Jonathan photo Open to Architect & Lead Opportunities

Hi, I'm Jonathan

Mobile Architect specialized in Agentic SDLC, scalable architecture, and AI-driven mobile engineering. With 7+ years of professional experience, I design and ship production-grade mobile applications using Flutter, SwiftUI, and Jetpack Compose. Based in Guatemala, collaborating with international teams in remote environments. As a lifelong learner, I pioneer Agentic SDLC—integrating autonomous agents (Cursor, n8n, GitHub) to automate the software lifecycle from coding to self-healing systems.
