What I'm looking for

I’m looking to build scalable SaaS and API-driven platforms, partnering with product teams on microservices, performance optimization, and secure integrations—using test-driven development and clean architecture to deliver production-ready results.

I’m a Senior Full Stack / Laravel Backend Developer with 5+ years of experience building scalable SaaS platforms, CRMs, and API-driven systems. I bring strong expertise in modern PHP and Laravel/Symfony ecosystems, with a focus on delivering production-ready features that hold up under real-world load.

At Exec9, I designed and developed scalable Laravel applications using service-based architecture and microservices. I integrated payment gateways (Stripe, PayPal), built OTP and notification APIs (Twilio, Plivo, SimpleTexting), and implemented OpenAI (ChatGPT) for AI-powered automation inside SaaS products.

Now at Elevex, I develop full-stack features using the Symfony framework and modern PHP best practices. I work with MongoDB for schema design, data modeling, and query optimization, and I maintain unit tests to reduce regression risk—while collaborating in agile workflows through Jira and GitHub.

Across earlier roles, I built RESTful APIs for frontend and third-party integrations, developed WordPress-based business platforms and custom plugins, and contributed to backend standards through code reviews and SOLID principles. I also prioritize security (JWT, OAuth2, RBAC, CSRF protection) and use AI-assisted development tools to accelerate delivery without compromising code quality.
