About Me

Developer, Writer, and Photographer

With over 30 years of experience as a full-stack software developer, I bring a wealth of technical expertise and creative problem-solving to every project I undertake. In addition to my career in development, I have spent two decades honing my skills as a writer, crafting thoughtful and engaging content that resonates with diverse audiences. More recently, I’ve embraced photography, capturing compelling visuals that tell stories and complement my creative pursuits. My multifaceted background reflects a deep passion for innovation, storytelling, and continuous growth.

I currently live and work in central Japan, and I am looking to take on more work to help small businesses and non-profits around the world achieve the goals they've set for themselves.
