Full-Stack & AI Developer | MVPs, Chatbots, Lead Bots | Ship in 72h

I build and ship working software fast, often in 72 hours. SaaS MVPs, AI receptionists, and lead-response systems, live on a real URL for a fixed price. Non-technical founders and busy business owners don't need a co-founder or a six-week agency engagement. You need a working product in front of users this week. What you get with an MVP build: - A deployed Next.js app on Vercel or your host - Stripe subscription billing, wired and tested - A database (Postgres / Supabase) - The one core flow that makes your product work - Full source code, transferred to your GitHub - A handoff walkthrough and one week of bug-fix support I also build AI receptionists and chatbots that answer, qualify, and book leads 24/7 over web chat and SMS, so businesses stop losing the leads they currently miss. Recent build: LeadsLockAI, an AI lead-response system for home-service businesses that texts missed callers back within 30 seconds, qualifies them, and books the job (Next.js, Supabase, Twilio, Vercel). Need something smaller? I also build single landing pages, multi-page business websites, and one-off bug fixes, all at flat fixed prices. I've shipped production SaaS products with Stripe billing, real-time dashboards, multi-tenant platforms, AI chatbots, and automation tools across Next.js, React, FastAPI, Flask, and Node. I move fast with modern tooling without cutting corners on auth, payments, or data. Not sure where to start? Book a 297 dollar audit: a 24-hour technical review and build plan that credits toward a full build. Tell me what you're building and I'll tell you exactly how I'd ship it.
