Events your systems fire, delivered and confirmed — every time.
I build outbound and inbound webhook infrastructure that doesn't silently drop events: signed payloads, retry with backoff, dead-letter queues, and logs you can actually audit when a customer asks "did that go through?"
Delivery Bench
Pick an event and fire it. Watch it get signed, sent, and — if the endpoint misbehaves — retried on a real backoff schedule.
X-Webhook-Signature: sha256=…
No events fired yet. Choose one on the left and press "Fire test event."
how it holds together
Three things separate a webhook that works from one that quietly fails
Firing an HTTP request on an event is the easy 10%. The reliability comes from what happens around it.
Event source
A domain event — an order placed, a payment settled, a build finished — captured the moment it happens and queued, not sent inline from the request that caused it.
Retry & backoff
Failed and timed-out deliveries are retried on an exponential schedule with jitter, up to a cap, then routed to a dead-letter queue instead of vanishing.
Signatures & idempotency
Every payload is HMAC-signed so the receiver can prove it came from you, and carries an idempotency key so a retried delivery never double-processes.
what I build
Webhook systems, both directions
Whether you're sending events out to customers or consuming them from a platform you don't control.
Webhook delivery infrastructure
Queue-backed dispatch, signing, retry policy, and a delivery log your support team can search when a customer says an event never arrived.
Webhook receivers
Endpoints that verify signatures, deduplicate by idempotency key, and hand off processing to a queue so a slow handler never times out the sender.
Stripe, Shopify, WooCommerce, GitHub
Integrating the webhook conventions of the platforms you already run on, including their specific signature formats and event ordering quirks.
Retry, backoff & dead-letter design
Backoff schedules tuned to the failure mode, alerting when a dead-letter queue grows, and a replay path for reprocessing once an endpoint is fixed.
n8n, Make & workflow platforms
Wiring webhooks into n8n or Make as the trigger for multi-step automations, or replacing brittle no-code flows with a maintained custom pipeline.
Delivery logging & alerting
A searchable record of every attempt — payload, response code, latency, retry count — plus alerts when delivery success rate drops.

How a webhook build runs
Same sequence every time, because reliability work rewards being methodical.
Map the events and consumers
List what should fire a webhook, who consumes it, and what happens on their end if a delivery is late, duplicated, or never arrives.
Design the payload and signing scheme
A stable payload shape, an HMAC signing convention, and an idempotency key strategy — decided before any code, since it's expensive to change later.
Build the queue-backed dispatcher
Events are captured and queued immediately, then dispatched asynchronously with retry and backoff — so a slow receiver never blocks the sender.
Load-test failure paths
Deliberately breaking the receiving endpoint to confirm retries, backoff timing, and dead-letter routing behave the way the design says they should.
Ship with logging and a replay path
Deployed with a searchable delivery log and a way to replay a failed or missed event on demand, plus a short handoff doc for your team.

questions
Frequently asked
What happens if our endpoint is down when a webhook is sent?+
The delivery is retried on an exponential backoff schedule — typically a few attempts over several minutes to a few hours, depending on how time-sensitive the event is — before it's routed to a dead-letter queue for manual or automatic replay once the endpoint is back.
How do you prevent an event from being processed twice?+
Every payload carries an idempotency key. Receivers are built to check that key before processing, so a retried delivery — which is expected and normal — never results in a duplicate charge, duplicate email, or duplicate order.
Can you verify webhooks from platforms we don't control, like Stripe or Shopify?+
Yes — each platform has its own signature scheme and header format. I build the verification and parsing for the specific platforms you're receiving from, so unsigned or spoofed requests are rejected before they reach your business logic.
We're using Zapier or Make right now — is it worth replacing?
Often not entirely. Low-volume, non-critical automations are usually fine left where they are. It's worth moving to custom infrastructure when volume, cost, or reliability requirements outgrow what the no-code platform guarantees — I can help you figure out which is which.
How do you handle out-of-order delivery?
Where order matters, each event carries a sequence number or timestamp and the receiver is built to either process in order or reconcile against current state rather than assuming delivery order matches event order — because most webhook systems don't guarantee it.
What does a typical webhook automation project cost and take?
A single outbound or inbound integration with proper retry and signing usually takes one to two weeks. Multi-platform systems with dead-letter handling and observability take longer. I'll scope it precisely after a short discovery call.
