Please read Jesse’s Obituary below

Jesse Osezele Boma Onolememen was born on 27 April 2003 in Dublin, Ireland, to Barrister Felix Onolememen and Esther Pepple Onolememen, and was a deeply loved brother to Oseojie Stephen Onolememen and Dr Deborah Onolememen. Raised in Lucan, Dublin, he was educated at Griffeen Valley Educate Together, The King's Hospital School, and The Institute of Education, before studying Electrical & Electronic Engineering at University College Dublin.
From childhood Jesse showed an unusual mind — teaching himself to code at seven, calling himself "self-employed" by twelve, and building his first app, Number Tap, at thirteen, the same year he founded his fashion and media brand ONEPLUSONE. At sixteen he built another software project, MURCH. As he put it: "I design not by métier but through my manière d'être."
Jesse graduated UCD with an A-grade engineering degree and had already begun his professional career — contributing to the Tyne Tunnel's transformation in the UK, then joining RemNote at nineteen, where he led a team of six building its mobile apps. In 2024 he joined Pinterest in Dublin as a Full Stack Engineer II, scaling a system he built to over 10 million requests per minute. In 2026 he took his boldest leap yet, joining Augustus in New York as its first engineer to help build a bank — a chapter that carried him on to Berlin, where he spent his final months building the future he believed in.
Beyond his work, Jesse loved fashion, travel, cooking and baking, and was athletic — a runner with a 45-minute 10K, a skier, and a rugby second-row. He was a lifelong sickle cell advocate, serving as Youth Coordinator for Sickle Cell Society Ireland and helping raise over €5,000 for Crumlin Hospital. In 2023, following the loss of his beloved sister, he co-founded the Reme Onolememen Sickle Cell Research Foundation in her honour. At the centre of it all was his faith — Jesse loved God deeply, and his analytical mind and his spirituality lived side by side with ease.
