Daniel Sims

Full Stack Software Engineer, JavaScript / TypeScript

Summary

I'm a full stack engineer with a design background, and I love building software that feels great to use. I'm building AI products as a solo founder, owning the work from product definition and interaction design through architecture, implementation and shipping. Before that I led a small team on Oracle's field service product, and spent years in Neto's ecommerce developer ecosystem helping partners build on the platform.

Experience

Founder

Jun 2025 – Present

Latent Supply

  • Founded Latent Supply, independently taking software products from problem selection and interaction design through architecture, implementation, deployment and iteration.
  • Built Chief, a cross-platform workspace for proactive agents, where local and cloud agents collaborate in shared channels, run scheduled work and use external tools.
  • Built Browser UI, an open-source interface and protocol layer for agent-operated browsers, with packages for React and React Native, Flutter and Swift, covering live streaming, recordings, remote sessions and authenticated control.
  • Built Program, an agentic video creation product with agent-driven editing and a programmatic rendering pipeline, plus Hyperfocus, a keyboard-first email client, and Drops for social automation.
  • Work directly across agent orchestration, tool calling, model APIs, authentication, databases, desktop and mobile clients, and interaction design.

Software Engineer, Technical Lead

Jan 2024 – Feb 2025

Oracle

  • Led a three-engineer team building NetSuite Field Service Management after Oracle acquired Next Technik, working primarily in React and Redux on a production application used by field technicians.
  • Owned engineering execution across product initiatives, including breaking down work, sprint planning, implementation, code review and coordinating delivery with product and design.
  • Migrated the product's mapping implementation from Google Maps to an Oracle-owned provider, removing a significant recurring external service cost.
  • Introduced Storybook and documented the design system, giving engineering and design a shared implementation reference and making interface inconsistencies easier to identify.
  • Standardised ESLint and Prettier across the codebase, removing formatting work from code review and establishing consistent automated conventions.

Software Engineer

Jul 2022 – Jan 2024

Next Technik

  • Built product features across the React application behind Next Service, a field service management platform for NetSuite customers.
  • Rebuilt core product screens and their underlying component architecture as part of a major interface overhaul.
  • Improved the shared component library and design-system implementation so new product work remained consistent as the application evolved.
  • Worked closely with product managers and designers to turn operational workflows into shipped, tested interfaces in a team of three to five engineers.

Developer Support Specialist

2021 – 2022

Neto

  • Worked directly with e-commerce technology partners to design and launch applications against Neto's platform APIs, including OAuth integration, testing, troubleshooting and add-on store releases.
  • Ran technical sessions with partner engineering teams and helped developers move from initial integration through to production.
  • Owned the theme store repository, developer review process and developer and API documentation used by e-commerce partners.
  • Built and maintained commercial themes including Oslo and B2B for Neto's official theme store.
  • Performed production MySQL restores during merchant incidents and worked directly with live customer data and storefront systems.

Application & Partner Support

2018 – 2021

Neto

  • Became the support team's specialist for storefront and front-end problems, diagnosing issues across live e-commerce sites, integrations, HTML, CSS and template code.
  • Installed integrations and repaired merchant storefronts while supporting customers directly across phone, chat and email.
  • Developed an early understanding of product usability from working directly with users when software failed, behaved unexpectedly or did not match their workflow.
