# João Pedro Batista da Silva > Portfolio of João Pedro Batista da Silva — backend-focused fullstack developer in Recife, Pernambuco, Brazil. Java, Spring Boot, Python, FastAPI, React and TypeScript. 4x AWS certified. I'm a self-taught, backend-focused fullstack developer from Recife, Brazil. I build RESTful APIs with Spring Boot, Flask and FastAPI following clean architecture, and ship features end-to-end with React, TypeScript, Express and Supabase. My background spans C, Java and Python, with hands-on work in automation, messaging (RabbitMQ) and data pipelines. ## About I'm a backend-focused fullstack developer from Recife, Brazil — self-taught, and most at home on the server side. Most of what I build lives behind the API: REST services, automation, messaging and data pipelines, with just enough frontend to ship the whole thing end to end. Currently building software at Web Star Studio and finishing my B.Sc. in Computer Science at CESAR School. I'm 4x AWS certified, Red Hat certified, and I enjoy turning messy problems into clean, well-tested systems. ## Skills ### Backend & Data Java · Spring Boot · Python · FastAPI · Flask · C · REST APIs · Clean Architecture · JPA · JWT · RabbitMQ · MySQL · PostgreSQL · SQL · Power BI ### Frontend & Web React · TypeScript · JavaScript · Node.js · Express · Supabase · HTML / CSS ### DevOps & Cloud Docker · Linux · AWS · Git · Selenium ## Certifications 8 verifiable credentials, including 4 from AWS and one from Red Hat.
