Antonio J Martinez Sanchez

In summary, I’m a results-driven Sr. Product Manager and AI Product Builder with 12+ years of experience across product management, mobile, and product growth. I’ve worked across fintech, logistics, social impact, mental health, and AI, building and scaling digital products used by millions.

I specialize in Product Management, Product Growth, and User Acquisition, combining hands-on execution with strategic thinking. My experience spans App Store Optimization (ASO), Apple Search Ads, analytics, benchmarking, and UX audits, always with a strong focus on user experience design and data-driven decision-making.

More recently, I’ve been deeply focused on AI-powered products — from ideation to launch — integrating LLMs, AI features, and automation into real user-facing applications. I’ve built and shipped AI-driven experiences such as personalized recommendations, predictive systems, and smart features that enhance engagement and retention. I’m comfortable working across the full AI product stack: from defining use cases and prompts to collaborating on implementation and optimizing performance in production.

I’ve led products from 0→1 and scaled top-grossing apps, improving engagement, retention, and monetization through experimentation and data. I also build my own apps, some of which have been featured by Apple and recognized on major platforms.

I bring a hands-on approach across the full product lifecycle — from AI integration and iOS development to growth and optimization — ensuring high-quality execution and measurable results.
