Hello everyone! I'm looking for a Backend Developer (NestJS) to work on a new project. What needs to be done Develop a REST API using NestJS. Prepare and maintain documentation through Swagger (OpenAPI), so that the frontend developer can automatically generate a client using Orval and always work with the current specification. Design a clean, scalable architecture that will be easy to maintain and develop. Requirements Strong knowledge of NestJS and TypeScript. Experience with PostgreSQL. Experience integrating with Supabase: authentication and authorization; working with the database; using the platform's built-in features. Experience integrating Stripe (through Supabase features). Understanding of API security principles, authorization, data validation, and application protection. Ability to write clean, structured, and extensible code. If you have relevant experience, please send: examples of projects or GitHub; your desired rate (for the screens I provided, so I can understand your rate, hourly is inconvenient as it's unclear what volume of work will be done, everyone has a different pace);

I need content from WhatApp pulled into Monday.com project management plans / task lists. The connection currently created is already transferring information to Monday.com but not to the right project boards and not including owner and timeline. I need help with this connection.

I am looking for an experienced developer or a small team to create the ENGoose website - an online platform with ready-made ESL materials for English language teachers. This should not be an ordinary informational site or landing page, but a convenient library of educational materials with a paid subscription, personal accounts, and the possibility of further development. Currently, I am prioritizing WordPress, but I am open to considering Bubble or another well-argued technical solution. Main functionality A modern responsive website for computers, tablets, and smartphones. A catalog of ESL materials with cards and separate lesson pages. Filters by levels, topics, types of materials, grammar, and other parameters. Search and sorting of materials. Free and paid materials. Monthly subscription. Integration of a payment system compatible with Ukrainian individual entrepreneurs. Registration, login, and personal account. Adding materials to favorites. Protected access to PDF files and Canva links. Administrative panel for self-adding and editing materials. Main informational pages: FAQ, pricing, contacts, terms of use, and privacy policy. Timer until the next material is released. Possibility of further expanding functionality. Additional features Please separately evaluate the possibility and cost of: private notes and personal tags for lessons; a simple planner: date, time, student name, and status "scheduled/conducted". In your proposal, please indicate: recommended platform and its advantages; examples of similar projects; estimated cost and timelines; what is included in the proposed amount; monthly and annual expenses after launch; terms of further support.

There is a sales funnel for the online store that we want to replicate for ourselves. It looks like this: The main landing page (the product that is primarily for sale, for example, a shirt). Then the checkout page (where the person enters their details and chooses how many shirts they want to buy, for example). Then they go further down the funnel and are offered upsell 1 (socks) + then upsell 2 (underwear) and finally the thank you page. You can see how this should work in terms of page transitions and logic here (you need to get to the end to the thank you page) https://3plus3.heroman.com.ua/standard/. We have examples of pages that we want to create for ourselves. So for us, essentially, we will copy the design - layout - fill it in with our product. The upsell pages will have the same design and structure as on the site I shared above (underwear). You will not need to fill the pages with information, just gather the skeleton - so that the application comes through correctly. Also, you do not need to come up with the structure of the pages. From you, essentially: Copy and layout. Set it up to work technically correctly. Show how to work with this so we can do it ourselves. There are 2 website builders in mind, we are currently working closely with 1 and need to understand if we can deploy this on it (but I read in GPT that it is possible).

It is necessary to deploy a website from a full backup on a new hosting The website is created on Drupal Please send your proposals
