iOS Architect turned AI/ML Engineer
Technical Architect with 14+ years of iOS expertise, now focused on building AI/ML-powered applications. I bring a rare combination of deep mobile engineering — apps shipped to millions at Costco, Agoda, and DBS Bank — with hands-on experience in machine learning, LLMs, and intelligent systems. Currently building AI/ML projects that bridge the gap between powerful models and real-world mobile and web products.
