Master the art of building an intelligent code translation system from scratch. In this course path, you'll develop a robust LLM-powered code translator using Haystack, expose it via a FastAPI backend, and craft an interactive Gradio UI—gaining hands-on skills in modern agentic AI engineering.

See courses

In the first Course, you will develop the core translation pipeline using Haystack's NLP components with an underlying LLM. You will implement the translation routine along with dedicated routines to preprocess incoming code and postprocess the translated output, setting a strong foundation for further enhancements.

Course 2

Exposing Your Code Translator with FastAPI

4 lessons

21 practices

This course teaches you how to expose your Haystack-powered code translation pipeline as a web service using FastAPI. You'll build a clean, maintainable API backend that makes your translation service accessible to other applications.

I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

Full Stack Engineer

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

Abbey Helterbran

Tech consultant

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
