Architecture & Design: Design high-scale, distributed architectures bridging PHP (Laravel/Symfony) with LLM APIs and local model runtimes.

RAG & Vector Search: Build end-to-end RAG pipelines, including chunking strategies, embeddings, hybrid search, and vector database integrations (pgvector, Pinecone, Qdrant).

Pipeline Engineering: Architect reliable, asynchronous ETL workflows and message queues (Kafka, RabbitMQ, Redis) for data ingestion and indexing.

AI Governance & Optimization: Implement prompt engineering, semantic caching, token cost optimization, and output guardrails.

Technical Leadership: Define technical blueprints, lead system reviews, and mentor senior engineering talent.

3+ years in a Lead or Software Architect capacity designing distributed, high-throughput systems.

2+ years of production experience building LLM-powered features and RAG pipelines.

Strong hands-on experience with vector databases (pgvector, Pinecone, Milvus, Qdrant) and relational databases (PostgreSQL/MySQL).

Proficiency in event-driven systems, asynchronous processing (queues/workers), and API design (REST, gRPC, SSE).
