You will get a production-ready serverless API on AWS Lambda (Node.js)

Project details
You will get a production-ready serverless REST API on AWS, built with Node.js and TypeScript — designed to scale automatically and cost less to run than traditional servers.
With 5+ years of full-stack experience, I bring proper software engineering practices to serverless architecture: clean code, documented architecture decisions (ADRs), and Infrastructure as Code — not just a Lambda function that works, but one that's maintainable and production-grade.
What sets this apart: I've built and shipped serverless systems handling real production workloads, including asynchronous processing pipelines and secure file handling with presigned URLs. Every architectural choice — HTTP API vs REST API, DynamoDB vs relational, event-driven vs synchronous — is made deliberately, not by default.
I care about getting the requirements right before writing code, so expect a short scoping conversation before we start, ensuring the final API actually fits how your application will use it.

About Allan
Fullstack developer
Campinas, Brazil - 12:31 am local time
On the backend, I design APIs, event-driven workflows, and serverless architectures using Lambda, API Gateway, DynamoDB, and S3. I care deeply about reliability — idempotency, transactional consistency, and clean architectural boundaries are recurring themes in my work.
On the frontend, I've shipped React applications at scale — including a Web3 lootbox platform with 140k+ users and 6M+ interactions, where I reduced bundle size by 70%+ through esbuild, manual chunking, and CDN optimization.
I also work with .NET when the stack calls for it, and have experience with Flutter for mobile.
Open to remote opportunities in Brazil and internationally.
