Suggested by whom and for what purpose? It's not clear what you like to do and what is the goal of pursuing any certification. Many developers have no certifications at all (I've never had any, for example). So, once again, like in "Alice in Wonderland", if you don't know where you want to get to then it doesn't matter where you go.
In general, you can see a list of all valid certifications here: https://training.sap.com/certification/validity
If you simply search (Ctrl-F) for "SAP Certified Development" on that page, you'll find all items that are development related. I do not recommend using search bar on that website since it seems to return completely random and irrelevant result.
Also, recently revamped SAP Learning Hub is supposed to have some kind of "learning journeys" that should point to either certifications or just general courses or learnings that pertain to specific areas of expertise. I don't have a link for those but perhaps if you go to LH you might find them there.
