Afrimian contributed to the microsoft/Power-Fx repository by developing a constructor enhancement for the QueryMarshallerSettings API, focusing on improving API ergonomics and backward compatibility. Using C# and leveraging C# 8 object initialization syntax, Afrimian enabled users to configure encoding options such as date and boolean encoding as integers, which supports teams working with legacy C# compilers. This feature reduces boilerplate code and broadens the usability of the API for projects constrained to older language versions. The work demonstrated a targeted approach to compatibility and maintainability, though it was limited in scope to a single feature without addressing bug fixes during the period.
