Michael H — Web Development freelancer in Simi Valley

For this project, I was entrusted with the responsibility of completing a web application initially set in motion by a previous engineering team. The technologies involved were React.js and Node.js, and the unfinished aspects of the project included implementing payment integration, finalizing the client onboarding flow, and addressing various other crucial elements that stood between the application and its launch. As the solo engineer on this project, I embraced the responsibility wholeheartedly, committing to round-the-clock availability for bug fixes following the successful roll-out of the application. My unwavering dedication coupled with my demonstrated expertise in coding earned me the trust and confidence of both the CTO and the company owner. Next, I was handed the challenge of transforming this web application into a cross-platform application compatible with iOS and Android, using React Native. The reimagined application featured integration with Google\u002FApple Maps to help users locate related stores in their vicinity. The application allows users to opt for a monthly membership, managed via NMI. Subscriptions can be altered anytime, with the NMI charges being adjusted accordingly. The application's backend, written in Node.js, was hosted on an AWS EC2 instance. A Node.js-based task-runner was developed to handle several financial transactions and execute cleanup functions. Scheduled via CRON, the task-runner operates during non-business hours. The solution incorporates Cognito for authentication and authorization, ensuring every new user's phone number is verified. Billing was automated, with NMI handling monthly charges and my task-runner managing re-charges. Salesforce serves as the database for this application, with JsForce being utilized to interface with the Salesforce API. This project showcases my abilities in full-stack development, app transformation, and efficient automation, ensuring both robust functionality and streamlined user experience.
