What I'm looking for

I seek backend-focused roles where I can build scalable Laravel/PHP systems, write clear documentation, work in cross-cultural teams, and grow into technical leadership.

I am a senior backend developer with 5+ years of professional experience building web applications using PHP (Laravel), JavaScript, and related technologies, and I communicate effectively in English, Tamil, and Japanese (JLPT N4). I have delivered backend systems for HRMS, e‑commerce-style inventory and billing, educational platforms, booking systems, and several industry-specific applications.

I focus on building maintainable server-side solutions, designing detailed documentation and unit test specifications in English and Japanese, and improving product efficiency through role-based access, real‑time features, and optimized admin workflows.
