I am interested in intelligence as both a technical and existential problem. That draws me toward , cognition, consciousness, philosophy, and metaphysics, but also toward building AI and ML systems that live at the intersection of frontier research, applied research, and real engineering. I believe more in learning than in static knowing, in extreme experimentation over posture, and in interdisciplinary interaction as a way of discovering better questions and better systems.
I read constantly to understand the world, human beings, AI, and myself. I bring 6.5+ years of experience across the stack of analytics and data science, with a career arc that has gone from sensors to tensors and has been shaped strongly by and complexity thinking. I am currently an MS Data Science student at Columbia, working toward top AI labs and, in the longer run, toward building a decision-engineering company of my own. pracha.me is where that learning, experimentation, and synthesis become visible.
- Frontier systems: reasoning, agents, interpretability, evaluation, causality, and world models.
- Applied intelligence: practical AI/ML systems, forecasting, decision systems, experimentation, and enterprise problem solving.
- Foundations: probability, optimization, control, information, dynamics, and scientific views of intelligence.
- Outputs: primers, builds, notes, readings, synthesis pieces, musings, and open-source implementations.
Work Across The Stack
The site is organized around five reinforcing modes of work: frontier systems, decision engineering, builds, foundations, and library work. Each one is meant to strengthen the others rather than live in isolation.
Frontier AI and Research Engineering
Reasoning systems, agents, model behavior, interpretability, world models, causality, evaluation, and the engineering discipline around advanced AI.
Enterprise AI and Forward-Deployed Problem Solving
End-to-end AI systems for real workflows: operational decision loops, enterprise tooling, industry systems, and forward-deployed engineering at the intersection of AI, ML, data, and software.
Systems Work, Prototypes, and Research Engineering
Longer-horizon technical builds, faster prototypes, and an engineering-practice layer across evals, agents, data systems, inference, and research engineering.
Math, Theory, and Deep Notes
Foundational notes across statistics, optimization, control, scientific ML, and the broader conceptual machinery needed to understand intelligence well.
Readings, Notes, and Long-Form Synthesis
Source material, working notes, primers, and longer-form synthesis pieces that turn technical deep dives into reusable frameworks and judgment.
Flagship Work
These are the best current entry points into the site: one frontier primer, two systems builds, and one foundations-oriented reference artifact.
The Philosophical Roots of Frontier AI
A multi-part primer connecting philosophy, ML schools, lab strategies, reasoning systems, and the current frontier of AI research and engineering.
Zero-Shot Coordination in Multi-Agent RL
Convention emergence via IPPO. When does ad-hoc teamwork fail — and what enables it without prior agreement?
Causal State-Space Models
SCM-augmented Mamba for counterfactual forecasting. Granger causality vs. do-calculus interventions.
AI / ML Course Atlas Across Leading Universities
A structured reference to public AI, ML, DL, theory, systems, and frontier research courses across leading universities.
Reading Paths
The site is meant to work for different readers. These paths help you enter from the angle that matches your current stage and interests.
Foundations, maps, and learning paths
Start with course maps, frontier primers, and conceptual notes if you want structure before depth.
Operational AI and decision systems
Start here if you care about turning AI capability into real workflows, enterprise systems, and forward-deployed problem solving.
Library: readings, notes, and synthesis
Use the library layer to see how readings and notes mature into longer-form technical artifacts and synthesis.
Frontier maps and strategic judgment
Start with the frontier primer if you want a higher-level map of the research landscape, lab bets, and the philosophical structure underneath them.
