II help founders, startups, and businesses turn ideas into production-ready AI SaaS products fast.
Using modern AI-assisted development tools like Lovable, Replit, Base44, Supabase, and OpenAI, I build scalable web applications, AI automation systems, SaaS MVPs, dashboards, and workflow tools that are structured for real users, payments, and growth.
Most MVPs fail because they are rushed, poorly structured, or impossible to scale.
I solve that by combining rapid AI-powered development with real full-stack engineering so you get:
✔ Fast delivery
✔ Clean architecture
✔ Scalable backend systems
✔ Secure authentication
✔ Working AI integrations
✔ Production-ready SaaS infrastructure
What I Build
• AI SaaS Platforms
• Startup MVPs
• Full-Stack Web Applications
• AI Agents & Automation Systems
• ChatGPT / OpenAI Integrations
• Dashboards & Admin Panels
• Client Portals & Internal Tools
• Stripe Subscription Systems
• Workflow Automation
• API Integrations & Webhooks
• CRM & Business Systems
• AI Chatbots & Assistants
Platforms & Technologies
AI & Development Tools

Database & Infrastructure
Supabase • PostgreSQL • Firebase • MongoDB • Authentication • APIs • Webhooks
AI & Automation

What You Get Working With Me
⚡ Fast MVP Development
⚡ Production-Ready Applications
⚡ Scalable Architecture
⚡ Secure Backend Setup
⚡ Responsive UI/UX
⚡ AI Integrations That Actually Work
⚡ Clear Communication & Fast Updates
⚡ End-to-End Support From Idea to Launch
I don’t just build prototypes.
I build AI-powered products that are ready for users, payments, automation, and scaling.
Whether you need:
• a Lovable.dev app fixed
• a Replit MVP launched
• an AI SaaS platform built
• Stripe subscriptions integrated
• automation workflows connected
• or a full startup product developed from scratch
I can help you move from idea to a working product quickly and efficiently.
Send me an invite or message with your idea, workflow, or project requirements, and I’ll help you plan the fastest and cleanest way to build it.
