SaaS Construction w/Multiple APIs - TypeScript

$25-50 USD / hour

I'm seeking a senior TypeScript developer to create a SaaS with complex functionalities. This would be the initial task to see how you work - depending on how long you take + the logic that you used, we will decide if we work together, may you read it first to assess if that's within your skills or not. Huge complexity will be added, this is 0.1% of the full service that we are building. 1. Sign-up on [login to view URL] (the full code/deployement/states will be run using windmill) 2. Create a small telegram bot using the API (free and fast) to be able to send the messages received by the bot to a webhook. 3. Setup a Telegram webhook to call a windmill workflow. Each time a message is received on Telegram, the Windmill webhook is called. 1. Content Processing: Send the text message received to an OpenAI Assistant so the assistant answer with a message, store all the relevant informations inside mongoDB, the specific assistant's response is not important for now (it can answer anything weird that doesn't matter, we will create specific system prompts later). Be aware of a specific scenario: When Telegram receive a message, the workflow shall start to generate the answer using an OpenAI's Assistant, but if a new message is received before the answer is sent back to Telegram, the initial response shall not be sent (so it must be aborted), the assistant shall generate a new message to take into context the 2nd or N messages received [for this part, you can't remove a message that you added to an OpenAI Assistant's Thread, so a new thread that includes the full conversation must be regenerated (i.e: first user message, assistant response, user message, assistant response, user message, user message)] You are free to think about the most relevant micro-services architecture, keep in mind that a lot of complexity will be added later, so you must use small separated blocks or flows within [login to view URL]

Hi Hermes, We've thoroughly reviewed your project details for creating a SaaS with TypeScript and are excited about the opportunity to collaborate on this complex, multi-API integration using Windmill.dev. Key Points: -Detailed project understanding: -1. Set up a user authentication system on Windmill.dev. -2. Develop a Telegram bot to forward messages to a particular webhook. -3. Configure the Telegram webhook for triggering a Windmill workflow upon message receipt. -4. Integration with OpenAI to process and respond to messages, storing data in MongoDB. -5. Implement logic to handle multiple incoming messages efficiently, ensuring the correct sequencing and response integrity. Queries: -Can you delineate the expected volume of messages our solution should handle? -Are there specific performance metrics or response times we should prioritize for the initial deployment? Recommendation: Considering the potential scalability, it may be beneficial to explore cloud auto-scaling features to efficiently manage the expected load and fluctuations in data traffic. Eager to turn your concept into a reality, with precision and innovation. Regards Tapan S. P.S. Budget and timeline are subject to change as per final requirements

With my extensive experience in both frontend and backend development using JavaScript and TypeScript, I am well-equipped to take on the complexity of your SaaS project. My proficiency spans across the full stack, which makes me proficient in understanding and implementing micro-services architecture such as the one you'll require for windmill.dev. This upper hand not only ensures smooth workflows but also accommodates scalability for future enhancements. My involvement with multiple integrated platforms through APIs makes me a perfect match for your project. For instance, I have previously utilised Telegram API effectively to develop bots, leveraging the functionality in response to user actions. This aligns directly with your requirement of setting up a Telegram webhook to initiate a windmill workflow upon receiving messages. In conclusion, I understand the zero tolerance towards inefficiencies and can assure you my utmost dedication in delivering timely results without compromising on quality. My Webby award speaks volumes about my commitment towards crafting top-notch digital solutions. Let's collaborate and turn this 0.1% task into an amazing further 99.9% that will add enormous value to your offer! Looking forward to discussing the project in detail with you soon!
