Summary
👤
Senior🎓
Top SchoolOleksiy L is a founder-engineer and CEO based in Philadelphia with 11 years of experience building production software across mobile, backend, and ML-focused systems. He co-founded Sojourns Inc and previously shipped end-to-end features at Candid—owning Django/PostgreSQL backends and React tooling—and was a founding engineer at TWOSENSE.AI where he bridged ML models, mobile inference (TensorFlow Lite), and data pipelines. His work spans embedded and desktop clients, Android foreground services, Chrome extensions, and custom multi-threaded Java frameworks, reflecting a rare blend of product ownership and low-level systems design. Comfortable moving models from research to shipping products, he also has a published undergraduate research project and a formal MS in Computer Science, signaling both academic rigor and hands-on delivery. An early habit of rethinking internal tooling for reliability and efficiency suggests he optimizes not just features but the developer experience behind them.
