I am Raphael, a Full Stack and AI Software Developer with more than 6 years of experience building SaaS, enterprise platforms and AI-native products.

I recently worked as a Founding Engineer at BuilderBase, where I owned core parts of the codebase, engineering processes and product architecture from pre-seed through a €500K+ funding round. Before that, I worked at a US fintech (SixPoint Capital) contributing to AI-driven underwriting workflows, modular SaaS architecture, scalable APIs and agentic systems for private credit and structured finance. I also bring strong experience working in fast-growing startup environments and I am a founder myself, which gave me a broader product vision and direct experience in product decision making.

I have a graduation in Software Engineering area and I'm currently pursuing an MBA in Big Data. I'm also Certified Oracle AI Foundations Associate, JavaScript/TypeScript Platform Developer and on track for the AWS Solutions Architect - Associate.

I am currently looking for a full time remote role where I can keep working with modern TypeScript, Python backend APIs, scalable SaaS architecture and AI/ML integrations. True team player and committed to delivering results from the very first days. 0-1 specialist, high product vision and high ownership + clean communication working-style.
