CONCEPTS.UNLOCKED
🌐
Open Source
Contribute to software used by millions. Find a "good first issue," fork the repo, make a fix, submit a PR. Your contribution lives on in the codebase forever. This is how the industry works.
📄
PR Etiquette
Read CONTRIBUTING.md first. Follow the project's style. Write a clear PR description: what you changed and why. Be patient — maintainers are volunteers. Respond to feedback graciously. Your PR is your resume.
👤
Professional Profiles
GitHub, LinkedIn, and your portfolio tell your story. Pin PixelCraft on GitHub. Update LinkedIn with specific skills and accomplishments. Link everything together. Recruiters search these platforms daily.
📋
Resume Engineering
Show impact, not responsibilities. "Built auto-enhance feature reducing manual edits by 73%" not "Worked on image processing." Quantify everything. Match the job description's language. One page.
💰
Negotiation Basics
Never give the first number. Research the range. Negotiate total comp. Use levels.fyi for data. Salary is just one piece: equity, bonus, remote, growth, team quality. Know what matters to you before the conversation.
CAREER.TASKS
01
First Open Source Contribution
// Step-by-step: ## 1. Find a Project - github.com/topics/good-first-issue - Look for projects you actually USE: React, Vite, Zustand, Vitest, testing-library, MDN Web Docs - Filter: "good first issue" label - Pick something achievable in 1-2hrs ## 2. Understand the Project - Read README.md - Read CONTRIBUTING.md - Look at recent merged PRs (understand the style) - Set up the dev environment locally - Run the test suite ## 3. Fork, Branch, Fix git fork [repo] git clone [your-fork] git switch -c fix/issue-1234 # Make your changes # Run tests # Follow project's linting rules git commit -m "Fix typo in docs (#1234)" git push origin fix/issue-1234 ## 4. Submit PR - Reference the issue: "Fixes #1234" - Describe what you changed and why - Include screenshots if visual - Be patient: review may take days - Respond to feedback constructively ## 5. Celebrate // Your code is now in a project // used by thousands (or millions). // You're an open source contributor.
Good first contributions: Fix typos in docs (easiest). Add missing test cases. Fix a small bug. Improve error messages. Update outdated dependencies. These are all valuable and welcomed by maintainers.
02
Update Professional Profiles
// GitHub Profile: - Pin PixelCraft as #1 project - Write a profile README (github.com/[you]/[you]) - Ensure contribution graph shows consistent activity - Add topics/tags to PixelCraft repo // LinkedIn: - Headline: "Full-Stack Developer | React · TypeScript · Node.js" - About: 3-4 sentences about what you build and what excites you - Experience: add PixelCraft project with quantified accomplishments - Skills: React, TypeScript, Node.js, MongoDB, Docker, CI/CD, REST APIs // Portfolio Site (if you have one): - Hero: name + one-line identity - Projects: PixelCraft with live demo link, screenshots, case studies - About: your story + what you're looking for - Contact: email, GitHub, LinkedIn // Everything links to everything: // GitHub → Portfolio → LinkedIn // LinkedIn → GitHub → Portfolio // Portfolio → Live Demo → Case Studies
03
Resume: One Page, Impact-Driven
// Resume structure: ## [Your Name] Email | GitHub | Portfolio | LinkedIn ## SKILLS TypeScript, React, Node.js, Express, MongoDB, Redis, Docker, Git, CI/CD, Vitest, Playwright, REST APIs ## PROJECTS ### PixelCraft — Web-Based Image Editor github.com/you/pixelcraft | live demo - Built production-grade image editor with canvas-based editing, real-time filters, and auto-enhance feature - Improved gallery load time from 8.2s to 1.1s through lazy loading, WebP conversion, and code splitting - Designed plugin architecture enabling third-party filter extensions with sandboxed API and permission system - Achieved Lighthouse score of 94 and WCAG 2.1 AA compliance with zero accessibility violations - Implemented CI/CD pipeline: 200+ automated tests, Docker deployment, Sentry error tracking ## EDUCATION Break && Build Academy Full-Stack Development (128 sessions) // Rules: // - One page. Always one page. // - Quantify: numbers prove impact // - Action verbs: Built, Designed, // Improved, Implemented, Achieved // - Match job description language // - No "responsible for" — show impact
04
Career Discussion: Roles & Negotiation
// ROLES THAT MATCH YOUR SKILLS: Full-Stack Developer → Your strongest fit → React + Node.js + MongoDB + DevOps → Most PixelCraft skills transfer Frontend Engineer → If you loved the React/Canvas/UX work → Deeper: performance, accessibility, design systems, animation Backend Engineer → If you loved APIs/databases/DevOps → Deeper: distributed systems, queues, scaling, observability DevOps / Platform → If you loved Docker/CI/CD/monitoring → Deeper: Kubernetes, Terraform, SRE // NEGOTIATION BASICS: 1. Research the range first → levels.fyi, glassdoor, blind → Know the 25th/50th/75th percentile 2. Never give the first number → "What's the range for this role?" → "I'm flexible — what's budgeted?" 3. Negotiate total compensation → Base + bonus + equity + benefits → Remote flexibility has real value 4. Get it in writing → Verbal offers aren't offers → "I'm excited! Can you send the written offer?" 5. It's okay to ask for time → "Can I have until Friday to consider?"
05
Evaluating Companies & Teams
// Questions to ask in interviews: ## Engineering Culture "How do you do code reviews?" "What does your CI/CD pipeline look like?" "How do you handle incidents?" "What's your testing philosophy?" ## Team & Growth "How big is the team I'd join?" "Who would I learn from?" "What does the promotion process look like?" "What's the on-call rotation?" ## Product & Impact "What are the team's goals this quarter?" "How do engineers influence product decisions?" "What's the tech debt situation?" ## Red Flags to Watch For: ❌ "We don't really do code reviews" ❌ "We deploy manually" ❌ "There aren't many tests" ❌ "You'll figure it out" (no onboarding) ❌ Interviewer can't explain what the team is building ## Green Flags: ✅ Structured onboarding ✅ Regular 1:1s with manager ✅ Engineers choose their tools ✅ Blameless postmortems ✅ Interviewer is genuinely excited about their work
