I built a queue service from scratch and learned the hard parts the real way: exponential backoff, contention between workers, and how job claiming should work when multiple queue instances run at once.

How I wired up full observability for my Go gRPC job queue system: metrics with Prometheus, dashboards with Grafana, and distributed tracing with OpenTelemetry and Jaeger.

Different suppliers, different data structures. Built a Go pipeline to normalize, ingest, and monitor 50K+ products using concurrency and batch inserts.

what i learned building senimaya.com, where the real challenge wasn’t building it but convincing people to pay for it.

after years in Etiqa, i faced the classic crossroads: stay in technical team or move to product team? this post explores the challenges, trade-offs, and unexpected lessons.
