Goal: Land a Forward Deployed Engineer (FDE) role at an AI startup / lab.

How to use: Work skill-by-skill. Each skill lists topics and resources. Priority tags tell you where your gaps actually are — spend time there, skim the 🟢 strengths.

Priority legend (based on your profile)

Tag Meaning Why
🔴 Focus Real gap — most of your time here Solo low-code/AI work doesn't build this
🟡 Level-up Partial — sharpen it You touch it but not to FDE bar
🟢 Strength Polish only 6yr client delivery + CPO already cover this

Your edge: end-to-end solo delivery, real enterprise clients (Miro, JTI, SDG, Next Energy, Rebel Fund), AI-native stack (n8n multi-agent, Supabase, MCP, LLM agents), CPO-level product+GTM sense, days-not-weeks prototyping.

The delta to close: traditional SWE rigor · agent/eval rigor over vibe-checks · enterprise system design (SSO/VPC/compliance) · the case/decomposition interview.


1. 🔴 Software Engineering Rigor (Python-first)

FDE coding rounds are integration/debugging/production-quality code — not LeetCode. But you need to write idiomatic Python in a real codebase, fast and clean.

Topic Priority Resources
Idiomatic Python (stdlib, typing, dataclasses, async) 🔴 AI Eng from Scratch — Python track, [Fluent Python (book)]
Data structures & algorithms (light — enough to reason, not grind) 🟡 NeetCode 150 (skim patterns)
Git, testing (pytest), CI, code review culture 🔴 pytest docs, GitHub Actions basics
Reading & debugging unfamiliar/large codebases 🔴 Practice on SWE-bench Verified tasks
API integration + data transformation/pipelines 🟡 Build against real 3rd-party APIs (you already do this)

2. 🔴 LLM & Agent Engineering

The core of an AI FDE. You build agents already — the gap is rigor: evals, reliability, structured tool-use, cost/latency discipline.

Topic Priority Resources
LLM API mastery: tool-calling, structured output, streaming 🟡 Anthropic docs — tool use, OpenAI cookbook
Prompt engineering & context design 🟢 Anthropic prompting guide
Agent loops, planning, memory, tool orchestration 🟡 AI Eng from Scratch — agent phases
MCP server/client design 🟢 You already do this — document it as a portfolio piece
Evals & observability (the real gap) 🔴 Anthropic evals guide, build an eval harness for your agent
Reliability: retries, guardrails, failure handling, pass^k 🔴 τ-bench paper/method
Cost / latency / token tradeoffs 🟡 Instrument your own runs

3. 🟡 RAG & Retrieval

A sub-skill of agents, but big enough to isolate. Directly tested in AI-FDE system design.

Topic Priority Resources
Embeddings, chunking, vector DBs (pgvector/Supabase) 🟡 Supabase pgvector
Retrieval quality, hybrid search, reranking 🔴 Enterprise RAG Challenge (warm-up capstone)
Query routing, expansion, self-consistency 🟡 ERC winning write-ups (Ilya Rice)
Citations, grounding, hallucination control 🔴 Build "chat with docs" + citations
