AI & LLM Ecosystem
I'm deep into the AI-augmented development workflow — not just using these tools, but understanding how they fit together and building on top of them.
- Building SheLLM to unify LLM subscriptions behind a single API
- Daily driver of Claude Code, Copilot, and AI-powered skills & plugins
- Exploring Google Stitch, OpenAI Codex, and how agentic workflows reshape development
- Believer that AI is a multiplier, not a replacement — the craft still matters
Tech Stack
What Drives Me
- Designing scalable APIs and layered architectures that don't collapse under their own weight
- Exploring Rust for performance-critical systems and Python for AI & automation
- Building tools that make developers' lives easier — and using AI to get there faster
- Firm believer that continuous learning and clean code aren't optional — they're the baseline
