Product frontends
Next.js and React interfaces with responsive layouts, meaningful metadata, accessible navigation, and production-oriented user flows.
Full-Stack Engineering
Full-Stack Engineering Portfolio
I build full-stack applications across product UI, backend APIs, databases, cloud infrastructure, and deployment workflows. My work emphasizes practical systems: tools that organize data, automate operations, and make technical workflows easier to use.
What I Build
Backend and data systems
APIs, relational data models, serverless functions, background jobs, and data processing pipelines that support real workflows.
Cloud deployment
Vercel and AWS deployments using Lambda, API Gateway, S3, DynamoDB, RDS, Docker, and GitHub Actions where they fit the product.
Representative Systems
Real-Time IoT Mailbox Monitoring System
ESP32-CAM firmware, Next.js backend, MySQL, AWS S3, and alert workflows for mailbox access events.
CareerOS / CareerX Inbox
Next.js product surface and backend-oriented workflow architecture for recruiting inbox operations and follow-up tracking.
AWS Serverless Ride-Sharing Demo
Amplify, Cognito, API Gateway, Lambda, and DynamoDB implementation of a full serverless web application pattern.
