Work Experience
Software Advisor
2024 - PRESENT
Tame
- Implemented a consistent design system and structure for the project, building several modules, including execution, allocation, and market data. The system design was to fit the needs of the companies' trading strategies.
- Launched the first strategy on the new design system; it has traded successfully for over one month now and has clear reporting built in.
- Improved the overall developer experience of the project by cleaning up the codebase to leverage various best practices.

Mobile Team Lead
2022 - 2024
Status
- Led a team of 10 developers to deliver an Ethereum Client wallet. The mobile team was struggling to deliver before I took over the leadership role. At that time, I established processes to improve the quality and accuracy of delivery.
- Added a range of automated testing tools to the project, this became a big help as the size of the team increased.
- Improved the organization of the codebase drastically to allow for easier development and maintenance of the application.
- Improved the quality of implementation of the new design system by bringing in development processes.

Founder and Lead Developer
2022 - 2023
123NFT
- Acquired a partnership for sales and marketing to pitch this website for further investment across China, the United States, and Europe.
- Implemented the website with a microservices architecture. This involves an orders management back end built with Node.js and Express.js and an order processing back end built with Python and Flask.
- Deployed a live application that uses Python3. The application was deployed using Heroku and is a WSGI application.
- Worked with a garbage collector, multi-threading, and task queuing in Python 3. The order processing back end handles computationally expensive photos, so this process had to be streamlined to make it work efficiently.
- Hired the first employees for the project UX and features. To speed up the delivery time, I brought some contractors in to help meet the deadlines and give a broader vision to the project.

Senior Software Engineer
2018 - 2021
Guidewire
- Researched, designed, and implemented a command-line tool that would automatically upgrade users' current versions of our software to the latest version of our products. This included tools to safe guard that best practices are followed.
- Created an automatic visual test suite. This used prop types of React Components to generate a JSON data set of all possible permutations of configurations for props of a component. The test renders each permutation and uses this in the visual test.
- Worked directly with the project architect in product management designing npm packages. I then communicated the packages' design for my team to implement in code.
- Received a double promotion, something unprecedented in Guidewire until then. The company policy only allows engineers to jump one level on each promotion. In 2020 I went from software engineer II to senior software engineer after the CEO's approval.
- Won the companywide internal hackathon. In 2020, Guidewire held a hackathon across offices internationally. My idea and team won this hackathon, and afterward, Guidewire continued to work on this project as a product for their customers.

Front-end Developer
2018 - 2019
FotoStore
- Implemented a responsive web app using Node.js and a React Redux framework. Additionally, Redux-Saga was used for asynchronous behavior.
- Communicated with graphic designers in the company and provided feedback from a software developer's perspective.
- Created and implemented best practices to add some consistency to the project's codebase and development lifecycle. This included conventional commits, lining, and project folder structure.
- Mentored some interns, helping them onboard and guiding them through their daily tasks while getting settled in with their work.
- Interviewed candidates to work for FotoStore. I contributed to the interview process of FotoStore by screening potential candidates and performing technical interviews to later-stage candidates.
