How I Work
Every engagement starts with understanding the system — not jumping straight to code.
-
Discovery
Requirements mapping, technical audit, and stakeholder alignment. I define scope and surface risk before writing a line of code.
-
Architecture
Stack selection, integration design, and delivery planning. The blueprint that prevents surprises — and keeps projects on budget.
-
Build
Custom development, third-party integrations, and QA coordination. Clean, maintainable code with clear progress communication throughout.
-
Launch
Go-live execution, performance validation, and post-launch support. Handed over properly — not just deployed and abandoned.
Selected Work
Projects across fashion, beauty, lifestyle, wine, and B2B verticals. Client details available on request under NDA.
About
I'm Ailene Pecayo, a Developer and Solution Architect with 18+ years of experience building scalable digital commerce solutions.
With 9+ years specialising in Shopify and Shopify Plus, I've delivered projects across fashion, furniture, beauty, health, B2B, subscription, and retail — for both growing brands and established Shopify Plus merchants worldwide.
Beyond development, I regularly lead technical discovery, architecture planning, project estimation, code reviews, and client-facing discussions to ensure every project is delivered efficiently and aligned with business goals.
I work with brands directly as well as alongside agencies and development teams as a senior technical resource.
I stay current with emerging tools and technology to deliver faster without cutting corners.
Let's work
together.
