Senior Product Designer | SaaS & Enterprise UX · Workflow Redesign · Business-Driven Results Most designers deliver screens. I deliver outcomes. In 8+ years designing enterprise and SaaS products, I've helped teams generate R$3M+ in additional revenue through a single product page redesign, reduce churn by 22%, cut onboarding time by 40%, and build design systems adopted across 5 product lines — all while navigating the real constraints: regulated environments, legacy systems, cross-functional politics, and the pressure to ship. I've worked with companies in Brazil, Australia, and the US across telecom, e-commerce, fintech, and B2B SaaS — including Brazil's largest telecom provider, where I was design lead for the e-commerce team responsible for 31% of company revenue. What makes me different: I sit at the intersection of design, product strategy, and business. I've presented to C-level, partnered with PMs to shape roadmaps, led AI/ML product ownership, and collaborated daily with dev leads and technical stakeholders. I don't need hand-holding — I need context, and I'll take it from there. I work best with teams that: — Have complex workflows, enterprise constraints, or regulated environments — Are dealing with friction, churn, or low adoption and need a clear diagnosis — Want design that's technically feasible, not just visually polished — Need someone who communicates clearly across business, design, and engineering What you can expect: Figma deliverables that developers can actually build. Research that informs decisions, not just validates them. A designer who understands that a beautiful product that doesn't convert is just an expensive prototype. Available for fixed-scope projects and long-term partnerships.

Hi, I’m Saimon. I design systems and products that must work in the real world, under load, vibration, corrosion, pressure, heat, and continuous operation. Not just clean CAD models, but solutions that can be built, tested, and used in production. I’m new to Upwork, but I bring 20+ years of experience in R&D from industrial solutions and product design. 🔹 What I do • Mechanical design, from concept to CAD to production-ready • Product development and design improvement • Design for Manufacturing, DFM, and cost optimization • Structural, thermal, and vibration analysis, FEA • Engineering calculations and validation • Prototyping and real-world testing support • Electromechanical integration, mechanical + PCB + sensors Tools: SolidWorks | Fusion 360 | AutoCAD | Abaqus 🔹 What I deliver • Enclosures for electronics, 3D printed or injection-molded • Structural and sheet metal designs, fabrication-ready • Industrial machinery components and assemblies • Internal mechanisms, motion, guidance, interaction • Production-ready CAD + 2D drawings, GD&T and tolerances • DFM-optimized parts and assemblies • Thermal-aware designs, heat dissipation and airflow • Sealing systems, IP-rated and outdoor applications 🔹 Additional capability • Engineering data analysis using Excel and Python • Performance evaluation and system optimization • Basic predictive models for engineering applications • Design automation, CAD workflows and repetitive task reduction 🔹 How I approach projects I don’t start with CAD. I start with: • How the system will actually be used • Where it can fail • How loads and forces move through the design Then I build the solution around that. 🔹 Getting started Since I’m building my presence on Upwork, I’m open to starting with a small initial phase. This allows you to evaluate my work, speed, communication, and quality, before moving forward with a larger scope. 🔹 If you need to • Fix a design that isn’t working • Turn an idea into something manufacturable • Develop a prototype that performs in real conditions Let’s talk. ✉️ Send me a message, I’ll review your project and suggest the best way forward.
