Most AI-built apps look great in the demo and fall apart the moment a real user logs in. I fix that gap. I combine AI-native development speed (Lovable, Replit, Base44, Bolt.new, Emergent sh, Claude code) with real backend engineering discipline - secure auth, proper database architecture, clean scalable code - so what you ship doesn't just work in a demo, it works in production. Who I work with Non-technical founders, Existing Business owners, early-stage startups, and busy teams who need to move fast without inheriting a mess of technical debt six months later. What I build: Full-stack SaaS MVPs and production-ready web apps, from concept to launch AI-powered applications: LLM integration (OpenAI, Claude, Gemini), RAG pipelines, semantic search, AI agents Advanced Functional Web Developments Secure database infrastructure (Supabase, PostgreSQL, Firebase) with proper Row-Level Security Custom web apps, client portals, and interactive dashboards Web app or development completion Website and Web app Domain migration Workflow automation connecting your tools (n8n, Zapier, Make) Payment and API integrations (Stripe, PayPal, REST/GraphQL) Problems I fix most often: Broken or half-finished AI-generated prototypes you don't know how to repair Unsecured auth flows and database instances that won't survive real traffic Apps that crash the moment they scale past a demo Rigid codebases where adding one small feature turns into a rebuild Domain migration within and across hostings Complete halfway setup web applications Core stack: React, Next.js, Node.js, Tailwind CSS, Supabase, PostgreSQL, Firebase, AWS, Vercel, Github Why clients work with me: ✔ Clean, scalable architecture - I build systems you can grow with, not throwaway prototypes ✔ Fast delivery without cutting corners on security or structure ✔ Transparent communication - you're never in the dark on where your project stands ✔ I test and validate as I build, not after something breaks I'm newer to Upwork specifically, but not new to building - I run active freelance projects across web development, automation, and AI integration, and been experienced with AI and Web app development and currently improving with advance courses, this keeps me sharp on research rigor, data handling, and systems thinking. That discipline shows up in how I build software: documented, tested, and built to actually hold up.
