Looking to grow your sales, enter new markets, or build a stronger outbound sales process? I combine engineering knowledge with over 10 years of sales and business development experience, helping companies generate opportunities, build partnerships, and close business across multiple industries and international markets. Before earning my Mechanical Engineering degree, I worked in technical sales for Parker and Bosch Rexroth distributors in Brazil, helping industrial clients select hydraulic and pneumatic solutions, analyze competitor products, identify technical equivalents, and develop hydraulic power unit projects. This experience taught me how to combine technical expertise with commercial strategy. For the past several years, I've worked with international companies from China, North America, Europe, and Latin America, supporting business development, market expansion, lead generation, appointment setting, technical sales, and client acquisition efforts. My experience includes: ✔ Cold Calling & Appointment Setting ✔ SDR / BDR Activities ✔ Business Development ✔ Technical Sales ✔ Lead Generation & Prospecting ✔ CRM Management & Pipeline Development ✔ Sales Presentations & Discovery Calls ✔ Partnership Development ✔ Market Research & Market Validation ✔ Outreach Campaigns (Phone, Email & Social Selling) One of my most interesting projects involved helping importers understand and adopt trade credit solutions backed by Sinosure, a Chinese state-owned insurance company. Through this structure, Sinosure can approve a credit limit for an importer, allowing Chinese suppliers to offer deferred payment terms on part of the shipment value, often extending payment up to 120 days after shipment. This creates a significant cash flow advantage for importers, allowing them to preserve working capital, increase purchasing volume, and expand their business without tying up as much capital upfront. Most companies had never heard of this solution before, so my role involved educating prospects, building trust, explaining how the structure worked, handling objections, and helping them understand how it could support the growth of their business while also benefiting their Chinese suppliers through larger and more frequent orders. Industries I've worked with include: • Industrial Equipment • Hydraulics & Pneumatics • Manufacturing • Valves & Industrial Components • PCB / PCBA Manufacturing • International Trade • Consulting Services • SaaS & Technology • Logistics & Supply Chain • Market Expansion Projects Why clients hire me: ✔ Mechanical Engineer with active professional registration ✔ Electromechanical Technician background ✔ Technical and commercial experience ✔ Fluent English ✔ Fluent Spanish ✔ Native Portuguese ✔ Comfortable speaking with business owners, executives, engineers, buyers, and procurement teams ✔ Proven ability to explain and sell complex solutions ✔ Strong experience in outbound sales and relationship building ✔ Ability to learn new products and industries quickly Additional expertise: ✔ Brazil & LATAM Market Entry ✔ International Supplier & Partner Development ✔ Chinese Supplier Communication ✔ Cross-border Business Development ✔ Local support for international companies expanding into Brazil Whether you need a sales representative, SDR, business development specialist, technical sales professional, appointment setter, or a trusted partner to help grow your business, I'd be happy to discuss how I can contribute to your sales and expansion goals.
