Senior🎓
Top SchoolJohncarlo Cerna is a full‑stack software engineer with nine years of hands‑on experience building production systems, currently focused on delivering software at Power Home Remodeling after leading a 9‑engineer team at USCIS. He has deep Ruby on Rails expertise—demonstrated by meaningful contributions to the rubyforgood/casa volunteer management platform and by anchoring Rails work in large-scale asylum and refugee case systems that handle security checks for millions of applicants. Comfortable across the stack, he’s shipped features at Microsoft and built high‑frequency data acquisition apps for NASA, blending product ownership with solid testing and TDD practices. A collaborative engineer who champions pair programming and extreme programming, he also brings mentorship experience from university programs and a knack for algorithmic thinking (he implemented a Stable Matching–inspired mentor matching system). Outside work he recharges with foosball, challenging games, and bachata dancing—showing the same persistence and focus he brings to hard engineering problems.
