I'm Jibran Usman, a Ruby on Rails developer who loves building robust, scalable web applications and shipping open source tools that solve real production problems.
| Gem | What it does | Downloads |
|---|---|---|
| turbo_presence | Figma-style live cursors, avatar stacks, and typing indicators for Rails/Hotwire |  |
| webhook_inbox | Transactional inbox for Rails webhook receivers — deduplication, async processing, replay, dashboard |  |
| llm_cassette | VCR for LLMs — streaming-aware cassette recorder for OpenAI and Anthropic |  |
| promptscrub | Bidirectional PII redaction for LLM calls — strip sensitive data from prompts, rehydrate in responses |  |
| http_decoy | A real Rack server that runs inside your RSpec tests — test HTTP contracts, not assumptions |  |
| agent_jail | Fork-based sandbox for LLM tool calls — timeout, memory limit, and filesystem restrictions |  |
Here are some of the technologies and tools I use frequently:
- Ruby on Rails
- Apache Kafka
- GraphQL
- Docker
- Elasticsearch
- Sidekiq
- Redis
- RSpec
- Capybara
- Hotwire / Turbo / Stimulus
I love coding because it allows me to turn my ideas into reality. Whether it's building a new feature, optimizing an existing one, or creating a new application from scratch, I find coding to be both challenging and rewarding.
Ruby on Rails is my preferred framework because it allows me to create web applications quickly and efficiently. I also enjoy working with other tools and technologies, like Apache Kafka for real-time message processing, GraphQL for efficient data retrieval, Docker for containerization, Elasticsearch for fast and flexible search, Sidekiq and Redis for background processing, and RSpec and Capybara for testing and integration.
