I am a highly skilled and experienced professional with a passion for designing, developing, and maintaining software systems that meet the highest standards of quality. 🚨 You can count on me to get your project done as soon as possible. I help companies improve their workflows & processes by: ✔️ Implementing internal tools to boost productivity. ✔️ Integrating data systems for optimizing business decisions. ✔️ Automating repetitive tasks to save time and money for the entire organization. Nowadays, there are so many online apps to assist with project management, scheduling, sales, marketing, customer support, and so on. It may be hard for many businesses to choose the right software for their needs. Sometimes, businesses are not using the software to its entire potential or in a way that would increase their productivity. This is where I come into the picture! My business and technical experience and my in-detail understanding and vision of the best possible systems and processes are available to you for optimizing your company’s overall functioning and productivity. Here's my process: ① Initial Consultation - We will have one or more conversations to describe and understand what software you are currently using; what your existing workflows & processes are, and what goals you want to achieve in terms of process optimization. ② Propose Solutions - Based on the initial findings, I will create a shortlist of software tools that can be used to meet your company’s needs, and then I can assist with the selection of the right software. ③ Build & Test - I will design and implement a complete “work system”, and test it within agreed upon scenarios. ④ Iterate & Automate - After testing the final product and after gathering feedback, I will make any necessary changes to your system & implement additional automations, if needed, to ensure maximum productivity and user experience. ⑤ System improvement – long-term collaboration. I can offer technical support even when you have a system that you are happy with, but want to continue to improve it.

✅ 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.
