Mobile Design Development Online

Mobile Revenue Protection

Every 100ms of LCP improvement drives measurable checkout lift. I audit and eliminate the client-side bloat silently killing your mobile funnel — before it shows up as a miss.

Analytics data integrity

Analytics You Can Trust

Klaviyo drops, GA4 gaps, and mismatched attribution mean your team is optimizing against fiction. I ensure 0% event packet loss between your storefront and your data warehouse.

Tech debt elimination

Tech Debt That Pays Off

App and plugin creep costs brands 8–12 Lighthouse points and seconds of load time per install. I cut the dead weight, show the P&L impact, and keep your stack lean.

Bump Boxes

The Business Bottleneck

A fast-growing pregnancy subscription brand on WordPress with checkout conversion degrading as SKU count scaled. Mobile load times exceeded 6 seconds; the engineering team had no path to ship features without risking the monolith.

The Technical Choice

Led migration from WordPress to a custom React + GraphQL application, decoupling the storefront from the backend and enabling independent frontend deployments. Rebuilt the checkout experience from the ground up with performance as the primary KPI.

The Financial Impact

50% reduction in mobile load times. 40% increase in checkout conversion rates. Subscription architecture now scales gracefully to 10x SKU volume without performance regression.

Grainger

The Business Bottleneck

A Fortune 500 industrial distributor with a sprawling eCommerce presence that had grown desktop-only — mobile users were abandoning key product and homepage flows at high rates.

The Technical Choice

Joined a cross-functional team of 6+ engineers and project managers to rebuild core pages (homepage, product pages) from the ground up with a responsive, mobile-first architecture.

The Financial Impact

Enterprise-grade responsiveness shipped at scale across one of the largest B2B eCommerce properties in the US, with measurable improvements to mobile usability across millions of monthly sessions.

Natural Music

The Business Bottleneck

A music instruction business with a loyal in-person customer base but no scalable way to reach learners online. Revenue was capped by physical location and instructor availability.

The Technical Choice

Designed and built a subscription-based online lessons platform. Architected the monthly sign-up flow to funnel visitors toward a single conversion action, eliminating friction at every step.

The Financial Impact

Transformed a location-dependent business into a recurring-revenue subscription model, unlocking national reach and predictable monthly income.

Pen & Paper Trivia

The Business Bottleneck

A fast-growing bar trivia company was adding hosts and venues faster than its online presence could keep up. Without a professional website, Paul was walking into venue pitches with nothing to back his credibility — losing deals to first impressions before the conversation even started.

The Technical Choice

Built a custom WordPress theme from scratch incorporating the brand's colors and logo. Designed a custom event management system inside the CMS to handle the full complexity of the operation: weekly recurring events, bi-weekly events, and one-off or irregularly scheduled shows — all manageable by non-technical staff without developer involvement.

The Financial Impact

Venue count grew from 7 at launch to 18 — a 157% increase. The site sustains an 80.77% engagement rate and a 41% click-through rate from search, signaling that prospective venues who find it are actually converting on contact. Staff manage the full event schedule independently with zero developer involvement.

Rambler

Rambler

Rambler is a brick-and-mortar retail store that opened its doors in 2016. After a couple of years in business, Drew reached out to start thinking of trying to start the online version of the Rambler store as well.

We worked with their Point-of-Sale to make sure their online store synced inventory to their site seamlessly — so people purchasing online and in-store wouldn't have any issues with out-of-stock items.
