I don't just build WordPress sites; I architect high-performance digital ecosystems.

I specialize in bridging the gap between complex PHP/MySQL backends and interactive React frontends. My focus isn't just on writing code it's on Business Logic, Scalability, and ROI.

• ⚡ Performance Obsessed: I recently re-architected an LMS plugin to reduce server load by 40% during high-concurrency spikes.
• **⚡ Created a professional-grade multi-step measurement Plugin Sartorly for WooCommerce that allows tailoring businesses to capture complex anatomical data using a logic-driven user interface.
• **⚡Developed a dynamic gamification widget named "Grow Monster Addons" by integrating React.js widgets within the Elementor ecosystem for real-time user engagement.
• 🇪🇺 EU Market Ready: Experienced in building GDPR-compliant platforms with complex EU VAT/Tax logic (see Nasomed below).
• 👥 Team Lead & Mentor: I don't just code; I elevate teams. I have experience conducting code reviews and mentoring junior developers on hook implementation and clean architecture.
• 🤝 B2B/Contract Friendly: Based in Bangladesh (GMT+6) but available as an Independent Contractor. I offer 4+ hours of overlap with European/US business hours for meetings, using the rest of the day for deep work.

Because much of my work is under strict NDA/Client constraints, I cannot share the raw code. Here is the engineering behind my top projects:

The Challenge: A complex multi-currency retail ecosystem requiring strict adherence to EU Regulations and VAT logic. The Solution: Deployed a specialized WooCommerce checkout flow handling intricate tax rules and secure payment gateways specific to the European market. The Result: 99.9% uptime for medical professionals and full regulatory compliance.

The Challenge: Existing market solutions (Tutor LMS/LearnDash) were causing database bottlenecks for a client with thousands of concurrent students. The Solution: Architected a custom LMS plugin from scratch. Optimized SQL queries and database schema. The Result: 40% reduction in server load and faster course rendering times.

The Challenge: The client needed real-time user engagement without page reloads, inside a standard Elementor page builder environment. The Solution: Built a custom addon integrating React.js widgets directly into Elementor, communicating via custom REST API endpoints. The Result: A dynamic, app-like experience within a WordPress environment.

• Created a professional-grade multi-step measurement wizard for WooCommerce that allows tailoring businesses to capture complex anatomical data using a logic-driven user interface. • A dynamic pricing engine that calculates real-time costs based on garment components (top, bottom, and full-set), using WooCommerce CRUD and native metadata APIs for seamless checkout integration. • Optimized the data architecture to support "Saved Measurement Profiles," which allow logged-in users to re-order custom apparel with no data entry, significantly increasing customer retention and conversion rates. • Ensured 100% compliance with WordPress.org security standards by implementing strong sanitization, escaping, and nonce verification while keeping a small footprint and no external dependencies.

• Architected a high-performance LMS plugin from scratch, optimizing custom SQL queries to reduce server load by 40% during concurrent user spikes. • Developed a lightweight database schema superior to market leaders, delivering faster course rendering and scalable student tracking features compare to Tutor LMS, Academy LMS Learn dash etc. (Project Still Continuing)

• Developed a dynamic gamification engine by integrating React.js widgets within the Elementor ecosystem for real-time user engagement. • Implemented custom API endpoints to handle complex logic without page reloads, bridging the gap between static design and interactive web application features.

URL: https://github.com/Sourav2008/TecAi-Ally-Wordpress • Workign on TecSupport Genius, an AI-powered chatbot with ticketing engine for WordPress. • Integrated Google Gemini/GPT-4 for RAG-based site training and developed "Ghost Mode" for real-time typing previews. Built a native "Jira-Lite" ticketing system and WooCommerce order-tracking agents.

Why am I different from other developers? Before focusing 100% on Architecture, I worked as a Technical Recruiter for Fortune 500 clients.

• I understand the SDLC from a business perspective.
• I write code that is clean, documented, and easy for your future team to inherit.
• I communicate proactively—no ghosting, just results.

I am actively looking for Remote Roles (Contract/B2B) with European or US-based tech teams.
