What I'm looking for

I seek a collaborative, agile team where I can lead front-to-back projects, optimize performance, adopt DevOps practices, and mentor engineers.

I am a Full Stack Developer who builds scalable, high-performance applications using modern technologies such as React, Next.js, Node.js, NestJS, MongoDB, and PostgreSQL, with a strong focus on workflow automation and performance optimisation.

I've led UI development for lending and financial platforms, improved build performance by 40% through Vite adoption, migrated and redesigned apps to Next.js to reduce load times, and contributed to products that served thousands to hundreds of thousands of users.

I bring an ownership mindset, advocate for clean maintainable code, and mentor aspiring engineers while deepening expertise in AWS and CI/CD to support DevOps-aligned delivery.
