Sidney Rees, Fractional CTO and PMO for eCommerce

Sidney Rees: Fractional CTO + PMO for eCommerce

I fix the technology side of eCommerce companies when growth stalls, vendors don't deliver, or the platform can't scale. CTO-level decisions and PMO-level execution, same person. WooCommerce expert.

Proof: recovered 40,000+ products and 8,000+ customer records from vendor lock-in in 7 days, zero downtime.

Book a free 30-min eCommerce tech diagnostic → You leave with the 3 biggest risks in your stack and vendor setup, and what I'd fix first.

When to call me

  • Your roadmap slipped and nobody can give you a real ship date
  • An agency or vendor controls your data, code, or access, and isn't delivering
  • Your WooCommerce store slows down or breaks as catalog, traffic, or integrations grow
  • Operations run on manual work: stock sync, order routing, spreadsheets between systems
  • A migration, recovery, or vendor transition has become business-critical

Results

40,000+ products recovered. 8,000+ customers migrated. 7 days. Zero downtime. A vendor held the store's data hostage. I built Python recovery bots, stood up new WooCommerce infrastructure, and ran extraction and migration in parallel. Read the case study →

Sales doubled from week one. Manual workload down 50%. Connected Mercado Libre with WooCommerce, automated stock sync, and redesigned the fulfillment workflow. Read the case study →

All documented cases →

How we work

  1. Free diagnostic (30 min): risks, quick wins, what to fix first
  2. Fixed-scope project: migration, recovery, integration, or vendor turnaround, with a defined deliverable
  3. Fractional retainer: ongoing CTO + PMO ownership of roadmap, vendors, delivery, and QA

Satisfaction guaranteed.
