Full Stack App Troubleshooting and Backend Developer

Chi sono
I help founders and small teams fix broken web apps, backend errors, authentication issues, API connections, database problems, and failed deployments. I work with Lovable, Bolt, Replit, React, Vite, Supabase, Vercel, Java, Spring Boot, REST APIs, MySQL, and Redis.
With 8 years of backend development experience, I focus on root-cause diagnosis, clear scope, and practical fixes without unnecessary rebuilding. Send me the error, screenshots or logs, expected result, tech stack, and recent changes. I will review the issue and recommend the right package before you order.
