For those operating in the software development industry, it's a known fact Software Houses have a pretty hard time communicating their unique selling proposition. Bravelab stands out from the crowd. They're not just a vendor - they're a technological partner that truly cares about their clients, their clients' business and they also care for one another as each team shall.

Frequently Asked Questions
Answers to the most common questions about my work process and services.
I specialize in AI development and consulting, focusing on building AI-powered products for the music and sports industries. My services include: AI solution architecture and implementation, custom AI tool development, prototyping and MVP creation, technical consulting for startups, and integration of AI capabilities into existing platforms. I work hands-on with clients from concept to delivery.
I follow a lean, iterative approach. It starts with understanding your problem and goals, followed by rapid prototyping to validate ideas quickly. I prefer working in short cycles with regular feedback loops rather than long planning phases. Communication is asynchronous when possible, with clear documentation. I focus on delivering working solutions fast, then iterating based on real-world feedback.
I work primarily with music industry companies (labels, distributors, artist management), sports tech startups, and organizations looking to integrate AI into their products. I'm particularly interested in projects at the intersection of AI, music, and sport. I work well with both technical and non-technical founders who have a clear vision and value hands-on collaboration.
