Performance, SLOs & Data-store Signals
One availability SLO on “the api service” can be green while users wait forever for async fulfillment. MNCs define SLIs per *user journey* and write error-budget policies before the incident. Audience: Final-year students and early-career engineers (0–3 years). Prerequisites: obs-06-profiling-and-ebpf System under observation: api (Express) → SNS → SQS → worker → S3 (+ Postgres/Redis from phase 07)…

Foundations: Modern SDLC + the AI-Augmented Engineer
Foundations: Modern SDLC + the AI-Augmented Engineer
Built for final-year students and early-career engineers. A grounding module: we define the modern SDLC (Plan → Design → Develop → Test → Release → Operate → Learn), show where AI augmentation slots in, and reset expectations about what an engineer's day looks like when an AI assistant is part of the workflow. By the end, every learner has a one-page diagram of an SDLC for a real product and a written list of…

AI-Assisted Development & Vibe Coding
AI-Assisted Development & Vibe Coding
The signature module of the program. Learners spend most of the session doing, not listening. We tour the major AI coding tools (Cursor, GitHub Copilot, Claude Code, Aider), introduce four prompt patterns, then run a debug lab where each learner fixes a broken FastAPI endpoint using AI as a pair-programmer and documents every prompt. The point is to make AI a habit, not a curiosity.

Prompt Engineering for Developers
Prompt Engineering for Developers
Module 02 introduced four patterns. This module goes one layer deeper: few-shot, chaining, output evaluation, and the discipline of a prompt library. The lab is hands-on: each learner builds a small reusable library for one task they actually do.

Software Design: SOLID, clean architecture, DDD basics
Most early-career engineers can recite SOLID but can't spot violations in their own code. This module teaches recognition — then practice — in two languages. We finish with a refactor lab where AI is the pair and the rule is "tests stay green".
