Full-stack feature delivery
End-to-end ownership of multi-week features: discovery, RFC authoring, scope planning, implementation across a TypeScript/Angular frontend and a Node.js/NestJS + PostgreSQL backend, feature-flagged rollout, and production operation.
Cloud infrastructure & deployment
Designing and operating production stacks on AWS (EKS, S3, CloudFront, ALB, SQS, DynamoDB) with Helm, Terraform, and Cloudflare. Comfortable owning the path from local dev to production rollout.
Production reliability & observability
Diagnosing and fixing reliability issues in Node.js services on Kubernetes — memory pressure, OOMs, resource limits, flaky CI — using Datadog for observability and targeted refactors to remove root causes.
IoT & edge integrations
Building integrations between cloud services and physical industrial devices over MQTT and AWS IoT Core, including legal-compliance features for regulated markets.
