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. _________ Last updated: 15.05.2026

Your SaaS idea is ready. Your AI feature is on the roadmap. But shipping both with the right architecture, the right LLM choice, and a codebase that won't need a rewrite at scale, feels like a moving target. That's where I come in. I'm a full-stack developer who helps SaaS founders ship AI-powered MVPs and add intelligent features to existing products, without the rebuild later. 🌟 What I Actually Do: I integrate existing LLMs (GPT/OpenAI, Claude/Anthropic, AWS Bedrock, Gemini) into web apps and build SaaS infrastructure around them. I'm not here to ship a flashy demo and disappear. And I'm not here to train or fine-tune models from scratch, that's a different specialty. – AI integration into existing SaaS without rewrites – AI chatbots trained on your docs, websites, or internal data – Multi-tenant SaaS development from MVP to production – LLM-powered workflows: automation, content generation, smart assistants – Backend architecture, REST APIs, auth, billing, and deployment 🌟 Best Fit If: – You're shipping a SaaS MVP and AI is part of the value, but you're not sure which LLM, stack, or architecture to commit to – You have a SaaS in production and want to add AI features without breaking what already works – A previous dev bolted AI onto fragile architecture and you need someone to fix it cleanly – You care about long-term architecture, not just shipping the cheapest version – You want a developer who tells you when AI isn't the right answer for the job 🌟 Recent AI SaaS Work: – DocuChat - Multi-LLM chatbot SaaS supporting GPT, Claude, and Gemini, with vector search, multilingual support, and EU data residency. Stack: Nuxt + Node + AWS. – AddJuice - Multi-tenant lead-capture SaaS with an OpenAI-powered AI co-pilot. Stack: Next.js + Supabase. – FeedAI - Enterprise Laravel + AWS Bedrock build. Active enterprise contract with 169+ hours billed. 🌟 Tech Stack AI Integration: Claude (Anthropic), GPT (OpenAI), Gemini, AWS Bedrock Core Stack: Next.js, React, Laravel, TypeScript, Node.js, Vue.js, Nuxt.js, Tailwind CSS, Astro.js Infrastructure: Supabase, PostgreSQL, MySQL, AWS, Docker If your project fits any of the above, send me a brief about what you're building or the problem you're trying to solve. Within 4 hours during business days, I'll respond with a clear yes/no on fit and a rough timeline if we proceed.
