Hire the Best Responsive Web Designers
in the United States

I help founders, teams, and creators build better software, improve their AI development workflows, and turn rough ideas into polished digital products. I’m an AI-native creative engineer working with Claude Code, Codex, Antigravity, and generative design tools. I use AI to accelerate the work, not to replace the judgment required for architecture, security, usability, maintainability, and launch readiness. Before moving into software and creative engineering, I served in the U.S. Air Force as an intelligence analyst supporting national security missions. That experience shaped how I work today: verify assumptions, identify failure points, communicate clearly, and never confuse something that looks finished with something that is actually ready. I can help with: - Claude Code coaching and workflow improvement - Debugging and improving AI-assisted codebases - React, Next.js, Astro, and TypeScript development - Website and application launch reviews - API integrations and automation - Performance, security, and reliability improvements - Architecture cleanup and technical debt - Polished AI-assisted visual assets I’m comfortable stepping into unfinished or difficult projects, figuring out what is actually going wrong, and explaining the solution without making the process more complicated than it needs to be. I also help clients get better results from AI development tools. Often, the model is not the real problem. The issue is the project structure, context, instructions, or workflow surrounding it. I can identify those weak points and help establish a more reliable way of working. Whether you need hands-on development, coaching, a technical second opinion, or help getting a project across the finish line, I bring technical judgment, disciplined analysis, and a strong creative eye to the work.

After 20 years across product design and creative direction, I bring both. Agency work trained me to design for persuasion and brand impact. Product design across 250+ projects taught me to design for clarity, retention, and real user behavior. The result is UX/UI work that looks considered, converts visitors, and gets built the way it was designed. ✅ 𝗖𝗢𝗥𝗘 𝗙𝗢𝗖𝗨𝗦 The clients I work best with are product teams and founders who need a UX/UI designer operating at both strategic and execution levels. I am equally comfortable running a UX audit, building a design system from scratch in Figma, or owning the full web design process from brief to handoff. My creative direction background means I think about brand, narrative, and conversion alongside usability. Industries: fintech and banking, SaaS and B2B platforms, e-commerce, healthcare, media, and enterprise software. ✅ 𝗠𝗬 𝗔𝗣𝗣𝗥𝗢𝗔𝗖𝗛 Every UX/UI design engagement starts with understanding the problem before opening Figma. I run a discovery phase covering user goals, business constraints, existing UX patterns, and competitive positioning. Wireframing and UX architecture come before any visual UI design decisions. This prevents the most expensive mistake in web design: building beautiful interfaces on top of broken user flows. I work in tight feedback cycles and deliver annotated Figma files with developer handoff specs, component documentation, and interaction notes so nothing gets lost between design and engineering. ✅ 𝗘𝗫𝗣𝗘𝗥𝗜𝗘𝗡𝗖𝗘 𝗕𝗬 𝗔𝗥𝗘𝗔 SaaS and Fintech Product Design: Core product experiences for fintech platforms, banking dashboards, and data-heavy SaaS products where UX/UI design must make complex information readable and actionable. Every engagement starts with UX research and flow mapping in Figma before UI design begins. Web Design and E-commerce: Brand-led marketing sites, conversion-optimized landing pages, and full e-commerce UI including product pages, checkout flows, and mobile web. CRO principles and A/B testing applied wherever performance data is available.

Creative Direction and Brand: Brand identity, visual language, logo design, and strategic positioning work that connects product design to business narrative. 🚀 SKILLS - Web Design - Figma - User Interface Design - UX & UI - User Experience Design - Mobile App Design - Generative AI (Chat GPT, Clause, Genini..) 💡 Want a free UX/UI audit before we discuss scope?
