About me

I'm a Product Engineer with 11+ years of experience building SaaS platforms, fintech products, AI-powered workflows, and developer-facing tools.

Throughout my career I've worked across startups, funded ventures, scale-ups, and global technology companies. I've repeatedly joined organizations during critical growth phases, helping establish engineering foundations, design scalable architectures, and deliver products that solve complex business problems.

My experience spans frontend, backend, platform engineering, design systems, developer experience, and AI applications. I've built products from zero to market, led large-scale migrations, designed configurable platforms, and worked directly with founders, executives, investors, designers, and customers.

Some highlights:

• Founding Engineer at EleveCRM and MarinaClub
• Built AI-powered CRM workflows using Amazon Bedrock
• Designed scalable Custom Fields platforms and integration architectures
• Created Design Systems used across engineering organizations
• Worked on digital banking products at Conta Azul
• Helped improve Remote.com's website performance by ~95% and reduce load times by ~6x

I enjoy turning complex technical systems into simple and intuitive user experiences.
