Hi, I'm Anastasiya Skybchenko, a UI/UX designer focused on app design, mobile app design, and web design for startups and product teams. My work combines UX and UI design, interaction design, and structured software design thinking, so every screen supports usability, clarity, and the product's goals. 📱 Mobile App Design I design complete iOS and Android apps from wireframes to high-fidelity mockups, following native platform guidelines for iOS Human Interface and Android Material Design. I create mobile-first responsive and adaptive layouts, onboarding flows, dashboards, and feature-specific UX, and I handle interaction design for multi-step processes and complex user journeys. I prototype in Figma so flows can be usability-tested before development starts. 💻 Web & SaaS Design I design SaaS dashboards, admin panels, and complex software systems, and I handle website redesign with improved UX and UI structure and stronger conversion logic. I build responsive web design for desktop, tablet, and mobile, work on B2B platforms, enterprise software, and data-heavy interfaces, and design landing pages and marketing sites with a strong conversion focus. 🛠 Tools & Process I work primarily in Figma, using auto layout, components, variants, design tokens, and prototyping.

AI can build your app in a weekend. It still can't make it investor-ready. I architect, code, and ship. What used to take a small team, I deliver with AI as my force multiplier and 18 years of judgment as the quality filter. Three startups built from scratch, from zero codebase to production. 🔸 𝐖𝐇𝐘 𝐈 𝐀𝐌 ▸ 18 years in software engineering ▸ 3 startups built from scratch to production ▸ Top 3% of Talents on Upwork ▸ I know what AI makes faster and what it makes worse 🔸 𝐖𝐇𝐀𝐓 𝐈'𝐕𝐄 𝐁𝐔𝐈𝐋𝐓 (platforms from scratch) ▸ Quote-Bot, through Rendered Source (InsurTech) - Omni-channel insurance sales CRM with phone, video, email, and chat built in. Per-agency isolated deployments on AWS. AI deal prediction (SageMaker, then ML.NET) and chatbot (Lex, then ChatGPT API) - switched tools twice when simpler options proved better. Architecture designed for SOC2/HIPAA from day one. Team of 5. MVP in 4 months, evolved over 4 years. ▸ YEZ (Automotive) - Car repair booking platform that aggregates spare parts pricing from 10 supplier APIs across 150M+ records into instant quotes. Six apps: customer portal, repair shop dashboard, spare parts management, CRM, CMS, and SEO-optimized public site. Microservices on Docker with CI/CD. Team of 4. MVP in 6 months including a pivot. ▸ Ecoplaces (Hospitality) - Countryside hotel booking platform - guest-facing search and booking, hotel owner management dashboard, SEO-optimized CMS for marketing, and back-office CRM for order management. Team of 2. MVP in 3 months, full product in 1 year. 🔸 𝐇𝐎𝐖 𝐈 𝐖𝐎𝐑𝐊 𝐏𝐡𝐚𝐬𝐞 𝟏 - Architecture Review | $3,000-$5,000 fixed | 2-3 weeks Before I build, I do a 2-week blueprint. If we proceed, it applies to your first month. Deliverables: ▸ Technical architecture document (system design, data model, integration map) ▸ Tech stack recommendation with justification ▸ 90-day MVP roadmap with realistic timeline ▸ Team hiring plan (roles, seniority, timing) ▸ AWS infrastructure cost projection ▸ Compliance gap analysis (SOC2, HIPAA, other frameworks as applicable) A concrete plan you can act on with or without me. 𝐏𝐡𝐚𝐬𝐞 𝟐 - 0→1 Platform Build | $10,000-$15,000/month | 10-20 hrs/week ▸ This is the core engagement - what I did at Ecoplaces, YEZ, and Quote-Bot (as lead architect through Rendered Source). I architect, hire the right team for your specific project, set up infrastructure, establish Agile processes, and lead the build to MVP in 90-120 days. ▸ What you own at the end: a production-ready platform - not a vibe-coded prototype that needs a $200K rebuild six months later. A hired team that continues without me, and investor-ready architecture. No equity required. ▸ I don't hand you to a project manager. You talk to me throughout. 𝐏𝐡𝐚𝐬𝐞 𝟑 - Ongoing Strategic CTO | $6,000-$10,000/month | 5-8 hrs/week ▸ Post-launch oversight: architecture decisions, team mentorship, investor due diligence support. ▸ Stacks naturally after Phase 2. 🔸 𝐇𝐎𝐖 𝐈 𝐓𝐇𝐈𝐍𝐊 "The best is the enemy of the good." - Voltaire KISS (Keep It Simple, Stupid) and YAGNI (You Ain't Gonna Need It) govern every engagement. I push back on overengineering in all its forms: ▸ Teams building proprietary frameworks instead of shipping ▸ Aiming for 100% test coverage before product-market fit ▸ Adopting hyped tech without technical justification ▸ Overusing design patterns until the code becomes unmaintainable I build what you need to win your market today, with a foundation that scales when you actually need it. 🔸 𝐁𝐄𝐒𝐓 𝐅𝐈𝐓 ▸ Founder without a CTO or technical co-founder ▸ Built something with AI tools and need to harden it for production - this is my sweet spot ▸ Need AI features integrated the right way (LLM APIs, RAG, automation) with compliance in mind ▸ Funded (pre-seed through Series A) ▸ Strongest in InsurTech and other regulated, compliance-heavy platforms (HIPAA/SOC2 architecture) Have developers but no technical direction? ▸ Phase 2 covers that. Need to validate architecture before committing to a full build? ▸ Start with Phase 1. Built something with AI tools and not sure if it's production-ready? ▸ Phase 1 tells you exactly where you stand. 𝐍𝐨𝐭 𝐭𝐡𝐞 𝐫𝐢𝐠𝐡𝐭 𝐟𝐢𝐭: companies with an existing CTO, staff augmentation needs, or mobile-only products. 🔸 𝐋𝐄𝐓'𝐒 𝐁𝐔𝐈𝐋𝐃 Tell me what you're building and what stage you're at - I'll let you know if I can help and which Phase fits.
