Engineering case studies
Real systems, real trade-offs — architecture decisions, challenges and measurable outcomes.
Distributed Tracing Platform with OpenTelemetry
End-to-end observability for a polyglot microservices app — tracing latency and bottlenecks across services with OpenTelemetry, then visualising the data for fast root-cause analysis.
GitOps Platform on EKS with Terraform & Argo CD
A reproducible, self-service Kubernetes platform: infrastructure defined in Terraform, applications delivered via Argo CD, and every change flowing through pull requests.
Self-Healing, AI-Augmented CI/CD Pipeline
A delivery pipeline that triages its own failures: when a build or deploy breaks, an LLM step classifies the root cause, suggests a fix, and auto-retries transient errors before paging a human.
