Projects

CodeHalcon

View Project
Node.jsFastifyPostgreSQLRedisLlama 3.3 70B
  • Built a production GitHub App that automatically reviews pull requests using Llama 3.3 70B — posts severity-tagged inline comments directly on code diffs, reducing manual review overhead.
  • Solved duplicate-processing under webhook retries using idempotent PostgreSQL pipelines with token-aware diff chunking, ensuring reliable and deterministic LLM input.
  • Secured webhook ingestion with HMAC signature verification; implemented exponential backoff retry logic and a failure-safe processing architecture to handle LLM provider downtime gracefully.

AsyncGuard

View Project
TypeScriptNode.jsVitestESMtsup
  • Designed and published a reusable TypeScript async reliability library — retry/backoff, timeout protection, AbortSignal-based cancellation, and fallback recovery for backend systems.
  • Built concurrency primitives including task pooling, queue size limits, and controlled parallel execution for high-throughput workloads.
  • Implemented a first-success race orchestrator to call multiple async providers in parallel and return the fastest successful result, with AggregateError propagation on total failure.
  • Packaged as ESM-ready with typed exports and a clean tsup build pipeline; tested with Vitest fake timers for deterministic, millisecond-level suite execution.

Expense AI

View Project
ReactNode.jsMongoDBGemini API
  • Built a fault-tolerant AI expense tracking app with a multi-model fallback pipeline, maintaining near-zero downtime during API provider failures.
  • Designed a recurring expense engine with deterministic scheduling and automated execution across billing cycles.
  • Generated monthly financial reports using MongoDB aggregation pipelines with AI-driven insights layered on top for contextual analysis.
