You will get a development-ready UX & UI design with a dev audit
Top Rated
Project details
You will get a development-ready UX/UI design tailored to your product — complete with a developer audit to ensure smooth implementation. My focus is on creating intuitive, user-centered designs that not only look great but are also fully prepared for handoff to developers.
🔹 What’s included:
• User flows, wireframes, and high-fidelity designs in Figma
• Scalable design systems and component libraries
• Clickable prototypes for testing and validation
• A developer audit to confirm technical feasibility and spot potential challenges early
🔹 Problems I solve:
• Beautiful designs that don’t translate well into code
• Gaps between design and engineering teams
• Poor usability and low engagement in SaaS/web/mobile apps
With over a decade of experience designing SaaS platforms, mobile apps, and enterprise solutions, I bridge the gap between design and development. You’ll get not just a stunning interface, but one that’s optimized for performance, scalability, and long-term success.
Let’s build a design that’s both user-friendly and developer-approved.

Kharkiv, Ukraine - 1:18 am local time
🔐 𝗞𝗲𝘆 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀:
1. Full-stack development — end-to-end product building, front to back
2. AI automation — streamlining workflows and processes with AI
3. Prototyping — fast, working proof-of-concepts to validate ideas
4. Hardening — taking over what you've already built and turning it into a production-grade solution
🌠 My background is in custom software development, and I spent a while working as a hands-on engineer. I was lucky enough to spend my entire career working with fast-growing, large-scale, and enterprise clients, representing an outsourcing vendor.
🌌 Apart from development activities, I was engaged in many others: interviewing engineers, participating in pre-sales, training programs, leading and driving development processes, and much more. I was always a company guy and was interested in and open to everything.
👴🏻 That’s where I matured as an engineer. I learned a lot along the way, saw how painful the software development process could be, and understood the pros and cons of different organizations, including where Fortune 100 companies struggle.
📺 I’m a professional engineer focused on delivering business outcomes for you — not a part-time freelancer juggling Upwork with a full-time job or doing it for extra income. I'm working with all types of clients and budgets.
✅ 99% Job Success Score; 100 + projects delivered — from idea to production-ready software
🛡 Expert-Vetted — interviewed and approved by the Upwork team
🚀 Fastest-Growing Upwork Profile Globally — $4M+ earned across multiple profiles since 2022
🌍 Most Recognized & Viewed Upwork Profile Worldwide
💰 Scaled 5 Upwork Profiles to $300K+ revenue each with strong inbound leads
🏢 Delivered Projects for Fortune 100 & Inc. 5000 Companies and UAE government
🧠 Led Pre-Sales, Estimations, Code Reviews & Tech Interviews for top-tier clients
💻 Even if we don’t end up working together, I’ll help you identify risks and guide you on how to make the product happen — because in the end, it’s all about mindset, not just coding skills.
💡 Answering a question how am I different in this competitive AI industry — the answer is simple: mindset. You can learn endless frameworks, libraries, languages — alright, cool, but mindset and deep understanding of this world outside and inside the industry is what really makes a difference.
