Augmented Development: FastDecimal Unleashed

Andy Bailey dives into FastDecimal, a DIY, performance-tuned alternative to Java’s BigDecimal that uses a 4-scale long for snappier financial math and SIMD-friendly ops. To level up, he ropes in AI agents like ChatGPT, Claude, Gemini and Junie to write code, back it up with JUnit tests and JMH benchmarks, and push the limits of what “augmented development” can do.

In his talk you’ll get the full play-by-play: the slick wins, the head-scratching surprises and the “oops” moments that didn’t pan out. If time allows, Andy might even live-code (or live-prompt) onstage and field your burning questions.
