> A focused 90-day route to one deployed backend project, using AI tools for repetition and feedback without treating them as a substitute for fundamentals.

## Why 90 days

Ninety days is not a promise to replace a full academy or bootcamp, master the fundamentals, or secure a job. It is a deliberately narrow sprint: one language, one framework, and **one deployed project you can explain without the AI beside you**. Use copilots for repetitive work and fast feedback, but prioritize review, tests, and a written record of failures. Continue filling foundational gaps after the sprint.

## The 90 days, in 4 phases

| Phase | Window | Deliverable |
|---|---|---|
| Phase 1 — Environment | Week 1~2 | Local + cloud + Git wired, AI copilot loop habituated |
| Phase 2 — Language & Framework | Week 3~6 | One language + one framework feel native to your fingers |
| Phase 3 — Real project | Week 7~11 | One service an outside user can run |
| Phase 4 — Resume & apply | Week 12~13 | Resume, portfolio, and an application-response log |

## Phase 1 — Environment

- VS Code + Cursor + GitHub Copilot or Claude Code
- WSL2 (Windows) or macOS as a baseline
- A 3-minute mental model of HTTP, DNS, and TLS — depth comes later
- The AI pair-programming loop: **you choose the structure, AI scaffolds, you review.**

If you stall in week 1, the 90 days collapse. Force yourself to complete one full cycle — `git clone → run locally → push → deploy` — before the first week ends.

## Phase 2 — Language & Framework

Three tracks. Pick one, then 4 weeks of total commitment.

| Track | Best fit | Core stack |
|---|---|---|
| **Node.js** | Broad server ecosystem; verify against target listings | TypeScript + NestJS or Hono |
| **Python** | AI/data adjacency | FastAPI + Pydantic |
| **Go** | Infra & high-perf | Gin + sqlc |

**Decision-paralysis rule**: 2 hours of debate; if undecided, choose Node.js. Move.

Weekly artifacts:
- Week 3: single-route API with one DB table CRUD
- Week 4: auth + middleware + error handling
- Week 5: external API + queue (OpenWeather, Telegram, etc.)
- Week 6: tests + Docker + GitHub Actions CI

## Phase 3 — Real project

This is the inflection. Build for **one defined user and one recurring workflow**, then recruit a small number of testers. Avoid arbitrary user or revenue targets and do not treat a to-do clone as proof by itself.

Reasonable categories:
- A career×AI tool (a niche workflow automated for one profession)
- A small SaaS that processes payments end-to-end
- An open-source library shipped on npm or PyPI

Project checklist:
- Auth (email + OAuth)
- DB schema + migrations
- API surface (REST or tRPC)
- Payments (Stripe or Toss)
- Deploy + custom domain + HTTPS
- README + usage docs + 60-second demo

**Decision rule**: add payments only when the chosen problem needs them. Implement test-mode failures and refunds, then document the trade-off. Payments do not guarantee stronger hiring outcomes; observability, security, or tests may be the more useful depth signal.

## Phase 4 — Apply

- Compare resume and job-description language → [/resume](/resume)
- GitHub contribution graph + pinned repos cleaned up
- English LinkedIn profile (apply globally too)
- A sustainable weekly application cap, with job, resume version, and response logged

The week before interviews, record and review your own answers, then use the interview guides in [/match](/match) to check evidence, length, and structure.

## Common traps

| Trap | Fix |
|---|---|
| 10 courses, 0 projects | Force one project per course — uncompleted projects = zero value |
| Urge to switch language mid-track | Track chosen in week 3 is locked through week 11 |
| Interview answers stuck at "I studied X" | Lead with project trade-offs and decisions you made |
| Resume = certs + courses list | Rewrite around quantitative results (users, revenue, perf) |

## What JOB.HELP gives you along the way

The tools learners hit most during these 90 days:

- **[/match](/match)** — interview and cover-letter guides (Phase 4)
- **[/resume](/resume)** — local resume/job-description phrase comparison; not an official ATS score or hiring prediction
- **[/tools](/tools)** — AI playbooks per profession (developer edition)
- **[/agents](/agents)** — review/test/CI agent catalog

Ninety days is short. Reduce scope and leave a working artifact every week. The final test is not whether you can call yourself a developer, but whether you can explain your design choices and failure record in your own words.
