À propos de moi
I help non-technical business owners build, fix, and understand their apps, without the jargon. Tell me what you want, even if it's vague like "make it feel better". I'll turn it into something concrete and explain every step. 10+ years as an engineer, from 24/7 banking systems to startups in healthcare, education, and real estate. I take over projects others left half-finished, and I've trained new engineers, so explaining clearly is part of my job. Stack: Java/Kotlin (Spring Boot), React, Next.js, Laravel, Flutter, AWS, Claude. Based in Japan. I work by chat and reply fast.... Plus d’infos
