✅ Meta App Approvals — Guaranteed. Or You Don't Pay. While others guess their way through Meta's review process, I've spent 10+ years engineering the systems behind it. I don't just get approvals. I build the products that need them. 📊 The Numbers: 🏆 270+ Projects Completed 💰 $200K+ Earned on Upwork ⭐ Top Rated Plus | Top 3% Globally | 5-Star Rated 🚀 60+ Apps Approved in the last 6 Months 🔐 400+ Permissions Secured 🛠️ 30+ SaaS Products Built from scratch on Meta APIs Most freelancers submit your app with hope but I know exactly what Meta's reviewers want because I've been in this ecosystem since before most developers knew the API existed. 🎯 You bring the vision. I'll bring the build and the badge. 🚫 Rejected by Meta? I fix that fast. If you're hitting the "Invalid Screencast" wall or stuck in an endless rejection loop, you're not alone and you're in the right place. I've rescued hundreds of clients from exactly this situation. I handle everything, I record the screencast myself, prepare the full submission, and manage direct communication with Meta's review team until you're approved. Most clients get the green light in 1–10 business days.

I build production-ready software by combining strong software engineering principles with modern AI-assisted development. Rather than treating AI as a code generator, I use tools like Claude Code, Cursor, Codex, ChatGPT, Gemini, and GitHub Copilot as engineering partners. My workflow focuses on defining architecture, constraints, implementation rules, and coding standards before any code is generated, allowing me to produce more accurate code, minimize debugging, and deliver reliable solutions faster. I specialize in building: - AI Builder workflows - AI Chatbots & Conversational AI - AI Agents & Workflow Automation - AI-Assisted Web Applications - REST APIs & Backend Systems - SaaS Platforms - Internal Business Tools - Custom Automations - Full-Stack Web Applications Technologies I regularly work with: Backend - Python - FastAPI - Laravel - PHP - REST APIs Frontend - JavaScript - TypeScript - React - HTML - CSS - Tailwind CSS - Alpine.js - Livewire Mobile - Flutter AI & Automation - Claude Code - Cursor - ChatGPT - Gemini - Codex - Prompt Engineering - API Integrations Deployment: - GitHub - Vercel - Netlify - Coolify - Docker How I work: Most AI-generated projects become difficult because the AI lacks proper context. Instead of immediately asking AI to write code, I first define: - project architecture - responsibilities - coding standards - implementation constraints - development roadmap Only then do I use AI to generate the implementation. This approach dramatically reduces unnecessary iterations and helps produce maintainable, production-ready software. I'm also comfortable reviewing AI-generated code, identifying subtle issues, and refining implementations rather than repeatedly regenerating code. Recent work: Recently, I completed Upwork's Talent Accelerator AI Chatbot project, where I designed and built a customer support chatbot using FastAPI, hybrid intent recognition, finite state machine (FSM) conversation management, and a responsive frontend. The project received a 5-star rating, with the client commenting: "Really impressed with the final results and the attention to detail throughout the project." Whether you need an AI-powered application, chatbot, automation workflow, API integration, or a full-stack product built efficiently, I'm ready to help. If you're looking for someone who can turn ideas into reliable software quickly using modern AI development workflows, I'd be happy to help.
