Website Development
Business websites, portfolio sites, landing pages, and content-driven builds that are fast, readable, and designed to communicate clearly.
Services
Websites, full-stack builds, analysis, and technical communication.
John McDuffie builds practical digital products and clear supporting materials for teams that need both implementation and explanation.
Services include marketing and content websites, full-stack applications, data analysis, custom software, and technical writing for public-facing or internal use.
Best Fit
Organizations and founders who need a site, application, or reporting workflow delivered with clear documentation and strong communication.
Engagement Types
New builds, redesigns, analytical reporting, internal tools, documentation, and scoped technical consulting.
Working Style
Structured delivery, readable outputs, and systems-minded execution from planning through launch.
Service areas
The work spans both delivery and communication, which helps projects move from idea to shipped product without losing clarity along the way.
Full-Stack Builds
End-to-end web applications with front-end interfaces, backend logic, data flows, and production-minded structure.
Data Analysis
Analytical workflows, reporting, and narrative summaries that turn raw data into patterns, decisions, and usable insight.
Custom Software
Purpose-built tools for internal workflows, automation, process support, and niche operational needs that off-the-shelf software does not cover well.
Technical Writing
Documentation, explainers, implementation notes, and public-facing technical content that help teams and users understand what was built and how it works.
What clients can expect
The goal is not just shipping code. The work is organized so stakeholders can follow the process, understand the output, and keep using it after handoff.
Clear Scope and Structure
Projects are broken into understandable phases so priorities, deliverables, and implementation decisions stay visible.
Readable Deliverables
Whether the output is a site, application, report, or document, it is built to be usable by real people rather than only technical teams.
Technical Depth with Communication
Implementation and explanation are treated as part of the same job, which helps reduce friction during review, launch, and maintenance.
