Nothing cements skill like building. Work through these projects in your language of choice; each maps to a real capability and makes a great portfolio/GitHub piece.

1. Port scanner — TCP connect + banner grabbing + threading.
2. Directory/content scanner — wordlist-based, like gobuster/ffuf.
3. Password sprayer — one password across many users, with rate control.
4. Subdomain enumerator — passive (crt.sh/APIs) + brute force.
5. Custom reverse shell — TCP handler + client, then add encryption.
6. Web fuzzer — mutate parameters and detect anomalies.
7. Burp Suite extension — automate a repetitive check in your workflow.
8. Exploit automation — wrap a manual exploit into a one-command PoC.
