follow prototype approach in every web/mobile apps.
Quido(Own MVC framwork with socket-io flavour build on express.js) Exventure (travelling social networking site with real time) uBot (Customer support system in realtime) Realtime (Geo chat) with phonegap.
Custom node modules with npm publish. Node-webkit Knowledge Backend Json based API knowledge with phonegap
node-mysql npm is very fast and very easy to use and gives high performance database manipulation with database pool mechanism.
Reduce the complex code of CRUD operation and create own mechanism Pool mechanism for speedup database and high data availability All queries are Atomicity and Transactions proof.
Not much only session system(session storing mechanism) and set,get,delete variable in redis database.
I have some knowledge of phonegap for building mobiles apps using API provided by phonegap to Building mobile apps.it means i can turn web app to mobile app using some feature of device like filesystem,notification,camera. SPA implement/handling with prototype in every phonegap project. Realtime (Geo chat) with Node.js.
Mongodb the speedup enterprise application,i've developed one system one kind of framework with flexible configuration use both mongo and mysql need little configuration mongo is up and running.
CRUD Operation. Aggregation. Map reduce. Transaction. Concept of Replica Concept of Sharding Complex embeded linking.
The first language i learned in web is PHP and after years of development knowledge i've created php framework(floaty) for mid-large apps with flavour of texture(functionality to convert database rows to final html block using single chunk of comment section(layout of html).
Socket io ,The great realtime library also including streaming services,I learned socket.io just after node.js start to learn,and very good knowledge of socket.io and socket.io.stream for image and video streaming.
Image & Video streaming. Mobile and Web realtime chat. Data manipulation in realtime with server and less overhead of ajax request.
A promise of high Performance web apps and mobile apps deliever,using node.js mysql(with database pool mechanism i have performance /availability mysql test ),mongodb and for small apps redis is there.i will personally guarantee of 30-50% hike of performance with node.js over traditional web development.
I can handle of whole project flow and architecture after all or partial requirement of project is present.and also maintain the project changebility.
If project budget bare the security money then,i can manage SSL security(https) with node.js and also minimal secure web app without SSL using custom encryption technique on request and response of web,so no need to worry.
I have some knowledge of payment integration mostly with (payu money) with node.js
