    Saurabh S. Agency Contractor

    Web components / Web / Mobile Developer

    India - Last active: 1 day ago - Tests: 7 - Portfolio: 8

    Specialise in design as well technical implementation of web and mobile based solutions. Work heavily on Javascript, Java along with Python. Keen to work on Web components driven jobs(Love Polymer, React + Flux Architecture ). Love working on newer HTML5 features. I am a 11+years experienced developer. I have worked for more than 3-4 international solution providers before starting my freelancing career. Right now I am looking for a new Contract after doing one for a single long term contract. My profile can be viewed at in.linkedin.com/in/saurshaz A few bit about the work culture and commandments i believe in are below - # Documented API design using Swagger and automated validation tools. # High focus of Test Driven Development (TDD). More importance on testing than implementation itself (E2E as well as Unit testing) # Heavily maintainable codebase/solution with clean and commented code. We do not compromise on quality at any stage. # Also rely a lot on continuous integration tools for being in control of the situation at all points pre-post implementation of the project # Work with the client in an agile methodology, Deliver a stage build to the client on heroku /AWS at suitable times and keep the client engaged for inputs along the way with communication channels(Skype/hangouts etc.) # Follow a lean but powerful tech stack(For Node - MEAN or Mean minus A plus X MVVM f/w or React based isomorphic code, For Java / Python - Flask/ mysql/mongo, For- thin server , richer clients). Open to adapting more and more on this and learning along the way as different requirements are faced. # Defect management in simplest manner # Initially scope of work via easiest and quickest way of documentation) Modules based UI development like done in Polymer/React along with REST APIs are the areas that I'm currently exploring. The github/bitbucket repo - https://github.com/saurshaz, https://github.com/ProKriya, https://gitlab.com/saurshaz and https://bitbucket.com/saurshaz. Most of the work though is in private repositories on bitbucket. Some of the recently worked upon applications - * A public facing alumni based job portal -- letscatchup.net. Involves a job aggregators switch-ability with ease using a written-from-scratch framework * The current project which is a platform built on isomorphism of JS on browser and node world * Polymer based UI talking to REST calls, Documented with Swagger * Flux architecture e-store with APIs interaction http://about.me/saurshaz ~Saurabh
