A ~50% efficiency gain (client-reported) on a working Shopify business with more than ten storefronts, without a rewrite. On-chain loyalty primitives added to a live marketplace without the user ever seeing crypto. A drop checkout benchmarked at 1,000+ concurrent users with real money flowing through it, and a multi-chain Point-of-Sale checkout for shops, restaurants, and hotels. E-commerce work is judged in operations and conversion, and that is where we aim. 4 case studies 3 questions answered 3 related services Shipped work > “The most dangerous sentence in e-commerce engineering is 'let's replatform'. Most shops need the right ten moves on the stack they already run.” TL;DR A ~50% efficiency gain (client-reported) on a working Shopify business without a rewrite, on-chain features added to a live marketplace without the user ever seeing crypto, a drop checkout benchmarked at 1,000+ concurrent users, and a multi-chain Point-of-Sale checkout. // 01 ## What we build in this industry [MyMerch](/case-studies/mymerch/) is a German merchandise and print-on-demand brand selling through more than ten Shopify storefronts. No rewrite, no replatforming theatre. We made the right moves on the existing stack: fulfilment and process automation that reduced delivery errors, storefront work that lifted conversion. The client reports a roughly 50% efficiency gain across the operation. [Afoma](/case-studies/afoma/) is a live marketplace that wanted [Web3](/glossary/web3/) features without alienating users who do not know what a wallet is. Social login, invisible wallet creation, on-chain primitives under a normal shopping experience. Two more commerce builds round it out. [LivLive](/case-studies/livlive/) runs drop-based selling, so we built and benchmarked its checkout at 1,000+ concurrent users with zero degradation, with real money flowing through it. [ScramblePay](/case-studies/scramble-pay/) is a multi-chain Point-of-Sale and web checkout that drops into online shops and handles on-site payments in restaurants, hotels, and bars. The common thread: e-commerce businesses run on thin margins and live operations. The [software engineering](/services/software-development/) that matters is the kind that shows up in error rates, fulfilment speed, and checkout conversion, not in a tech-stack announcement. Most of it lives in the [web app](/services/web-apps/) layer customers actually touch. ### Operations & storefront optimization The MyMerch shape: automate fulfilment, kill recurring errors, lift storefront conversion, on the platform you already run. Measured against your numbers, not ours. ### Custom commerce features Loyalty systems, marketplace mechanics, payment flows beyond what plugins do, including on-chain features your customers never have to understand. ### Spike-proof commerce builds Drop-based and campaign-driven selling concentrates a month of traffic into an hour. We have benchmarked a custom checkout at 1,000+ concurrent users with zero degradation. // 02 ## What makes this industry hard ### Plugin stacks hit a ceiling Shopify and friends get you far, then every new requirement becomes three conflicting apps and a manual workaround. The fix is usually surgical custom code, not a replatform. ### Fulfilment errors compound quietly A 2% error rate is invisible in a dashboard and very visible in your support inbox and margins. Process automation is the least glamorous, highest-ROI engineering in commerce. ### Traffic is spiky by design Marketing creates the spike, engineering has to absorb it. Checkouts that flatten under drop-day load turn your best marketing into your worst week. // 03 ## Shipped work in this industry Four shipped engagements: a deep operations win on Shopify, a live marketplace with invisible Web3, a spike-proof drop checkout, and a multi-chain Point-of-Sale checkout. ### [MyMerch](/case-studies/mymerch/) - **Status:** Live - **Outcome:** ~50% - Efficiency Gain (Client-Reported) - **Summary:** ~50% efficiency gain (client-reported).

Not as a theme shop. We do engineering on and around commerce platforms: process automation, custom features, integrations, performance. If you need a templated store launched, a Shopify agency is cheaper and faster for that job. ### Will you tell us to replatform? Probably not. MyMerch got a roughly 50% efficiency gain with zero replatforming. We recommend a migration only when the current platform is the measured bottleneck, which is rarer than agencies pretend. ### Can you add AI to our shop? Where it earns its keep, yes: product data automation, support deflection, search. We will not bolt on a chatbot just so the deck says AI.
