Senior Software Developer at Optable
Montreal, Quebec, Canada
Summary
👤
Senior🎓
Top SchoolXavier Capaldi is a Senior Software Developer in Montreal with a strong experimental physics background and eight years of experience bridging lab research and production engineering. Trained in microfabrication and DNA sequencing workflows, he leverages that hands-on experimental rigor to design reliable data pipelines and instrumentation software using Go, Python, PostgreSQL and BigQuery. He transitioned from publishing scientific papers to shipping production code at Optable, where he rapidly progressed from developer to senior engineer by focusing on modular design, performance, and clear documentation. Xavier is an agile learner who quickly picks up new languages and tooling (actively improving full‑stack JavaScript, C/C++, and Elisp skills) and applies research-grade problem solving to ambiguous engineering challenges. A less obvious strength is his long history of end-to-end project ownership—from founding a web services company at age twelve to coordinating large teaching labs—giving him practical experience in automation, user-focused design, and team coordination.
