À propos de moi
20 years building and running web backends: Java/Spring Boot, Node.js (Express), PHP (CodeIgniter), React/Vue, MySQL/PostgreSQL/MS-SQL, Linux + Nginx + GitLab CI. I fix what is broken and ship what is half-done: API bugs, Nginx 502/504, failed deploys, slow queries, legacy-to-Spring Boot migrations, e-commerce/CRM integrations. How I work: written brief first, fixed scope, daily written update, a short screen recording when I deliver. Remote and async (UTC+9 - your night is my working day). No AI/ML claims, no mobile-native. If your problem is not in my list, I say so on day one.... Plus d’infos
