owned cross-cutting frontend initiatives on a Next.js marketplace, taking platform-wide changes — localization, analytics instrumentation, and performance — from scope to production across a shared, fast-moving codebase.
