How I
work.

Every project follows a clear, proven workflow. No surprises, no scope creep — just steady progress from idea to launch.

01

Discovery & Strategy

We start with a conversation. I learn your goals, audience, and technical requirements. Then I map out the architecture, choose the right stack, and define a clear project scope.

02

Design & Prototype

Wireframes and mockups before any code is written. You see exactly what you're getting. Responsive layouts, interaction patterns, and visual direction — all approved before build begins.

03

Build & Test

Clean, hand-written code. Every feature is tested across devices and browsers. Performance is optimized, accessibility is checked, and SEO is baked in from the start.

04

Launch & Support

Deployment, hosting setup, DNS config, and go-live. After launch, I provide ongoing maintenance, security updates, and performance monitoring to keep your project running at peak.

Design eye,
developer hands.

I was trained in traditional graphic design and photography — composition, color theory, typography, and the kind of visual instinct that makes designs catch the eye. That foundation shapes everything I build.

I've been building for the web since the days of 56k modems and table-based layouts. What started as a fascination with how the internet worked became a freelance career spanning decades — from early HTML to full-stack development across web and mobile.

Today I build full custom HTML websites, web applications, and native apps for both Apple (Swift) and Android (Kotlin). I handle everything from design and SEO strategy to hosting, deployment, and long-term maintenance. My app QuantumShelf is a testament to that full-stack approach — designed, built, and shipped entirely by me.

How every project
is built.

Foundation

Custom Code

No templates, no page builders. Every site is hand-written HTML, CSS, and JavaScript — built for speed and SEO from day one.

Performance

SEO & Speed

Semantic markup, meta optimization, structured data, and sub-second load times. Your site is built to rank and convert.

Reliability

Hosting & Support

Managed hosting, SSL, backups, uptime monitoring, and ongoing maintenance are available as add-ons — so you have options for long-term support after launch.
