My guarantee covers 100% of the project development and 100% of the bugs found, with no time limit. * Hi there! I’m a software engineer with 12+ years of experience, focused on building scalable products and leading high-performing technical teams to solve real-world challenges with smart technology. - I’m currently: • Founder of Zavu.dev • Founder of Nely.ai • CTO and Co-founder at RendaloMaq, the largest construction equipment rental platform in LATAM. • Partner at TuMVP.com, helping founders rapidly validate and launch their MVPs with strong business and tech foundations. • Founder of Nely.ai, an AI-powered WhatsApp sales automation tool that helps companies sell 24/7 and scale customer engagement. - How do I manage so many projects at once? I lead a team of 10+ talented engineers, structured into squads that move fast and build with quality. Many of the products we’ve launched are self-sustaining SaaS platforms, generating steady revenue and running with minimal overhead. This setup allows me to keep doing what I love: building new products, validating ideas, and taking them to market quickly and effectively. Previously, I was Tech Lead at Cornershop (now part of Uber), and led the New Products Team at Talana, where I built full-stack solutions from the ground up. - What I can do for you: • Full-stack development (Python, Django, React, Next.js, PostgreSQL) • SaaS, automation, API integrations (Stripe, Twilio, WhatsApp), scraping • Scalable system architecture & performance tuning • MVP strategy, validation, and technical leadership Looking for someone who thinks like a founder, codes like a senior, and ships like a startup?
