Profile
Lead Software Engineer with 25 years building production software across real estate SaaS, banking, insurance and telecommunications, the last six fully remote across immowelt, Empro and now Whise. My team builds and maintains an agentic SDLC platform of AI agents on large language models (LLMs), with a harness of Claude skills, commands, hooks and rules that engineers work through daily. That background is why it holds up in production: domain-driven design and event-driven serverless architecture on AWS, alongside Azure Kubernetes and PostgreSQL.
Key Project: AI-assisted build of a real estate CRM
Our team is building a new web and mobile real-estate CRM, migrating functionality out of legacy systems, and we built and maintain the agentic SDLC that delivers it.
Harness layer. The Claude skills, slash commands, hooks and rules the team works through, with Model Context Protocol (MCP) servers and RAG retrieval connecting agents to repositories, pipelines and issue tracking.
How it runs. A stakeholder-approved prototype enters the pipeline through specification extraction; agents then groom, implement, review and test, with hooks and rules enforcing standards so throughput does not turn into verification debt.
Reach. Used daily across our 11-person cross-functional team: 6 developers, 2 QA engineers, 2 product owners and a scrum master.
