Phase 0: The FDE Role & Deployment Mindset · 40 min · Python · SQL · Docker

The T-Shaped FDE Profile

Deep enough to build it, broad enough to ship it.

Hiring signal: FDE interviews test breadth across the T-profile: a candidate who can code a RAG pipeline (vertical) but also explain SAML SSO and VPC configuration (horizontal) demonstrates the T-shape. Specialists who lack breadth fail the system design round; generalists who lack depth fail the coding round.

What you will learn

Map the FDE T-profile: deep in Python, SQL, data engineering, RAG, agents; broad across SSO, cloud, Docker, dbt, enterprise platforms
Assess your current skills against the T-profile and identify gaps
Understand why product sense is a required FDE skill, not optional
Identify the consulting layer skills: Minto Pyramid, decomposition, stakeholder management

What You'll Learn

By the end of this lesson, you'll be able to:

Map the FDE T-profile: deep in Python, SQL, data engineering, RAG, agents; broad across SSO, cloud, Docker, dbt, enterprise platforms
Assess your current skills against the T-profile and identify gaps
Understand why product sense is a required FDE skill, not optional
Identify the consulting layer skills: Minto Pyramid, decomposition, stakeholder management

The Problem

The FDE role demands a skill profile that doesn't fit any single engineering discipline. You need deep expertise in one area (the vertical of the T) — typically ML/AI engineering — plus broad working knowledge across data engineering, cloud infrastructure, security, enterprise integration, and client communication (the horizontal bar). Too narrow and you can't handle the full deployment scope; too broad and you can't go deep enough on the AI components.
