Alejandro E.

I build mobile apps and SaaS products that are designed to make money, not just to ship. With 11 years in software engineering, I take a product from idea to launch and keep it growing: Flutter for iOS and Android, Next.js / React / Node.js / Firebase / Supabase for the web and backend, and Stripe for payments. Every feature is built with ROI in mind, shaped around the sales funnel and the end product. WHAT I DO BEST • Mobile apps with Flutter (iOS & Android), from architecture to store release • SaaS products with JavaScript / TypeScript frameworks • Measurement: customer acquisition and attribution with AppsFlyer, Meta, TikTok and Google Analytics, plus finding bottlenecks in the tech or in the marketing • AI automation and agent workflows that take repetitive work off your team WHY WORK WITH ME • Architecture background (Master's in Software Architecture): I build things that can scale • Strong attention to detail and clean, maintainable code • Based in Guatemala (CST): full US time zone overlap, no async delays • Native-level English and Spanish Software engineering has been my passion since I was 8 years old, and it shows in the work. Send me a message with what you want to build and I'll tell you how I would approach it.
