Gley Müller
@gleymuller
I lead mobile and enterprise IT teams to deliver reliable data-driven solutions.
BrazilWhat I'm looking for
I bring 20+ years of Information Technology experience, combining systems analysis, software development, database administration, ERP/CRM support, and business process mapping. I’m at my best translating business needs into functional and technical requirements that keep operations running smoothly.
I focus on SQL data analysis, validation, troubleshooting, reporting, and system integrations that depend on consistent data and cross-system communication. I work closely with stakeholders and technical teams to analyze requirements, document processes, resolve issues, and support stable, scalable delivery.
Most recently, I’ve led mobile development as a Tech Lead—using Swift, Flutter, and C#—building BLE-connected solutions integrated with proprietary devices. I’ve also managed Zoho CRM and supported multilingual, SEO-focused web experiences, while continuing to drive automation with AI agents and chatbots.
