Rob Sanders

I’m a front-end/full-stack JavaScript engineer and team lead with 12+ years building web and cross-platform mobile products used by 1M+ users. I’m especially deep in React and React Native, pairing TypeScript with modern HTML5/CSS3/Tailwind to deliver fast, accessible experiences.

In my current role, I lead a team of 10 developers delivering high-fidelity datasets for AI training, and I own end-to-end QA—from guidelines through final acceptance. I build internal tooling in TypeScript and Node.js to automate data validation, normalization, and REST integrations, helping teams move from ambiguous requirements to clear annotation and QA criteria.

Previously at MGM Resorts International, I shipped and maintained web and cross-platform mobile apps with a strong performance/UX focus. I built RESTful APIs and added automated testing, cutting bug rates by ~20%, improving release confidence, and co-led an Agile adoption effort that increased delivery predictability by ~15%.

I also enjoy turning performance and usability into measurable outcomes: in earlier web roles, I delivered responsive applications with ~99% uptime and faster page loads, resolving 100+ performance issues and improving customer-reported problems by ~25%. Whether I’m tuning UI latency, adding quality guardrails, or collaborating with product and design, my goal is the same—ship practical improvements that business teams can measure.
