Dynamic predictions for longitudinal and time-to-event outcomes have become a versatile tool in precision medicine. Our work is motivated by the application of dynamic predictions in the decision-making process for primary biliary cholangitis patients. For these patients, serial biomarker measurements (e.g., bilirubin and alkaline phosphatase levels) are routinely collected to inform treating physicians of the risk of liver failure and guide clinical decision-making. Two popular statistical approaches to derive dynamic predictions are joint modelling and landmarking. However, recently, […]

Before the acceleration of AI, insider risk always centered on human intent. Security teams monitored high-risk employees who were prone to downloading files before leaving the company, or negligent employees who engaged in thoughtless behavior (e.g., clicking a phishing link.) In other words, the insider risk threat model was based on people doing things they shouldn’t. AI has fundamentally changed this paradigm. The risk is no longer limited to ill-intentioned employees but also to those who wish to […]

If you’ve ever built a data pipeline for analytics or business intelligence, you know the basics — ingest, transform, store. But regulated industries are a different game entirely. A missed record in a BI pipeline means a slightly off dashboard. A missed record in a compliance pipeline means a regulatory fine, a failed audit, or worse. Over the past couple of years, I’ve been designing and running ETL pipelines that process over 500,000 compliance data files every month […]

Compound AI systems promise capabilities beyond those of individual models, yet their success depends critically on effective orchestration. Existing routing approaches face two limitations: (1) input-level routers make coarse query-level decisions that ignore evolving task requirements; (2) RL-trained orchestrators are expensive to adapt and often suffer from routing collapse, repeatedly invoking one strong but costly option in multi-turn scenarios. We introduce SkillOrchestra, a framework for skill-aware orchestration. Instead of directly learning a routing policy end-to-end, SkillOrchestra learns fine-grained […]

The pattern is becoming familiar across the industry. Teams build impressive AI agent demos, often coding copilots, research assistants, or internal automation tools. Leadership gets excited. Resources get allocated. Expectations rise. Six months later, the project is either quietly shelved or operating with so much human oversight that it would have been faster to build a traditional workflow. What makes this frustrating is that the teams involved are rarely inexperienced. The engineers are competent. The models are capable. […]

What Are Stablecoins and Why Do We Need Them? The Volatility Problem Bitcoin can gain or lose 10% of its value in a single day. Ethereum swings wildly with market sentiment. This volatility makes cryptocurrencies excellent for speculation but terrible for: Daily transactions Store of value Salary payments Savings accounts Anything requiring price stability The problem: If you’re paid in Bitcoin on Monday, by Friday your salary could be worth 20% less—or 20% more. That’s not money, that’s […]

I wrote the original version of this list in 2018, just weeks after trading my graduation cap for a corporate badge. Back then, my biggest shock was realizing there’s no “Spring Break”! Now, as a Senior Engineer who has navigated Amazon, Microsoft and Salesforce, I’ve realized those early shocks weren’t just “adulting” milestones. They were foundational lessons for a long-term engineering career. Here’s the 2026 “senior-level” retrospective on what I learned at my first job. 1. From “No […]
