Cover image for I designed and built Zentro’s
I designed and built Zentro’s student-housing experience across its marketing website and mobile app. The product helps students find off-campus housing, browse listings, compare options, save favorites, and schedule tours with clearer next steps. I worked across the product structure, responsive web experience, mobile flows, and supporting integration work.

Cover image for Build research-grade betting intelligence systems
Build research-grade betting intelligence systems that monitor public market and wallet data, score specialist consensus, deliver alerts, and evaluate signals with reproducible backtests. AI-agent workflows for monitoring, triage, and routing can be included when explicitly scoped. This is research and engineering work—not betting advice, guaranteed accuracy, or promised returns.

Cover image for I designed and built the
I designed and built the Stats&Bet marketing site for a value-betting platform. The site turns a data-heavy product into a clear product story: opportunity detection, odds management, performance tracking, Telegram delivery, and a unified dashboard. I created the responsive landing-page structure, product visual sections, pricing area, FAQs, and conversion path.

I designed and built FR1Bet, a Formula 1 prediction platform based on pool betting. Users choose race outcomes, compete with the community, and play for the shared prize pool. I built the Spanish landing page and product experience, including the visual system, responsive layouts, localization, and core prediction flow.
