    Are you looking for a Web Developer specialist in Node.js, Express.js, React.js, MongoDB, Javascript, TypeScript, or Python, Django, and Flask. Then, I am the person who is the PERFECT MATCH for your projects. *****************KEY FACTS****************** It must be quite irritating, right? Getting thousands of messages from people that tell you they know how to build your product properly, but they actually don't have any idea about what you want. Let me be honest with you: I've been there too. Most service providers focus on just technical stuff. "Oh, you want an API? Yes, I can build the integration for you. Oh yes, and I can also create a video, and actually everything, just put an Order!" No! I want you to understand my business idea, so you can help me find the best solution to your users' problems! Sounds familiar? Now, let me cut through the noise and quickly introduce myself: My name is Umair Jahan, I help entrepreneurs like you build custom software solutions to help with real people's problems. I focus on helping YOU solve the problem of your users. I speak your language: You don't need to try and pretend you know everything about APIs, integrations, and all these boring things. The technical part is on me. I just need your creative vision to implement the idea into life. I want to build long-term and sustainable relationships with clients and that’s why I am always focused on quality of work and timelines. Please feel free to contact me if you need me and I'll be more than happy to help Thanks!!
