Over the last few years, my work has shifted strongly into AI‑assisted “vibe coding”—designing systems where you describe what you want in natural language, and AI + solid architecture does the heavy lifting. I combine classic engineering discipline with modern AI tools to turn plain‑language product vision into reliable, production‑ready software. 🔧 𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞 & 𝐃𝐨𝐦𝐚𝐢𝐧𝐬 I specialize in scalable, high‑performance web platforms and AI‑powered workflows for: Education & LMS Healthcare & automation Real‑time IoT & energy Media, streaming, and operations platforms 💡 𝐇𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐞𝐝 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬 SidioMS – Built engagement‑driven features and workflows to boost user adoption.

Most digital products lose users not because the idea is wrong, but because the interface makes them work too hard to get there. I'm a UX/UI Designer with 5+ years of commercial experience designing web and mobile products across SaaS, fintech, healthcare, e-commerce, and AI platforms, from early UX research and information architecture to high-fidelity Figma files ready for developer handoff. I've worked with international teams in Luxembourg, Switzerland, and Ukraine, delivering end-to-end design for startups and product companies. My process always starts before the first screen, understanding user behavior, mapping flows, and identifying friction before touching visual design. 🔍 What I bring to a project: - UX research: user interviews, competitor analysis, persona development, user flows, and information architecture - UI design: high-fidelity mockups, design systems with auto layout and variants, responsive layouts across desktop and mobile - Developer-ready Figma files: clean components, named layers, organized pages, so your team can build without guesswork - End-to-end ownership: from requirements and wireframes to prototype, usability testing, and handoff - Close collaboration with developers, PMs, QAs, and stakeholders throughout, not just at the start. 🎯 What I focus on: - Making complex flows feel simple and inevitable, SaaS dashboards, data-heavy platforms, multi-step mobile apps - Design decisions that hold up when developers start building, not just in Figma - Keeping visual structure consistent as the product grows, design systems, not just screens - Following platform guidelines (HIG, Material, Carbon) when they support clarity, adapting when they don't. 🤝 Who I work best with: Teams building products where clarity is non-negotiable, B2B SaaS, fintech platforms, healthcare apps, AI tools, and corporate websites where every screen needs to earn its place. 💬 Message me with your project, let's figure out if I'm the right fit.

AI Integration Engineer building production SaaS. Not demos. I ship live AI features - GPT/Claude integrations, RAG systems, AI-powered workflows - inside real products that customers pay for. 10+ years full-stack, Top Rated, 100% Job Success. My work currently powers platforms serving 10,000+ active users. Recent shipped products (live, in production): - BookBI: AI accounting app for UAE entrepreneurs, live on iOS + Android - FundsVisor: multi-tenant SaaS finance platform with AI receipt scanning - Nucleus AI: GPT + PubMed research tool for clinicians A few results clients hired me for: - Cut payment processing time by 40% by re-architecting Stripe/PayPal integrations for a SaaS platform - Built and shipped production LLM features (OpenAI and Claude APIs): chatbots, document processing, and AI-assisted workflows inside existing products - Migrated 2M+ records from legacy SQL Server to PostgreSQL with zero data loss and under 2 hours of downtime - Reduced regression testing time from 4 hours to 30 minutes with 500+ automated API tests (85% coverage) WHAT I DO BEST 1. AI integration into real products. I connect OpenAI/Claude APIs to your existing app with proper prompt design, streaming, cost controls, hallucination guards, and error handling - so the feature survives production traffic. 2. Full-stack SaaS product delivery. Next.js + TypeScript on the frontend, Node.js (Express/NestJS) or ASP.NET Core (.NET 6+) on the backend. REST and GraphQL, event-driven systems, WebSockets/SignalR. 3. Stripe billing done right. Subscriptions, webhooks, trials, marketplace payouts (Connect), multi-currency. I've shipped Stripe production twice - I write idempotent handlers and treat billing bugs as P0. 4. Cloud and DevOps. AWS (EC2, RDS, Lambda, S3, CloudWatch), Azure, Docker, CI/CD. 5. Databases and migrations. PostgreSQL, SQL Server, MySQL. Schema design, query optimization, high-stakes zero-downtime migrations. I also handle legacy modernization when clients need to move a monolithic or desktop system to a modern cloud stack, without breaking the business that depends on it. HOW I WORK I take ownership: I ask the questions that surface hidden requirements early, break work into clear milestones, write maintainable code with reviews and tests, and communicate proactively. You will never wonder what's happening with your project. Clients describe me as reliable, collaborative, and a clear communicator (their words, from endorsed reviews). A good fit looks like: a SaaS founder or team building AI features into a product, or one that needs a senior engineer who can think about the product, not just the ticket. I'm not the right fit for lowest-bid or rush-only projects. If you need AI capabilities added to your product, production Stripe billing, or a scalable backend built right the first time - send me an invite and let's talk through your project.
