Current focus

I build robust backend systems, data reconciliation workflows, and practical analytics software designed for reliability, data integrity, and rigorous testing.

01

Backend systems

Java/Spring Boot applications with authentication, database-backed workflows, Docker, and integration tests.

02

Data reconciliation

Python and pandas pipelines for messy exports, indexed candidate matching, and review queues.

03

Analytics tools

Python, pandas, and Streamlit dashboards for data cleaning, segmentation, and reporting.

Projects

TransparencyBC search interface static screenshot Case Study

TransparencyBC

Search platform for British Columbia FOI releases, OIPC orders, and judicial reviews. Built with a decoupled Python (Flask) search API, chunked Typesense indexing, and signed PDF document streaming.

  • Commercial subscription application; architecture walkthrough and static screenshots from the project are presented in an open case study requiring no account
  • Chunk-based Typesense search across indexed records with signed PDF streaming to a browser viewer

Useful work, real problems.

I like building software that makes real work easier: cleaning data, connecting systems, making things searchable, and turning repeated tasks into tools.
