Engineering courses
built for builders.

Structured, deep-dive curricula - starting with AI, infrastructure, and security, with more domains on the way — for engineers who want to understand and operate production systems, not just use them.

Available Courses

7-Day Production Engineering

LLM Systems Engineering

GPU architecture, inference engines, distributed training, RAG pipelines, and production observability — everything you need to build and operate LLMs at scale.

Backend Engineering for the AI Era

Build, scale, and operate production backends that serve both human and AI traffic — APIs and streaming, storage from Postgres to vector stores, caching, queues, distributed systems, reliability, observability, and the patterns that emerged when LLMs became the slowest dependency in your stack.

7-Day Practical Shipping Course

From Code to Internet: Deployment & Operations

Everything that happens after the code compiles. DNS, Linux servers, NGINX, TLS, systemd, zero-downtime deploys, Docker, CI/CD, monitoring, and on-call — the boring, load-bearing skills that separate a localhost demo from a public URL someone is willing to pay for.

7-Day Production Agent Engineering

Agentic AI with LLM APIs

Tool use, agent loops, memory, multi-agent orchestration, computer use, and production observability — build LLM agents that ship, not demos.

7-Day Defensive Security

Application Security Engineering

Threat modeling, the CIA triad, OWASP Top 10, modern crypto, authn/authz, network and cloud hardening, and incident response — the security mental models every engineer should own.
