Atlassian's revenue: $1.79 billion last quarter
Atlassian's move: fire the engineer who built their infrastructure
his move: post a 38-minute breakdown of every system he built, free for anyone to copy
what he revealed:
> Envoy proxy instead of enterprise load balancers
> sidecar architecture for auth, logging, rate limits
> DynamoDB + SQS for async provisioning
> Packer + SaltStack for automated VM deployments at scale
Atlassian charges per employee across 350,000 customers
this guy just handed you the enterprise playbook for free

You're in a backend interview.
They ask:
"Design a distributed rate limiter that enforces per-user and per-IP request limits across 100+ API servers."
Here's how to approach it:

🚨 STOP BURNING YOUR TOKENS!
If you use Claude Code, you are probably wasting 80% of your context window.
I found 10 ace tools that will completely rescue your API bill.
1. Caveman Claude
- Literally makes Claude talk like a caveman
- Slashes 75% of output tokens with zero loss in accuracy
Repo → https://t.co/eEvSOvHutG
2. RTK (Rust Token Killer)
- A blazing fast proxy that filters terminal output
- 60-90% reduction and completely dependency-free
Repo → https://t.co/lDfjbsbPD5
3. Code Review Graph
- Claude reads only what matters using a Tree-sitter graph
- An unbelievable 49x token reduction on huge monorepos
Repo → https://t.co/xGn6Pp88yX
4. Context Mode
- Sandboxes raw output into SQLite instead of your context
- A staggering 98% context reduction on logs & GitHub
Repo → https://t.co/Jut2bvBMUD
5. Claude Token Optimizer
- Brilliant setup prompts that optimize any project
- 90% token savings, taking docs from 11K to 1.3K
Repo → https://t.co/0uOFODbG7e
6. Token Optimizer
- Hunts down the invisible ghost tokens eating your context
- Fully restores and protects your context quality
Repo → https://t.co/LUOzjECXKm
7. Token Optimizer MCP
- Adds aggressive caching and compression to your MCP tools
- 95%+ token reduction through pure intelligence
Repo → https://t.co/b5Eqruo2PM
8. Claude Context
- Zilliz’s hybrid vector search MCP
- Makes your entire codebase the context for 40% less cost
Repo → https://t.co/hPG6pb0j3G
9. Claude Token Efficient
- Just drop one CLAUDE.md file into your repo
- Enforces strict terseness with zero code changes
Repo → https://t.co/fNrl6nwItF
10. Token Savior
- Navigates your code by symbols, not giant files
- 97% reduction on code navigation with persistent memory
Repo → https://t.co/lkILPhfwJh
----
[ The god-tier stack ]
Pick 2-3 based on what’s draining you:
> Massive repo? Code Review Graph + Token Savior
> Heavy terminal output? RTK
> MCP data dumps? Context Mode
> Need an instant fix? Caveman + Claude Token Efficient
Most devs are bleeding tokens.
Run `/context` in a fresh session and watch the savings roll in 👀

REAKING: Someone built a visual guide to master Claude Code in a weekend.
It's called Claude How-To and it's the fastest way to go from zero to orchestrating agents, hooks, skills, and MCP servers.
Here's what's inside:
→ Visual tutorials you can actually follow
→ Copy-paste templates ready to use
→ A guided learning path from beginner to advanced
→ Full feature catalog to browse what's possible
→ Get started in 15 minutes literally
Just a clean, structured path to using Claude Code like a pro.
