Quality Assurance Specialist & Customer Support | Detail-Oriented

I’m a Quality Assurance and Customer Support professional with extensive experience supporting global operations, improving processes, and ensuring consistent, high-quality results across multiple markets. I’ve worked in fast-paced, high-volume environments where accuracy, compliance, and customer experience are critical. As the main point of contact for international markets including Spain, Mexico, Brazil, and the United States, I supported QA performance, productivity, and operational consistency while collaborating closely with cross-functional stakeholders across different regions and cultures. My background includes leading and supporting teams, training and onboarding new hires, reviewing performance data, and providing clear, actionable feedback to improve quality and efficiency. I’m highly comfortable working with guidelines, audits, KPIs, and structured processes, and I take pride in delivering work that is precise, reliable, and on time. In addition to quality assurance, I have strong customer support experience. I’m confident handling escalations, resolving complex issues, and communicating clearly and professionally with customers, internal teams, and stakeholders from diverse cultural and professional backgrounds. I’ve been involved in process improvement initiatives that streamlined workflows, improved response times, and increased operational effectiveness. I work well independently, follow instructions closely, ask clarifying questions when needed, and communicate progress clearly. I’m comfortable working across time zones and adapting quickly to new tools and workflows. I also have a strong personal interest in financial markets, which I actively follow and trade independently. This has strengthened my analytical thinking, discipline, and comfort working with data, rules, and risk-based decision-making. I apply the same structured and methodical approach to my professional work, focusing on consistency and process rather than shortcuts. My background in marketing and communication supports clear, professional written and verbal communication, helping me contribute effectively to both customer-facing and operational tasks. I regularly support quality assurance and audits, content or process reviews, customer support via email, chat, or ticket systems, escalation handling, SOP and policy compliance, and operational or back-office support. I’m experienced with structured environments, performance metrics, and guideline-driven work, and I’m trusted with sensitive information. You can expect high attention to detail, clear communication, dependable follow-through, and a structured, improvement-focused mindset. I’m open to both project-based work and long-term collaboration, and I take ownership of my responsibilities from day one. If you’re looking for someone reliable who cares about quality, consistency, and getting things done right, I’d be happy to help.
