Oliver K.
Last position:
Founder & AI Automation Architect at Zerobits
Zerobits is my vehicle for AI-powered automation and custom software development with a clear principle: AI solutions that reach production, not pilot stage. I design and build the systems myself - from first concept and architecture through implementation to deployment and operations.
My focus is on replacing repetitive, manual work with reliable automation and connecting disconnected tools and data sources into one dependable overall system.
Selected work:
- Design and implementation of LLM-based agent systems and RAG pipelines (Anthropic Claude, Mistral, MongoDB Atlas Vector Search + RAG)
- Workflow orchestration for long-running, fault-tolerant business processes using Temporal (temporal.io): saga patterns, event-driven architecture, retry and compensation logic, connecting third-party APIs and internal services into automated end-to-end processes
- Full stack product development: SaaS architecture on Kubernetes, TypeScript/React/NestJS, admin tooling with refine.dev and MUI
- AI-assisted development workflow as standard practice to deliver production software at a fraction of traditional timelines
- Full stack product development: multi-tenant SaaS architecture running on Kubernetes, backend with NestJS/Node.js and Python, frontend with TypeScript, React and Next.js, admin tooling with refine.dev and MUI, CI/CD with GitHub Actions
One of these projects is a product I own and operate - free of any NDA restrictions. I'm happy to demonstrate it end to end.

About the technology
What the Saga Pattern solves
The Saga Pattern manages business transactions that span several independent services. Instead of one database transaction, it divides the workflow into local transactions connected by events or commands. Each completed step has a compensating action that can undo or offset its business effect when a later step fails.
Choreography and orchestration
A choreography-based saga lets services react to domain events without a central coordinator. An orchestration-based saga uses a dedicated coordinator to direct each step and track state. Strong designs choose deliberately between these approaches, considering coupling, visibility, failure handling and the number of participating services.
Typical implementation work
- Model business workflows and transaction boundaries
- Define events, commands and compensating actions
- Implement orchestration with workflow engines or application services
- Add retries, timeouts, idempotency and dead-letter handling
- Trace saga state across distributed services
Common ecosystems include Kafka, RabbitMQ, REST and gRPC, alongside Spring Boot, .NET and cloud-native service stacks. Persistence may involve SQL databases, document stores and an outbox pattern for reliable event publication.
When companies need specialists
Companies usually bring in freelance expertise when a monolith is being split into services, a cross-service order flow is becoming unreliable, or distributed transactions are creating operational risk. Germany-based teams may also need support that fits established on-site processes, remote collaboration models and local language expectations. The work often includes architecture reviews, proof-of-concept implementations and production migration plans.
Skills that distinguish strong experts
Good specialists understand domain-driven design, event-driven architecture and the practical limits of eventual consistency. They make workflows observable, keep compensation actions safe, and design for duplicate messages, partial outages and replayed events. They also explain trade-offs clearly to product, operations and service teams instead of treating the pattern as a universal replacement for ACID transactions.
Evaluating delivery quality
Review how an expert models failure paths, not only the successful business flow. A sound solution documents invariants, ownership, timeout policies, retry limits, idempotency keys and recovery procedures. Ask for a clear testing strategy covering service outages, message duplication, delayed events and compensation failures. The result should be measurable through logs, traces, saga state and operational alerts.
Frequently asked questions
Key details about Saga Pattern, drawn from the questions we get asked most.
The Saga Pattern coordinates a business transaction across multiple services without requiring one distributed database transaction. It is useful for workflows such as order placement, payment, inventory reservation and shipment, where each service commits its own local change. Compensating actions help restore a valid business state when a later step cannot complete.
The Saga Pattern favors local commits and eventual consistency, while two-phase commit tries to keep participating resources in one coordinated transaction. Sagas can improve service autonomy and availability, but they require explicit compensation, recovery and observability. Two-phase commit may offer stronger consistency for suitable infrastructure, yet it can increase coupling and coordination overhead.
A Saga Pattern can use choreography, where services respond to events, or orchestration, where a coordinator directs the workflow. Choreography can stay lightweight but becomes difficult to understand as dependencies grow. Orchestration offers clearer control and monitoring, though the coordinator must be designed to avoid becoming a fragile central dependency.
A strong Saga Pattern specialist should understand domain-driven design, event-driven architecture, messaging systems and distributed tracing. Practical knowledge of Kafka, RabbitMQ, REST, gRPC, the transactional outbox and idempotent processing is valuable. They should also be comfortable with cloud operations, automated testing and incident recovery.
A Saga Pattern project needs more than familiarity with event publishing. The specialist should have handled failure modes such as duplicate messages, timeouts, partial completion and failed compensations in systems with meaningful business consequences. The required depth depends on workflow complexity, service boundaries and the operational maturity of the team.
Yes, Saga Pattern work can usually be delivered remotely when architecture decisions, service contracts and operational ownership are documented. Teams in Germany may prefer German-language collaboration or periodic on-site workshops, depending on internal processes. Remote work still requires close access to repositories, observability tools and the people responsible for each participating service.
Evaluate whether the Saga Pattern design makes every state transition, timeout and compensation explicit. Look for idempotency, bounded retries, durable state, traceable correlation IDs and tests for outages and reordered messages. A quality design also states where eventual consistency is acceptable and how operators recover incomplete workflows.
The Saga Pattern is a poor fit when a short, single-database transaction can enforce the required invariants more simply. It is also risky when compensation cannot safely reverse a business action or when the team lacks monitoring and operational ownership. A specialist should compare it with local transactions, redesigning service boundaries or other workflow approaches before recommending adoption.
