one estate · three interfaces $79 Blueprint

for data engineers, 2–6 years in

Stop collecting tutorials. Ship one platform.

One data estate. Three interfaces onto it: MCP tools, vector retrieval, and ML features. One governance story that holds across all three.

Most of the material in here exists free somewhere. MIT OpenCourseWare, Stanford CS229, Karpathy's Zero to Hero, DataTalks.Club's Zoomcamps. We name all of them below and say plainly what $79 adds, which is a sequence and one finished artifact, not more content.

what people actually said

You are not behind. You are scattered.

Three posts from our research. Every one of them is a person doing the work and still feeling like the ground moves every quarter.

"Every time I try to learn a new skill related to AI, it becomes obsolete in a month or two... I always feel like I am behind and it's very tiring."

Employed engineer · r/cscareerquestions, thread score 53

"They pointed out my AI/ML project experience doesn't reflect the current industry. They're looking for: LLMs and Transformers, RAG and embeddings, Vector databases, Agents and tool calling, LLM evaluation, Fine-tuning... When I try random YouTube tutorials I either find them too basic or end up jumping between technologies without understanding what I should actually learn."

MSc grad, rejected mid-interview · r/learnmachinelearning, thread score 20

"I can't shake this feeling that maybe I'll never get hired again in this field."

Systems / DevOps engineer · r/cscareerquestions, thread score 38

Scores shown are the thread's score, not the comment's. Sources: 01-research/SOURCES.txt.

before you spend anything

Most of this is free. Here is where.

When someone on r/learnmachinelearning asks which course to buy, the highest-voted answer is usually a list of free resources. That answer is correct. These four cover most of the underlying material, they are good, and they cost nothing:

  • MIT OpenCourseWareFull university courses, free, no signup.
  • Stanford CS229The machine-learning foundations, lectures and notes online.
  • Karpathy's Zero to HeroBuilds the model layer from scratch, on video, free.
  • DataTalks.Club ZoomcampsLLM Zoomcamp and AI Dev Tools Zoomcamp. Free, cohort-run, and the AI Dev Tools one covers MCP by name.

If you will finish that path on your own, finish it. You do not need this.

What $79 adds

Not more content. A sequence and one artifact.

  • One order to do things in, from assessing a real data estate to shipping the thing, with a day-by-day plan.
  • The three interfaces treated as one system instead of three separate courses that never meet.
  • A governance and lineage story that spans all three, which is the part the free material handles one silo at a time.
  • A scope cut written for each day you fall behind, so the build survives a bad week.
  • A write-up chapter for presenting the finished platform, including the limits you should state yourself.

MCP, RAG and vector databases are not new and we do not claim they are. Coursera sells a specialization on this stack and Maven runs bootcamps on it. What is on offer here is synthesis and order, at a lower price, in a format you can read in an afternoon.

"A working RAG pipeline with a clean UI will beat 50 IBM certificates every single time." A hiring-side commenter on r/cscareerquestions, thread score 6. He is right, which is why this is not a certificate. There is nothing here to put in the certifications section of a résumé. The output is the platform you build.

how the build runs

Assess, design, ship in fourteen days.

STEP 01

Score the estate you already have

Run the readiness checklist against your own employer's data: sources, ownership, freshness, PII, access paths. It produces a one-page score, and it tells you what to leave out.

Chapters 00–02
STEP 02

Design three interfaces onto one estate

The reference architecture, then each interface in turn: MCP tools with scoping and read-only boundaries, retrieval with chunking against real schemas, features with point-in-time correctness. Cheap and expensive variant for every decision.

Chapters 03–07
STEP 03

Build it in fourteen days, then write it up

A day-by-day plan with a scope cut for each day you slip. It ends with a one-page write-up, a diagram, the three questions you will be asked about it, and the honest limits to state before anyone finds them.

Chapters 08–09

what is in the zip

  1. Start here: what this is, what it is not, the free alternatives named outright
  2. One estate, three interfaces: the core argument, and why protocol-shaped skills expire
  3. Score your estate: the readiness checklist, producing a one-page score
  4. The target design: the reference architecture, with cheap and expensive variants
  5. Interface 1, tools (MCP): granularity, scoping, auth, what not to expose
  6. Interface 2, vectors: chunking against real schemas, freshness, hybrid search, evaluation
  7. Interface 3, features: point-in-time correctness, training and serving skew
  8. One governance story: access, PII, lineage and audit across all three at once
  9. The 14-day build: day by day, with a scope cut for each day you fall behind
  10. Show it to a hiring manager: the write-up, the diagram, the three questions, the limits

Ten chapters. There is no public reference repo yet, so it is not part of what you are buying. If one ships later, Blueprint buyers get the link at no extra cost.

30-day refund, no questions asked. Email support@mizudev.com and the money goes back. You keep the files, because chasing a download is not worth anyone's afternoon.

This is study material and a build plan. It is not a certificate, not a qualification, and it makes no claim about what any employer will do.

the awkward questions

Ask them first.

Why pay $79 when this is free elsewhere?

Because the free material is not in an order, and the ordering is the hard part. MIT OCW, CS229, Karpathy's Zero to Hero and the DataTalks.Club Zoomcamps are all free and all good, and the Zoomcamps cover MCP already. What you are paying for is one sequence that ends in one working platform, with the three interfaces treated as one system and one governance story across them. If you already have a plan you will finish, use the free path and keep the $79.

Is this a certificate?

No, and it is not described as one anywhere. Two hiring-side commenters in our own research said certificates do not move their decisions, and one of them put it as "a working RAG pipeline with a clean UI will beat 50 IBM certificates every single time". We agree with him. There is no exam, no badge, and nothing to add to a certifications list. What you end up with is a platform you built and a write-up of how it works.

Is MCP just hype?

It might be. Protocols get replaced. MCP is one chapter of ten here, and the argument of the book is the opposite of a protocol bet: an estate outlives the interfaces bolted onto it, so learn the estate and treat the protocol as swappable. MCP is also not new or uncontested. Coursera sells a specialization covering this stack and Maven runs paid bootcamps on it, which is exactly why the claim here is synthesis rather than novelty.

What if I don't have company data to practise on?

The assessment chapter is written to run against a real estate, ideally your employer's, because the interesting problems are ownership, freshness, PII and access paths, and those only show up in data somebody depends on. If work data is off limits, run the same checklist against any dataset that has real owners and goes stale, such as an open government or transit feed with a live update schedule. The build plan works either way, and chapter 03 gives a cheap variant of every architecture decision so the whole thing runs on a laptop.

Being straight about it: this is the part of the material that is weaker without an employer estate behind it.

What exactly do I get for $79?

One zip, downloaded straight after payment. In it: the 10 chapters as a single PDF, the same 10 chapters as editable .docx files, and the markdown sources. The chapter list is above this section, in full. There is no video, no cohort, no Slack, and no reference repo yet.

What are your refund terms?

30 days, no questions asked. Email support@mizudev.com from the address you paid with and say refund. A person reads it.
