Demo profile

Tech Lead - Performance & Scalability Specialist

Córdoba, Argentina·10+ years·Spanish / English

Bio

I'm obsessed with making things fast. Started as a frontend dev 10 years ago but kept diving deeper into backend optimization, database tuning, and CDN strategies. Now I lead small teams to ship high-performance products. I write detailed post-mortems, love profiling tools, and believe documentation is a love letter to your future self. My stack centers around Next.js, PostgreSQL with proper indexing, and aggressive caching strategies.
