Presentation
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.
