You will get Backend & API Development (Java / Spring Boot)
Project details
Elevate your software with a high-performance, enterprise-grade backend powered by **Java and Spring Boot**. As a Senior Backend Engineer specializing in Full Cycle Architecture, I build secure, scalable, and maintainable systems designed to grow with your business.
Choose the tier that matches your project scope:
• **Starter ($149):** Perfect for MVPs. Delivers up to 3 REST endpoints, essential CRUD operations, standard DB integration (PostgreSQL/MySQL), and OpenAPI/Swagger documentation.
• **Core Backend ($349):** Built for growing apps. Includes up to 10 endpoints, secure JWT authentication, robust business logic, and automated unit testing for reliability.
• **Enterprise Architecture ($3,499):** A production-ready, Full Cycle solution. Features complex microservices, Redis caching, third-party API integrations, advanced security, and complete Docker containerization.
**The Development Standard:**
Every project follows a strict lifecycle: Architecture Design, Secure Implementation, Automated Testing, and a complete Code Handover. I ensure your backend is not just functional, but built on industry best practices.
Let’s build a technical foundation your application can rely on.

About Gabriel
Senior Backend Software Engineer | Java & Spring Boot | AWS
Barra do Garcas, Brazil - 3:43 pm local time
I am a Senior Backend Software Engineer with over 6 years of experience building scalable, secure, and high‑performance solutions. I primarily work with Java and Spring Boot, focusing on the design, implementation, and evolution of robust APIs, with a strong emphasis on code quality, performance, and maintainability.
I have solid experience in backend architecture, system integrations, automated testing (unit and integration), and software engineering best practices, applying architectural principles to deliver resilient and well‑structured systems. I also work extensively with AWS cloud services, including DynamoDB, S3, API Gateway, Glue, Athena, Firehose, and Secrets Manager, as well as infrastructure as code (Terraform) and CI/CD pipelines.
I have a strong background in observability, reliability, and performance, with hands‑on experience building metrics, logs, and dashboards using Datadog, analyzing bottlenecks, and continuously improving production systems. I work collaboratively, actively contributing to code reviews, technical documentation, and architectural discussions.
Currently, I work as a Senior Backend Engineer at Zup Innovation, allocated to Itaú Unibanco, contributing to mission‑critical financial solutions related to proposals, credit, and limit approval. I am currently pursuing a Postgraduate Degree in Full Cycle Architecture, focusing on advancing my skills in software architecture, distributed systems, and business‑driven architectural decision‑making.
