Your AI demo worked. Then it met real users, real data, and real edge cases, and now nobody trusts its output. That gap between "impressive in a call" and "reliable on Tuesday" is where I work: agents, RAG, memory and evaluation for teams who already have something running and need it to actually hold. Most profiles here promise accuracy. I publish measurements instead, including the ones I lose. My open benchmark compares seven retrieval systems across 100 probes with the negative results left in, on the axes where my own engine is beaten. If someone tells you their AI is great without showing you how they measured it, they are guessing, and you are paying for the guess. You probably need me if: • Your agent produces work but never checks it, so a human re-reads everything anyway. • Your RAG returns the right fact in the wrong context, which is worse than returning nothing. • Model costs climb while output quality does not, and nobody can say which change caused what. • Your prototype passed a demo and now fails quietly in production, and the traces do not explain why. • Your team cannot tell whether last week's prompt change made things better or just different. What I do: • Evaluation you can act on. I build the harness that tells you whether a change helped: regression tests on prompts, quality scoring on real tasks, cost per useful output tracked next to quality. Without this, every AI decision after launch is a guess. • Agent and RAG rescue. I read your traces, failed outputs, architecture, model routing and latency, find the actual bottleneck rather than the obvious one, and fix the smallest slice that makes it reliable. • Memory and context that survives. Long-term memory, retrieval and context design so agents keep state across sessions instead of restarting the conversation every time. • Model selection with a margin attached. I test frontier models (GPT, Claude) against open-weight and hosted alternatives on your workload, not on a leaderboard, and tell you which one earns its cost for your specific task. Proof, not adjectives: • Ran an autonomous agent in production for a full year: it generated its own content, held real conversations daily, and kept a memory of its relationship with each individual person. • Built a compliance agent that runs inside a bank's own controls, where every output has to trace back to the evidence that produced it. • Built language-model surveillance in regulated New York capital markets in 2019, stored so a regulator could verify it years later. It won an Algorand grant. • Trained roughly 650 practitioners in applied AI, so I can explain the trade-off to your non-technical stakeholder without a translator. How I like to start: send me your architecture, your failed outputs, or a handful of traces. I will tell you what to keep, what to fix first, and whether this needs a diagnostic, a scoped build, or nothing at all. I would rather talk you out of a bad build than sell you one. I work best with clients who have something live, real failure evidence, and someone on the team who can test the result.

I’m a UX/UI Designer with a background in visual design and illustration, focused on creating intuitive, visually engaging, and user-friendly digital experiences.

I’m a Senior UX/UI Designer with 6 years of experience designing complex web and mobile products, primarily in FinTech and B2B SaaS. Most of my background comes from long-term projects within design studios and as an in-house designer. I make UX decisions based on metrics, user feedback, and market benchmarks across multiple releases, focusing on real product outcomes rather than isolated visual concepts. This includes designing mobile apps for a top-tier U.S. bank with over 60 million users, complex crypto trading platforms (DEX & CEX), and scalable SaaS market-leading products. I previously worked at Clay, a design studio based in San Francisco, which has clients like Google, Slack, and Coinbase. I’ve also worked closely with startup teams, PMs, developers, and other stakeholders. I've led design processes end-to-end, from discovery and research to high-fidelity UI, design systems, and continuous product iteration based on real user feedback and business metrics My focus is on turning complex business and technical requirements into clear, user-friendly, and visually refined interfaces. How I help: • UX/UI Design for Web & Mobile products • Product UX for FinTech and B2B SaaS platforms • End-to-end design: research, flows, wireframes, and high-fidelity UI • Proficiency in Figma (scalable design systems built on components, auto-layouts, and variables) • UX grounded in accessibility standards and proven design patterns • Data-informed design based on analytics and user feedback • Strong foundations in visual hierarchy, typography, layout, and interaction design What makes my approach different: • I don’t treat design as decoration or task execution. My experience in studio and in-house environments trained me to think like an internal product team member, questioning requirements, aligning stakeholders, and designing solutions that scale over time. • My multidisciplinary background allows me to complement interfaces with motion, illustration, AI-generated visuals, and UX writing when it adds real value to the product. What ex-teammates say: “Ruslan showed high professionalism, autonomy, and strong responsibility for results. He excelled in FinTech UX/UI projects, met deadlines, conducted UX research, and was a proactive, collaborative team member.” 💬 Feel free to reach out if you’re looking for a designer who can go deep into your product, not just deliver screens.
