About

Engineering leader with 15+ years in eCommerce. Built and scaled engineering teams from technical execution through executive ownership — nearly 5 years on Head of Engineering and CTO roles, leading a 40+ person engineering organization. Areas where I create most value: — Engineering organization design. Restructuring teams, establishing tech lead ownership, RACI/PDP/KPI frameworks, hiring across senior and mid levels. Comfortable building from first hires up to 40+, or restructuring established teams under pressure. — Multi-platform eCommerce delivery. 14 years in eCommerce engineering, primarily Magento 1 and 2. Led the company's pivot from a single-stack Magento agency to multi-platform operation across Shopify, Shopware, and WooCommerce. Strong on delivery processes, quality gates, and crisis-tested cost optimization. — AI-driven product and engineering practices. Founded an AI product practice from scratch — production AI agents covering product discovery, upsell, customer support, accessibility, and content localization. SaaS-style platform integrated with OpenAI, Anthropic, Gemini, Mistral, DeepSeek. Internally, embedded AI tooling into engineering workflows, materially increasing team capacity without growing headcount. — Crisis management and cost discipline. Executed restructuring during 2023 market downturn — maintained delivery while substantially reducing fixed cost base. Currently exploring CTO / Head of Engineering / VP Engineering roles in companies scaling faster than they can build the team. Particularly interested in eCommerce, AI/ML products, and tech transformations. — Tech stack: — Backend: Node.js, PHP, MongoDB, MySQL, Redis, Elasticsearch — Frontend: React, Next.js, TypeScript, React Native — eCommerce: Magento 1 & 2, Shopify, Shopware, WooCommerce, headless/PWA — AI/ML: production AI agents, multi-LLM (OpenAI, Anthropic, Gemini, Mistral, DeepSeek), RAG (Qdrant + MongoDB, OpenAI embeddings), agent orchestration LLM security & reliability: prompt injection sanitization, per-tenant cost limits, output validation, audit logging, fallback chains for provider outages.
