Portfolio Project
August 2022
Svelte
Typescript
Tailwind
UI/UX
Genetic Algorithms
A reforestation simulator prototype that uses genetic algorithms to find optimal tree planting scenarios that maximize both carbon sequestration and biodiversity. Hand-built with SvelteKit, Tailwind, and multithreaded web workers.
This app plants different mixtures of temperate tree species on one acre of land, and then simulates 100 years of tree growth and self-seeding by calculating the sunlight available to each tree, with optional selective harvesting.
The goal is to find the initial makeup of tree species, and the frequency of harvesting, that leads to the highest sequestered carbon and biodiversity.
It runs multiple scenarios in parallel using multithreaded web workers, evolves successive generations using crossover and mutation, and stops after 20 generations.

GraphQL
Gatsby
Tailwind
Cypress
UI/UX
- Developed frontend of energy decarbonization web application using React, Gatsby, Tailwind, Typescript, and Cypress
- Brought frontend from rough alpha prototype to sleek, polished beta

Other responsibilities:
- Peformed code review of team members' pull requests to the frontend codebase
- Developed rapid UI mockups to present to research team
- Implemented end-to-end tests in Cypress to flag breaking changes before they got to the review team
- Worked with backend development team to develop APIs and schemata, and to integrate new analytical models into the UI
- Refactored existing brownfield codebase to reduce code duplication and bug potential, and streamline development
- Implemented Redux-style and atomic state manager patterns to speed up debugging and development, and eliminate race conditions
- Debugged and improved app rendering performance issues, stemming from multiple concurrent and overlapping API requests driving chart updates with large datasets, using custom equality functions and context instead of prop drilling
- Researched deployment scale-up options and presented a detailed feature matrix to the Head of Product
- Debugged and fixed AWS CodePipeline build errors and managed staging and production deployments
