✅ 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: 🏆 260+ 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 things that actually work and deliver fast. Over the past few years I've built and shipped real products — not just freelance gigs, but full systems I personally use and maintain. That includes a complete inventory management system for an e-commerce brand (Shopify + Shiprocket integration, RTO tracking, courier scoring, fraud detection), an algorithmic trading bot running on live Indian markets, and an automated content posting pipeline. All Python, all production. My sweet spot is backend work and automation — REST APIs, custom Python scripts, database design, third-party integrations, AI-powered tools. If you need something connected, automated, or built from scratch, I can do it. I work fast, communicate clearly, and won't disappear mid-project. If something needs fixing after delivery, I'll fix it — no drama. What I can help with: Python scripting and automation REST API development and integrations Custom software and internal tools AI integrations (Claude, OpenAI Gemini) Database work PDF generation, data pipelines, web scraping If you have a problem and need it solved quickly, just message me.
