I design and optimize high-performing websites and digital experiences with a strong focus on conversion, usability, and business goals.
Most of my work involves designing websites from scratch - from UX strategy and wireframes to final UI, implementation, and ongoing optimization. I work with businesses that need more than just a visually polished website. My focus is on creating clear user journeys, reducing friction, improving conversion rates, and building experiences designed around measurable outcomes.
What makes my approach different is the combination of UX design, CRO thinking, behavioral analysis, and hands-on implementation experience. I don’t make design decisions based on assumptions or visual trends alone. My work is informed by real user behavior, analytics, heatmaps, session recordings, and conversion data to understand where users struggle, where they drop off, and what prevents action.
I’m especially effective on:
• High-converting websites built from scratch
• Website redesigns focused on UX and conversion improvements
• Landing pages and funnel optimization
• UX optimization for existing websites and digital products
• End-to-end projects (strategy → wireframes → UI → implementation)
• WordPress / Elementor websites with custom UX thinking
• SaaS and digital product interfaces with complex user flows
My process:
1. Behavioral Analysis & UX Audit
I begin by analyzing user behavior patterns, heatmaps, session recordings, analytics data, and conversion bottlenecks to identify friction points and weak areas in the user journey.
2. UX Structure & Wireframes
Once key problems and opportunities are identified, I restructure user flows, improve content hierarchy, simplify decision paths, and create wireframes focused on usability and conversion performance.
3. UI Design & Implementation
After validating the structure, I design scalable, conversion-focused interfaces and support implementation in WordPress / Elementor to ensure the final product matches both the UX strategy and business goals.
4. Optimization & Iteration
I treat optimization as an ongoing iterative process rather than a one-time redesign. After launch, I continue analyzing user behavior, engagement patterns, and conversion performance to refine the experience based on real-world usage and measurable data.
Because I also understand the implementation side of the process, I’m able to bridge the gap between design and development and avoid many of the UX compromises that typically happen during handoff.
Over the years, I’ve worked across websites, eCommerce, CRO projects, and digital products, helping businesses improve usability, increase conversions, and create more effective online experiences.
Core areas of expertise:
• UI/UX Design
• Conversion Rate Optimization (CRO)
• User Behavior Analysis
• Wireframing & UX Strategy
• Website Redesigns

Since 2003, I've helped companies improve digital products by making them easier to understand, easier to use, and more effective for their business.
Today my work focuses on UX Audits, Customer Journey Analysis, usability improvements, onboarding optimization, and identifying product friction that prevents users from reaching value.
I investigate how a product actually works from a customer's perspective, from the first landing page visit to onboarding, activation, and conversion. My goal is to identify where users become confused, lose trust, abandon the journey, or fail to complete key actions, then provide clear, prioritized recommendations that your team can implement.
My audits typically cover:
• Landing pages & messaging
• Sign-up & onboarding flows
• Customer journeys & user flows
• Navigation & information architecture
• Forms, dashboards & operational workflows
• Mobile & desktop usability
• Product friction & conversion barriers
Recent experience includes improving SaaS, healthcare, transportation, and enterprise products.
Route One Group (Transportation SaaS)
Product Design Lead responsible for operational UX across a fleet management ecosystem used by 10,000+ commercial drivers. Designed workflows for ELD compliance, driver onboarding, fleet operations, billing, and dispatch, helping simplify complex business processes and reduce compliance violations by approximately 40%.
Omio (Independent UX Audit)
Conducted an independent UX audit of Omio. Produced a 10-page investigation report with annotated mockups, structured around Problem → Impact → Recommendation. Identified UX, visual, navigation, and journey friction issues with prioritized improvements.
Sizov Report (B2B Analytics Platform)
Investigated the trial request and onboarding journey for an institutional market intelligence platform. Redesigned qualification, email verification, and activation flows to reduce friction while preserving lead qualification and business control.
Aesthetic Record
Redesigned appointment scheduling and operational workflows for a healthcare platform. Simplified complex multi-step interactions and reduced booking time by approximately 50%.
MedNote
Designed onboarding and information architecture for a healthcare application managing family medical records. Created multiple user paths for different use cases while reducing cognitive load during first-time use.
If you're getting traffic but users aren't activating, converting, or completing key actions, I'll help identify what's slowing them down and provide practical recommendations focused on business impact, not just design opinions.

B2B SaaS products get complex faster than their UX can keep up. Dashboards become overloaded. Workflows mirror backend logic instead of user behavior. Role-based systems confuse users instead of guiding them. AI-era chaos make the product hard to use.
I help B2B SaaS teams — from early-stage startups to scaling platforms — restructure complex workflows, simplify dashboards, and turn overloaded products into scalable systems. Through UX architecture and AI-accelerated delivery, not just visual UI design.
My core work:
• B2B SaaS dashboards and admin panels (data-heavy, multi-role, decision-centric)
• Complex workflow systems, onboarding flows, and permission-based navigation
• Figma design systems built for scale — components, tokens, auto-layout, dev handoff
• AI product UX — structuring AI-powered platforms and AI-native SaaS into usable, scalable products
• Early-stage SaaS: rapid UX architecture for founders moving from MVP to market-ready product
• Information architecture for CRM, ERP, FinTech, RegTech, healthcare, and operations platforms
How I work:
• Start with UX audit and information architecture — before touching screens
• Wireframes → high-fidelity Figma → interactive prototype → developer-ready handoff
• Design system extraction: if you have a chaotic Figma file, I turn it into a scalable, documented system
• AI-accelerated delivery: architecture sprints completed 2–3x faster than traditional agency timelines
• Async-first, milestone-based — clear reviews, no guesswork
What clients say and see:
• Top Rated Plus | 100% Job Success Score | 112+ completed contracts
• FinTech, RegTech, healthcare, AI platforms, real estate, cybersecurity, ERP/operations software
• Served early-stage startups (pre-seed to Series A) through to scaling B2B platforms
• Clients use words like: "restructured the entire product flow", "finally made sense of our admin panel", "shipped faster after the design system was in place"
• 200+ UX/UI and product design engagements delivered across complex B2B SaaS and data-heavy platforms as the founder of LeverageUX.
• 175+ millions raised by founders with our design assistance
• Our work helped founders to win deals with brands like Microsoft, Tesla, BMW, DHL and Visa, etc.
If your SaaS product feels powerful but hard to use — send me:
• A screenshot or Loom of the problem area
• What your users are confused about or where they drop off
• What "done" looks like for this engagement
I will tell you within 24 hours whether it's a quick fix or a structural problem — and what the right approach is.
