Technical Editor — Financial Technology Journalist
Sarah Kim is the technical editor at FinTips and a financial technology journalist with seven years covering fintech and trading platforms. She brings a journalist's rigor to every platform review and comparison guide on the site, holding each article to high standards of clarity, accuracy, and reader value.
Her focus areas are charting platforms, mobile trading tools, and news feed services — the everyday toolkit of active traders. She tests apps the way readers actually use them: on phones and tablets, during live market hours, on free plans as well as paid tiers.
Beyond her own guides, Sarah maintains FinTips' editorial standards. She verifies technical claims against primary sources, cross-references data across vendors, and keeps our most-read comparisons up to date as software and pricing evolve.
