Project history
Delivered a community platform for soft tip dartboard players using Next.js, React, Redux, Tailwind CSS, Supabase serverless functions, and PostgreSQL. Implemented serverless architecture to optimize infrastructure costs and improve scalability. Managed complex state with Redux and designed normalized PostgreSQL database schemas.
Delivered a microservices-based logistics tracking platform using AWS Lambda and AWS Batch Jobs. Led refactoring of repository layer, set up containerized CI/CD pipelines with Docker and GitHub Actions, developed inventory automation modules with PostgreSQL and AWS RDS, designed secure RESTful APIs with OAuth2, and integrated observability dashboards using Grafana. Automated test coverage using Jest, Cypress, and Playwright achieving 85% test coverage.
Enabled zero-downtime deployments by designing a custom deployment pipeline using AWS EC2 launch templates and AWS Secrets Manager. Configured GitHub Actions for CI/CD automation, reducing deployment time by 40%. Built and maintained a cloud-native asset-creation dashboard using React, Tailwind CSS, Node.js, and TypeScript. Implemented backend API endpoints using Express.js and supported continuous improvement through code reviews and sprint retrospectives.
