Experience
Founder & Agent Architect - ConnectXeo
(2025-01)
- Architected the multi-agent system from scratch — coordinator-subagent pattern with 7 specialized agents, each owning isolated tool scopes, error boundaries, and retry logic across 40+ live Shopify API integrations
- Defined and enforced architectural standards for agent-to-agent communication, state management, and tool-call routing — reusable patterns now governing every subsystem on the platform
- Reviewed agent design decisions across multiple project domains (orders, refunds, inventory, draft orders) — ensuring each subagent scales independently behind consistent contract interfaces
- Built multi-tenant infrastructure with per-merchant agent isolation, shared orchestration patterns, and multi-channel deployment (WhatsApp Business Cloud API, web chat, REST API)

- Sole backend architect on a production content automation platform — designed multi-stage agent orchestration: automated topic discovery → relevance scoring → LLM outline generation → human-in-the-loop approval → SEO-optimized publishing
- Engineered async state persistence with PostgreSQL + Alembic migrations and Redis-based workflow orchestration, ensuring pipeline reliability under production load
AI Engineer - Emulxion.ai
(2024-01 - 2024-11)
- Designed advanced RAG architecture with multi-query expansion, query decomposition, fusion, and intelligent reranking — established the retrieval pattern adopted across the engineering team
