Part-time Agent Task Designer
2025–Present
I currently do part-time work on DataAnnotation.tech designing tasks and evaluation criteria primarily for coding agents.
Weston Beecroft
AI Product Engineer
I'm a software engineer with experience across early and mid-stage startup roles, independent entrepreneurial work, and consulting engagements. I've specialized in application architecture, interaction and UI design, LLM systems design, and product development. I'm comfortable working in unexplored territory without established patterns. I love bringing new ideas and products to life, and enjoy working with small teams. Since early 2024, I've focused on designing and building AI systems while refining my development practice to effectively leverage coding agents.
Professional Experience
Software Engineering, Research, and Design Consulting
2017–2025
- Conducted research and developed a memory and task-dispatch architecture for an agentic coding system.
- Built the initial platform and features for a browser-based CAD application for Big Ass Fans. Developed algorithms and interaction designs that eliminated the need for sales staff to be paired with engineering support, and helped onboard additional developers as the team grew.
- Served as front-end lead for an AI job-finding and applicant-tracking startup (Cardinal Talent), building the initial React application and managing a small team of additional contracted developers.
- Built web applications across domains from radiology to 3D product customization using React, TypeScript, three.js, Node.js, and Express.
- Researched classification and reconstruction methods for urban LiDAR point clouds and built a classifier (https://www.youtube.com/watch?v=YFHFlfjKxHM).
Voxel8 (3D printer startup)
Cambridge, Massachusetts
September 2015–October 2016
- Built the web-based front end for the printer's user-facing web app, including a 3D print designer (three.js).
- Built the execution architecture of a simulator of the printer, and worked with an intern to develop its rendering and UI.
- Collaborated with scientists and engineers to refine app designs and build internal tools.
- Helped on the backend (Ruby on Rails).
Binary Thumb (Y Combinator startup)
San Francisco, California
March 2013–August 2014
- Was the first engineering hire (simultaneously with one other person).
- Developed the engine/platform for an iOS app with novel UI, complex interaction patterns, and multi-user collaboration.
- The version built by myself and two others was featured by Apple in the App Store.
- Participated in product design, user testing, and hiring.
Independent Research and Product Development
-
Designed and built a Rust-based LLM/agent workflow-graph executor with structured working memory, a dynamic prompt-construction system, resumable execution, and a web front end with a built-in workflow editor (early project doc: https://symbolflux.com/working-group-foundations.html; editor demo: https://x.com/Westoncb/status/2058315559272599975).
2025–2026 -
Designed and built a system for structured, live/in-place updating, queryable “print debugging,” including a custom query language (https://www.youtube.com/watch?v=FG5LeC-3n5w).
2023 -
Developed a cross-platform disk scan product (https://diskatlas.com/).
2021–2022 -
Designed and built a “structural” code editor in Java and OpenGL designed for efficient use with motion sensors (https://www.youtube.com/watch?v=tztmgCcZaM4).
2011–2012 -
Designed and built a visual data-structure debugger to aid the development of the runtime for a Prolog-like agentic AI system (https://www.youtube.com/watch?v=KwZmAgAuIkY).
2014–2016
