About John
Vibe coding Expert | Base44 | Replit | Lovable | Supabase | Claude AI
Lagos, Nigeria - 8:55 pm local time
Most AI-generated apps look great in demos but fail when real users arrive. APIs break, authentication stops working, databases become unstable, Stripe payments fail, deployments crash, and performance drops.
That's where I come in.
I'm JOHN, a Full-Stack Developer, AI SaaS Developer, Vibe Coding Expert, Base44 Expert, Replit Expert, Lovable AI Developer, Supabase Specialist, OpenAI Integration Expert, Claude API Developer, and Automation Engineer.
I help startups, founders, agencies, and businesses build, debug, optimize, deploy, and scale production-ready applications using Base44, Replit, Lovable, Bolt.new, Cursor AI, Claude Code, v0, Supabase, OpenAI, and modern full-stack technologies.
Clients hire me to transform ideas, prototypes, MVPs, and AI-generated projects into scalable software that is reliable, secure, maintainable, and ready for growth.
