IDENTITY
CORE

System Status: OPERATIONAL

// SYSTEM_IDENTITY

I am an AI systems engineer focused on AI systems, not just model demos. I build complete products: backend APIs, storage and retrieval pipelines, auth and security, frontend control planes, testing, documentation, and deployment workflows.

My strength is ownership. I take systems from architecture through validated implementation with clear contracts, tests, and operational checks. I use type checks, linting, security scans, and failure-path tests according to the evidence and risk of each project.

Based in Berlin, I design and document software systems across AI infrastructure, research tooling, automation, and desktop applications. My work spans architecture, backend services, data and retrieval pipelines, security boundaries, frontend control surfaces, testing, documentation, and release workflows. I focus on making ownership, evidence, permissions, and runtime behavior explicit. My background in leadership and operations informs how I approach governance, communication, and delivery. I continue formal study in business and information technology while developing systems through hands-on engineering.

// GOVERNANCE_PROTOCOL

THE METHOD

I use a verification-first engineering workflow. Before implementation, I define the system boundary, the evidence required for correctness, and the checks that protect it. Then I build a complete path and verify expected and failure behavior.

PHASE_01STANDARD

DEFINE

Make the boundaries explicit

▸Clarify the user problem, system responsibilities, and success criteria
▸Map data ownership, tenant boundaries, permissions, and sensitive operations
▸Write the state model, API contracts, storage choices, and failure paths
▸Identify the evidence, numerical, security, and fidelity properties that must remain true
PHASE_02STANDARD

BUILD

Implement the smallest complete path

▸Build vertical slices that connect interface, runtime, storage, and observability
▸When AI can take action, keep model output separate from authority through typed tools, policies, and approval boundaries
▸Use deterministic algorithms where behavior must be reproducible and inspectable
▸Keep integrations modular: providers, connectors, document engines, and execution adapters
PHASE_03REQUIRED

VERIFY

Test the result and the failure paths

▸Run focused unit, integration, acceptance, numerical, and end-to-end checks
▸Record repository-backed evidence from test results, static analysis, security checks, and delivery checks
▸Apply type, lint, and security checks where the repository supports them
▸Exercise retries, stalled streams, rejected actions, tenant isolation, tamper detection, and rollback paths where supported
METHOD_STATUS::REPEATABLE

“A feature is ready when its behavior, boundaries, and failure paths can be inspected.”

FAIM-Native: deterministic memory architecture

Designed a contradiction-aware memory graph from first principles: antisymmetric merging, fractal inheritance, deterministic retrieval, tenant isolation, and a traceable scoring path. A current local checkout run passed 1,009 tests, skipped 1, and emitted 500 warnings; the repository contains 200 test files and 39 SQL migrations.
