I will build currency converter api with live rates
Lucas Aguilera
About this gig
I build secure REST APIs that fetch and track real-time currency exchange rates for your business or app.
Built on ASP.NET Core (C#) with JWT authentication and Entity Framework Core, the API connects to a live exchange rate source and returns accurate, up-to-date conversion data between any two currencies (USD to ARS, EUR to USD, etc.), with full request history stored in your database.
What I offer:
- Real-time currency exchange rate lookup between any two currencies
- JWT-secured REST API backend
- Exchange rate history/logging (SQL Server, EF Core)
- Clean, documented, production-ready code
Message me with your project details and I'll get back to you with a clear plan and timeline.

I'm a Higher Technician in Software Development specializing in .NET backend technologies, including ASP.NET Core and Entity Framework Core — demonstrated through personal projects like a REST API for inventory management with JWT authentication. I also have hands-on experience in AI prompt engineering and chatbot design from a professional internship, including sentiment detection logic and escalation flows. I'm currently seeking my first professional opportunity to apply these skills in backend development and AI integration.
