Rockstar🎓
Top SchoolJustin Le is a Principal Software Engineer with 12 years of experience building high-assurance, performant systems at the intersection of data science, machine learning, and physics. He combines a PhD-level background in computational and data sciences with hands-on expertise in Haskell and large-scale analytics to deliver statically verifiable, maintainable pipelines and models across domains including climate, energy, finance, and defense. Justin has shipped production infrastructure at Google and Anduril, led large Haskell backend efforts at SimSpace, and contributed to well-regarded open-source projects such as hledger by adding market-value reporting features. He focuses not just on prediction but on building full mathematical and data-driven frameworks that make systems interpretable and auditable over the long term. Based in California, he is equally comfortable deriving stochastic models and implementing robust, extensible software to operationalize them.

Contributions summary:Justin primarily contributed to enhancing the functionality of the hledger accounting tool. Their work focused on adding a `--value` option across several commands, including balancesheet, incomestatement, cashflow, and register. This involved modifications to existing Haskell code, specifically within the CLI and reporting modules, to incorporate market value calculations. Furthermore, the user implemented a `showMarketPrice` function and added the `Hledger.Data.MarketPrice` module.
