Ideas Implemented

India - Last active: 16 days ago - Tests: 2 - Portfolio: 3

I have a firm grasp on the structure of a web application , from the architectural level to the implementation level . I have expertise in python as well as php ,two of the most popular languages used for server side programming. I believe in writing object oriented modular programs with emphasis on extensibility and scalability . When developing web applications from scratch Zend framework is my framework of choice for php , while Django is my go-to framework for the python programming language. Both of them renowned to be the most modular and flexible frameworks with focus on object oriented architecture and advanced design patterns for their respective languages. A database forms the foundation of any web application where the choice of application has a deep impact on the performance of our application . A relational database provides us with the ability to make infinite variations of queries and is suitable for majority of projects .Some web applications where horizontal scalability is of concern respond better to no-sql systems which allow for much more flexible representation of data and yield themselves to horizontal scalability better while restricting the type of queries that can be made. I prefer to use a combination of both these types of database with Mysql being my choice of relational database while mongo-db being my preferred no-sql database . My table structure in a relational database is thoroughly normalised minimizing the number of joins required while my no-sql datastore is designed to provide maximum flexibility for querying of data. I also prefer to introduce a caching layer, generally in form of memcached , between the application and database to minimize the total database hits. I design the front-end of my web-application using html 5 and css 3 which allow me to utilize the latest features present in the modern web browsers while ensuring that older web-browsers are adequately supported. I have a firm grasp on javascript and jquery which allow me to design highly interactive user experience . I also have knowledge and understanding of algorithms including sort –search algorithms , graph algorithms .I strive to ensure that problems I face are saved in the most efficient manner possible keeping time and space complexities in check. I am also a very good reader and am constantly updating myself with upcoming technologies and programming models . So I can catch up to any new libraries and technologies fairly quickly. Estimating requirements regarding a software project require experience and I particularly pride myself in my ability to do so efficiently . Hence you can rest assured that any timelines mutually agreed upon will be met at all times. Proper communication absolutely critical for any software project , particularly when the parties involved may be on opposite sides of the world. I believe in keeping my clients in the loop at all times ,keeping them appraised regarding the progress of their project . You may rest assured that with me as your partner all communication channels will always be open and all inputs from you will be taken into account. While I may be new on the freelancing scene , I do have 4 years of experience as a software developer. I would now like to build a reputation and career as freelance programmer. I prefer the fixed priced model of software development as it gives both parties a clear picture of the costs involved in a project , but should you wish I can work out an hourly model as well.
