About Liam

Computer science student at EPFL, I offer freelance services in backend development and data processing. I am proficient in Java, Python, Scala, and C, and I enjoy solving concrete problems: creating an API, automating a repetitive task, or building a data pipeline.
Available for short, well-defined missions (a few hours to a few days). I am serious, autonomous, and I deliver clean, documented code.
