8.8 Full Portfolio Development

What you're building: A coherent professional identity — a portfolio that tells a single clear story and provides concrete evidence of the claim you're making about yourself as a practitioner.

Build a complete, cohesive public portfolio that positions you for a red team operator role.

Technique: Professional Brand Building

Tools/Templates: LinkedIn, Personal Blog, GitHub Profile

Procedure:

### 90-Day Content Plan

- **Month 1:**
  - Publish 2 technical writeups on retired HTB machines (focus on AD techniques)
  - Update LinkedIn with current certifications, skills, and a portfolio link
  - Pin your best GitHub repo to your profile

- **Month 2:**
  - Release 1 original tool or significant update to an existing one
  - Write 1 technique deep-dive (not machine-specific — evergreen content)
  - Engage in 3 community discussions (GitHub issues, Discord, blog comments)

- **Month 3:**
  - Audit all public profiles for consistency (handle, bio, photo, contact)
  - Contribute to one open-source offensive security project
  - Write a "lessons learned" post from a recent engagement concept (sanitized)

Portfolio Audit Checklist

• Consistency: Blog, GitHub, and LinkedIn use the same professional handle and bio
• Narrative: Bio clearly states your focus ("Red Team Operator specializing in AD exploitation and payload development")
• Accessibility: Best writeups are pinned on blog or GitHub — a recruiter can find them in 10 seconds
• Contact: Easy for a recruiter to find your email or LinkedIn direct message
• Freshness: At least one post or commit in the last 30 days
• Depth: At least one writeup that demonstrates deep technical understanding (not just a walkthrough)
• Breadth: Content spans at least 2 of the 8 pillars (e.g., AD exploitation + EDR evasion)

Narrative Cohesion

• The Story: "I am a specialist in Active Directory exploitation and Windows payload development."
• The Evidence: Certs (CRTO, OSCP), Tools (original tooling on GitHub), Writeups (AD attack chains, ADCS abuse).
• The Proof: Active GitHub contributions (green squares), community presence, engagement with others' work.
• The Goal: Every piece of content should reinforce the same professional identity — no scatter.

NOTE: Consistency beats volume. One high-quality, technically deep writeup per month outperforms five surface-level posts per week. Quality content gets referenced by others — that's the signal employers look for.

Public Portfolio Checklist

• Blog / digital garden with 5+ technical writeups published
• GitHub with 2+ original offensive tools (not forks)
• At least 2 certifications visible (CRTO, OSCP, CRTE, CRTL, or equivalent)
• HTB or THM profile showing medium/hard machine completions
• LinkedIn updated with red team-specific skills and certs
• At least 1 CVE, bug bounty, or responsible disclosure credit
• Active community presence (Discord, GitHub contributions)
• One "signature" writeup or tool that gets referenced by others
