Lot of experience working Ruby on Rails. In the past 5 years, I position myself as consult for startups that need to grow to the next level. I go in and I help refactor the code made usually by junior developers and I help implementing best practices. I particularly help organizing projects that started small and ended up growing way too big. Organizing large projects in Rails might be a challenge, since its default architecture and conventions are thought for small projects. I I can help your wit any question you might have with Rails, how to organize large portions of code (controller, model, helper, etc.), so it does not drive you crazy and that is code that is a pleasure to work with. Also, I can help implementing best practices and procedures for a better and clean coding.

As a Senior Software Engineer on the Web Infrastructure team at Taskrabbit, I collaborated closely with a pod of six engineers to develop and maintain robust web applications. My primary focus was on building and enhancing the front-end components using React within the Next.js framework. Additionally, I took ownership of various testing responsibilities, including the development of Jest tests for React components and Playwright End-to-End (E2E) tests. Some of the modules I worked with at TaskRabbit are: Payments, Booking, Profile.
Key Responsibilities:
Front-end Development: Designed and implemented responsive and interactive front-end components using React, ensuring high-quality user experiences and seamless integration with Next.js.
Testing and Quality Assurance: Developed comprehensive Jest test suites to ensure the stability and reliability of React components. Additionally, I leveraged Playwright to design and implement E2E tests, covering critical user workflows and scenarios.
API Development: Utilizing Ruby on Rails, I played an active role in designing and developing RESTful API endpoints to facilitate seamless communication between the front-end and back-end systems. This included implementing efficient data retrieval and manipulation mechanisms.
Migration to React: Led the migration process of existing JavaScript components to React, leveraging modern patterns and best practices. This involved refactoring code, optimizing performance, and ensuring backward compatibility.

Developed an application for collecting ad selling user information for major. All in the same request. The application was being hit by 1K request per second and it had to return in no more than 100ms. Major website (like New York Times) were implementing our code for selling and buying other users data. We were collecting and processing the data with hadoop and then making the data available in a large memcache cluster. Everythings was running in Amazon web service and the application was fault tolerant.
