Legacy .NET rescue: stabilize production first
Fix hangs, timeouts, starvation, and retries that duplicate work — with practical instrumentation and safe changes you can ship.
Lane A
Symptoms I fix
- • Background jobs hang forever
- • Thread pool starvation and slow APIs
- • Retry storms and duplicate side effects
- • “Works locally” but flakes in prod
What you get
A diagnosis ladder, minimal-risk fixes, and the exact logs/metrics to prevent the same outage next week.

Crypto exchange rate limiting: fixed window vs leaky bucket (stop 429s)
A production-first playbook to stop 429 storms: diagnose the limiter type, add guardrails, and log the signals you need to stop guessing.
Handling 429s and Retry-After correctly in HttpClient
A production playbook for honoring Retry-After and stopping retry amplification when a dependency throttles your .NET service.

Correlation IDs in .NET: trace one request across services and jobs
A production playbook for a single correlation ID contract in .NET so requests and jobs can be traced end-to-end across boundaries.

The real cost of retry logic: when “resilience” makes outages worse
Retry storms don’t look like a bug — they look like good engineering until production melts. Here’s how to bound retries with stop rules and proof.

Timeouts first: why infinite waits create recurring outages in .NET
Infinite waits do not look like crashes. They look like calm dashboards and growing backlog. This is the production playbook for adding time budgets safely in .NET.
Why your background jobs hang forever (and no one notices)
Queues and scheduled jobs fail quietly: missing timeouts, missing heartbeats, and retries that hide failure. A practical runbook-style playbook for .NET systems.

Resources
All resourcesHttpClient 429 + Retry-After package
A copy/paste handler that parses Retry-After (seconds and HTTP date) plus a 429 runbook and logging fields so throttling becomes bounded, observable, and non-amplifying in .NET.
Correlation IDs package (HTTP + jobs)
A correlation ID contract plus copy/paste ASP.NET Core middleware and an HttpClient handler so correlation survives HTTP and background job boundaries and incidents become one-query diagnosable.
Axiom
Axiom Ops — reliability defaults + runbooks
A practical kit to stop loops, prevent duplicate side effects, and make failures obvious.
XConnect — turn X DMs into a real pipeline
A lightweight CRM + DM workflow inside X so you can capture prospects, organize leads, and send consistent follow-ups without losing context.
This week
Want help this week?
If you have a production incident, recurring timeouts, or jobs that get stuck overnight, I can help you stabilize first.
What we do in the first 48 hours
- • Confirm the failure mode + the repeat trigger
- • Add the minimum logs/metrics to prove the fix
- • Ship 1–2 safe changes that stop repeats

Founder & Lead Engineer
I help teams keep automation and .NET systems stable in production: stop duplicate side effects, fix retry storms, make failures observable, and ship guardrails fast. If you’re dealing with 429s, timeouts, runaway jobs, or “it fails but the logs don’t say why”, I’ll help you stabilize first and then harden so it stays fixed.
