ABOUT

I am a Product Engineer and Global Senior Product Manager who thrives at the intersection of engineering, product thinking, and AI. I don't just write code; I own features end-to-end—from architectural design to production launch—focusing relentlessly on customer experience and business impact.

With over a decade of experience across the U.S. and Europe, I specialize in building AI-driven frontend experiences and foundational data platforms. My background spans scaling global health data systems serving over 2M patient records, leading LLM-based products that increased retention by 25%, and architecting API frameworks that improved reliability by 40%.

I excel in fast-paced environments where rapid iteration and outcome-driven development are paramount. Whether it's optimizing LLM latency or designing intuitive human-in-the-loop workflows, my goal is always to ship meaningful outcomes, not just features.

    llm_result = call_llm(user_input)
    if requires_human_review(llm_result["confidence"]):
        return {"status": "needs_review", "result": llm_result}
    return {"status": "approved", "result": llm_result}
