You will get a Senior Architecture Audit and Code Review for your backend
Project details
Transform your codebase into a scalable, maintainable, and production-ready system. I provide software architecture and code audits focused on performance, scalability, security, and maintainability. I review code quality, APIs, databases, architecture decisions, technical debt, and system bottlenecks. For AI-powered applications, I also assess LLM integrations, RAG pipelines, and production readiness. Deliverables include a detailed audit report, architecture recommendations, performance insights, security observations, risk assessment, and a prioritized action plan. Technologies include Java, Spring Boot, Node.js, TypeScript, Python, React, PostgreSQL, MySQL, MongoDB, Microservices, Cloud Architectures, and AI/RAG systems. My goal is to provid

About Jessica
Senior Backend Architect | Node.js & Java | AI & RAG Specialist
Rio de Janeiro, Brazil - 9:40 pm local time
My core expertise lies in designing resilient, scalable architectures using Node.js (NestJS) and Java (Spring Boot). I build systems that can handle massive concurrency, utilizing Domain-Driven Design (DDD), Event-Driven Architecture (RabbitMQ/Kafka), and advanced transactional patterns (like the Transactional Outbox Pattern) to ensure absolute data consistency and zero double-spending.
Beyond traditional engineering, I help businesses safely integrate Generative AI into their products. I specialize in building Retrieval-Augmented Generation (RAG) pipelines and autonomous AI agents, turning frontier models into secure, production-ready enterprise solutions.
HOW I WORK (The Asynchronous Approach):
To ensure the highest quality of code and deep focus, I work strictly on an asynchronous basis. I prefer clear, text-based communication via Upwork Chat, Jira, Trello, or GitHub Issues rather than live video meetings. You provide the problem and the requirements; I deliver clean, tested, and scalable code.
If you need a reliable architect to scale your backend or securely integrate AI into your platform, let's connect!
