A free self-paced curriculum for the Forward Deployed Engineer role — the person who sits with a customer and turns an AI model into a system that actually runs in production. 11 modules, 150+ topic articles, 700+ open-book questions and 15 daily drill questions, covering systems thinking, problem decomposition, LLM/RAG/agent architecture, data and event systems, physical AI and robotics, plus client discovery, integration, deployment and stakeholder management. It also publishes a map of 15 layers of the modern AI engineering stack drawn from real FDE and AI-engineer job specs, with links out to where to learn each one.
Why I recommend it: The whole curriculum opens without an account or a card — I checked — and an account only saves your progress. There is no pricing page anywhere on it, so nothing is being held back behind a paywall today. Worth knowing why this matters: 'Forward Deployed Engineer' is a job title that is actually being hired for right now, and it pays like engineering while rewarding the consulting side most engineers avoid. Two flags. It is one person's independent site, not an accredited course or a certificate anyone will recognize — the value is the material, not a credential. And it makes a strong claim, that foundation models are becoming a commodity and the money lives in the last mile; that is an argument, not a measured finding, so read it as a well-argued position.
A free agent skill that turns a codebase or a plain-English system description into an interactive architecture, workflow, sequence or data-flow diagram you can share as a single file.
Why I recommend it: Handy for explaining how something works in an interview or a proposal without hand-drawing diagrams.
Newsletter breaking down system design and backend engineering concepts with clear diagrams — interview-grade explanations of how large systems work.
Why I recommend it: Use the diagrams as interview prep. If you can redraw one from memory and explain the tradeoffs out loud, you are ready to talk about it in a system design round.
Interview prep and career advice for developers from Fahim ul Haq, drawing on 15+ years in big tech.
In plain terms: A newsletter of coding interview prep and tech career advice from a longtime engineer and founder. Focused on interview patterns, system design, and growth in engineering roles.
From the site: Interview prep and career advice for devs. Tips and takeaways from 15+ years in tech.
Why I recommend it: Pair this with mock practice. The system design and interview breakdowns map closely to what big tech actually asks.
Slide deck of advice from working technology architects and engineers: how to open strong, when to ask clarifying questions, what depth is expected at junior vs. senior level, and how to talk through architecture, scaling, and performance.
In plain terms: This slide deck shares advice from working tech professionals on handling technical interviews. Use it to learn how to explain your coding process, tackle tough questions, and tailor your answers for junior or senior roles.
Why I recommend it: Lead with your strongest projects — interviewers dig into whatever you highlight.
