Momo
Head of curiositySilver coat, blue eyes, convinced the interesting thing is always one room over. Momo is the studio’s appetite — the part of the job that keeps asking what else the product could be.
Momokaya is a one-person product studio in Tallinn, run by Oisin Coveney — and supervised, loosely, by two huskies named Momo and Kaya. Senior engineering, clear communication, a real bias for shipping.

Oisin builds products end to end. At Metabase he shipped the React Embedding SDK and redesigned global search; at Alvin he was the founding engineer and built the product UI front to back; before that came full-stack work at GoLinks and Clearwater Analytics, and DevOps at Citibank — the details are on the Work page. Momokaya exists because the part he loves is the part most builds skip: the polish that makes a first version feel real instead of merely shipped.
Irish-Filipino-Californian by way of Tokyo, he now builds from Tallinn — playing midfield in the city’s amateur football leagues and still cheerfully failing to learn Estonian. MSc in Computing with first-class honours (Dublin City University); BS in Computer Science, summa cum laude (San José State).

Black-and-white coat, brown eyes, completely unbothered. Kaya is the studio’s standard — proof that software should feel composed, even when the system behind it isn’t.
