I’ve spent the last 20 years turning complex business puzzles into clean, high-performance software.

I’m a big believer in the Unix philosophy: keep it simple, make it efficient, and ensure it works beautifully with others.

• Core Stack: TypeScript, Node.js, Redis, AWS, ZeroMQ
• API Design: GraphQL (Apollo Server), REST.
• Infrastructure: Kubernetes, Docker, Ansible, CircleCI, Serverless.
• Database Design: MongoDB, PostgreSQL, ElasticSearch
• AI/Data: RAG (Retrieval-Augmented Generation), Neo4j (Knowledge Graphs), Qdrant.
• Legacy Expertise: Ruby, Ruby on Rails, RubyGrape, RSpec

A specialized library for transforming unstructured text into Knowledge Graphs for enhanced AI retrieval (RAG).

• Architecture: Combines Neo4j for relationship mapping and Qdrant for vector embeddings.
• Value: Solves the context-limitation of standard vector search by providing LLMs with structured entity-relation data.
• Stack: Node.js, Neo4j, Qdrant, Docker, OpenAI API.

• Contributor: Stripe, GraphQLAutotest, Stackreduce.
• Creator: * Garfield: A GraphQL Policy engine for secure schema access.
  • jsonLogic-GraphQL-Query: Logic-based querying for flexible GraphQL APIs.
  • RunLater, Reportly, CheckoutTo, Notify.js.

When I’m not architecting systems, you’ll probably find me:

• 🥾 Hiking mountain trails and exploring hidden landscapes.
• 🍳 Cooking and experimenting with fermentation in my kitchen.
• 🎧 Mixing music or diving into a good book.
• 🧘 Practicing a bit of yoga to stay balanced.
