Jeferson Amorim

I am a senior full-stack software engineer passionate about creating exceptional user experiences and building scalable, cutting-edge web systems. I combine deep frontend expertise in JavaScript frameworks with strong backend skills in Node.js, PHP, and C#.

I've led end-to-end projects from MVP to production, designing resilient event-driven architectures and maximizing cloud value using AWS services like ECS Fargate, CDK, Amplify, DynamoDB, SQS, S3, Cognito, RDS, and CloudWatch. Notable outcomes include building an AI-first customer service platform and achieving zero message loss in event processing.

I leverage Large Language Models to improve UX through natural-language interfaces and have expanded into neural networks, delivering ML solutions such as MLP+LSTM models with strong market prediction performance and efficient training strategies. I also drive migration and modernization efforts—TypeScript conversions, zero-downtime cloud migrations, and CI/CD automation.

Proactive and self-motivated, I mentor junior engineers, enforce documentation and testing standards, and prioritize accessibility, privacy (GDPR), and cost-effective architectures to help startups and small businesses turn ideas into production-ready systems.
