Hire the Best SQL Consultants

I help companies fix what's broken in their QA process and automate what's slowing them down. With 20+ years in software quality across banking, fintech, and retail (including major players like Transbank, Banco BCI, and Walmart Chile), I bring a rare combination: deep QA methodology expertise AND hands-on automation skills. WHAT I DO 🔹 QA Strategy & Process Consulting I audit existing QA processes, identify where bugs are slipping into production, and design testing strategies that actually scale with your team — not generic frameworks, but practical structures built around how your team really works. 🔹 Test Automation Selenium, Cucumber, JUnit, REST Assured — I build automated test suites that catch regressions before your clients do. I also leverage AI-assisted tools (GitHub Copilot) to accelerate test creation without sacrificing coverage. 🔹 n8n Workflow Automation & Data Migration I design and implement n8n workflows for complex business process automation and large-scale data migrations. Recent project: led a complete Odoo v12 → v16 CRM migration, building n8n workflows that analyzed, deduplicated, and validated over 1,000,000 contact records down to 370,000 clean, verified entries — a process that would have been unmanageable manually. WHY WORK WITH ME - ISTQB Foundation, SAFe 5 Agilist, Scrum Manager, and DevOps Fundamentals certified - 20+ years of hands-on QA leadership, not just theory - I communicate clearly, document everything, and don't oversell — if something isn't a good fit for your situation, I'll tell you - Comfortable working independently with minimal oversight, async-friendly, clear weekly reporting Let's talk about what's slowing your QA process down — or what manual process is eating your team's time that could be automated.
