Free 30-Day Challenge

30 AI systems.
30 days.
30 live links.

Build30 is a free challenge where you build one real AI engineering artifact every day for 30 days. No certificates. No theory lectures. Just 30 deployed projects and the confidence that only comes from shipping.

Days of building

4 hrs

Per day, average

3

Tiers — Foundational, Builder, Architect

Free forever. No credit card. No catch. Built by Himanshu Ramchandani — AI engineer with 50,000+ followers in the AI builder community.

You do not need another certificate. You need 30 live links.

Every platform gives you something to learn. None of them give you something to show.

Build30 is different. By Day 30, you have 30 deployed AI projects. Real code. Real links. Real proof that you can build.

Recruiters look at what you shipped. Clients look at what you shipped. You look at what you shipped. Everything else is noise.

The goal is not to learn AI. The goal is to build AI. The learning is the side effect.

The structure

One idea. One artifact. One day.

Every day you get an idea brief. You have a suggested learning resource (30 minutes maximum). Then you build for 3–4 hours. You deploy it. You document it in one post. That is the whole thing. No long lectures to sit through. No assignments to submit. No grades.

The daily 4-hour shape

1
20 minRead the idea brief
2
40 minStudy the one concept you need for today
3
2 hr 30 minBuild the artifact
4
20 minDeploy it (Hugging Face Spaces, Vercel, Railway, or GitHub)
5
10 minWrite one post about what you built

Total: 4 hours. One artifact. Deployed. Documented. Done. The 4 hours is a guideline, not a rule. Some days take 2 hours. Some take 6. That is building.

The 30-day progression

You will not start with RAG. You will earn it.

Build30 runs in three tiers. Each tier builds on the last. By Day 30, you have touched every major area of AI engineering.

Days 1–10

Understand how the engine works.

The first 10 days are the hardest and the most important. No wrappers. No abstractions. You build the core components of AI systems from scratch — the same ones hidden under libraries you use every day.

By Day 10, you know how attention works because you built it. You know how tokenization works because you implemented BPE yourself. You know what autograd does because you wrote one.

Day 1: Autograd engine from scratch (no PyTorch)
Day 2: BPE tokenizer
Day 3: Multi-head attention mechanism
Day 5: Transformer block
Day 7: Vector database with HNSW indexing
Day 10: RAG pipeline with basic retrieval
Days 11–22

Build systems that could serve real users.

From Day 11, deployment is mandatory. Every artifact must be live. You move from understanding components to building systems — serving layers, fine-tuning pipelines, agents, multimodal tools.

This is where production thinking starts. You are not just making things work. You are making things work under pressure.

Day 11: LLM serving layer with dynamic batching
Day 13: LoRA fine-tuning pipeline
Day 16: Stateful AI agent with reflective memory
Day 19: Multimodal embedding pipeline
Day 22: CI/CD pipeline for an AI service
Days 23–30

Ship things that matter.

The last 8 days are synthesis. You stop building components and start building systems. You think at the level of trade-offs, failure modes, and real-world constraints.

Day 30 is not a rest day. Day 30 is portfolio day. You deploy your Build30 portfolio page — a public record of every artifact from the previous 29 days.

Day 23: MLOps monitoring and observability dashboard
Day 25: LLM safety and alignment evaluation framework
Day 28: Autonomous research agent
Day 29: Capstone product with real users and Stripe
Day 30: Your public Build30 portfolio
The full schedule

30 ideas. No filler.

Every idea is scoped for a 4-hour build session. Every artifact is deployable. Every day builds on what came before.

The outcome

By Day 30 you have proof.

30 live deployed projects

Not GitHub repos with no commits. Not Colab notebooks. Deployed. Shareable. Live URLs.

A public portfolio page

buildership.io/builders/[yourname] — a permanent record of everything you shipped. Show it in interviews. Share it on LinkedIn. Link it in your bio.

30 days of documented builds

30 LinkedIn posts or Twitter threads showing your build log. A public record of 30 days of serious engineering work.

A working understanding of the full AI stack

Not a surface-level survey. You built the components. You hit the real errors. You understand why things work, not just how to use them.

Eligibility for AI Engineer HQ Accelerator Cohort 2

Build30 completers get priority access to the next Accelerator cohort. A completed Build30 portfolio is a requirement for application.

The confidence that only comes from shipping

This one does not show up in a job description. But it shows up in every conversation. Recruiters feel it. Founders feel it. You feel it.

Build30 is for intermediate builders.

If you are a complete beginner to Python and ML, start somewhere else first. Build30 is intense and moves fast. Day 1 is autograd from scratch. If you have no ML foundation, Day 1 will overwhelm you.

If you are a developer who knows Python, has done some ML tutorials or courses, and has never shipped anything production-level — this is exactly for you.

If you are an ML engineer who has shipped models but has never built the infrastructure layer — this is for you.

If you are a developer from a non-ML background who wants to break into AI engineering seriously — this is for you.

The one rule: You have to actually build every day. Not catch up on weekends. Not skim the brief and read the solution. Build it. Deploy it. Post it.

Build30 is free. One upgrade option exists.

The connection

Build30 and Buildership work together.

Build30 is the free challenge. Buildership is the platform.

When Build30 ends, every artifact you built corresponds to a full idea in the Buildership library. The library has the full curriculum, deeper build docs, and the traction guide for each one.

Build30 gives you the taste. Buildership gives you the depth.

And if you want to keep building after 30 days — there are 40+ more ideas in the library waiting.
