Writing and Blogging as Career Insurance
TL;DR
- Technical writing = proof you can think and communicate. Hiring managers read it. One great post can outlast job changes. Evergreen career equity.
- 2026 hot topics: RAG in production, AI cost management, brownfield AI, chunking strategies. Write what you're learning—it compounds.
- Platform matters less than quality. Pick one. Post consistently (even if that's quarterly). Substack, Dev.to, Hashnode all work.
Your blog is a portfolio of your thinking. When you're not in the room, your words represent you. Personal branding, visibility, and public building align with "write your own ticket in 18 months"—differentiate through visible AI work and human skills (2026 AI Career Playbook).
Why It Works
- Demonstrates expertise. "I wrote about this" = you've thought it through.
- SEO for your career. People search "how to X" — your post shows up. So do you.
- Interview prep. "I saw your post on Y. Can you elaborate?" — you've already done the thinking.
- Recruiter magnet. Good technical content gets shared. Recruiters find it.
What to Write About
| Type | Example | Effort |
|---|---|---|
| How we fixed X | "How we reduced our API latency by 60%" | Medium |
| Lessons learned | "5 things I'd do differently building RAG" | Low |
| Technical deep-dive | "Chunking strategies for RAG" | High |
| Comparison | "LangChain vs raw API for our use case" | Medium |
| Tutorial | "Add semantic search to your app in 30 min" | Medium |
Write what you know. Write what you're learning. Write what you wish existed when you started.
Platforms
- Personal blog (Substack, Ghost, etc.): You own it. Full control. Best long-term.
- Dev.to, Hashnode: Good reach. Dev audience. Easy to start.
- Medium: OK. Algorithm can bury you. Use if you already have audience there.
- Company blog: Good for credibility. You don't own it. Supplement with personal.
Pick one. Stick with it. Cross-post if you want, but have a home base.
Cadence
- Ideal: 1–2 posts per month. Steady compounds.
- Realistic: 1 post per quarter. Still valuable. One strong post > 12 weak ones.
- Minimum: 1 post per year. Something is better than nothing.
No blog. No portfolio of thinking. Hiring manager: 'Can they communicate? Can they think through hard problems?' Unclear. Interview is the first test.
