Fixed-Price - Est. Budget: $ 5 Posted
I am part of a team that is working on a port of an existing browser game (www.cs-manager.com) to a new technology stack (as well as creating mobile versions of the game). For this undertaking we are looking for developers who would like to join. Here is some insight into what we are looking for: CS-Manager is a complex game which enables managing a Counter Strike (ego-shooter) clan as well as simulating games etc. The current code base is quite old and we want to create something even better. Our current technology stack contains a mix of different technologies. The front end is using mostly PHP and some parts are HTML and JavaScript as well as Java. The back end is written in C and the database is a PostgreSQL database. We are using a bunch of modern tools to help organize and structure our work. Those include JIRA, Confluence, Stash and Slack. We are planning to move to a more simpler technology stack with the new version of CS-Manager. Our plans are using JavaScript...

Have an existing ROR PoC application that I need to make awesome. Do you have the skills to make this happen? 1) Will need to take the existing site (9 interfaces) and bedazzle it with awesomeness - transforming the ordinary CSS/HTML into something beautiful to behold! 2) Will need to implement PayPal integration so I can get rid of the freeloaders and start charging a subscription to access the service. - Basically while their subscription is active (will need to check if it still is active on first login), they will have access to everything. - If their subscription has expired, they can see everything but can't search or submit. 3) Implement email. When the user clicks the submit button, it needs to send an email (let the user determine the body content but pre-populated with a default message) to an email address specified in the object model. 4) Has a few minor feature implementations that will need to be done (showing more fields of a model on a view, change object ordering...

We are looking for a nodejs developer to aid in translation of our current Redis-only data storage to Postgres+Redis. We have a social-network style application with growing number of users. Our task is to migrate data from redis data store to a relational database (PostgreSQL). The task involves: * extracting Redis-specific code from everywhere in the application to data access layer * writing and testing a script to extract Redis data and properly insert it into Postgres database schema. * updating data access layer to use Postgres as storage and Redis as cache * performance evaluation and tuning The platform itself is open-source and you will be working with its developers on github. Required knowledge: * async/await/promises knowledge is a must * bookshelf/redis knowledge is a must * ES7 and babel/flow is a plus

We’re doing a migration of time-series data from PostgreSQL to Druid — Druid requires Hadoop processing and we are slowed down because we have no experience with Hadoop. We are under a tight deadline and are looking for someone who can help us with the implementation of Hadoop processing for our Druid cluster. Prior experience with Hadoop is required; familiarity with druid is a plus, but not required. --- We reach 3.2 million academic researchers per month and are growing 14% per week -- we provide the 'Recommended links' widget found in thousands of academic research journals. We're looking for a Hadoop Expert: 1) Work is remote (your location doesn't matter) 2) Schedule is flexible (part-time or full-time) 3) About our technology stack: Fabric, Git, Ruby on Rails (web app), Python (machine learning) Node.js (crawling), PostgreSQL, Solr, ElasticSearch, Druid About us: 1) We are profitable and growing fast 2) We're based in New York and Toronto (everyone works...

First of all, I am a seasoned C++ developer with good knowledge of SQL, so you will be dealing with a professional. I need help with anything that has to do with UI, unfortunately. This project involves users viewing certain assets and posting bids Administrative backend needs to be able to manage these assets, user accounts, orders and transactions. Everything should be kept simple and minimalistic, with perhaps some AJAX / JavaScript for responsiveness. Quality of code is very important to me, since chances are this application will need to interface with a few other modules. Backend (business logic) will be exposed via Postgres functions. It's a one time project that may turn into an ongoing relationship.
