Mikhail E.

CS-Cart Certified Developer and Laravel Developer, former X-Cart HQ engineer. I build custom CS-Cart modules and architect Laravel apps — including REST API integrations, ERP/CRM synchronization, legacy code rescue, and multi-tenant SaaS foundations. I also develop Laravel + Vue.js + Inertia.js frontends for full-stack delivery. I spent 6 years inside X-Cart's core teams — 4 years in Client Customization and 2 years in the Upgrade Department, where I personally completed around 40% of all official company upgrades. That hands-on experience with production e-commerce systems is what I now bring to CS-Cart modules and Laravel applications. With a proven track record of building, scaling, and securing production-grade applications, I help national brands and e-commerce leaders grow. Today, I combine that production e-commerce experience with a modern full-stack ecosystem to deliver high-performing CS-Cart solutions, bespoke Laravel enterprise software, and X-Cart development: 🏆 CS-Cart & Multi-Vendor Expertise • Custom Add-on Development: Engineering bespoke admin tools, advanced dashboards, advanced shipping rules, custom payment gateway integrations (including CyberSource, Afterpay, and various global providers), and automated KYC workflows using the CS-Cart Hooks system and TPL/Smarty templates. • REST API & Integrations: Developing custom CS-Cart REST API endpoints for flawless synchronization with external ERPs, CRMs, marketplaces, accounting software, and fulfillment services. • Seamless Upgrades & Migrations: Risk-free updates from older legacy versions (e.g., CS-Cart 4.x) to the latest releases with 100% data integrity, theme refactoring, and database optimization across CS-Cart Ultimate & Multi-Vendor platforms. • Advanced Marketplaces: High-load marketplace setups, custom vendor commission models, automated vendor onboarding, separate vendor panels, and custom checkout flows. 🔥 Laravel Framework & Enterprise Architecture • Custom Web Apps & SaaS: Building scalable multi-tenant platforms, subscription-based services, and complex custom management systems from scratch using clean Laravel architecture (SOLID, DDD). • Modern SPAs (Vue.js & Inertia.js): Creating fast, reactive user interfaces with Vue 3 and Inertia.js for a seamless, app-like user experience without complex API overhead. • Tailored Headless E-commerce: Engineering custom headless e-commerce platforms, advanced marketplace tech, high-performance booking systems, and automated billing/invoice software. • REST & GraphQL API Integrations: Designing robust APIs and achieving flawless synchronization with external ERP, CRM, and third-party fulfillment services. • LLM integrations for product content generation and customer-facing chatbots 🚀 X-Cart Platform Development • Custom Module Development: Building tailored modules, advanced business logic, checkout refactoring, and admin tools based on X-Cart module architecture. • X-Cart API & Third-Party Connections: Implementing X-Cart API integrations, webhooks, and secure connections with payment gateways, BNPL services, custom shipping providers, and inventory management systems. • Legacy Upgrades & Data Integrity: Risk-free data migration and platform updates from older versions (X-Cart 4 Classic / X-Cart 5) to the latest stable releases with zero downtime and full core compatibility. • Performance & Core Tuning: Speed optimization, database optimization (MySQL/MariaDB), and troubleshooting complex code or module conflicts. ⚙️ Tech Stack & Tools: • E-commerce Platforms: CS-Cart, CS-Cart Multi-Vendor, CS-Cart Ultimate, X-Cart (Classic & Next-Gen). • Backend Frameworks & Languages: PHP (OOP, SOLID, DDD, Clean Architecture), Laravel Framework (Blade, Livewire, Filament, Sanctum/Passport, Eloquent ORM, REST/GraphQL APIs, Queues/Redis), MySQL / PostgreSQL. • Frontend & UI Stack: Vue 3 (Composition API), TypeScript, Inertia.js, JavaScript (Async/AJAX), Tailwind CSS, Smarty & Twig (CMS templates), HTML5 / CSS3. • AI & Integrations: OpenAI API, Claude API (LLM integrations for content generation, chatbots, and product descriptions). • Payment & BNPL Integrations: CyberSource, Afterpay, Stripe, PayPal, and various custom payment gateway integrations (PSP, local & global APIs). • Development & Deployment: Docker, Composer, Vite, NPM, Git / GitHub, CI/CD. By combining modern architecture with deep industry insights, I turn complex requirements into stable, high-converting platforms. 📩 Ready to upgrade your store or build a custom application?
