すべてのコースは最終的に 成果物 レビュアーが信頼するもの。

Build maps you can defend the edges of — for systems, codebases, and outages.

Control flow, state, and debugging as a diagnosis discipline — with a debug log artifact.

APIs, queues, idempotency, and failure repair under real load. Ends in a production API.

Product surfaces with real data flow, accessibility, and request-path judgment.

Schemas that survive review — modeling, constraints, and migration judgment.

turn messy real-world engineering problems into concept maps, decisions, proof artifacts, repairs, and transferable senior-level explanations

Lists, maps, and real data

Version control & the shell

move through a codebase from the terminal and leave evidence; write small, tested Python functions and workflows; model simple records with types and dataclasses; use lists, dictionaries, sets, JSO…

Calling models like a pro

Reliable prompting & evals

Grounded, cited answers

Tool-using AI agents

complete AI Engineering, RAG, Evals, Safety, And LLMOps with inspectable artifacts, realistic failure repair, proof evidence, explain-back, transfer, and portfolio packaging

From first principles to staff-level architecture — with real design labs, not just diagrams.

diagnose and design network paths across DNS, HTTP, TLS, routing, load balancing, cloud networks, Kubernetes networking, and security controls

turn product problems into user journeys, accessible screens, design-system decisions, implemented flows, usability evidence, and metric hypotheses

design golden paths, service templates, CI/CD, IaC, environment workflows, secrets, observability, policy, and platform adoption evidence

Ship a full-stack app

Payments & accounts

complete Observability Reliability And Performance with inspectable artifacts, realistic failure repair, proof evidence, explain-back, transfer, and portfolio packaging

lead ambiguous engineering work through strategy, architecture influence, review, execution planning, incident leadership, mentoring, and stakeholder communication

complete Interview Career And Portfolio with inspectable artifacts, realistic failure repair, proof evidence, explain-back, transfer, and portfolio packaging

complete Product Execution And Market Feedback with inspectable artifacts, realistic failure repair, proof evidence, explain-back, transfer, and portfolio packaging

The mechanics beneath every language: memory, state, complexity, and honest debugging.

Just enough Python to run every lab in the academy.

Tradeoffs, capacity, and written decisions that survive review. Ends in a design packet.

Threat modeling, auth, and blast-radius thinking grounded in OWASP.

Native constraints, offline state, and release judgment for mobile surfaces.

Tests as proof design: what to check, what to skip, and how to defend both.

Packets to policies — diagnose the layer, not the symptom.

Design judgment for people who ship: hierarchy, states, and honest interfaces.

Pipelines, contracts, and the difference between data that moves and data you can trust.

Retrieval, eval gates, failure repair, and shipping AI systems you can defend.

Deploys, rollbacks, and runbooks — operations as engineering, not ritual.

See the system before it fails: SLOs, traces, and performance judgment.

Golden paths and paved roads — build the platform your team actually uses.

The systems around the software: identity, procurement, and integration judgment.

Turn your evidence ledger into offers — interviews as proof presentations.

Ship, measure, decide: product judgment for engineers who own outcomes.

Leverage, writing, and decisions at the level where code stops being the job.
