I’m Rafael.
Nice to meet you.
I’m a Product Owner who builds his own products end to end, solo, with AI agents: from talking to the people who run the operation to a system running in production. Before that came field sales, retail and market intelligence, which is where my business sense comes from.
I like understanding the work of the people who reach out to me. What takes time, what causes problems and what we can improve.

From problem to product in production
I’m the PO and the builder at the same time. Solo, with AI agents, I take an idea from a conversation with the people who run the operation to a product in production, and I own the outcome.
Discovery on the shop floor
Six years of POS, inventory and stockouts at Heineken, plus market intelligence with CRM and Power BI. I talk to users before defining any requirement.
Backlog and prioritisation
I decide what goes in, what stays out and in which order, based on operational impact. I ship in short cycles and adjust with user feedback, without over-engineering.
Building with AI agents
AI agents act as my engineering team: data modelling, code and deployment. Every delivery goes through my review and my decision.
Approvals and operations
MiseOn verified by Meta as a Technology Provider (WhatsApp Business API) and approved on iFood. Multi-tenant products with row-level access and audit trails.

I’m Rafael Maldivas, developer and founder of Maldivas Tech. My background includes sales, quality and processes, woodworking, technical training in chemistry and gastronomy. These experiences shape how I understand a business.
Today I bring that experience to software development, integrations, data analysis and digital services. I enjoy following a project from the first conversation through to everyday use and improvements based on feedback.
Maldivas Tech is my registered company, with contracts and service invoicing. I take on consulting and development projects and am also open to opportunities working with a team.
