Engineering leaders tired of flying blind during production incidents or paying runaway Datadog bills frequently search to hire a freelance OpenTelemetry, Prometheus, Grafana, Loki & SRE observability programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack & Cloud Infrastructure Programmer available via Upwork.

Core Observability & Site Reliability Engineering (SRE) Capabilities

  • Vendor-Neutral OpenTelemetry (OTel) Instrumentation: Tracing distributed requests end-to-end across Next.js, FastAPI, Django, Go microservices, Celery workers, and PostgreSQL queries.
  • Grafana LGTM Stack (Loki, Grafana, Tempo, Mimir/Prometheus): Deploying cost-effective self-hosted or Grafana Cloud observability stacks that cut Datadog/New Relic spend by 60–80%.
  • Actionable SLO Alerting & Runbooks: Eliminating alert fatigue with error-budget burn-rate alerts routed to PagerDuty, Opsgenie, or Slack.

Frequently Asked Questions

Can a freelance programmer reduce our monthly Datadog bill without losing visibility?

Yes. I audit high-cardinality custom metrics, filter noisy container logs at the OpenTelemetry Collector layer, or migrate your telemetry to Grafana Cloud / Prometheus.

How can we hire you for OpenTelemetry and SRE engineering?

Contact me on Upwork.
