LeetCode practice is often slowed down by the same problem: you know the code runs, but you do not really see how the variables move. I built a browser-based solution visualizer to make that execution trace easier to inspect, replay, and understand.

MIT's EnergAIzer looks modest at first glance: a faster way to estimate GPU power. But that small shift matters because AI efficiency is increasingly becoming a scheduling and capacity-planning problem, not just a research talking point.
TurboQuant is one of the more interesting efficiency ideas from this cycle because it targets a real bottleneck: KV-cache memory. The innovation is real. The practical benefit also looks real. But the value is clearest in long-context, memory-bound workloads rather than as a universal compression miracle.
PostgreSQL is still treated like 'just the database,' even though it can absorb surprising amounts of search, scheduling, vector, auth-adjacent, and API work. OpenAI's own PostgreSQL scaling story is a good reminder: this tool has far more headroom than most teams assume.

Building CoreLink AI: An Evidence-Grounded Reasoning Engine That Knows When to Search, Compute, and Stop
Most agent systems fail in predictable ways: they trust model recall too much, use tools without policy, and keep reasoning long after the evidence ran out. CoreLink AI was built to make those failure modes explicit, bounded, and auditable.
Production failures in computer vision are rarely simple 'wrong predictions.' They are complex conceptual drifts—blur, lighting, camera shifts. Here’s how I built a 'flight recorder' to catch them before they become incidents.
December isn’t “dead.” It’s noisy, uneven, and full of timing signals. Here’s what I observed by tracking company hiring momentum daily—and how to prepare for January after the holidays.

The Hiring Momentum Dashboard I Wish Existed
I stopped tracking individual job listings and started tracking hiring behavior—momentum, freezes, job lifespan, and timing. Here’s what changed and why it’s actually useful.
