From your first lesson to your first ML offer

Prof builds the bridge.

What we're actually teaching

Assembling a burger at McDonald's doesn't make you a chef. Calling a model doesn't make you an AI engineer.

The Big Mac assembler knows the recipe: lettuce, patty, sauce, bun. Identical every time. The moment the order changes — diabetic, halal, gluten-free — the recipe breaks.

Sound familiar? Calling a model and shipping whatever it returns is not AI engineering.

A real chef can walk into any kitchen. Take butter chicken: it's tomato to onion at 3:1, cashew for body, yogurt-marinated chicken thigh in a clay oven for the char.

That's why the same chef can drop the sugar for a diabetic uncle, swap chicken for paneer for a vegetarian grandma, and dial up the butter for kids who want it “like the restaurant.”

Nothing breaks — because the chef understands the substrate. That's what Prof teaches.

Why fundamentals, why now

Generation is cheap. Judgment is what you are paid for.

The model can do this

You still have to do this

Write the code

Decide what to build — and own it in production

Produce an architecture diagram

Design the distributed system: reliability, latency budgets, and the team who maintains it for years

Optimize a function

Predict the blast radius — how the change propagates across the stack

Answer "how"

Answer "whether" — and own the call when it’s wrong at 3am

The “just-ask-the-LLM” person is not wrong that the model can generate the code. They are wrong that generating the code was ever the hard part.

Drag the variables. Feel why the formula is the formula.

See the mechanism move. Don't just read the formula.

Drag the learning rate. Watch the descent. When it diverges, you'll feel why — not because we told you, because you broke it.

Smooth descent. Each step decreases the loss. This is what η ≪ 2/L feels like.
The lineage

Built the way Karpathy, Sutskever, Hassabis, Dean taught themselves.

No one PhD'd them into greatness. They built from scratch, read the foundational papers, mastered the substrate. Prof's curriculum is the same path.

01
AK

Code is the source of truth.

Andrej Karpathy

Karpathy built micrograd — a working autograd engine — in pure Python before reaching for PyTorch. His "Zero to Hero" course is a manifesto: 10,000 hours of deliberate practice, building from scratch, until the math becomes intuition.

Prof's CNN, RNN, and Transformer courses follow the same arc.

02
IS

Read the 40 papers that contain 90%.

Ilya Sutskever

Sutskever told John Carmack: read these 30–40 papers and you'll know 90% of what matters. The list isn't a fad — it's the foundation. Transformers, attention, scaling laws, representation learning.

Prof's Interview-Readiness sections are organized exactly around these primary sources.

03
DH

Solve intelligence, then use it.

Demis Hassabis

Hassabis coined "jagged intelligence" to explain why an AI tool can win a math olympiad and fail at high-school algebra. The defense is fundamentals — the ability to pressure-test what your tool just told you.

Prof's quizzes, interview-readiness sets, and code labs all train this judgment.

04
JD

The "very bottom" still matters.

Jeff Dean

Dean designed MapReduce, TensorFlow, and the TPU. He's the proof that staff-level engineers master multiple layers of the stack — not just the framework du jour. Google's interview process, despite the AI tools, is still focused on data structures and algorithms.

Prof's curriculum mirrors that staircase.

The curriculum

Fundamentals first. Tools second.

One track. From regression to a multi-agent system — and the interview that turns the work into an offer.

The platform

We are not a passive video platform.

An AI tutor that triggers Analytical Thinking

The tutor doesn't tell you the answer. It nudges, asks back, and forces the cognitive effort that turns information into retention.

Gamified visual animations from first principles

Interactive visualizations of gradient descent, attention heads, Neural Network Training, causal masking. You see the mechanism move — not just a static slide.

Recent interview questions from BigTech and elite startups

Per-course Interview-Readiness sets, refreshed quarterly, drawn from actual loops at Google, Meta, OpenAI, Microsoft, Anthropic, Databricks, and others.

Quizzes on every lesson

Formative assessment so you know whether you understood it — not just whether you watched it.

Three formats, your choice

Video for the watchers. Text for the fast readers. Code labs for the builders. Same lesson, three ways through.

Built around fundamentals, not frameworks

When PyTorch becomes Jax becomes the next thing, your investment doesn't depreciate. The fundamentals do.

They came for the courses. They stayed for the rigor.

Assistant Professor at IILM University

2012 · The big bang

In 2012, Alex Krizhevsky trained a CNN on two $500 NVIDIA gaming GPUs split across his desk. He won ImageNet by a margin nobody expected, and the world realized that NVIDIA's six-year, Wall-Street-hated bet on CUDA was actually the secret to modern AI. The lesson: fundamentals about what hardware can do, married to the courage to ignore consensus, makes empires. That's the engineer Prof builds.

Issued under the seal of Professor

Four lines from the Memorandum.

Generation is cheap. Judgment is what you are paid for.

Chapter I

Tools have a half-life of eighteen months. Fundamentals, of decades.

Chapter III

The argument is not against the tools. The tools are extraordinary. The argument is against the idea that using the tools is the same as understanding the systems.

Chapter VII

Professor stands for rigor in a market flooded with fluff.

Chapter VI

Read the full memorandum

Vol. I, No. 01 · Privately circulated

Where Prof graduates land

Five tracks. Seventeen employers. One curriculum.

The 2026 AI hiring market is bifurcated: an oversupply of API-callers at the L4 floor, and a genuine scarcity of judgment-capable engineers at the L6 Staff bar. The bridge between $400K and $775K total comp is built almost entirely from the fundamentals AI tools cannot generate. Prof exists to put you on the scarcity side of that gap.

L4
Mid-Level

Independent on complex tasks; owns a medium project

$250K – $350K
L5
Senior

Leads major projects; tech lead for a team

$400K – $550K
L6
Staff

Cross-team influence; ambiguous problems; domain expert

$580K – $775K
L7
Senior Staff / Principal

Division-wide strategy; multi-year roadmaps

$650K – $1.1M+

“The L5 → L6 jump from Senior to Staff is +$200K of total compensation. The skills that close it cannot be generated by AI — that's exactly why we teach them.”
