Joshua Burke

Senior software engineer and independent consultant based in Vermont.

I build and maintain production web applications, data and reporting platforms, APIs, and operational systems.

My current focus is Elixir/Phoenix, Rust, Go, and reliable software delivery: understanding established codebases, modernizing dependencies, improving testing and observability, and delivering features without destabilizing production.

Current work

Conductor — an Elixir/OTP implementation of the Symphony service specification. It integrates Linear and Codex, creates isolated per-issue workspaces, coordinates concurrent workers, and exposes a Phoenix LiveView operations dashboard.
Independent consulting — software maintenance, modernization, architecture, automation, and incremental full-stack feature development.

Observability

My professional background includes public-safety platforms, renewable-energy telemetry and reporting, predictive analytics, e-commerce, and internal education systems. Earlier field-operations work included LiDAR scanning, real-time weather instrumentation, geospatial data, and high-frequency telemetry.
