About Juan

I build scalable mobile applications and high-performance trading systems focused on real results.

With experience in algorithmic trading and app development, I help clients create automated solutions, MVPs, and production-ready systems.

I specialize in:
• Flutter mobile apps (Android & iOS)
• Backend development & API integration
• Trading bots (MT4 / MT5)
• Automation & data-driven systems

I focus on performance, scalability, and real-world usability — not just prototypes.

If you need a reliable developer who understands both technology and trading logic, I can help you build it.
