10+ LinkedIn Post Examples for Software Engineers (2025)

Example:

Just learned something that blew my mind about React's useEffect hook.

Most developers (including me) use dependency arrays incorrectly. Here's what I discovered:

• useEffect runs AFTER the browser paints, not before
• Missing dependencies can cause stale closures
• useLayoutEffect is better for DOM measurements

The React docs explain this, but I never fully understood until I debugged a production bug.

What's a technical concept that clicked for you recently?

Example:

🚀 Excited to share that we just launched [Project Name]!

After 3 months of development, our team shipped a feature that reduces API response time by 60%.

Here's what we did:

• Implemented Redis caching layer
• Optimized database queries (removed N+1 problem)
• Added CDN for static assets

The best part? We did it without breaking existing functionality. Zero downtime deployment using feature flags.

Shoutout to [teammate names] for the collaboration!

Example:

Today marks 2 years at [Company Name]. Time flies when you're building cool stuff.

Looking back, I'm grateful for:

• Mentoring junior developers (taught me patience)
• Leading the migration to microservices (learned a lot)
• Working with an incredible team

The biggest lesson? Code is temporary, but relationships and knowledge last forever.

To everyone who helped me grow: thank you. 🙏

Example:

Spent 8 hours debugging a production issue yesterday. Here's what happened:

The Problem: Our API was randomly returning 500 errors for 2% of requests. No pattern, no logs, just chaos.

The Investigation:
• Checked error logs (nothing)
• Reviewed recent deployments (clean)
• Added more logging (still nothing)

The Solution: Memory leak in our connection pool. Under high load, connections weren't being released properly.

Fixed it by implementing proper connection lifecycle management and adding monitoring.

Lesson: Sometimes the bug isn't in your code, it's in how your code interacts with infrastructure.

Example:

Just discovered [Tool Name] and it's a game-changer for [use case].

Before: [describe the pain point]
After: [describe the improvement]

What I love:
• [Feature 1]
• [Feature 2]
• [Feature 3]

Example:

Hot take: Not every project needs microservices.

I've seen teams break apart monoliths prematurely, only to create more problems:

• Increased complexity
• Network latency
• Deployment headaches

Start with a monolith. Split when you have a real reason (team scaling, performance, etc.).

What's your experience? When did microservices make sense for you?

Example:

What engineering actually looks like:

• 2 hours: Reading documentation
• 1 hour: Writing code
• 3 hours: Debugging why it doesn't work
• 30 minutes: Realizing you had a typo
• 10 minutes: Fixing the typo
• 1 hour: Writing tests

The code that ships is 10% of the work. The other 90% is thinking, debugging, and learning.

If you're stuck on something, remember: this is normal. Keep going.

Quick tip for developers:

Always add a README to your projects. Even if it's just:

• What it does
• How to run it
• Key dependencies

Future you (and your teammates) will thank you.

What's a small habit that made a big difference in your workflow?

Example:

Just finished "[Book Name]" and it changed how I think about [topic].

Key takeaways:
• [Takeaway 1]
• [Takeaway 2]
• [Takeaway 3]

If you're interested in [topic], this is a must-read.

What's the best technical book you've read this year?

Question for the engineering community:

How do you balance code quality with shipping speed?

I've seen teams go both ways:
• Ship fast, refactor later
• Perfect code, slower delivery

What's your approach? When do you prioritize speed vs. quality?
