Accomplished Backend Engineer with over 4 years of experience specializing in Node.js, NestJS, and Spring Boot environments. Proven expertise in architecting scalable microservices architectures and managing complex cloud infrastructures across AWS and DigitalOcean. Highly proficient in delivering high-impact regional solutions, including smart parking systems for Singapore and Malaysia and fintechintegrated self-storage platforms.

Throughout my career, I have focused on building high-performance systems and managing complex data environments. My technical background aligns closely with the requirements of this role:

Backend & API Expertise: Extensive experience developing robust APIs (RESTful) and microservices using Python and Node.js/TypeScript. I have a strong foundation in designing efficient database schemas and managing migrations across PostgreSQL and RDS.

AWS & Cloud Infrastructure: I have hands-on experience with a broad range of AWS services, including EC2, S3, RDS, Lambda, and ECR. I am proficient in containerization using Docker and Docker Compose to ensure seamless deployment and environment consistency.

DevOps & Integration: I am highly skilled in automating deployment pipelines via GitHub Actions and have experience managing both containerized environments and bare-metal microservices.

Full-Stack Capability: Beyond backend logic, I bring a solid understanding of TypeScript and modern frontend principles, ensuring that the integration layers between the UI and backend services are efficient and responsive.

I have a proven track record of taking end-to-end ownership of projects—from initial concept and database design to CI/CD automation and production monitoring. I am particularly interested in applying my experience in microservice orchestration and secure API design to the challenges of financial workflows and lending domains.
