Commerce engineering, AI integrations, and data-driven CRO.

I build Shopify storefronts, custom apps, and Checkout Extensibility solutions for DTC brands. I also design and implement AI-powered features from LLM integrations to automated workflows and apply rigorous behavioral data analysis and A/B experimentation to drive measurable conversion improvements. Recent work spans Patagonia, Perfect Snacks, Malbon Golf, and a 50% revenue lift at a US brand.

02 about

Engineer first. Data-driven when it matters.

Six years inside eCommerce first as a full-stack developer building Laravel and MERN platforms, then deep into the Shopify ecosystem: themes, custom apps, App Functions, Checkout Extensibility, and headless storefronts on Remix and Hydrogen.

Increasingly, my work intersects with AI: I integrate large language models and retrieval-augmented generation pipelines into commerce workflows, build automated data-processing agents, and apply AI-assisted tooling to accelerate CRO hypothesis generation and analysis. I treat AI not as a novelty, but as infrastructure for more intelligent, responsive storefronts.

I work best when I own a problem end-to-endf architecture, implementation, performance, and the conversation with whoever will use it. I write clean code, mentor junior developers, and care about shipping over shipping perfectly.

04 ai & data

AI engineering and data-driven conversion science.

Applying AI, behavioral analytics, and rigorous experimentation to commerce outcomes.

AI Engineering & LLM Integration

I design and implement production-grade AI features for eCommerce — from OpenAI and Anthropic API integrations to retrieval-augmented generation (RAG) pipelines, conversational agents, and AI-assisted product discovery. Each integration is built for reliability, latency targets, and measurable business impact rather than novelty.

Behavioral Data Analysis & Insights

I conduct structured behavioral analytics — cohort analysis, funnel diagnostics, session analysis, and revenue attribution — using Python and modern analytics platforms. The deliverable is always a prioritized, evidence-backed set of actionable hypotheses, not raw dashboards. Data informs every decision before a single line of code is written.

Python Pandas GA4 Mixpanel Segment Cohort Analysis Funnel Diagnostics
A/B Experimentation & Statistical Analysis

End-to-end ownership of the experimentation lifecycle: hypothesis formulation grounded in behavioral data, variant design, implementation, and rigorous statistical significance analysis — including both frequentist and Bayesian methods. Every test concludes with an executive-level report mapping results directly to revenue impact. 30+ validated experiments shipped across high-traffic DTC storefronts.

Conversion Rate Optimisation (CRO)

Systematic, data-led conversion optimisation — auditing the full purchase funnel from landing to post-checkout, identifying friction points through qualitative and quantitative evidence, implementing targeted interventions, and measuring impact with statistical rigour. This is the exact playbook that delivered a 50% year-over-year revenue lift at a US Brand.
