A FEW THINGS I'VE SHIPPED
Falcon CRO — Shopify behavioral analytics (Node.js, Redis, BullMQ, React)
The server was throttling and dropping payment events during sales spikes.
I rebuilt the async processing layer with BullMQ, implemented idempotent
event and payment handling, and configured PM2 cluster mode for horizontal
scaling. P50/P90 latency improved 3× and core web vitals improved 8× for
their Shopify App Store submission.
SFMC Studio — Salesforce analytics platform (Next.js, MongoDB, AWS EC2)
Inaccurate metrics and slow aggregation pipelines were causing reporting
errors downstream for enterprise clients. I rebuilt the Salesforce Cloud
data ingestion with queue-based processing for safe, accurate delivery to
MongoDB and restructured the aggregation layer. Metrics accuracy improved
5× and web vitals improved 2–3×.
Custom AI-Powered CRM — Lending business, Irvine CA
(GPT-4o, NestJS, Aircall, Twilio, Zillow API, PostgreSQL, Azure)
Started on frontend, grew to full-stack ownership. Shipped modules for
AI-assisted lead management, Aircall call integration, Zillow property
enrichment, webhook processing, and Google Calendar + Outlook sync.
Lexilift AI — My own RAG SaaS
(Supabase, Pinecone, Voyage AI, GPT-4o, Claude Sonnet 3.5, Next.js)
Designed and built the full ingestion and query pipeline from scratch —
document chunking, vector embedding, context retrieval, and streaming
query API — for a multi-domain business knowledge base.
