Built a custom dashboard aggregating SNMP traps, syslog feeds, and environmental sensor data. Integrated with PagerDuty for on-call escalation and provided historical trend analysis for capacity planning. The system monitors over 800 network devices in real time.

Designed and built a lightweight workflow engine that listens for domain events, routes tasks to the right handler, and tracks execution state. Replaced 30+ fragile cron scripts with a single observable system. Includes a web UI for ops teams to inspect and retry failed tasks.

Built a translation layer that maps legacy ERP data models to clean REST and event-driven APIs. Enabled the client's mobile app and e-commerce platform to consume real-time inventory data without modifying the core ERP. Processes over 50,000 transactions per day with sub-second latency.

Conducted full predictive and validation site surveys across six buildings including a foundry and paint shop. Designed antenna placement to account for metal racks, moving forklifts, and high-temperature zones. Delivered seamless roaming for handheld scanners and VoIP handsets with 99.9% uptime.

Migrated 12 microservices from a single Jenkins instance to GitHub Actions with reusable workflows, ephemeral build runners, and Terraform-managed infrastructure. Added automated integration tests, security scanning, and canary deployments. Average deploy time dropped from 45 minutes to 8 minutes.
