01/03The Discovery
DDD by design
I run collaborative discovery — event storming, impact mapping, example mapping — so product, business and devs share one model of the domain. Devs sit with the client; domain understanding flows back into the code.

Ship what the business actually needs.
Tech lead & educator with 13+ years in the trenches. I wire strategic & tactical DDD, TDD and Clean Architecture into teams — and I design delivery pipelines where AI agents do the derivable work, so humans focus on what's scarce: business judgment.

01/04The Approach
Build what the
business needs
Strategic & tactical DDD, TDD, Clean Architecture — with a product, agile and devops culture on top. My job is to close the distance between a decision and the evidence about it.
I facilitate collaborative discovery so product, business and devs share a single model of the domain — and build what has real value, not just what is feasible. Then I bring domain understanding down into the code: bounded contexts, ubiquitous language, vertical slices.
Operating principle
“When you can build the wrong thing 10× faster, the discipline that tells you it’s wrong becomes more valuable, not less.”

02/04The Craft
Three pillars
Discovery to derive the right thing. Architecture to build it so it lasts. An agentic pipeline to ship it, iteration after iteration.
02/03The Architecture
Deterministic craft
Clean Architecture / Ports & Adapters, tactical DDD, CQS and modular monoliths with vertical slices. Write models local to the command, concurrency handled at the infra edge. Business rules as pure functions — tested, provable, boring in the best way.
03/03The Delivery
Road to the dark factory
Business judgment is expensive and rare — everything else can be derived. I build delivery pipelines that move toward the dark factory: the pipeline is a graph where agents live in the nodes that require judgment and deterministic verdicts sit on every edge. A user story flows from specification to shippable PR; humans stay at both ends — framing the need upstream, validating the result downstream.

Where I’ve shipped
Tech Lead @ Plop.
Tech lead on applications for industrial clients — from product framing to delivery. Driving the shift toward autonomous delivery: an agent graph produces, deterministic gates verify, humans decide.
