I'm a full-stack software engineer working at the intersection of engineering, product, and AI. My background combines scalable web and mobile development with applied experience integrating LLMs, Generative AI, and AI Agents into real product environments.
I focus on building AI-powered features that are usable, reliable, and aligned with user and business value. I enjoy collaborating with designers and product teams, translating complex technical challenges into intuitive and human-centered experiences. My work spans platform modernization, architecture evolution, performance optimization, and product experimentation, always with an emphasis on usability, system quality, and real-world impact.
Currently, I'm especially interested in roles where I can contribute to the design and development of AI Agents, intelligent interfaces, and applied LLM solutions that enhance digital products and improve user workflows at scale.
