Projects

Each project is a path I've explored — some winding, some steep, all worth the journey.

Rules Engine

Evaluates complex user-defined schemas and rules

  • Designed a stateless, horizontally scalable rule engine evaluating dynamic user-defined schemas via Common Expression Language
  • Achieved ~7k RPS per instance under sustained load (10-minute test, ~4M evaluations)
  • Identified and analyzed saturation behavior at tail latencies (p95 ~2.8s under peak load)

Real-time Collaborative Markdown Editor

Real-time collaborative markdown editor powered by CRDTs

  • Built real-time collaborative editing using Automerge CRDTs for conflict-free merging and eventual consistency across users
  • Supports live markdown rendering so collaborators can preview changes as they write
  • Implements threaded comments with replies and resolution for inline discussion
  • Tracks user presence and cursor positions in real time, showing who's active in the document

Automerge Sync Daemon

Rust CLI daemon that syncs local files with a remote Automerge document

  • Connects to an automerge-repo WebSocket sync server and keeps a local file in sync with a remote Automerge document
  • Implements the full automerge-repo handshake and CBOR-encoded message protocol
  • Handles ping/pong keepalive and graceful shutdown

Distrace

Distributed tracing backend for OpenTelemetry

  • Correlates out-of-order spans across services using TraceID grouping and parent–child resolution
  • Implements bounded trace completion with inactivity and max-age limits (30s / 5m) to balance completeness with memory constraints
