I don't just write code I build products that make money. I've built and shipped 3 SaaS applications from a blank screen to live products with Stripe payments and real users: → ClawFleet (clawfleet.app) - A hosting platform serving active customers → CutMagic (cutmagic.app) - SVG generation tool for Cricut crafters → ReadStash (readstash.app) - Twitter bookmark management platform Each one I designed, built, deployed, and maintained solo. That means I've handled every decision you're about to face database design, payment integration, user onboarding, deployment, scaling, and the hundred small choices that determine whether an app succeeds or dies in beta. What this means for you: When you hire me, you're not getting a developer who waits for a Figma file and writes code to spec. You're getting a builder who asks "will this feature actually convert users?" before writing a single line. I'll challenge bad assumptions early (before they cost you $5K in wasted sprints), suggest what to cut from v1 (because I've launched enough products to know what matters and what doesn't), and ship something your users can actually pay for not a demo that looks good but falls apart in production. My stack: Node.js, React/Next.js, Golang, PostgreSQL, MongoDB, AWS, Stripe, real-time systems (WebSocket/WebRTC), and enough ML to be dangerous when your app needs intelligence baked in. Best fit for: MVP development - Going from idea to launched product in 4-8 weeks SaaS applications - Multi-tenant, subscription billing, user management AI-powered web apps - Integrating ML/AI features into production applications Shopify app development - Custom apps for the Shopify ecosystem My commitment: I respond within 4 hours. I give you a realistic timeline on day one (not one you want to hear, one that's actually true). And I don't disappear mid-project check my response time stats. Let's build something people pay for.

I design clean, user-friendly web and mobile interfaces that make products easier to use and nicer to look at. Most of my recent work is with SaaS platforms, B2B tools, and dashboards - projects that need structure, clarity, and personality. I approach every project with a product-owner mindset: I care about how your product performs, not just how it looks. My goal is to help you build something that’s intuitive, scalable, and actually helps your business to grow. I also believe in long-term collaboration. Most of my clients stay for multiple projects because I make the process easy, reliable, and results-focused. ⚡️ UX/UI Design Expertise ⚡️ • Responsive web & mobile design that adapts beautifully across devices • SaaS dashboards & B2B platforms: turning complex data into clear UX • Product redesigns that improve usability, flow, and conversion • Clear visual hierarchy, smart UI patterns, and thoughtful typography • Design systems in Figma: scalable, consistent, and dev-friendly • Research-based UX: personas, user journeys, jobs-to-be-done • Platform-specific precision (Material Design, Human Interface Guidelines) ⚡️ Tools & Workflow⚡️ • Figma (from wireframes to prototypes, variables, and full design systems) • Adobe Photoshop, Illustrator, After Effects • ChatGPT, Midjourney, Recraft – for ideation and visuals • Used to agile teams, fast iterations, and smooth developer handoff ⚡️ Work Style⚡️ I’m structured, easy to work with, and genuinely care about my clients’ success.

Senior Product Designer with 8+ years in high-complexity B2B SaaS and a 𝗣𝗵𝗗 𝗶𝗻 𝗖𝗼𝗺𝗽𝘂𝘁𝗲𝗿 𝗦𝗰𝗶𝗲𝗻𝗰𝗲 (Distributed Systems, University of York, published at SC'23). I design from the data model up, not the screen down: my background is software engineering, so I understand database schemas, API structures, and system architecture - and my designs hold up when engineers implement them. 𝗪𝗵𝗮𝘁 𝗜 𝗱𝗼: - Enterprise product design → multi-role systems, compliance-heavy workflows, legacy modernization - Design systems at scale → most recent: 58 component sets, 6,880 variants in 3 months, published as an npm library with Storybook documentation - Sole-designer ownership → 0-to-1 from data model to shipped screens - Complex domains → ERP, logistics, circular commerce, document workflows 𝗥𝗲𝗰𝗲𝗻𝘁 𝘄𝗼𝗿𝗸: - SpecTec Middle East (maritime ERP) → unified crew management across 3 applications and 11 React sub-projects; adopted on 44 vessels for 2,000+ crew, replacing spreadsheet coordination - Okret (circular fashion SaaS) → sole designer, B2C mobile + B2B operations platform; first campaign: 2,551 validated takebacks, 39% account conversion; second campaign launched with near-zero support volume - Duxre (CRE SaaS + AI) → Design Lead; design system from scratch, React migration delivering 3 modules in 5 months - United Nations (gDoc 2.0) → unified global document workflow system, ~10,000 users 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸: Directly with founders, PMs, and engineers. I'm comfortable in the technical layer - schemas, API structures, system constraints - so my designs account for how things will actually be built, and handoff doesn't need reinterpretation. I'll push back on scope that creates technical debt. 𝗔𝘃𝗮𝗶𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆: 20–25h/week 𝗣𝗼𝗿𝘁𝗳𝗼𝗹𝗶𝗼: amarkovic.me
