Freelance Senior Software Engineer

Building commerce systems
that actually scale.

01 — ECOMMERCE

Ecommerce Engineering

End-to-end storefront and backend development — from custom Shopify apps to bespoke ecommerce platforms built for performance and scale.

Headless Commerce

Decouple your frontend from your commerce engine. I design and build headless architectures using modern APIs, giving you full control over UX.

Design, build, and containerise scalable microservices — including API gateways, event-driven systems, and service mesh configurations.

04 — INTEGRATIONS

Third-Party Integrations

Seamlessly connect your ecommerce stack with ERPs, CRMs, payment gateways, logistics platforms, and marketing tools via robust APIs.

05 — AUTOMATION

Process Automation

Eliminate manual bottlenecks with intelligent automation — order management, inventory sync, fulfilment workflows, and reporting pipelines.

06 — CONSULTING

Technical Consulting

Architecture reviews, technology selection, and hands-on guidance to help your team ship faster and make the right engineering decisions.
