Acerca de Saul
I help companies build and scale backend systems using AWS serverless architecture and automation tools like Make.com and n8n. With over 10 years of experience as a tech lead and backend specialist, I’ve designed microservice infrastructures using CDK, Lambda, DynamoDB, Step Functions and more. I specialize in automating business processes, integrating third-party APIs (Zendesk, Stripe, Klaviyo, booking systems), and implementing AI-powered workflows using AWS Bedrock and GPT APIs. My goal is always to reduce operational complexity and deliver measurable value. I'm available for freelance projects, MVP launches, or backend consulting.
