• Developed reusable, modular frontend components with React, Router, and Hooks, managing state through unidirectional data flow to minimize renders for a fluid multi-page application user experience

• Established RESTful API using Express server while performing asynchronous third party API calls/HTTP requests, following the model-viewer-controller (MVC) architecture to enable modification and future scalability of readable code, mitigating errors

• Implemented a Redis caching layer between clients and their AWS Lambda metrics, utilizing the cache aside pattern along with a Time To Live (TTL) value to minimize load times when making successive calls for the same data

• Engineered in TypeScript for robust type-checking with strict type-safe, self-documenting code, benefitting code readability, error handling before runtime compilation, and maintainability of codebase

• Constructed tests using Jest and applied them with Travis CI, leveraging TDD practices and CI/CD to maintain consistent data handling and ensure application functionality throughout product development cycle, leading to time reduction between update releases

• Configured deployment with Docker’s container management system for platform agnosticity, hosted with AWS Elastic Beanstalk for seamless monitoring of load and health checks, reinforcing the app for future scalability

• Adhered to scrum workflow by reinforcing daily stand-ups, along with sprint reviews, to manage deliverables and mitigate blockers from the agile-developed release timeline, resulting in improved codebase consistency and team cohesiveness

• Product developed under tech accelerator OS Labs (opensourcelabs.io)

• Integrated the Express framework in a Node.js environment to efficiently organize routes and seamlessly chain server-side middleware to modularize backend requests, ensuring user experience with RESTful endpoints is handled accurately

• Coupled Github OAuth configuration, which provided a secure and seamless user login experience through authentication tokens, with Github API, which allowed for accurate handling of user profile data, in order to convey compatibility metrics with potential matches

• Constructed unit and integration tests using Jest to reduce runtime errors while ensuring that future updates will require less debugging time for the team

• Engineered an ACID compliant PostgreSQL database with strict schemas for storing user and character information, querying relational data, and sending retrieved data back to the server, ultimately enabling users to access their updated character sheets

• Harnessed the Redux store and Redux hooks to manage over fifty dynamic states, effectively preventing unintended state mutability and side effects, improving future scalability and data consistency
