About Bruno

Independent consultants and recruiters: transform your ideas into premium digital solutions, without wasting time.

Do you need a custom tool, a quick MVP, a client portal, or to automate your processes with AI, but you refuse the endless deadlines and the heaviness of traditional agencies.

As a Full-Stack Developer & AI Architect, I design high-fidelity web solutions for demanding professionals who want concrete results.

🛠 My Tech Stack (Ultra-fast & Scalable):
• Front-end: Lovable (Modern, premium, and fluid interfaces)
• Back-end: Supabase (Robust and secure architectures)
• Artificial Intelligence: Advanced integration (Claude Opus, Gemini)

⚙️ My Methodology (Focus on your efficiency):
Your time is your most valuable resource. My work process is designed to adapt to your busy schedule. I favor fluid, clear, and optimized communication (asynchronous exchanges, video demos/screencasts) to save you unnecessary meetings, while ensuring total transparency on project progress.

💡 Note: My current daily rate is an exclusive launch price for my first missions on Malt, in exchange for a detailed review at the end of the project.

Send me a message with the broad strokes of your project, and I'll immediately tell you how we can make it happen.
