Led a massive technical turnaround and re-architecture for a major industrial steel supplier. I inherited a deeply flawed legacy WordPress infrastructure where a misguided rebranding attempt (to "Steelsara") by the previous developer had caused catastrophic SEO de-indexing, fatal Google Search Console errors, and unmanageable 40-second page load times. I successfully rescued the legacy site, dropping load times to under 2 seconds and restoring its search presence. Simultaneously, to future-proof the business and reclaim the company’s original market identity, I architected, engineered, and deployed a completely new, high-performance custom web platform from scratch under the flagship brand, "Steel mohafa". Key Engineering Contributions & Achievements: Crisis Management & Technical SEO Recovery: Diagnosed and resolved critical performance bottlenecks on the legacy WordPress site, reducing initial load times from a disastrous 40+ seconds to under 2 seconds. Identified and purged persistent rogue noindex tags and conflicting plugins that had caused the site to drop out of Google's index. Implemented precise JSON-LD structured data (Product, FAQ, LocalBusiness) to recover and eventually dominate competitive SEO rankings for industrial steel keywords. Re-Architecture & Custom Platform Development (Steel mohafa): Decoupled from the limitations of WordPress by engineering a modern, headless-style architecture using Vue.js and Nuxt 3 (Nitro engine) for exceptional SSR (Server-Side Rendering) performance. Designed a highly optimized frontend utilizing Tailwind CSS, featuring a custom corporate identity (incorporating brand-specific Ruby-red themes, Advanced, rugged style (tailored to the iron market), and an industrial 'Bento Grid' layout) tailored specifically for B2B clients. Engineered a fully functional Progressive Web App (PWA) with custom service workers (sw.js), intelligent lazy loading (20 items/batch), caching strategies, and interactive installation guides for mobile users. Advanced Database & Pricing Engine Architecture: Architected a highly normalized MySQL 8 database utilizing Prisma ORM to manage a massive catalog of ~11,000 heavy industrial products. Engineered a complex, rule-based dynamic pricing engine. Instead of static prices, I developed an algorithm that calculates real-time costs based on precise engineering formulas (weight calculation for sheets, round bars, pipes, and profiles), dynamic alloy multipliers (e.g., 304, 316, 430 grades), surface types, and daily market adjustments. Designed decoupled database triggers (after_category_price_update) to automate site-wide pricing syncs instantly, eliminating the need for manual data entry and preventing calculation errors. Frontend Interactivity & Performance: Developed highly interactive client-side tools, including an instant weight-to-price calculator with real-time DOM updates, success/error states, and a dynamic VAT toggle utilizing localStorage. Resolved complex TypeScript build errors and strict prop validations, ensuring a highly robust, enterprise-grade codebase. Tech Stack: Vue.js, Nuxt 3 (Nitro), Tailwind CSS, TypeScript, Node.js, Prisma ORM, MySQL 8, PWA (Service Workers), Advanced Technical SEO, WordPress (Legacy Rescue).

Spearheaded the complete digital transformation and technical architecture for a leading B2B/B2C industrial tools retailer. Operating as the sole technical lead, I architected, engineered, and deployed a highly scalable digital ecosystem consisting of multiple web platforms and a native Android application ("Stock"). I owned the entire software development lifecycle, from database design and cloud infrastructure to UI/UX implementation and AI integration, successfully transitioning the company from traditional sales to a robust digital marketplace. Key Engineering Contributions & Achievements: Systems Architecture & Backend Engineering: Designed and engineered a resilient, API-driven backend architecture using Python and Flask, processing complex inventory logistics, user authentication, and multi-vendor product listings. Architected a highly normalized relational database schema capable of managing thousands of heavy machinery SKUs, specific spare parts, and dynamic price fluctuations without performance degradation. Engineered automated data pipelines and synchronization mechanisms across multiple domains to ensure real-time inventory consistency. Mobile App & Frontend Development: Developed and successfully published the "Stock" Android application on major regional app stores (Cafe Bazaar, Myket). Engineered a high-performance Kotlin-based WebView bridge, ensuring seamless, native-like communication between the Android hardware and the web server, optimizing memory footprints and reducing load times. Implemented advanced front-end UI/UX architectures using HTML/CSS and modern JavaScript. Authored custom CSS layers (e.g., iOS-style glassmorphism with backdrop filters and optimized rendering) overriding default themes to deliver a premium, high-conversion user experience. AI Integration & Search Optimization: Designed and deployed an intelligent, NLP-driven product search architecture (intelligent_product_search) embedded within the marketplace. Transitioned the search logic from a heavy two-stage architecture to a highly optimized single-shot querying system, significantly reducing server load and API latency. Enabled complex multi-column database filtering (by brand, equipment type, and dynamic price ranges) allowing users to find highly specific industrial components through natural language queries. DevOps, Security & Infrastructure: Managed end-to-end server deployments, configuring Linux environments and maintaining high availability. Administered domain parking, DNS management, and SSL provisioning via Cloudflare, implementing robust caching rules and DDoS protection layers to secure the platforms against malicious traffic. Technical SEO & E-Commerce Strategy: Implemented a highly technical "Topic Cluster" SEO architecture for thousands of complex spare parts, systematically eliminating keyword cannibalization and duplicate content issues. Configured headless-style API integrations with WooCommerce, ensuring extremely fast page delivery for B2B clients and optimizing the platform for technical search engine crawling. Tech Stack: Python, Flask, Kotlin (Android), JavaScript, Vue.js concepts, MySQL/SQLite, HTML5/CSS3 (Custom UI), Cloudflare, RESTful APIs, AI Search Logic.
