Leonel R.

I help early-stage startups move fast — from zero to a working product, without wasting time on the wrong architecture or the wrong team. With 6+ years as CTO & Co-Founder at Vita Wallet (a fintech operating across Latin America), I've built and scaled engineering teams, designed backend systems handling real financial transactions, and led the full technical strategy from day one. What I bring to your startup: → MVP & Go-to-Market: I know how to ship fast without breaking things later. I'll define your architecture, choose your stack, and make sure your first version is built to scale. → AI Automation: I implement practical AI solutions — Claude Code agents, custom chatbots, workflow automation with n8n and Make. Not experiments. Things that actually save your team hours every week. → Tech Strategy: I translate complex technical decisions into business language. If you're a non-technical founder, I'll be the person who tells you the truth about what's feasible, what's not, and what order to build things in. → Team & Process: Agile methodologies, hiring guidance, and engineering culture — I've built teams from scratch and know what good looks like at each stage. Previously: Backend engineer at Avenida+ (ecommerce, Ruby on Rails, AWS) and Upsidecorp GmbH. Wayra startup accelerator winner (2014). I work in UTC-3 (Buenos Aires), with solid overlap for US and European clients. Let's talk about your project.
