Software Architect · Product Builder · Founder
I turn complex requirements into software that works in production.
I’m Alessandro De Stasio, founder of devFlorence and creator of Neurons. I combine more than 30 years of engineering experience with modern Java, AWS serverless architecture, product thinking, and hands-on delivery.

Florence, Italy · Building Neurons
Current focus
Two expressions of the same engineering practice.
One is how I work with organizations. The other is the product that proves the model under real architectural pressure.
The studio
devFlorence
Senior-led software development for dedicated applications, integrations, and reactive platforms shaped around real business processes.
- Architecture
- Modern Java
- AWS
- Direct collaboration
The product

Storytelling
UX, visual identity, technical diagrams, product website, and buyer-facing communication.
Engineering approach
Judgment is the layer that connects requirements, architecture, and code.
Tools and runtimes change. The difficult work remains understanding the problem, choosing the right boundaries, removing unnecessary scope, and staying accountable for what reaches production.
Business fit before abstraction
Model the process and its constraints before choosing patterns or platforms.
Architecture close to code
Technical direction remains grounded in implementation, tests, and operational reality.
Ownership end to end
Keep continuity from discovery and architecture through delivery and production.
AI-assisted, engineering-controlled
Use AI to accelerate exploration and execution without outsourcing judgment or accountability.
The devFlorence model
A lighter path from difficult requirements to working software.
devFlorence is the studio through which I work directly with organizations that need senior architecture and hands-on delivery without agency layers.
