I build B2B backend platforms, integrations, and cloud-ready workflows with Node.js, TypeScript, PostgreSQL, and AWS.
BrazilWhat I'm looking for
At Sellum, I own end-to-end engineering for a B2B platform spanning CRM, e-commerce, admin, WhatsApp, AI, and ERP integrations for 100+ users. I built the CRM as the sole hands-on engineer and delivered it in one-third of the planned time with one of the platform's lowest complaint rates.
I've also designed a marketplace for 10,000+ daily users at Ikatec and led a six-person team building ERP solutions at Fausoft. I work across Node.js, TypeScript, PostgreSQL, AWS, Docker, and React/Next.js, and I'm growing deeper in cloud architecture, infrastructure as code, containers, serverless, and observability.
