Senior AI Agent Engineer for Personal Secretary & Content Filtering Engineer

Seeking a senior AI Agent Engineer to build a personal autonomous AI secretary on my own server. The system should use OpenClaw or a suitable alternative, with WhatsApp as the main interface and voice/phone support if possible. The AI should learn about me over time, remember projects, goals, habits, preferences, appointments and tasks, and proactively support me like a real secretary. Key features include WhatsApp text/voice, long-term memory, calendar, tasks, reminders, planning, email drafting with WhatsApp approval, scheduled messages, server access, SSH, Linux, Docker, Git, APIs, databases, Python, Bash, C/C++, Rust, web/browser automation, coding, testing, debugging and deployment. Sensitive actions require my confirmation. Additionally, I need a robust solution to block adult content completely on my Android phone and laptop. Websites, images, thumbnails, videos and similar content should be detected and blocked, including content where the website text itself does not indicate adult content. I am especially interested in an AI-based local or network-level content classification system that can analyze visual content in real time and block it before it is displayed. DNS/firewall filtering alone is not sufficient. The solution should work across browsers and apps as far as technically possible, be difficult to bypass, secure and privacy-conscious. The complete system must be self-hosted, documented and transferable to me. Please share examples of similar projects.
