Multi-Marketplace Integration Suite

Shein · Google Shopping · Mirakl — at scale.

Production integrations with flaky third-party marketplaces. Idempotent webhook ingestion, schema-versioned mapping layer, retry windows with DLQ, rate-limit aware schedulers. The substrate every agentic AI tool eventually needs.

Deep Dive · 01

Production-Grade Retrieval-Augmented Generation (RAG)

Most GenAI applications fail at scale because they rely on naive 'retrieve-and-generate' defaults. I engineer Advanced RAG pipelines designed for enterprise precision and low-latency data access.

  • Hybrid Retrieval & Reranking

    Moving beyond simple cosine similarity. I implement parallel hybrid search (Dense embeddings + BM25) fused with Reciprocal Rank Fusion (RRF), followed by cross-encoder reranking to ensure high-fidelity context windows.

  • Dynamic Query Optimization

    Implementing advanced routing, HyDE (Hypothetical Document Embeddings), and step-back prompting to close the vocabulary gap between user intent and unstructured document text.

  • Scalable Vector Infrastructure

    Proficient in deploying and tuning vector databases like Weaviate, Qdrant, and Pinecone, balancing indexing speed, chunking strategies (semantic vs. token-based), and query latency for production loads.

Agentic Workflows & Multi-Agent Orchestration

True AI value isn't in stateless chatbots; it's in autonomous systems that can plan, execute, and course-correct. I leverage my deep background in SaaS architecture to build reliable Agentic AI frameworks that bridge the gap between LLM reasoning and real-world execution.

  • Execution & Tool Use

    Grounding intelligence in reality. I build AI agents equipped with Model Context Protocol (MCP) integrations, enabling them to securely execute API calls, query SQL/NoSQL databases, and interact with complex SaaS ecosystems (WooCommerce, CRMs, Stripe).

  • Stateful Orchestration & Memory

    Utilizing frameworks like LangGraph to map agent behavior as a state machine. I manage durable execution, short/long-term memory persistence, and human-in-the-loop guardrails for mission-critical workflows.

  • Advanced Reasoning Patterns

    Implementing ReAct (Reasoning + Acting), self-reflection loops, and Evaluator-Optimizer topologies to drastically reduce hallucination rates and increase autonomous task success.

5 years of shipping SaaS is the moat.

Most AI engineers can write a prompt. Far fewer can wire it into a multi-tenant, audit-logged, webhook-driven, billable enterprise system. This timeline reframes my SaaS years as the engineering backbone for production-grade AI.

WooCommerce & SaaS foundations

PHP plugins, WP hooks, theme architecture.

Started shipping production WooCommerce systems — extensions, custom checkout flows, plugin architecture. Learned where real systems break: hooks, edge cases, customer data weirdness.

Marketplace API integrations

Shein · Google Shopping · Mirakl.

Integrated flaky third-party marketplaces at scale — Shein, Google Shopping, Mirakl. Pagination quirks, rate-limit dances, schema drift. Translation: I already know how to negotiate the kind of unreliable APIs that LLM-tooling engineers will meet in production.
