About

Commerce architect.
Not just a consultant.

I'm Naga — a Technical Architect with 25+ years in technology and over 20 of those deep in enterprise ecommerce. My work sits at the intersection of platform engineering, system integration, and business strategy — turning complex commerce requirements into architectures that actually ship.

I now work independently as a Freelance Ecommerce Architect, taking on select consulting engagements with clients across APAC, the Middle East, North America, and Europe — bringing the same rigour of a large agency, without the overhead.

I've built systems on legacy monoliths and cutting-edge composable stacks. I've led migrations, integrations, and greenfield builds. That breadth is what I bring to every engagement.

Let me help you move faster

I take on a limited number of independent consulting engagements — typically with mid-market retailers, brands, and tech teams who need a senior commerce architect without the overhead of a large agency. Fast time-to-value. No fluff.

Platform Migration Advisory

Leaving ATG? Evaluating commercetools vs Kibo vs OCC? I'll give you an honest, technically grounded view — not a vendor pitch.

Architecture Review & Design

Existing system health checks, API design reviews, composable architecture blueprints, and BFF/integration layer design.

Integration Strategy

Third-party integrations — search, OMS, PIM, tax, payments, marketing — designed to be reliable, maintainable, and decoupled.

Technical Due Diligence

Pre-M&A or pre-investment tech stack assessments. I'll give you the real picture of what you're inheriting or acquiring.

Team Enablement

Workshops, code reviews, best-practice documentation, and knowledge transfer for in-house teams working on complex platforms.

Hands-on Delivery

For the right engagement, I roll up my sleeves. Spring Boot backends, commercetools implementations, integration layers — production-ready.
