// 01_bio & story
Backend craftsmanship built on deep fundamentals.
8+ years of commercial software engineering, scaling WordPress & Shopify architectures, crafting high-performance PHP APIs, and building maintainable digital platforms.
Hi, I'm Zahid Uddin - a software engineer passionate about clean code, high-scale CMS architecture, and high-converting e-commerce.
Over the past 8 years, I have built and maintained 35+ commercial websites, bespoke Shopify stores, and enterprise WordPress platforms for clients across the United States, Europe, and Asia. My expertise centers on translating complex business logic into clean, robust object-oriented PHP, custom Full Site Editing (FSE) themes, bespoke Gutenberg blocks with ACF Pro, tailor-made Shopify Liquid sections, and scalable REST APIs.
I reject the bloated "page-builder sprawl" common in traditional web development. Instead, I write modular, zero-dependency code, optimize database indexes, configure Redis object caching, and fine-tune server stacks (PHP-FPM, OPcache, NGINX, Cloudflare) to deliver sub-second page loads and 95+ Core Web Vitals scores across both WordPress and Shopify ecosystems.
// core principles
How I think about software.
Zero Bloat & Maintainability
Code should be readable by humans first. I use clean OOP design patterns, strict type hints, and explicit dependency injection to prevent technical debt.
Sub-Second Performance
Speed is not an afterthought. From SQL query optimization to Redis caching and asset minification, every line of code is engineered for sub-second delivery.
Intuitive CMS Workflows
Content teams shouldn't need a developer to make routine updates. I craft custom Gutenberg blocks with ACF Pro that empower marketing without breaking design systems.
Security & 99.9% Uptime
Defensive coding, input sanitization, nonce verification, rate limiting, and zero-downtime deployment pipelines ensure platforms stay secure and reliable.

Experience & Education.
Senior Software Engineer (Lead)
- Lead backend-focused WordPress development for custom themes, plugins, and scalable content platforms, serving as the primary technical anchor for high-traffic environments.
- Secured top-tier Core Web Vitals and eliminated database bottlenecks by implementing advanced server-level caching hierarchies (Cloudflare, Redis/Object Cache, OPcache, and NGINX).
- Engineered dynamic, decoupled content systems using React-driven Gutenberg blocks and ACF to support large-scale, flexible publishing workflows.
- Managed zero-downtime CI/CD deployment pipelines and maintained absolute production stability across Git-based Linux and Docker environments.
- Integrated AI-assisted development workflows (Copilot/Claude/Cursor) to automate boilerplate code generation, expedite debugging of complex hook interactions, and write comprehensive PHPUnit test suites, achieving a 3x velocity multiplier.
Software Engineer (WordPress)
- Built custom WordPress themes and plugins from scratch utilizing clean OOP PHP, MySQL, and modern JavaScript (ES6+).
- Architected complex backend functionality using the WordPress Hook system (Actions/Filters), custom post types, taxonomies, and optimized custom WP Queries.
- Engineered secure, asynchronous third-party REST API integrations to seamlessly connect WordPress ecosystems with external CRMs (Salesforce, HubSpot) and payment gateways.
- Managed sprint tasks and collaborative code reviews in Agile environments utilizing Git, Jira, and structured staging/production environments.
Backend Developer (PHP / WordPress)
- Developed and maintained custom WordPress websites and plugins with focus on scalability, security, and performance.
- Improved Core Web Vitals, SEO, and user experience through backend and template-level optimizations.
- Diagnosed and resolved critical database bloat by writing custom SQL queries to purge legacy revision data and enforcing strict revision limits, which permanently restored visual editor functionality and reduced query overhead.
Backend Developer
- Maintained and optimized multiple university web platforms for performance and uptime.
- Developed admission portals using Laravel and Vue.js to improve enrollment workflows.
- Translated high-fidelity design mockups into a responsive, pixel-perfect frontend using HTML5, CSS3, and JavaScript to deliver an intuitive, user-friendly experience.
