Senior Full Stack Engineer & Tech Lead with 10+ years in tech. I build fast, scalable, high-quality web and mobile products, integrating backend, frontend, mobile and AI in a single workflow.

My background combines a solid foundation in automation, tooling and infrastructure (INVAP, Argentina's national Digital TV project) with recent experience as Frontend Tech Lead at GoJiraf, leading a team of up to 8 people and working with clients like MercadoLibre and Samsung. Today I build my own products with real users: TuMenu with 30+ active restaurants, Ascend Life with paying users since launch, Pixora open source with local AI, and more.

That combination allows me to understand the whole system and make better architectural, performance and scalability decisions.

Available 100% remote for Senior Full Stack / Tech Lead / Engineering Manager roles and for technical product consulting with AI.
