Why Work Directly With A Senior Developer

Traditional agencies add layers of account managers, sales commissions, and junior developers. Here is why clients work directly with me.

Working With Me

Direct, Accountable Senior Engineering

  • Direct Communication: You speak directly with the senior developer writing the code.
  • Clean, Bloat-Free Code: Engineered for sub-second speeds and long-term maintainability.
  • Fair, Transparent Rates: You only pay for engineering hours—no agency overhead or middleman fees.
  • Full Code Ownership: Pushed straight to your GitHub, Shopify theme, or server.
  • Fast Turnarounds: Quick iteration cycles and immediate Slack/WhatsApp responsiveness.
Traditional Agency

High Overhead & Layers of Communication

  • Account Manager Delays: Feedback passes through 2–3 non-technical staff before reaching coders.
  • Junior Execution: Pitched by seniors, but your actual project is often handed to junior hires.
  • 2x to 3x Agency Markup: Paying for fancy offices, account managers, and sales teams.
  • Proprietary Lock-in: Often hard to manage without paying recurring agency retainers.
  • Slow Changes: Even small text or section updates can take weeks to get scheduled.
Frequently Asked Questions

Shopify Development FAQs

Common questions clients ask before starting a project.

Can you customize my existing Shopify theme or do we need to start from scratch?

I can work with either approach. If you have an existing theme (Dawn, Impulse, Prestige, etc.) that needs custom Liquid sections, bug fixes, or speed optimization, I can build directly on top of it. If you need a fully custom build, I can develop it from Figma designs.

Will I be able to edit text and images myself after the project is done?

Yes, 100%. All custom sections are built using Shopify OS 2.0 theme architecture with intuitive schema settings. You can edit text, imagery, colors, and layout directly inside the Shopify visual theme editor.

How do you handle subscriptions and complex shipping rules?

I have deep experience integrating subscription engines like Recharge, Bold, and native Shopify Subscriptions, as well as complex shipping rules, delivery date pickers, and perishable goods handling.

Do you provide ongoing monthly support for Shopify stores?

Yes. I offer dedicated monthly retainers for ongoing store updates, new feature builds, A/B testing implementation, and emergency technical support.
