I build scalable backend APIs and real-time web applications.

What I'm looking for

I'm looking to build scalable APIs and backend systems, own architecture end-to-end, collaborate with clients and frontend teams, and guide developers through integration, debugging, and delivery.

I've spent 3+ years building and maintaining PHP/Laravel REST APIs for an Australia-based real estate platform, supporting bidding, legal processes, document management, internal communication, and an in-house e-signature solution. I also managed AWS EC2, S3, and RDS infrastructure and worked directly with international clients to turn business requirements into technical solutions.

Currently, I'm developing Python/FastAPI backend services for transport and event-management applications, including multilingual APIs and WebSocket-powered real-time features. I guide frontend and backend developers through API integration, code reviews, debugging, and delivery across React and React Native applications.
