Sentinel
Policy check → allow · deny · hold for a human → audited
FeaturedAI Infra
Sentinel
The approval layer for AI agents that take action. Every high-risk tool call is put through policy before it runs — allow, deny, or hold for a human — with a full audit log, request traces, cost tracking, and an eval CI gate.
FastAPIPythonSQLAlchemyPostgreSQLRedisNext.jsTypeScriptClerkTailwind
Key features
- Policy gateway: allow / deny / hold on every tool call
- Human-in-the-loop approvals for high-risk actions
- Immutable audit log of every decision
- Request traces, cost tracking & an eval CI gate
Architecture
- FastAPI policy engine in front of agent tool calls
- SQLAlchemy + Postgres (SQLite for local dev)
- Redis for rate-limit windows
- Next.js + Clerk dashboard for approvals & audit
CRO Engine
Shopify URL → scrape → evidence → ranked audit
FeaturedAI · Commerce
Shopify CRO Engine
Paste a Shopify store URL and get a prioritized, evidence-backed conversion-rate-optimization audit. An LLM works over the store's real catalog and page content, so every recommendation cites actual products and copy instead of generic best-practice advice.
Next.jsReactTypeScriptClaude + GeminiCheerioZodRechartsVitestTailwind
Key features
- Paste a store URL → prioritized CRO audit
- Recommendations cite real products & on-page copy
- Each opportunity scored: impact · confidence · effort
- Suggested experiment + expected lift per finding
How it works
- Scrape the store (Shopify JSON + cheerio)
- Extract on-page evidence
- LLM ranks opportunities (Claude/Gemini + fallback)
- Render an evidence-backed, prioritized audit
FlowCare AI
Referral → OCR → AI extraction → scheduled patient
FeaturedHealthcare AI
FlowCare AI
A production-grade healthcare referral-automation platform with a visual workflow builder. It turns any referral — PDF, fax, scanned image, or web form — into a verified, scheduled patient automatically, using OCR, LLMs, and a queue-based pipeline with a full audit trail.
FastAPIPythonPostgreSQLRedisCeleryClaudeTesseractTwilioNext.jsTypeScriptDocker
Key features
- Omni-channel intake: PDF, image, fax, web form
- OCR + Claude extraction with per-field confidence
- Drag-and-drop visual workflow engine
- Human-in-the-loop review & immutable audit trail
Architecture
- FastAPI API; heavy work runs in Celery workers
- Redis broker: retry → backoff → dead-letter queue
- PostgreSQL (14-table schema) + audit log
- JWT rotating-refresh auth, RBAC, multi-tenant
BugZero
Ralph AI → analyze → auto-PR
FeaturedAI SaaS
BugZero
An AI-powered autonomous bug-fixing SaaS that detects, analyzes, and fixes bugs in your codebase — integrating with GitHub to open pull requests without human intervention.
Next.jsReactTypeScriptClaude APIPrismaPostgreSQLNextAuthBullMQRedisGitHub API
Key features
- Ralph AI analyzes bugs using Claude
- One-click GitHub integration with webhooks
- Analytics dashboard for tracking fixes
- Command palette (⌘K) for power users
How it works

- An issue triggers a webhook
- AI analyzes and generates a fix
- A pull request is opened for review
Nomichi
Enquiry → live board → confirmed seat
FeaturedFull-stack CRM
Nomichi Trip Desk
A real-time CRM for a travel team. A public enquiry lands live on the team's board a second later and is walked from first hello to a confirmed seat — public site, admin pipeline, a trips CMS, and a dashboard, all sharing one source of truth.
Next.js 15TypeScriptSupabasePostgreSQLServer ActionsZodClaude + GeminiTailwind
Key features
- Public enquiry → live admin board, no refresh
- Pipeline, call log, owners & timeline
- Trips CMS drives what the public sees
- AI: draft WhatsApp, read the vibe, summarise
Engineering
- Reads as Server Components, writes as Actions
- Postgres enums + checks guard bad data
- Row-level security; keys stay server-side
- Provider fallback: Claude → Gemini → template
RealTime
CRDT editing · live cursors · presence
FeaturedSystems
RealTime Collaborator
A production-grade collaborative document editor — many people editing the same doc at once with instant conflict resolution, live cursors and presence, offline sync, and full version history. Architected to scale horizontally to thousands of concurrent connections.
ReactTypeScriptYjs / CRDTSocket.ioNode.jsExpressRedisDocker
Key features
- Multi-user editing with CRDT resolution
- Live cursors, selections & presence
- Offline support with auto-sync on reconnect
- Version history & collaborative undo/redo
Architecture
- Yjs CRDT over Socket.io with backoff
- Stateless services behind a load balancer
- Redis pub/sub fan-out across nodes
- TypeScript monorepo: client · server · shared
Job Queue
HTTP intake → priority queue → workers → retries · DLQ
FeaturedDistributed Systems
Distributed Job Queue
A background job queue for Go services. You hand it work over HTTP, a pool of workers runs it, and the queue handles the tedious parts: priorities, delays, retries with backoff, dead-lettering, and recovering jobs when a worker dies mid-execution.
GoGinPostgreSQLRedisDockerPrometheusOpenTelemetry
Key features
- HTTP intake; a worker pool runs the jobs
- Priorities, delays, retries with backoff
- Dead-lettering & recovery when a worker dies
- Metrics + tracing; single
docker compose up
Architecture
- Postgres is the system of record (every attempt a row)
- Redis is the priority-ordered queue
- At-least-once delivery with worker leases
- Prometheus metrics + OpenTelemetry traces
