Joshua Udensi · Senior Product Engineer · Vancouver

Products, platforms, and ideas built with systems discipline.

I am a senior product engineer building products, platforms, and the systems beneath them — analytics surfaces shaped by an LLM, real-time data, and the developer experience underneath. I currently hold a staff role at Opiniion. I write at In Principle. This site is a small, curated home for the work that is worth keeping.

  1. Staff Software Engineer 2026

    Natural-language analytics, and a unified product after acquisition

    Two parallel threads at Opiniion — an LLM workflow that turns plain questions into a query DSL and chart spec, and the architecture that lets two acquired products read as one dashboard.

  2. Technical Team Lead 2025

    Ari, and trunk-based delivery on a customer-facing surface

  3. Senior Software Engineer III 2023

    Migrating the widget platform to TypeScript and React

    A multi-year migration of a customer-embedded widget from a legacy stack to TypeScript + React — taken seriously because it ships into pages we do not control.

Good systems reduce panic

A test for system quality that holds up better than most. If a system reduces the panic of the people who depend on it, it is doing real work.

About

Engineer, writer, retired guitarist.

I work across product and platform — the bridge where a clean technical boundary becomes a calmer human surface. I write short essays at In Principle, and I treat editorial precision as part of the engineering.
