Sri Lanka - Tests: 20 - Portfolio: 9

Hello, I am Ziyan a computer engineer currently a inventor, freelance developer, entrepreneur from Colombo Sri Lanka. 15 years ago I discovered the joy coding by accident. Today not a single day passes by without me solving problems. I started schooling at St. Anne's College. Then attended University of Peradeniya Faculty of Engineering for my higher studies and passed out with a BSc. (Eng) in Computer Science in 2012. Considering work, I briefly worked as a network engineer (6 months) and a systems engineer (6 months) in my interest to get a complete picture of IT infrastructure. Today I work full-time as a full-stack web developer. I love what I do and in fact coding is a hobby. I am also kind of a perfectionist with high regard to quality and believe engineering is art. I am on the continuous search for the best tools & technologies in the market to build future proof cutting edge efficient and effective solution. I prefer to work on Ruby on Rails projects regardless of their scale let them be simple websites, e-commerce, custom applications or multi-tenant SASS suites. I also do Android app development and hoping to expand to Apple and Windows Phone app development. Services ---------- - Advice / Consultancy - Web sites - Web applications - E commerce stores - Feature extensions - Maintenance Languages & frameworks ------------------------------- - Ruby (Ruby on Rails, Sinatra) - PHP (Laravel, WordPress) - Python (Django, Flask) - Java (Spring, Android) Preferred stack (new projects) ------------------------------------- - Rails 4+ - Active Record + PostgreSQL - Squeel for complex but neat queries - Slim template - CoffeeScript (OOP) + React.js - Sass - RSpec - Cucumber Current involvements -------------------------- I am engaged with few projects on UpWork. Most of which are Rails projects of sorts e-commerce and SAAS. Other than that I am working heavily on the first release of DCommerce, a free e-commerce suite based on Ruby on Rails targeting the local (Sri Lankan) business community. That is my way of saying "thank you" for the free-education I received. I am also in talks with a friend to start up a payment gateway that will work in compliance with Sri Lankan Central Bank policies to bring safe and secure e-commerce to Sri Lanka.
