Business Graphics Data Extraction System 2025

Python
RESTful API
Vizrt
AWS

A real-time financial data pipeline for TVNZ's Breakfast morning show.

The Business Data Extraction System is a real-time financial data pipeline built for TVNZ's Breakfast morning show. It serves as the critical infrastructure that powers live financial graphics during the broadcast, ensuring viewers receive up-to-the-minute stock and foreign-exchange information.

The application ingests stock and foreign-exchange data from a third-party provider via REST API, normalizes and validates the payload, and publishes structured updates over WebSocket to a Vizrt Viz graphics engine. This architecture enables seamless data flow from external sources directly into the broadcast graphics system.

The system automates the end-to-end flow—from external data acquisition to graphics-layer integration—enabling live, latency-sensitive financial information to be rendered on-air during broadcast. By eliminating manual intervention, it ensures accuracy and timeliness for time-critical financial reporting.

Kodia/JDA DTT Outages Dashboard 2024

Power BI
Data Analytics
Dashboard
DTT

A data analytics dashboard for analyzing and visualizing DTT outage reports from Kodia and JDA company.

The Kodia/JDA DTT Outages Dashboard processes and analyzes outage reports from both Kodia and JDA company. Kodia and JDA digital terrestrial television systems provide centralized visibility into service disruptions for operations teams. The workflow involves cleaning and normalizing raw outage data from both systems, then using Power BI to calculate key metrics including outage frequency, duration, affected regions, and root cause distributions.

The interactive dashboard visualizes outage metrics through charts and time-series analysis, comparing them against the contracted targets. It enables operational teams to drill down into specific time periods, regions, and outage types, supporting accurate diagnosis and forward-looking planning.

Field Recording 2022

Publishing
Facilitation
Knowledge

A field recording project exploring hidden soundscapes and the quiet details of everyday environments.

Field recording is an ongoing practice of capturing the acoustic textures of places—the layers of sound that define a moment, a location, a memory. Through careful listening and documentation, these recordings reveal hidden soundscapes that often go unnoticed in daily life.

Each recording becomes a time capsule, preserving not just the sounds themselves but the context and atmosphere of a specific place and time. The quiet details of everyday environments—the hum of machinery, the rhythm of footsteps, the distant conversations—form a sonic map of lived experience.

This project explores how field recordings can function as both documentation and composition, where the act of listening becomes a form of storytelling. By focusing on the subtle and overlooked, these recordings invite deeper attention to the acoustic world around us.

Ksana Radio 2016–2021

Podcast
Electronic Music

A long-form music commentary podcast tracing the textures of electronic sound and diaspora narratives from Auckland, New Zealand.

Ksana Radio is a mixtape journal I produced and hosted between 2016 and 2021. Each episode layers interviews, field recordings, and electronic selections to map how sound shapes memory while living thousands of miles from home.

The show follows a loose ritual: open with meditative textures, travel through club experiments, then land in conversations about diasporic imagination. It's part archival practice, part personal radio transmission.
