What I sell

Distributed Systems, DDD & Sane AI Adoption

I help teams design event-driven, domain-aligned systems with CQRS and event sourcing — and adopt AI across the SDLC without losing engineering judgment. Primary focus on messaging, observability, and long‑term system evolution.

AI-Assisted SDLC & Sane AI Adoption

Adopt AI across your software lifecycle without losing engineering judgment. Independent reviews of AI-generated systems and adoption strategies that make AI an amplifier for your engineers — not a replacement. Use AI for the boring 70% and guard the 30% where the engineering lives. I'm not theorizing — I spend my days inside a team building AI-SDLC tooling, and my side projects building my own. I've seen where it goes wrong from the inside.

AI SDLC reviews: specs, plans, and AI-generated code audited by a human architect
Deterministic guardrails and validation gates around nondeterministic LLM components
Spec-driven development enablement: workflows, skills, and agent harnesses for your teams
Skill-atrophy prevention: verification culture, review discipline, and junior protection

DDD, Context Mapping & Event Storming

Strategic and tactical DDD to align software with business reality. Facilitation and modeling to clarify bounded contexts and integration contracts.

Context mapping & bounded contexts
Event Storming (Big Picture, Design‑Level, Software Design)
Tactical DDD: aggregates, value objects, services
Governance: contracts, versioning, evolution maps

Distributed Systems Architecture

Design messaging‑heavy, resilient platforms using CQRS, event sourcing, and topology‑aware routing with strong delivery guarantees.

CQRS, event sourcing, sagas
Contracts and schema governance (JSON Schema)
Messaging: Kafka, RabbitMQ, SQS/SNS
Observability: OTEL tracing, Prometheus, Grafana

Modernization & Enablement

Evolve monoliths into modular systems and enable teams with strong engineering practices.

Strangler Fig migrations, anti‑corruption layers
Architecture reviews, hiring, mentoring, workshops
Engineering standards and delivery governance
Platform enablement: CI/CD, IaC, workflows

Architecture Validation & Due Diligence

Independent reviews and improvements targeting reliability, compliance, and operability across services.

Architecture and resilience audits
Observability, SLOs, audit readiness
Due diligence for acquisitions and replatforming
Governance standards and versioning
Track record

Selected engagements

No logos, no name-dropping — but these were real systems with real stakes.

Entertainment platform, 50M+ users

Problem: a monolith serving tens of millions of players needed to become event-driven without a stop-the-world rewrite. What I did: led the architecture transition, establishing patterns for scalability, observability, and maintainability across teams. Outcome: a mission-critical distributed system running in production at that scale.

Distributed payment platform

Problem: a payment/billing platform needed traceability and audit-readiness without sacrificing throughput. What I did: designed a unified transactional model with event sourcing and decoupled service orchestration via messaging, running on 600+ Kubernetes pods handling millions of euros a month.

Banking web applications

Problem: customer-facing banking applications had to meet strict security and compliance requirements. What I did: built responsive interfaces integrated with banking APIs and payment systems in a regulated environment. Scale and stakes were real; I don't have a public outcome metric to quote here.

Process

How We Work Together

No methodology theater. Three steps.

1

Look

I read your code, your architecture docs, and your incident history before I form an opinion.

2

Work

Alongside your team, in your codebase, respecting the constraints you actually have.

3

Leave

You keep the skills, the docs, and a system your own engineers can explain. I'm not building a dependency on me.

Got a system nobody can fully explain?

Whether it grew that way over ten years or an AI generated it last sprint — I can help. First call is free and I'll tell you if I'm not the right person.
