Backends that hold up
Laravel, Spring Boot, and Node.js APIs designed for real traffic — clean data models, safe queries, and resilience against the messy edge cases that only show up in production.
DevOps & zero-downtime releases
AWS infrastructure with Docker and Kubernetes pipelines, CI/CD via GitHub Actions and fastlane, and release cadences measured in days — with zero downtime and a 99.9% uptime line held in production.
Proof
Dispatch Pro runs on a Spring Boot + Kafka pipeline on AWS with releases every few days. QistLock is a NestJS SaaS running live. I've kept fleets of apps at 99.9% uptime.
