Life OS
Personal productivity system I built to run my life through conversation. Orchestrates Claude Code with native MCPs (Apple Reminders/Calendar, GitHub), 15 custom skills, 5 automation hooks, and semantic search (BM25 + SQLite FTS5). Pipes into Content Digest for a full knowledge loop and powers Career Ops for HITL automated job search.
Career Ops
HITL job search pipeline — AI periodically evaluates offers across 10 dimensions (A-F scoring), spins up ATS-optimized PDF resumes per listing, and pre-fills applications. I review, filter, and decide which ones to ship. Batch-processes 48+ offers in parallel (conductor + workers), scans portals with dedup, and adapts narrative framing per role archetype. Plugs into Life OS as a specialized skill.
santifer.io
Interactive CV with AI chat, shipped following an AI-augmented SDLC. Built with Claudeable, monitored with Claude Pulse, animations debugged with Claude Eye. Production LLMOps: Langfuse, 39 evals, prompt caching, 4-layer prompt injection defense (output filtering, canary tokens, fingerprint detection).
Claude Eye
CLI that analyzes web animation videos frame-by-frame using Claude Vision. Detects CSS transition desyncs and generates reports with exact timestamps.
Claudeable
Claude Code meta-project for professional web development. Custom skills, templates and pre-configured MCPs to build Lovable-quality websites.
Claude Pulse
SwiftBar plugin for real-time Claude Code usage monitoring on macOS. Consumption metrics, rate limit predictions, and context-aware tips.
Content Digest
Python + FastAPI service for LLM-powered content ingestion and digest generation. Winning prototype, now in production with enterprise best practices.
ProjectOS Predict
Risk prediction dashboard for project portfolios. ML model trained on synthetic data flags delays before they happen. Second capstone from Maven AI PM bootcamp (Marily Nika).
Claude Code Power User
High-Agency · AI-FluencyMy daily workflow is a multi-agent orchestration lab. The problems I solve (context management, inter-agent communication, memory persistence) are the same ones enterprise customers face.
- ›Multi-agent orchestration: 5+ specialized agents running in parallel via tmux, each with its own context, skills, and hooks
- ›Inter-agent IPC: async communication protocol between agents via JSON — they consult each other for cross-domain decisions
- ›Memory persistence: pre-compact hook that crystallizes knowledge with Haiku before each compaction — memory that survives sessions
- ›Reusable custom skills: automated deploy, tech translation, design systems, SEO, career consulting
