Alexey S.

Tired of design-to-dev handoffs where the vision gets lost? I'm Alexey — a designer-developer who builds the whole thing. 10 years of UX/UI design, 3 years full-stack, Top Rated Plus on Upwork. What clients have said about working with me: ⭐ "Alexey was the BEST freelancer I have ever worked with. His dedication and quality of work are phenomenal." ⭐ "Not only does he do excellent work, he also adds valuable ideas and contributions to make my product even better than I had in mind. He really understands UX." ⭐ "One of Upwork's most talented [designers]. He works incredibly hard and was able to understand my complicated ideas to help me bring them to life in a gorgeous, unique way." ━━━ WHAT I DELIVER ━━━ 🚀 SaaS MVPs end-to-end — design system, frontend, backend, auth, billing, deployment. Founder hands me a problem, gets back a working product. 4–6 weeks typical. 🤖 AI agents & LLM features — production-grade agents, RAG over your knowledge base, AI features inside existing apps. Reliable, monitored, cost-controlled — not just demo-pretty. 🎨 UX/UI design (standalone) — when you need a senior designer who understands business KPIs and conversion. Figma-first, design system thinking, mobile and web. ⚡ Frontend development — pixel-perfect React, Next.js, TypeScript. Component-based, type-safe, accessible. Pair me with your backend team or let me handle full-stack. 🌐 Webflow & custom websites — landing pages, corporate sites, e-commerce. 5+ years of advanced Webflow with custom interactions, animations, and code injections. ⚙️ Internal tools & automations — admin panels, dashboards, integrations between SaaS tools. The work that quietly saves your team 10+ hours a week. ━━━ WHY HIRING ONE PERSON BEATS A TEAM ━━━ Most full-stack developers build products that work but look generic. Most designers hand off Figma files and disappear. The handoff between them is where 40% of the original vision quietly gets lost. You hire me, you skip that. I designed it, so the implementation matches the intent. I built it, so the design respects what's actually possible. Iterations happen in hours, not sprint cycles. ━━━ HOW I DELIVER FAST WITHOUT CUTTING CORNERS ━━━ I use Claude Code as a core part of my engineering workflow. AI handles boilerplate, helps catch edge cases, and accelerates code review. I handle architecture, design, and the judgment calls that matter. Result: 2–3x the throughput of traditional freelancers at comparable code quality. You see preview links from day one. Daily progress updates. A working product in weeks, not months. ━━━ TECH STACK ━━━ Design: Figma (advanced design systems), user research, prototyping, usability testing, IA Frontend: TypeScript, React, Next.js, Tailwind, HTML5, CSS3, SCSS, Webflow Backend: Node.js, Python, PostgreSQL, Prisma AI/LLM: Anthropic Claude API, OpenAI API, RAG, vector DBs (pgvector, Pinecone), evals, structured outputs Infra: Vercel, Netlify, Railway, AWS, Docker, GitHub Actions ━━━ WHO I'M BEST FOR ━━━ - Solo founders who need a product, not just Figma files or a codebase - Early-stage startups validating an MVP without hiring a 4-person team - Companies adding AI features who want them to look as good as they work - Businesses that need a high-converting marketing site, fast Not a fit for: enterprise integration projects, very large legacy codebases, or buyers shopping purely on price. ━━━ NEXT STEP ━━━ Send me a message describing what you're building. If I'm a fit, you'll hear back the same day with concrete next steps. If I'm not, I'll tell you and try to point you somewhere useful. Sincerely, Alexey
