Senior🎓
Top SchoolChristopher Rosario is a Staff Software Engineer with 13 years of experience, specializing in Ruby on Rails and backend systems, currently driving platform work at Lightspeed Commerce from Los Angeles. He spent seven years honing Rails expertise and the last several focusing on onboarding third-party data sources for ML models and breaking a monolith into service-oriented components. Christopher transitioned into a lead role at ZestFinance managing a small team, but is now seeking to return to an individual contributor path where he can ship product-focused code. Comfortable across the full stack, he brings pragmatic architecture experience and a track record of integrating complex data pipelines to improve model inputs. A practical problem-solver, he pairs hands-on engineering with an appreciation for maintainable refactors and cross-team data integrations.
