Hubertus S.
Last position:
Senior Product Manager AI
Workflow-automation SaaS for operations teams (Berlin, 120 people); full-time freelance engagement reporting to the CEO: an initial 12-month interim mandate, extended twice through the AI build-out; owned product for one squad and coached the other product managers on process.
- Led generative AI (LLM) integration into the core product: from LLM-powered steps to natural-language workflow authoring and step-level automation suggestions, plus AI-managed dynamic workflows, shipped behind eval gates with human-in-the-loop fallbacks: AI-drafted workflows grew to 31% of all new workflows, and median time-to-first-workflow fell from 3 days to 4 hours.
- Packaged the AI capabilities as a usage-based add-on priced on executed automation steps, working with sales and marketing on positioning: ~€800K added ARR in the first year, and adopting accounts churned 1.8 pp less.
- Owned the roadmap end to end: replaced feature-request-driven quarterly planning with an outcome-based rolling roadmap built on quarterly bets and explicit kill criteria, presented monthly to the executive team and quarterly to the board.
- Rebuilt the product-management operating system: weekly customer-discovery cadence incl. workshop facilitation, RFC/decision-doc reviews and a single quarterly metrics narrative; coached four product managers, one promoted to senior during the engagement.
- Closed the engagement as scoped: hired and onboarded the permanent VP Product, handed over the process playbook and roadmap, and exited on schedule in June 2026.

GTM Intelligence Engine · Open Source
- PROBLEM: GTM effort is guesswork across fragmented identities and channels, with no closed feedback loop.
- BUILT: Cost-pyramid engine (L0–L3): identity resolution across ~25k entities, explainable intent scoring, and a closed decision loop (propose → execute → evaluate → learn) with calibration.
- IMPACT: Shipped v1.3.1 with a live demo; 99% of operations resolve at the free L0 tier (CI-enforced); $0 to run without any API key.

About the technology
Event-driven connections
Webhooks are HTTP callbacks sent automatically when an event occurs in one system. They let applications notify one another in near real time instead of waiting for repeated polling requests. Companies use them to connect SaaS products, commerce systems, payment services and internal workflows.
Core integration work
A reliable webhook implementation covers more than sending a request. Specialists define event contracts, authentication, payload schemas and delivery rules, then connect those events to useful business actions.
- Publish and consume event notifications
- Validate signatures and request origins
- Handle retries, timeouts and duplicate events
- Transform payloads between APIs and services
Ecosystem and tooling
Webhooks commonly sit beside REST APIs, GraphQL, message queues and serverless functions. Strong professionals work with JSON, HTTP, TLS, OAuth, HMAC signatures and API gateways, while using logs, tracing and test endpoints to inspect delivery behavior. Stripe, GitHub, Shopify and many other services expose webhook interfaces, each with its own event model.
When expertise matters
Companies often bring in freelance specialists when an integration must move from a quick proof of concept to dependable production traffic. This is especially relevant during payment changes, SaaS migrations, marketplace connections or the replacement of fragile polling jobs.
- Events are missed or processed more than once
- Partners need a clear webhook contract
- Failures are difficult to trace across services
- New integrations must fit existing security controls
Reliable delivery design
Good webhook systems expect delayed, duplicated and out-of-order messages. Professionals build idempotent consumers, durable queues, replay options and dead-letter handling rather than assuming every request succeeds. They also separate acknowledgement from business processing so senders receive a timely response.
For teams in Berlin, remote collaboration is often enough for this work, provided documentation, incident ownership and review practices are clear. On-site sessions can help when specialists need to map complex workflows with product, security or operations teams.
What strong specialists bring
The best Webhooks professionals think across the complete integration path: event design, application code, infrastructure, security and observability. They can explain why a callback failed, prove that sensitive data is protected and make behavior testable for both the sender and receiver.
Ask for examples of event contracts, retry policies, signature verification and monitoring dashboards. A careful specialist will also clarify delivery guarantees, versioning, replay procedures and how the integration behaves during outages.
Frequently asked questions
The facts hiring teams ask for most often when it comes to Webhooks.
Webhooks notify another application when a defined event happens. They are useful for payment updates, order changes, repository events, account provisioning and automated internal workflows, without constant polling.
Webhooks push event information when it is available, which can reduce unnecessary requests and shorten response times. Polling is simpler when a service cannot send callbacks, but it may introduce delays and repeated queries.
Webhooks usually deliver an HTTP request directly from one service to another. Message queues add durable buffering and consumer control, so a robust integration may use a webhook at the boundary and a queue behind the receiving endpoint.
A strong Webhooks specialist should understand REST APIs, HTTP, JSON, authentication, HMAC signatures and API security. Experience with queues, serverless functions, observability and idempotent processing is also valuable.
The right level depends on the risk and scope of the integration. A simple event connection may need focused implementation work, while payment or multi-service flows require proven experience with retries, duplicate delivery, schema changes and incident recovery.
Webhooks work is often well suited to remote collaboration because contracts, payloads, logs and test cases can be reviewed online. On-site workshops can still help when several Berlin-based teams need to map ownership, security requirements and operational processes together.
Webhooks should use HTTPS, verify sender signatures, reject stale or malformed requests and avoid exposing unnecessary data in payloads. Access controls, secret rotation, replay protection and audit logs should match the sensitivity of the events.
Ask how the Webhooks implementation handles retries, duplicate events, out-of-order delivery, timeouts and provider outages. Quality is visible in clear contracts, automated tests, useful monitoring, replay procedures and documentation that another professional can operate.
