Top SchoolMariusz Lapinski is a seasoned software engineer and repeat founder with a decade of experience building products from startup MVPs to large-scale services at Google. He combines strong backend engineering (C++, Python, Ruby on Rails) and full‑stack experience with a knack for product design, having launched PDF Otter to automate PDF filling and led Teamies to host virtual team‑building events. At Bloomberg and Indiegogo he built data pipelines and web platforms; at Pillow and BOD Technologies he helped shape product direction and early technology stacks. Now based in New York, he focuses on fostering remote community among employees and students while remaining hands‑on in engineering. Unusually for an engineer with enterprise experience, he also runs live events (Family Feud and Trivia) as part of his product repertoire, blending technical delivery with user-facing community engagement.
