APP Design & application Expert

I am the Managing Director of a UK based company. Over the past few months, we have been working with a development company to build an app, which is currently around 50–70% complete. This is our first experience developing a product like this. We have also been working with a freelancer, but their experience; particularly in aesthetics, user flow, and overall customer experience, is not at the level we require. As a result, we are looking for a high-end app developer or product specialist to work with us on a consultancy basis. We expect this to involve approximately 5 to 10 hours over the next couple of weeks. Initially, we would need someone to: * Understand the project through videos and written documentation * Join us on a live demonstration with the existing developers * Analyse and review the near-final product * Provide strategic feedback on user experience, flow, functionality, and overall polish We have found that many developers are highly technical but can only work to guidance as appose to initiative. What we are looking for is someone who can think independently, understand both the business owner and end customer journey, and identify improvements proactively. The app is designed for business owners and their customers, and includes features such as: * Marketing tools * Loyalty schemes * Event management * Prepay / pre-order functionality * Customer interaction and engagement Fluent English and confidence in face-to-face meetings are essential. If you believe you are the right person to help, please get in touch. - I would also like to add; if you have applied before. We have your details on record & will contact you, if we want to consider you for the assignment. Thank you.

Seeking Experienced Smart Contract Developer (3+ Years)

Hello everyone. We are putting together this multi chain crypto trading platform right now. And we need two smart contract developers to come on board with us. It would be great to get one who really knows EVM and has solid experience with Solidity. Then the other one should feel okay working with Rust, especially for those non EVM chains. I think having some background with Web3 libraries counts a lot too. And if you have done actual integrations on blockchains in real projects, that stands out even more. If you are into this kind of thing, go ahead and apply if it seems like a fit.

Hi, I need a website for my company. I offer website, web shop, app, and software programming services. The website should be professionally responsive and mobile-first.

Prices should be listed and there should be a button at the end to contact us.

The website should be SEO and GEO optimized so that it is understandable and findable for ChatGPT, Gemini, and others.
