Work Experience

Full-stack Mentor

2021 - PRESENT
Lighthouse Labs
  • Mentored students on programming concepts throughout the curriculum, providing guidance and support to help them succeed in completing the full-stack boot camp program.
  • Engaged in active reviews of mid and final team projects focused on web application design, helping to complete the project MVP for demos.
  • Provided one-on-one project and code reviews, guiding students towards best practices on software development in both front-end and back-end systems.

Intermediate Full-stack Developer

2021 - PRESENT
PayByPhone
  • Enhanced the existing web application for one of PayByPhone's initiatives and brought their MVP product to a production-ready stage by implementing React best practices in a team of back-end developers primarily working with C#.
  • Oversaw the design of specific front-end epics for the team with documentation and task arrangements in Jira, enabling the development team to do its work and meet deadlines with minor interruptions.
  • Provided training sessions on React development to primarily back-end engineers, which increased the front-end tasks velocity, and improved test coverage and team engagement.
  • Developed portals for corporate client users to track parking costs and their corporate fleets histories, improving cost management, tracking, and reporting for business analysis.

Rival Technologies
  • Developed complex features for specialized marketing tools, enabling market researchers to create dynamic, personalized, and meaningful chat and media-based surveys.
  • Migrated the legacy monolithic back-end system into microservices using event-driven architecture and design for fault-tolerant services and increased the back-end team velocity.
  • Led a team of three developers handling several back-end features in design, architecture, and epic planning. Used Jira tools to support the team in meeting feature development expectations and deadlines.
  • Supported the front-end React team in developing complex components during the migration to TypeScript and GraphQL for an improved version of the chat authoring interface.
Technologies: Amazon Web Services (AWS), React, TypeScript, Node.js, GraphQL, SQL, Amazon DynamoDB, Microservices, Material UI, Redux

Slack Code Review Bot

https://github.com/bert-bae/code-review-bot
An API interface to communicate with slack users using the command pattern to track existing pull requests. The application is a demo to support a possible use case for development teams to track pull request statuses, history of reviewers, and review scores. It was created following discussions on the developers' difficulty in tracking code quality improvements over time, considering past code review scores and trends. By using class interfaces, it is coded in a way that will make it easy to extend functionality to other chat applications such as Teams or Discord.

Flooding

https://github.com/bert-bae/flooding
Flooding is a web application that uses Mapbox GL and a custom layer to showcase the impact of rising water levels. Map highlights show the areas of coastal cities that will be impacted by global warming as glaciers melt and waters rise. Users can interact with the map to see how Vancouver will be affected by rising water levels and expand their knowledge of the possible damages of global warming worldwide. Demo version—flooding.bertcode.com.

Nubrew—Beer Label Recognition

https://github.com/bert-bae/nubrew
As a part of a hackathon project, a partner and I developed Nubrew. It is an application that communicates with Google's machine learning API to provide information on beers based on the image recognition of beer labels. The proof of concept was created using a machine learning model of five beers and hooked up to a React Native application. The user can take a photo of one of these beers for the application to pull up relevant information.

AutoWordle

https://github.com/bert-bae/auto-wordler
Wordle is a popular online game with a lot of daily players. This application is a terminal-based version of the game. By providing input, the application will attempt to decipher the game within six tries by narrowing down possible answers and constructing regular expression patterns after each attempt. Each failed guess will reconstruct the pattern by matching regular expressions based on previously used letters; it follows the same original Wordle game's rules by letting the program know which letters exist in the word or match the exact position.

Webhook Events

https://github.com/bert-bae/bae-webhooks
The webhook event distributor was created as a part of a demo for a possible use case in distributing data across multiple subscribed clients. Using Lerna to package the library with the webhook API service, the application is capable of storing subscribed listeners to events based on ownership criteria. By subscribing to an event, the API's consumption of the event will re-emit those events to the subscribers through the application. A functional integration test is available with instructions on how to run it in the repository README.md.

Starwars Story Crawler

https://github.com/bert-bae/starwars-scroll
The React application was created as a demo using AWS serverless back end to share stories similar to the classic Starwars introductions. The application's back end is currently disabled. However, the web part still works, showcasing functional React programming and less frequently used hooks, such as useRef, to support the animation frames. By changing the story, it's possible to see the web application animation of the story's travel through space. Working demo— star-crawl.bertcode.com.

Notion Clone

https://github.com/bert-bae/notion-clone
A clone of the Notion-enriched text editor using React. The project is a demo within another project released as an MVP to support rich text editors. It uses React with support for bold and font type editing and slash commands to build text nodes. It is a pure front-end implementation of the MVP.
