We have existing project in Python that is serving as a backend for an IoT project of our company. It should handle data streams from tens of thousands of sensors, write them to database and analyse values in meaningful ways. After several trials it turns our it is too slow to handle data that is pushed to it. We need you to: * look through the source code, * find bottlenecks, * optimise everything, * make it super-fast, * tell us what we have done wrong, * implement meaningful tests we can benchmark our data handling * and more. We deploy on Amazon EC and Amazon RDS and use Python 3. We will consider more suitable options for parts of our application if you convince us. We will expect full time commitment (8 hours per day / 5 days a week) with at least 1 hour per day available for Skype meeting during UTC+10 9am - 5pm, all other times available on chat channel. To start, you will branch our project and can go crazy with it, you get full access to your aws instances to deploy your solution. show us how your optimised version benchmarks against what we have and work with us to explain details. easy. payment is on monthly bases, initial contract is for minimum of 3 months. please set your bid with full contract price for 3 months. consider your monthly payment to be one third of the full project price as if contract is extended to 4 months or more, this is going to be your ongoing monthly salary.

Hi. I'm a programmer from Russia with strong skills in Python. I have good knowledge of databases and SQL queries that helps me to create applications that manage and store data. Mostly I worked with PostgresQL and SQLite, but I'm also familiar with MySQL and Mongo. Amazon Redshift won't be a problem to me. I suggest to measure every piece of your code and find operations that take the majority of time. After that we'll be able to decide what to do with those pieces. One way to optimize code is to refactor it. Old code often works slow and needs to be rewritten. Another way is to introduce parallel processing. If you can split the whole task into several subtasks and assign each subtask to a separate thread, it can increase speed of processing in several times. I also want to mention asynchronious operations. There can be a situation that code waits for some event to happen. While waiting, it does nothing. Async operations allow to process data in the meantime. My bid is final, I don't increase bids. I can work 5 days a week, 8 hours a day. If you're interested, feel free to contact me. All the best, Sergey.

Hello, Nice to meet you. Honestly, this project made me excited, because this is what we love the most and this is what are are great at. It may take time, it may get rough, but we will achieve it ultimately. What I want to know. 1. What is average calls per second to the python server? 2. Are you using Flask or some other framework to handle the calls? 3. Most importantly, what DB is used? Is complete architecture on a single system or there are clusters for DB and application? 4. Are there any architectural documents available? 5. Have you conducted load tests yet? If yes, please can i see the results. 6. Can i know the nature of the project, its concept :) About me : I am Zeeshan, and for most part of last 12 years working over C++(Windows and Mac desktop), Python/Node.JS/PHP (Web and API) and Big data(NoSQL), I have now been working as Application architecture and give consultancy to different firms as well regarding their architectural needs and while I have team here, we get that implemented too. I will take 4000 USD(not AUD), take home (Freelancer adds 10% commission), and hopefully can help you with all of your needs. I can also give you examples of how we worked for different projects and how we manage to achieve results. Look forward having details conversation with you. Thank you, Zeeshan
