Command in Mobile App Development. I first discovered my passion for Ruby on Rails when I joined my first company, Gammastack Pvt Ltd. Assigned to work on the MyVeeta project, a portal similar to LinkedIn, I found myself working with a team that used five microservices to create a dynamic and complex system. The backend was built on Ruby, while the frontend used AngularJS, and Elasticsearch added another layer of complexity to the project. Working on MyVeeta gave me the opportunity to dive deep into the Rails framework, and I soon discovered a love for designing APIs with Swagger, building out controllers and views, serializer, and working with Active Record. As I gained more experience, I found myself working on even more complex projects, where I was responsible for integrating more than 20 third-party APIs, including Bitbucket, Gitlab, Heroku, Cloudflare, Jira, Trello, Slack, Datadog, Google Cloud Identity, Microsoft, Justworks, and more. I used a range of authentication mechanisms, including OAuth, API key, and API token-based systems. Throughout my 3.5+ years of experience working with Ruby on Rails, I have honed my skills in areas such as background processing using Sidekiq, cronjobs, caching, integrating payment gateways such as stripe, and more. In my most recent work experience, I had the opportunity to work on Edcast, a complex product built with 12+ microservices all running on Ruby on Rails Here I successfully upgraded a legacy application from Rails 2 to Rails 5, reducing the average request processing time by an impressive 78% from 4.5 seconds to just 1 second. Each project has presented new challenges, and I have relished the opportunity to learn and grow with each one.
