Six self-taught routes — each one a map of what to learn, in what order, from which free university courses and labs, and how to prove it. No enrolment, no gatekeeping; just the sequence and the sources.
Math → libraries → exact APIs
Six fields — Machine Learning, Deep Learning, LLMs, Reinforcement Learning, Agentic AI, and ML Systems & Hardware — every topic traced from the mathematics that defines it to the library call, with Kaggle and Hugging Face practice.
The India Route
Building autism-therapeutics capability from Bengaluru instead of buying it abroad — open courses, Indian government grants, national-lab tie-ups and contract research, sequenced as an operating plan.
An open-course route
The field is unusually friendly to self-teaching: the best labs are free and hiring leans on demonstrated skill. Foundations, security core, hands-on labs, university depth, a track to specialise in, and how to prove it.
The self-assembled MBA
The first-year core of an MBA, assembled from MIT Sloan, Wharton, Stern, Yale and the IIMs' open courses — four sequenced terms, the case method without the classroom, and turning it into something you can show.
Zero to shipped apps
Harvard, Helsinki, Stanford, MIT, Google and Apple publish complete courses; what self-teaching lacks is sequence and finish lines. Eight milestones — programming and web foundations, full-stack apps, data & APIs, mobile — each ending in something shipped.
From printf to page tables to pixels
C and C++, how the machine works, Unix systems programming, operating systems (build xv6, then your own), the Linux kernel and device drivers, compilers and linkers, and browser engines — from courses that publish their labs and the open codebases themselves.
University OpenCourseWare, public labs, papers and official docs. Anything paid is optional and named as such.
Each route says what comes before what, and why — the dependency graph, not a reading list.
Every module ends in something you can show: a portfolio, a credential, a funded plan, a shipped artefact.
Routes are revised as courses, tools and the job market move. Each page carries its own structure; this page is the index.
