So currently we are a seller on eBay what I'm looking to do is simplify the process so we can get pull sheets for our puller in the warehouse and light room. Basically what happens is this: 1. Orders come in on a daily basis from 2 eBay stores. 2. We download what's called "Awaiting Shipments" (Awaiting Shipments Excel Sheet) 3. From the 2 "Awaiting Shipment" files for both stores we make 3 separate Pull Sheet files. One for all the Large items (Fenders, Bumper Covers, Grilles, Radiator Supports and a couple others) one for the hoods, and one for the small items (Lights, Mirrors, Radiators, AC Condensers). All these items can be portioned out based on our classes. ie Lights is class 19 hoods is class 10 and so on. 4. The information used to populate the pull sheets come from 4 different files. 2 text files (Location File Excel Sheet, Class File Excel Sheet), the "Awaiting Shipments Excel Sheet" File that is pulled off of eBay, and the SKU Key. The general concept is simple but some data needs to be incorporated and manipulated in order for the files to also include BIN locations, Quantity, Type, Custom Label, Item Title, and Sales Order # along with some columns to the side for the puller to mark either Y or N to indicate whether they pulled the item or not. (Sample Pull Excel Sheet) The goal is to simplify this process as much as possible to where anyone who comes in can generate a pull sheet without going through any of the steps. Currently we have to make the document to include all the additional information so we're looking to simplify this so we don't need someone with knowledge of excel or any other program to be able to come in and make the pull sheets. A couple things to note the Bin location file changes on a daily basis depending on which BIN the product was put back up into. Looking in "Sample Pull Excel Sheet" you'll see line items 39,40,41, and 43 are highlighted. These line items are highlighted because they are part of an order. Meaning a customer has purchase multiple items from our store in which those items need to be combined for shipment. The multiple item purchases need to be highlighted. The columns also need to prioritize the location column, the UOH column, and the Order # column for the Sample Pull Excel Sheet. "SKU Key Excel Sheet" shows all the products and the items that are pairs. Sometimes a customer will order from one of our listings a pair of headlights. If you view Cell B80 you'll see the SKU 000.001x. The x on the end of the part number indicates a pair. In this case SKUs 0.001 + 0.002 = 000.001x and so forth. Another example would be for cell B90 that reads 000.011x. In this case 0.011 (A90) and 0.012 (A91) = 000.011x (B90). I don't think this is important but some lights the right side is the same as the left side. 2.059 (A194) + 2.059 (A195) = 002.059x (B194). No one Sales order needs to be populated twice on to any pull sheet. Once the order is populated once and printed once for use we don't need it anymore. This is all I can think of if there are any questions or concerns please let me know. Otherwise please offer your suggestions and pricing for the job. The person selected for the job will be contingent upon 2 things pricing and simplicity of the solution. Also please don't auto generate a sales pitch to me those offers will be rejected. Thanks! PS: I've defaulted a fixed price of $100 but feel free to make an offer for more. As long as the proposition is proportional compared to the value it provides I have no issues. I've also attached an excel file with the sheets of what the information looks like.

We’re a fast growing startup based in NYC & San Diego! (launching on August 10th) - We’re a resume search engine for the restaurant/hospitality industry, we help staff some of the largest restaurants and hotels across the US. We are seeking an experienced python developer to support our new software and add new functionality. The stack that we're using: Flask (Python), ElasticSearch, MongoDB, Postgresql, SqlAlchemy, nginx, uWSGI, memcached. Ideally you would have experience or familiarity with this stack. Experience with search engines is a requirement for this job. If you’ve done parsing using NLP, Regex, entity recognition, etc. that would be a huge plus! Knowledge on Javascript is critical. AngularJS and html/css is a plus since it is used as well. Bonus points if you're a full-stack developer, but we really need a rockstar back-end developer! Your job is to make sure things are running smoothly as we acquire customers - e.g. monitoring/fixing bugs, developing new features, ensuring there are no crashes, optimizing speed, etc. Later we’ll be adding a lot more complex projects into the mix to grow our technology! The first project you would take on is to look at the code, study it, and learn what's going on. Then you'll give us a “diagnosis," and evaluate its functionality. Additionally, we'd like to know if it will be ready to scale to thousands of paying clients that are using the tool simultaneously. The second project will be developing a small feature set. If your performance meets our standards we'll discuss keeping you on a long term basis, and with the way we’re growing who knows what can happen! Other must have non-technical requirements: -Must have people skills -Must be open to feedback and not take constructive criticism personally -VERY Detail Oriented -Fast worker & high quality -Clear communicator To apply, answer the questions. Give us a cover letter and if you have a Linkedin/resume, go ahead and include that in the application. Thanks!

hi there, I need modest hybrid (item-based) recommendation engine linking Users to Items in a database, which are mostly crawled with a small portion (<5%) crowdsourced. Marketplace [this is the main focus of the project] 1) User profile entered via i) registration ie preference/survey (item ranking). logged via fb/google accounts; ii) online behaviour [this is not the main focus of the project] 2) Items are classified with many attributes and assumed cleaned and structured. some but most expected to lack rankings by Users. Items are time-sensitive (perish over time) but can still be used for recommendation reference point. -> Match Users with Items. ie predict User's ranking on items

Our Codeigniter application uses PostGreSQL as the primary database And is also connected to a second database using Pervasive SQL via ODBC. 1. For both databases, we need get data from various tables and update each other As an example, we have a customer table in Pervasive that needs to update the same Customer Table in PostGres. If Customer doesn't exist in PostGres, need to insert new record or if customer does exist then update existing record. Second example is we have sales tables in PostGres that need to insert into sales table in Pervasive. Pervasive database is accessible via normal sql insert, update, delete commands. The table structure between both databases is different so need to do some translation. As an example, FirstName is PostGres is called Name in Pervasive. For the various tables in each database and translations between each database, we will assist you in understanding the differences. Question --> How do your propose handling the translations / inserts / updates between the databases ? 2. The database communication needs to happen on a scheduled basis such as every 10 minutes. Question --> What method would you like to use for recurring updates ? 3. If update isn't successful for any reason, needs to handle this without duplicating or missing any data next update. Question --> How would you like to accomplish update errors ? 4. Detailed logging either in database or log file to see history of each update such as date, time, table field, old value, new value, success, error, etc. Question --> How would you like to do the logging ? 5. After each scheduled update, would like an email sent with Success / Failure along with summary of the operation. Question --> How would you like to send notifications ? In your response, the more detail you provide on each question the better. Thank You
