You will get a rest API in asp net core with clean architecture
Project details
You will get a production-ready REST API in ASP.NET Core (.NET 10), built with Clean Architecture and Domain-Driven Design — the same rigor used in production financial systems.
With 5+ years of full-stack experience, I bring proper software engineering practices to every API: clear separation between domain, application, and infrastructure layers, input validation with FluentValidation, and automated tests (xUnit, Moq) that actually verify the behavior — not just code that "works on my machine."
What sets this apart: I've built systems requiring idempotency and transactional consistency, where a duplicate request must never cause a duplicate transaction. That level of care carries over into every API I build, whether the domain is financial or not.
I care about getting the data model and requirements right before writing code, so expect a short scoping conversation before we start, to make sure the final API fits how your application actually needs to use it.

About Allan
Fullstack developer
Campinas, Brazil - 8:27 pm 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.
