I architect backend systems that scale and don't break under load.
6+ years building high-performance, fault-tolerant backend systems on Node.js and AWS serverless — and the marketplace integrations that move data across them at scale.
I'm a backend engineer who likes the unglamorous parts: idempotent pipelines, dead-letter queues, schema design, and APIs that behave under pressure.
At Threecolts I architect white-label SaaS connectors for the Mirakl ecosystem and build event-driven Node.js + PHP services on AWS that process high-volume e-commerce data across Amazon, eBay, Walmart, Etsy, Shopify, WooCommerce and Mirakl. Before that, I led a 4-person team at Cedcoss shipping WooCommerce marketplace plugins published to WordPress.org.
Lately I've been going deep on AI-powered automation — building LLM-based agentic systems and custom MCP servers with the Claude API for automated log analysis and error resolution, and thinking a lot about context engineering.
I like owning a problem end-to-end, from the architecture diagram to the production dashboard.
- Architected multiple white-label SaaS connectors for the Mirakl marketplace ecosystem — SFCC, Otto, WooCommerce & BigCommerce — handling 1M+ catalog items synced across platforms, owning AWS architecture and database schema design.
- Contributing to ChannelReply, a helpdesk-marketplace integration platform that has processed 100M+ messages across Amazon, eBay, Walmart, Etsy, Shopify, WooCommerce & Mirakl into Zendesk, Freshdesk & Gorgias.
- Led the evolution of ChannelReply's core service from a monolith to microservices, incrementally decomposing critical workflows without disrupting live production traffic.
- Shipped major API upgrades to the integration layer with zero disruption to live marketplace-to-helpdesk connections, using backward-compatible versioning and phased rollouts.
- Built a bulk email ingestion pipeline using AWS SNS & SES to route high-volume marketplace emails into helpdesk ticketing systems reliably.
- Designed Node.js + PHP microservices on AWS (Lambda, API Gateway, SQS, DynamoDB) for high-volume e-commerce data processing.
- Optimized data pipelines handling 10K+ records/batch, reducing API latency by 30–40% via queue-based decoupling and schema/index tuning.
- Built and own the CI/CD pipeline (GitHub Actions) for a production SaaS project, covering automated testing, build & deployment.
- Engineered LLM-based agentic systems with the Claude API for automated log analysis and error resolution.
- Led a 4-person team developing WordPress/WooCommerce marketplace integration plugins published to the WordPress.org repository.
- Designed and built the Shopify MCF connector as an independent microservice for order fulfillment (PHP + Node + MongoDB), decoupled from the core monolith.
- Used Redis for caching, session management, and rate limiting across high-traffic integration services, cutting redundant database load.
- Designed and optimized complex MySQL & MongoDB queries and indexing strategies at scale, improving system performance and stability by 25%.
- Implemented robust error handling, logging, and debugging for high-concurrency production systems.
