<strong>Harness design for long-running application development (28 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Anthropic engineers overcame limitations of AI like context anxiety and poor self-evaluation by implementing multi-agent architectures, including a GAN-inspired generator-evaluator loop. This system used structured feedback, explicit grading criteria, and contextual handoffs (or later, improved model capabilities) to guide AI during long-running development.

<strong>We Rewrote JSONata with AI in a Day, Saved $500K/Year (5 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Reco had large compute costs and latency due to its Go pipeline calling JavaScript JSONata processes over RPC for billions of events. So, they used AI to rewrite JSONata into 'gnata,' a pure-Go implementation, in just seven hours for $400 in tokens. This new solution delivered a 1,000x speedup on common expressions and eliminated $500K/year in expenses.

As AI agents increasingly write code, organizations must develop explicit coding guidelines for consistency and maintainability within enterprise codebases.

True software engineering is not measured by lines of code but by the ability to navigate complexity, manage trade-offs, and apply skills like system thinking and communication under constant constraints

<strong>My minute-by-minute response to the LiteLLM malware attack (18 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
An engineer discovered and responded to a supply chain attack on the LiteLLM PyPI package, which began as a routine investigation into a frozen laptop. Using Claude Code, they quickly identified the malicious `litellm_init.pth` file designed to steal credentials, exfiltrate data, and establish persistence. From the first symptom to public disclosure and reporting to PyPI security and LiteLLM maintainers, the entire incident was resolved in just 72 minutes.

<strong>From skeptic to convert: how Fieldy adopted Expo for their AI wearable (10 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Fieldy (an AI wearable app relying heavily on BLE and background audio) was skeptical of Expo adding overhead, but migrated and cut app size by 25%. The gains came from Expo Atlas-guided bundle cleanup (removing bloated date/calendar libs, fixing lodash tree shaking, and deleting an 18MB bundled SF Pro font), replacing XHR/blob hacks, and fully automating deployments with EAS Workflows.

<strong>Model Collapse Is Already Happening, We Just Pretend It Isn't (6 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Model collapse, where AI models degrade over time, is already happening as new systems are increasingly trained on data generated by previous AI models. This recursive process smooths out rare and diverse patterns, leading to a loss of variance and homogenization in outputs.
