Senior Shopify expert with 8+ years building and scaling stores for ecommerce brands, now delivering it all AI-native: faster, sharper, and more output for your budget, without losing quality or control. KEY PROOF ✅ Expert-Vetted by Upwork (top freelancers on the platform) ✅ 100% Job Success · $200k+ earned across 90+ projects · 2,700+hours ✅ 112M+ in ecommerce revenue influenced across Shopify and Shopify Plus brands ✅ 8+ years as a hands-on Shopify developer, CRO operator, and technical partner ✅ Builder of Axel, an AI delivery platform purpose-built for Shopify execution WHAT I DO Custom Shopify and Shopify Plus builds, theme development, and redesigns Conversion rate optimization: landing pages, PDPs, funnels, A/B tests Custom Shopify apps and integrations (replace expensive apps with owned solutions) Migrations, replatforming, and technical fixes Ongoing development and support that ships fast THE AI-NATIVE DIFFERENCE Most Shopify work is still billed by the hour and moves at agency speed. I deliver the same work AI-native, using an AI delivery engine (Axel) with human oversight at every step. That means compressed timelines, more done for the same budget, and the quality control you would expect from a senior developer. Not AI theatre, not fragile automations. Real, reviewed, production work, just faster. WHO THIS IS FOR Established Shopify and Shopify Plus brands that need to move faster without hiring a bigger team Brands with a backlog of builds, tests, fixes, or custom features Teams tired of slow agency queues and inflated hours HOW I WORK I work as a senior technical partner, not a task-taker. We scope the outcome, I deliver it AI-native with full visibility, you review and approve. For larger or ongoing work, I bring delivery capacity through my team at Your Digital Media. WHAT CLIENTS SAY “Professional, timely, and beyond expectations. We have been working with Alex and Your Digital Media for several months now. Our initial collaboration kicked off with the complete build from scratch of a new Shopify theme for our business. This project was delivered exactly as per our expectations.” — Cristian Faragau, Marketing Manager at Gleefull Supplements “You are in good hands with YDM. They have helped us improve all aspects of our site. They are professional, timely and always willing to help. Nothing is a silly question and I love knowing that I can call on them for strategy as well as emergencies.” — Amelia Hicks If you want a Shopify expert who ships faster because the delivery is AI-native, send a message with your store, the work you need, and your timeline.

Focused entirely on designing crypto and equities trading algorithms — building signal generation models in Python, backtesting against historical tick data, and training on Nvidia hardware for low-latency inference. I was trained classically, writing C and C++ code for Wall Street trading powerhouses like Goldman Sachs and Lehman Brothers. Running on advanced Unix systems, these lightning fast applications pioneered the field of today's realtime global FinTech. That low-level performance discipline is exactly what I bring to Python today: when a pandas pipeline or a pricing model needs to run faster, I know how to profile it, rewrite the hot path in C/C++, and bind it back in — rather than just accepting whatever speed the interpreter gives me. As the Internet spawned open source platforms like Linux, MySQL, NodeJS, and AWS Cloud API's, my skillset evolved into a full-stack portfolio: Python and C++ on the backend for quant logic and performance-critical services, NodeJS gluing together APIs and real-time data feeds, and JavaScript up front to deliver large, complex datasets through clean, intuitive web portals. That range — comfortable in Python's data/ML ecosystem, NodeJS's async API layer, and raw C/C++ when milliseconds matter — is what lets me own a fintech product end to end instead of handing it off between specialists. After moving to the West Coast in 2016, and spending time in Silicon Valley, I ventured into Blockchain protocol coding, video streaming/FFmpeg, and network traffic optimization down to the TCP/IP stack — all of it reinforcing the same core skill: designing and coding custom algorithms. Whether it's a Python model scoring trading signals in real time, a Node service exposing that model over a REST API, or a C++ routine doing the number-crunching underneath, the ability to move fluidly across that stack is what separates a production-ready fintech system from one that never leaves the GitHub repo. From my early career, I have made database structure the centerpiece of my application design. Classical training in Dr. E. F. Codd's model of Relational Databases has always informed my philosophy of how to structure an application's data repository. With web-scale data, this field has grown to NoSQL and Graph databases, and now huge datasets underpin the training of AI/ML models.
