Introduction
Product leader with 15+ years of experience building SaaS and mobile products from zero to one, primarily in digital health. I combine technical depth with product intuition to lead cross-functional teams, ship secure and compliant experiences, and scale impact in regulated environments. I founded a healthcare app company that reached 150K+ downloads and a 4.8 rating, and later worked as Product Manager at Docline, defining the roadmap for telemedicine platforms including video consultations, e-prescriptions, and patient management tools. I've navigated data protection, interoperability, and clinical validation challenges while aligning user experience with business goals. As a consultant and advisor, I've helped leadership teams refine product strategy, discovery practices, and processes, bridging medical, business, and engineering perspectives. Technically fluent, I work hands-on with software architectures, Flutter/Android, and AI/LLMs, prototyping agents, automations, and data pipelines to turn ideas into working software fast. I've also taught at MIT Horizon and Alebat Education, leading sessions on AI in healthcare and digital transformation, helping professionals bridge clinical practice with emerging technologies.

Buildink aimed to close the gap between non-technical individuals and developers by providing an orchestrator of agents that acts as Product Managers that ease the discovery process for ideators and generated a PRD document that developers could use in minutes. I built the MVP using Flutter for the front end and Firebase to shorten the time to production. The architecture leverages a set of custom-made agents that connect to an LLM service like OpenAI API but are open to other services due to the possibilities offered by Langchain. Tech used: - Flutter - OpenAI API - Custom-made architecture of Agents - LangChain - Firebase * The links may show newer information since the project is evolving through other co-founders.

I help tech companies to find the best candidate that fits their positions. When looking for a high skilled engineer, with either a hardware or a software profile, HHRR consulting firms usually fail getting the best candidate due to the lack of technical understanding and deep needs of the client. If you are looking for a candidate I can help you to find a better fit than a typical agency, just contact me!
