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

Custom Plugins & APIs FAQs

Common questions clients ask before starting a project.

Why build a custom plugin instead of using an existing free/paid one?

Most generic plugins come with thousands of lines of unused code, unwanted marketing notices, and recurring annual fees. A custom plugin does exactly what your business requires—faster, more securely, and with zero recurring software licenses.

Will the custom plugin break when WordPress updates?

No. I write custom plugins following standard WordPress API hooks, actions, and filters without modifying WordPress core files. Your plugin will safely survive WordPress core updates.

Can you connect WordPress to our custom software or external database?

Yes. Whether using REST APIs, GraphQL, webhooks, or direct secure database queries with $wpdb, I can engineer reliable bidirectional data pipelines.

Do you provide documentation for the custom plugin?

Yes. All code is cleanly documented with PHP DocBlocks, and I provide a clear developer handoff guide detailing hooks, settings, and API payloads.
