Your Shopify store has problems. I fix them permanently.

Custom Shopify development, apps built for web and mobile, wholesale setups that don’t require Plus, and deep technical problem-solving for brands that have outgrown quick fixes. I find the root cause, not the band-aid.

Tell Me What's Broken See Problems I Solve

Sound familiar?

Your apps are fighting each other and nobody can figure out why your site is slow.

You're paying $2,000+/mo for Shopify Plus just for basic B2B features.

Your mobile conversion rate tanked and you don't know when or why.

The last developer "fixed" something and now three other things are broken.

Your theme migration went sideways. You lost customizations you spent months building.

Google is penalizing your store for schema conflicts you didn't even know existed.

What We Solve

Technical challenges that keep merchants up at night

These aren't hypotheticals. These are real problems I've diagnosed and resolved for real brands with real revenue on the line.

App Conflict Resolution

Your apps installed fine individually. Together, they're a disaster.

Conflicting scripts, load-order fights, broken checkout flows. I isolate which apps are arguing, trace it to the actual source, and resolve it without disabling tools your business depends on.

B2B Wholesale Infrastructure

Shopify Plus costs $2,000+/mo. You don't need it.

Gated storefronts, net payment terms, tiered pricing, company account workflows. I build wholesale infrastructure with the terms, controls, and buying flow you need on standard Shopify so you keep the margin.

Performance & Mobile Optimization

Every second of load time costs you 7% in conversions.

Core Web Vitals diagnostics, script audits, render-blocking elimination, mobile-specific conversion debugging. I find what is actually hurting your numbers, not what looks suspicious.

Security & Checkout Protection

There might be an exploit in your checkout flow right now.

Checkout vulnerability audits, script injection risks, third-party exposure. I review the full trust chain in your store and close the gaps before they become incidents.

Theme Migration & Upgrades

Updating your theme shouldn't mean losing 6 months of work.

Methodical theme migrations that map every customization before a single line moves. Zero lost functionality. I document what exists, what transfers, and what needs rebuilding.

Analytics & Tracking Architecture

Your conversion data is wrong, and you're making decisions based on it.

Tracking audits, schema conflict resolution, custom event architecture. I rebuild your data layer so your reports reflect what is actually happening in the store.

How I Work

Diagnose Before Prescribing

I spend the first part of every engagement understanding the actual problem, not the assumed problem. Most technical issues have a different root cause than the symptom suggests.

Document Everything

You get a clear record of what was found, what was done, and why. No mystery work. No black-box fixes that break six months later when you touch the wrong file.

Ship in Days, Not Weeks

Most problems I work on are resolved within a day or two of diagnosis. Scoped engagements move fast because I've already solved most of these before.

Automation & AI Enablement

The tedious parts of your business, running themselves

For merchants, service businesses, and teams with repetitive handoffs, I design automation that connects your tools, captures the rules, and brings AI into the parts of the business where it actually helps.

The work starts by mapping how your business actually runs: the call that needs follow-up, the form that becomes a job, the spreadsheet someone updates by hand, the approval that waits in an inbox, the report rebuilt every Monday.

What comes in New orders, emails, phone calls, form submissions What happens Your rules applied automatically — a person looped in when it matters What goes out Tasks assigned, replies sent, records updated, reports ready

Map the real workflow

I trace the handoffs between people, software, messages, calls, spreadsheets, and the judgment calls that keep the business moving. The goal is to find repeated work that is expensive because it lives in memory.

Build the automation layer

Custom scripts, serverless Lambdas, workflow tools, app integrations, API glue, and AI services are selected only when they fit the job. The system is designed around triggers, decisions, actions, and a clear audit trail.

Keep humans in control

Approvals, alerts, fallback paths, and exception queues stay visible. Automation handles the repeated work, then pulls a person in when the decision needs context, risk tolerance, or customer judgment.

Live operating model

Busywork flows in. One automation sends it back done.

Work that used to eat someone's afternoon runs in seconds, logged as it happens — and a person steps in only where judgment matters.

Intake & routingTurn forms, inbound calls, emails, and messages into structured follow-up with the right owner, context, and next step.
Operations adminMove approvals, scheduling, record updates, reporting, and back-office checks out of fragile manual routines.
AI-assisted servicesAdd phone answering, triage, summaries, drafting, lookup, and response support where AI can reduce drag without losing human judgment.
System glueConnect apps, APIs, serverless functions, data stores, and notifications into one documented flow that can be monitored and improved.

About

The person behind the code

I started in software through quality assurance, which means I learned the hard way that the difference between working software and reliable software is almost entirely about what you check before you ship. That background shapes how I approach every engagement.

I spent years breaking things deliberately before I started building them. That changes what you notice in a codebase.

I work with Shopify merchants who have real complexity: multiple storefronts, wholesale operations, deep integrations, and performance requirements that generic developers can't meet. And when the right tool doesn't exist, I build it — Shopify apps, iPhone and Mac apps, web platforms — designed, shipped, and maintained with the same rigor.

I use automation and AI in my own practice the same way I recommend them to clients: to remove repetitive work, sharpen diagnostics, document decisions clearly, and leave more attention for the judgment calls that protect the business.
