React/Next.js Upwork Jobs

We are seeking a developer to build a proof of concept react native app to take the existing functionality of a desktop based C# app that communicates with an Arduino Uno via USB and convert it to a react native app that communicates over Bluetooth. We have an existing firmware file for the Arduino and we are assuming an HC05 module would be required for providing Bluetooth functionality to the Uno. The current functionality is quite simple and the UI required for the react native app does not need to be complex. The requirement is for a science project rather than a commercial product. Anyone expressing interest must have recent experience building react native apps to work with Arduino via Bluetooth. We do not want to work with a project manager or agency, please only express interest if you would be the developer working on the project. We need a quick turnaround on this project. Look forward to hearing from you.

Hi there! My team and I are looking for an ultra-modern, trendy, and interactive website with catchy animations and graphics. We have in-house 3D designers - many graphic assets for the website have been made already or can be made (cool 3d moving renders etc…) Project details: Fashion / NFT website References: https://ift.tt/31wcgSU is the ideal “simpler” layout) https://ift.tt/3DBlPNg is the ideal “complex” layout) **if you cannot design/build a website like the above examples this job is not for you** We would be open to emulating directly either of these sites, with the same page count and layout or creating something new, but on this same design level. Ideal timeline: 1-3 weeks. We realize that this much faster than a normal timeline, however, our rough timeline is a necessity for our current situation. Requirements: I believe it needs to be done in React as this will allow us to build in the web3 capability. If this is impossible, we will consider other alternatives. If you are not a full-stack dev (can't build out the backend/react) but have the skillset to design the UI/UX mock-up and assets - we would still like to hear from you! Budget: Negotiable Thank you!

We are a IT corporation and looking for a developer or a team who can help us developing a "**location based chat app**". Here is the brief summary of the concept and we will give more information on Whatsapp upon the agreement of NDA. - You can make a chat room if you and the other user are/were in the location within the certain range. - The chat room expires within certain hours. - The chat room includes some information about the location where they cross or were. - The operation above would like to run on background, which means I am expecting experience like this: A user open this app later the night and see how many rooms (or so called matching) are created by where she or he has been earlier that day. At the moment, we **only have core concept of the app**, while there is no wireframe or design document ready yet. So we are looking forward to develop this app by communicating and making consensus of the product by many communication like in agile process. Here is the app spec we want: - We prefer the app to be developed in a hybrid platform such as **React Native or Flutter**, so we can cover both iOS and Android. - Backend solution is not specified and we would like to have suggestion after the meeting. These are some of the requirements my team prefer: 1. Confidence: Must be able to suggest and have the ability to implement the idea into a product. 2. Communication: Needs to feel comfortable with English. Will use Slack for communication. 3. Sharing: Weekly report is necessary. Will hold a meeting when it's needed. 4. Together: Prefer access to source control. Test and share feedback through many mid-build review to build this app together in agile style. Hope we can find a great partner to develop this idea into a great product together. Thank you.
