    With over 12 years of software engineering experience, my focus has been on Elixir and Ruby on Rails. Currently, I hold a lead engineer position at a California-based card processing company, similar to Stripe. My expertise extends to various areas, including new projects, bug fixes, optimizations, third-party integrations, and UI improvements. What sets me apart is my 7-year history in the payment industry, both within and outside of UpWork. This unique experience allows me to provide valuable insights and advice to high-risk merchants, offering them alternative options to Stripe. I graduated from the University of Peradeniya's Faculty of Computer Engineering in 2012. While my freelance history precedes my graduation, freelancing has become my full-time occupation since. In my early days, I worked with numerous e-commerce and CMS platforms. Seven years ago, I joined GivingFire, a US-based payments gateway for charitable organizations. 2 years ago, I joined Edge Payments Technologies, a US-based payment gateway specialized in businesses deemed high risk by card networks and most payment gateways, including Stripe. One of the most significant shifts in my career has been my embrace of functional programming. This transition, while it may sound like a cliché, has truly revolutionized the way I approach software development. As the complexity of the apps I maintain increased, I discovered how functional programming and pattern matching can simplify even the most intricate tasks, often eliminating the need for third-party libraries like Trailblazer (Ruby). I can help you or your organization build and maintain Elixir and Rails-based applications, APIs, and other web-based tools. Preferred Ruby on Rails stack: - Rails (edge) - PostgreSQL - Sidekiq for jobs, AASM for state management - ERB, Tailwind (or Slim with Sass) - Stimulus, Alpine Phoenix Elixir - LiveView - PostgreSQL - Oban for jobs, Pattern matching for state transitions - ERB, Tailwind - Alpine (alongside LiveView Hooks) Looking forward to working together.
