Haidar Saifaldeen

I’m a Senior Full Stack Developer with over 5 years of professional experience delivering high-quality software solutions in both FinTech and digital agency environments. My work spans the full development lifecycle—from gathering requirements and planning architecture to deploying and maintaining robust applications in production.

I specialize in building modern web applications with Laravel on the backend and React on the frontend. My Laravel expertise includes building RESTful APIs, implementing secure authentication and authorization systems, integrating with payment gateways, and optimizing performance for high-traffic platforms. On the frontend, I develop clean, maintainable React components with a focus on user experience, performance, and responsiveness.

In addition to full-stack web applications, I have extensive experience in WordPress development, having built and maintained over 20 custom websites for a variety of industries. This includes developing custom WordPress themes from scratch, creating and extending plugins, implementing WooCommerce for eCommerce solutions, and managing SEO and performance optimization. I'm comfortable with both traditional WordPress and headless setups using WP as a backend CMS.

My technical skill set includes:

• Languages/Frameworks: PHP, JavaScript (ES6+), Laravel, React, HTML5, CSS3, TailwindCSS, Alpine.js
• CMS & Platforms: WordPress, WooCommerce, ACF, Elementor, Gutenberg
• APIs & Integrations: REST, third-party APIs (e.g., payment, CRMs, analytics), OAuth, Webhooks
• Tools & DevOps: Git, Docker, NGINX, Composer, Laravel Forge, CI/CD, MySQL, Redis
• Testing & Quality: PHPUnit, Laravel Dusk, Postman, Lighthouse for performance and accessibility

I have a solid track record of collaborating with cross-functional teams, mentoring junior developers, and working in Agile environments to deliver solutions that align with business goals and user needs. My background in FinTech has made me comfortable working with secure, regulation-compliant codebases, while agency experience has taught me how to adapt quickly, meet tight deadlines, and manage multiple client projects.

I'm passionate about writing clean, scalable code, learning new technologies, and contributing to meaningful digital products. Whether it’s building an investment dashboard, a lead-generation platform, or a fully custom CMS, I approach every project with a balance of technical precision and creative problem-solving.
