Projects & Open Source

Things I've built and contributed to.

Open Source Work

2026

Fixed a race condition in vtgate where concurrent goroutines accessed PreSessions, ShardSessions, and PostSessions during Rollback/Release flows
Introduced safe snapshot helpers for thread-safe iteration
Validated the fix with Go's race detector

2026

Resolved a critical frontend performance issue caused by excessive history.replaceState() calls during rapid scrolling
Designed a rate-limited history wrapper with debouncing and deduplication, eliminating browser SecurityError crashes while preserving URL sync and TOC highlighting
Improved docs navigation by adding dropdown indicators for nested sidebar items
Fixed an incorrect API duration example so docs matched supported formats

Dec 2025 - Feb 2026

Built a distributed search system in Go indexing 24K+ Wikipedia documents across 8 shards
Achieved 28ms p99 latency at 7K+ QPS through parallel query execution and multi-layer caching
Designed a hybrid ranking pipeline combining BM25 and vector similarity with 384-dimensional embeddings
Implemented an 8-node sharded architecture with etcd-based service discovery and fault-tolerant coordination
Engineered a parallel fan-out / Top-K merge query engine, reducing end-to-end latency by 12x compared with single-node search
Added Redis caching with distributed locking using SetNX to prevent thundering herd behavior under high concurrency
Deployed a 15-service Docker cluster for reproducible, production-like environments

Feb 2026 - Present

Built a Git-inspired schema versioning system using a commit DAG for branching, merging, and reproducible database history beyond linear migrations
Implemented DFS cycle detection and merge-base computation to preserve correctness under complex histories
Designed a deterministic ancestry engine using BFS with stable ordering, eliminating nondeterministic schema resolution across environments
Developed a three-way merge engine with structured diffs and typed conflicts instead of fragile text merges
Built schema diff and migration generation with topological sorting over foreign-key dependencies
Implemented live schema capture through PostgreSQL catalog introspection and a canonical DDL pipeline
