What I'm looking for

I'm looking to apply my full-stack, data, AI, and machine-learning knowledge to build scalable solutions that transform education at scale.

I've built and maintained financial products at Grupo Presença, including AGS Finance, Cena Invest, and Zenith Capital. I delivered critical workflows for contracts, payments, dividends, withdrawals, and liquidity using NestJS, Next.js, TypeScript, and Node.js.

I independently developed a production multi-tenant GRC platform with around 15 integrated modules for risks, audits, controls, action plans, documents, Kanban, calendars, and automated reminders. I designed granular RBAC and audit trails, and migrated its infrastructure from Supabase to SQL Server with JWT authentication.

I've also published more than 30 interactive Power BI dashboards and built real-time commercial performance dashboards, geospatial visualizations, gamification, and Kanban tools. I'm looking to apply my full-stack and data skills to AI and machine-learning solutions that transform education at scale.
