Senior QA Engineer

I'm a 34-year-old Argentine QA Automation from Córdoba, passionate about building unbreakable backend systems and mentoring teams to ship with confidence. With 6+ years in QA (4 as Lead), I've led automation strategies for mission-critical telco platforms at Claro Argentina, where I designed Java-based frameworks from scratch using Serenity BDD, Playwright, RestAssured, and Cucumber. Beyond APIs and CI/CD pipelines (Jenkins), I've audited smart contracts on EVM chains (Ethereum, BSC, Polygon) with Foundry, Slither, Hardhat, and Tenderly. From full-stack dev at Piacentini Seguros (migrating legacy systems to Google Cloud SQL, cutting response times 50%) to teaching Algorithms/Data Structures at UTN for 500+ students, I thrive turning "testing bottlenecks" into superpowers. I'm the guy who debugs flaky tests at 7 PM, pairs with devs on war-rooms, and celebrates when coverage hits 95%. Seeking Senior QA Automation, SDET, Test Lead, or Blockchain QA roles in nearshore LATAM/USA—remote, UTC-3, immediate start (48 hs). Dual Argentine-Italian citizen (full EU authorization). Let's connect if you're scaling teams with robust tests! 🚀
