Back to original languageAbout José Miguel
Need to launch an app or automate processes without losing months in development and extra costs?
I am a freelance consultant specializing in Flutter, automation (n8n), and applied AI, focused on reducing the delivery time and operational cost of digital products.
I don't just develop apps: I design complete solutions where product, business logic, and automation work together. The result is systems that are faster to build, easier to scale, and significantly more cost-efficient.
What I can do for your project
- Cross-platform app development with Flutter (iOS, Android, web, and desktop)
- Building MVPs in weeks, prioritizing validation and time-to-market
- Process automation with n8n (self-hosted or cloud)
- Integration of APIs, ERPs, CRMs, and databases
- Implementation of intelligent workflows and AI agents connected to real processes
- Architecture optimization to improve maintainability, scalability, and costs
My approach
I work with a clear mindset:
I combine mobile development with automation and AI to avoid oversized solutions and reduce manual dependencies from the start.
I have worked in demanding environments such as banking and retail, where reliability and efficiency are not optional.
If you are looking to build faster, with lower costs, and without compromising quality, let's talk.
