10 years of backend automation, API testing, and C# — applied to building reliable AI agents, n8n workflows, and automation systems that actually work in production.
After a decade breaking backend systems on purpose — testing APIs, automating integration pipelines, and hunting edge cases in C# — I'm applying that same rigour to AI agents.
Most AI automation breaks in production. I build it so it doesn't. Currently deepening my expertise through the MASC course on agent architectures, complementing years of hands-on automation engineering.
C#, REST APIs, backend integration testing, CI/CD pipelines
n8n workflows, LLM orchestration, tool-use agents, MASC
Every agent is built with assertions, monitoring, and fallbacks
No prototypes. Only automation that runs and earns.
AI automation systems designed with an engineer's attention to edge cases, reliability, and observable outcomes.
Custom AI agents that use tools, make decisions, and execute multi-step workflows autonomously — with built-in guardrails and observability.
Production-grade n8n automation pipelines: CRM sync, data enrichment, multi-step approval flows, error handling, and monitoring.
Automated test frameworks, API contract testing, integration test suites, and CI/CD pipelines — making quality non-negotiable.
Connecting AI agents to real business tools: CRMs, email, Slack, databases — automating repetitive work without breaking existing processes.
Deep expertise in REST API design, contract testing, mocking, and integration — ensuring AI agents talk to external services reliably.
Helping teams identify automation opportunities, design reliable systems, and avoid the common pitfalls that make AI automation fragile.
Every project follows the same disciplined approach — because automation that isn't tested will break.
Map the process, identify failure points, define what "done" looks like
Architect the automation with fallbacks, monitoring, and edge case handling
Iterative development with assertions at every step — not just "it ran"
Production deployment with observable logs, alerts, and continuous improvement
