I build things where machine learning and people systems meet. It wasn't a clean plan. It just kept happening. I started in offensive security, reverse engineering binaries, writing exploit chains, finding zero-days across 
Now I train and deploy custom models (domain-specific transformers, graph neural networks, contrastive embedding systems) for the problems where off-the-shelf models quietly fail. I also do niche headhunting, placing senior engineering and ML leaders at Fortune 500 companies. Sounds like two different jobs. It isn't. Same instinct in both, honestly: figuring out what holds under real-world pressure, and what collapses the moment conditions shift.
Most AI fails quietly: fluent answers, brittle execution. So I run 
Trumbo, an AI lab building agentic coding tools, agentic cybersecurity, and Quartz, the model underneath them all. Quartz is a sparse MoE pretrained on code, security, and synthetic agent trajectories; Lite handles reflex, Hyper runs plan→reason→verify loops, and Sentinel runs 200+ deterministic checks before anything ships. The model does the work first. The explanation comes after it's been checked. Learn more about Trumbo →
And then there's 
Glide, the people-systems product. Under the hood it's heavier than it looks: a layout-aware extractor turns a résumé into a typed graph, a cross-encoder scores fit over a heterogeneous graph of candidates, jobs, skills, and companies, skill claims get checked against actual work history, and advice is grounded in live data and aligned on what genuinely helps people decide. No keyword roulette: matching happens over a knowledge graph, not a keyword list. Different machinery, same instinct as the lab: find what holds under pressure, and what collapses when conditions shift.

The Mirror Problem
Published: at 03:44 PMA model trained on its own output loses range generation after generation, the tails of its distribution slowly disappearing. I hit this kind of loop in my own systems, and it changed how I think about the difference between a model learning and a mirror reflecting.
The Forgiveness That Dies First
Published: at 01:42 PMmuP makes learning-rate transfer work by keeping the set of good rates wide. I measured what low precision does to that forgiveness, and the surprising part: the transfer survives. The forgiveness is what dies first.
Making AI Agents Think Before They Retrieve
Published: at 09:00 PMEvery memory-augmented agent runs the same pipeline: query, retrieve, answer. Nobody asks whether retrieval should happen at all. Here's the missing cognitive control plane that turns memory access from a reflex into a decision, with controller architectures, a formal definition, benchmarks, and working code.
Why Smart Companies Stop Knowing Things
Published: at 05:58 PMSmart companies rarely fail because nobody has data. They fail because reality gets softened, translated, and delayed until the organization can no longer tell what is true.
Why Neural Networks Solve the Wrong Equation
Published: at 03:45 AMPhysics-Informed Neural Networks promise to solve the equations governing reality: heat flow, fluid dynamics, structural stress. But nearly everyone enforces boundary conditions wrong, producing low training losses and physically meaningless results. Here's the fix nobody uses.
Why I Am Building Glide
Published: at 04:33 AM242 applications per opening. 0.4% success rate. Most candidates ghosted. I spent years inside recruiting watching brilliant people get crushed by a system nobody designed. So I built custom ML models, graph neural networks, and a career intelligence platform from scratch to fix it.
Where Decisions Disappear
Published: at 12:02 AMEnterprise software records outcomes. The next shift will come from systems that preserve reasoning, so organizations can remember how they decided, not just what they did.
Consciousness Is a Conversation
Published: at 03:15 AMWhat if consciousness isn't a thing you have, but a language you speak? A look at why selfhood might emerge not from computation, but from the lossy, imperfect exchange of messages between minds trying to understand each other.
Why Perfect Intelligence Must Go Blind
Published: at 09:15 AMWhy true intelligence isn’t total awareness, but the ability to leave out the right things, and how selective blindness turns overwhelming detail into decisive action.
The Momentum Trap
Published: at 01:12 PMWhy the real challenge of productivity isn't focus or discipline. It's understanding momentum. And how that understanding changes everything about how we work.
Inverse Scaling Laws in Neural Networks
Published: at 09:19 AMA comprehensive examination of inverse scaling in large language models, where increased computational power paradoxically leads to degraded performance on specific tasks, challenging our fundamental assumptions about AI progress.

Finding True Intelligence in Language Models
Published: at 04:54 AMWhy autoregressive language models might be more parlor trick than true intelligence, and how the search for meaningful latent representations could transform how AI understands language.
