Scrivnr Platform
The video and live link show Scrivnr’s public marketing site, which I helped build at Manafall. It is the public-facing part of a wider software product used by Scrivnr and its clients.
Contribution: I implemented responsive frontend interfaces from the design team’s direction and integrated the site with Strapi so Scrivnr can manage its public content.
My broader work at Manafall also includes Scrivnr’s private internal business-management platform and client portal. Those interfaces and source code are not shown here.
Open-source full-stack application
Legibill
Legibill is an open-source full-stack application for researching and tracking United States legislation, legislators, bill sponsors, history, and legislative progress.
Contribution: I contributed frontend and backend features and diagnosed a major third-party API bottleneck. By redesigning request batching and data-fetching logic, I reduced large response times from more than 60 seconds to under 10 seconds.

Background and perspective
About
I am a frontend-leaning software engineer with production experience building internal tools, client portals, data workflows, and API-driven applications.
At Manafall, a small development agency, I work on Scrivnr’s internal business-management platform, client-facing portal, and public website. Previously, I completed freelance application and integration work and contributed full-stack features and performance improvements to the open-source Legibill project.
Before entering software development, I spent several years living and working in Chengdu, China as an English teacher and freelance recording engineer. When my wife and I decided to move back to the United States, I began studying software engineering and completed Springboard’s 800-hour mentored program.
Outside of software, I produce music, create videos, play Dungeons & Dragons, climb, and spend time with my wife and our four cats.
