What I'm looking for

I am looking for a remote full-stack, frontend, or backend engineering role with a product-focused team in Singapore or across APAC. I value clear communication, ownership, maintainable code, and opportunities to build scalable applications and APIs while continuing to grow technically and mentor others.

Full-Stack Developer and Technical Lead with hands-on experience delivering responsive web applications, backend services, third-party API integrations, and business automation systems across LMS, HealthTech, marketplace, e-procurement, and finance operations.

I work across the full delivery lifecycle—from requirements gathering and system architecture to implementation, code review, debugging, and stakeholder communication. My stack includes Laravel, React, Next.js, Vue.js, Nuxt.js, Express.js, NestJS, Go, TypeScript, MySQL, PostgreSQL, and MongoDB.

I have built marketplace and enterprise applications, implemented Progressive Web Apps and Trusted Web Activity deployments, and collaborated directly with clients and cross-functional teams. I also mentor and teach full-stack development, and I am comfortable working remotely and adapting quickly to new codebases.
