Things I've built and shipped

15 years of building systems that scale, teams that ship, and platforms that last. Here's a look at the work that shaped my career.

# Featured Work

# Other Work

## Infrastructure & Scale

  • Global Microservices Migration — Drove a multi-year transition from monolith to microservices across 8+ teams. Defined target architecture, migration playbook, and coached teams through adoption. Deployment frequency went from weekly to multiple times daily.
  • Multi-Region Database Architecture — Designed sharding and replication strategies for global user base. Achieved consistent sub-50ms query latency across regions.
  • Payments & Reliability — Architected multi-provider payment system for mission-critical transactions. 99.99% uptime with automatic failover and reconciliation.

## Data & MLOps

  • Petabyte-Scale ETL Platform — Built and maintained data pipelines handling petabytes from Databricks, BigQuery, Snowflake, and more. Enabled self-service analytics for business teams.
  • MLOps for Data Science — Created end-to-end pipelines letting data scientists train, evaluate, and deploy models to production without DevOps handoffs. Reduced model deployment time from weeks to hours.

## AI & Conversational Systems

  • AI Support Agent for Payments & Subscriptions — Building an AI-powered support chatbot for a SaaS startup in the payments and subscription billing space. The system answers complex merchant queries using real customer data — transactions, billing history, subscription states — where accuracy is critical and hallucinations aren't an option.
  • Advanced RAG Pipeline Architecture — Designed the retrieval-augmented generation system powering the chatbot. Multi-source context retrieval, semantic chunking, hybrid search (vector + keyword), and strict grounding to ensure responses are accurate and traceable to source data.
