Hi, I'm Leonardo, an Expert-Vetted Designer on Upwork (top 1%) and certified Framer Pro. With 20+ years of experience, including work at IBM and Accenture serving Fortune 500 clients, I have helped founders and growing businesses turn their websites into their best-performing sales asset, combining sharp design with conversion rate optimization, UX strategy, and behavioral data.

What I deliver: ✅ Web Design & Development: Claude Code, Lovable, Cursor, Figma, Framer (Certified Pro), Webflow, WordPress (Elementor, Thrive, Divi, Avada, Beaver, Woocommerce) ✅ Landing Page Design & Optimization: built to convert, not just to impress ✅ UX/UI Design: user flows, wireframes, and interfaces built around real behavior ✅ CRO Audits & Strategy: find conversion leaks and prioritize high-impact fixes ✅ Performance & Core Web Vitals: speed and stability that support conversion ✅ A/B Testing & Growth Strategy: data-driven iteration, not guesswork I also work AI-native, using the latest AI tools across my workflow to deliver faster and more cost-effectively, without ever sacrificing strategic depth or quality. ⭐ What some of my 1,000+ clients say: "5 stars all across the board. Leonardo and his team are pros in every regard. Attention to detail, creativity, execution, communication, revisions, getting it done on time. Everything. Will 100% hire again." "Leo understood the overall goals for the site and brought a clear creative and development approach aligned with both budget and business needs… working with Leo was a professional and pleasant experience that exceeded my expectations." "His focus on outcomes and quality is exemplary." "Leonardo had a great consultative approach… he delivered a website that exceeded all expectations." ⚡ For larger or multi-phase projects, I lead Thinknova, my Top Rated agency of expert designers and developers ready to scale with you. 📅 Let's talk.

If you need a custom app built from scratch — or you’re stuck with a half-finished codebase from a previous developer — I can help you move it forward without unnecessary rewrites. I’m Adrian, founder of Peer Concept, a small software development team. Clients work directly with me, and I bring in my team when the project needs extra frontend, backend, DevOps, QA, or UI/UX capacity. Most of our work comes from two situations: - founders building a product from zero - teams stuck with an unfinished or messy app that needs to move forward What we build and fix: - custom web applications using React, Next.js, Angular, Node.js, Django, FastAPI, and .NET - mobile apps with React Native - REST APIs and third-party integrations: payments, CRMs, internal tools, external platforms - AI features using OpenAI, Claude, LLM APIs, automation workflows, and custom AI tools - existing app takeovers — we read the code, understand the system, and continue development - end-to-end delivery: scope → build → deploy → maintain Relevant examples: - AuctionForecast — took over a data-heavy wine auction platform after multiple developers and continued development without a rewrite - Firefly — built an AI compliance monitoring system that analyzes customer communications and risk signals - DrForms — developed an AI medical documentation app that turns doctor-patient audio into structured reports - MyKidsTales — built an AI storytelling platform with personalized story generation - Blue Mountain Loans — built a consumer lending platform with application, e-signature, direct deposit, payment-processing, and risk-scoring API integrations Recent client feedback: “Adrian did a great job on our loan platform. We had multiple API integrations and a complex flow, and he handled everything smoothly.” We don’t take every project. But when we do, we focus on clear communication, stable delivery, and shipping working software. Send me a short description of what you’re building or trying to fix, and I’ll tell you within 24 hours if we’re a good fit.
