Web Applications
Modernized a legacy enterprise system for connectivity management into a cloud-native platform.
What it does: Manages connectivity data across distributed systems, with high-performance data exports and centralized observability for production monitoring. How it was built: Java 25 + Next.js frontend, PostgreSQL with Flyway migrations, GraphQL for front-to-back communication, AWS infrastructure (Lambda, SNS, SQS, EC2, RDS, S3) provisioned via Terraform, and Grafana/Loki/Promtail for logging and observability. What I learned: End-to-end legacy migration strategy; slashing query execution time 76% via database projections and streaming; cutting AWS costs 12% through architectural reviews and resource right-sizing; reducing MTTR with centralized observability tooling.
