Question 1

What does Hazem Salama do?

Accepted Answer

Hazem Salama is Head of E-commerce Engineering at Qusah Stores and an engineering leader measured in revenue rather than tickets. He runs a 7-engineer team behind ERP, contract, and e-commerce platforms processing 10,000+ daily transactions, and builds enterprise SaaS, multi-tenant ERP, and marketplace platforms as an independent engineer — 15+ production applications, 50,000+ users, and 12M+ SAR in tracked client revenue.

Question 2

Can you fix a slow e-commerce storefront and improve Core Web Vitals?

Accepted Answer

Yes. On a flagship Salla storefront I raised the mobile Lighthouse score from 36 to 68, cut layout shift (CLS) 93% from 0.85 to 0.06, reduced main-thread blocking (TBT) 85% from 1,170ms to 180ms, and brought LCP from 16s down to 6s — alongside conversion-focused changes across all product pages. I also run cross-source growth analyses (GA4, ad platforms, Microsoft Clarity, lab and field Core Web Vitals) to isolate whether a revenue problem is site performance or channel efficiency.

Question 3

Can you run technical due diligence on a store or platform acquisition?

Accepted Answer

Yes. I led the technical scoping of a competitor storefront acquisition and delivered the full platform migration and visual rebuild in 2 days with zero downtime to live trading, replacing template constraints with an in-house custom Salla theme.

Question 4

How does the software development process work?

Accepted Answer

I follow a structured Agile software development lifecycle: 1) Discovery and requirements gathering, 2) Software architecture and planning, 3) Design phase with UI/UX prototypes, 4) Iterative development with regular sprints, 5) Continuous testing and quality assurance, 6) Deployment and launch, 7) Post-launch support and maintenance. This ensures transparency, flexibility, and quality throughout the software development lifecycle.

Question 5

What software development methodologies do you use?

Accepted Answer

I employ Agile and Scrum methodologies for iterative, collaborative software development. I also practice Lean software development principles to minimize waste and maximize value delivery. This includes regular sprint planning, sprint reviews, and retrospectives to ensure continuous improvement.

Question 6

Can you implement ZATCA Phase 2 e-invoicing?

Accepted Answer

Yes. Mowazana, a multi-tenant SaaS ERP and POS platform I built solo, clears invoices with ZATCA in real time: UBL 2.1 invoice construction, XAdES-BES signing over ECDSA secp256k1, TLV QR codes, B2B clearance and B2C reporting, and a per-tenant invoice hash chain.

My Saudi and Gulf platform work has generated over 12M SAR in measurable client revenue, and I serve UAE businesses with the same Gulf-market expertise.
