System Status: OPERATIONAL

// SYSTEM_IDENTITY

I am a solo 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 can move a system from architecture to production-ready implementation with clear contracts, validation, and operational reliability. I use tests, type checks, linting, security scans, and failure-path checks according to the needs and evidence of each project.

Based in Berlin. No traditional CS degree. Just production AI systems: FAIM-Native, NOESIS-Σ, Alcyoneus OS, AverQel, and ReveLith. 40+ FAIM engineering phases shipped solo, with 720 FAIM tests reported and 78 NOESIS-Σ test files documented across numerical correctness, cryptographic audit chains, memory validation, and governed runtime behavior. NOESIS-Σ is built as a code-first inference platform with a deterministic operator-split core, a three-tier cryptographic memory stack, an evidence-only DSL verifier, and Ed25519-signed receipts for every inference step. Alcyoneus OS applies the same discipline to state-graph agents, tools, memory, policies, identity, secrets, and observable execution. My background in leadership and operations (CMI Level 5) gave me something most engineers learn too late: that systems must be governed, not just functional. Currently studying BSc Business and Information Technology. Everything else I know, I proved by building it.

// GOVERNANCE_PROTOCOL

THE METHOD

Most developers write code, then test it. I design the Test & Governance Architecture first, then orchestrate the implementation.

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
▸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
▸Use project evidence: FAIM reports 720 passing tests; NOESIS-Σ documents 78 test files
▸Apply type, lint, and security checks where the repository supports them
▸Exercise retries, stalled streams, rejected actions, tenant isolation, tamper detection, and rollback paths
METHOD_STATUS::REPEATABLE

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

THE JOURNEY

Not a straight line. A deliberate pivot from leadership and operations into engineering, proved by what was built along the way.

FORMAL
PIVOT
SELF-DIRECTED
2021 to 2023FORMAL

Operations and HR foundation

Built a foundation in operations, people systems, accountability, and process improvement. That experience still shapes how I design ownership, permissions, workflows, and governance in software.

2022 to 2023FORMAL

Management and leadership studies

Studied strategic planning, decision frameworks, and operational governance. The work became a practical lens for building systems with clear contracts, validation gates, and auditable decisions.

Early 2024PIVOT

Deliberate pivot to engineering

Started systematic self-study in Python, data structures, graph theory, deterministic algorithms, FastAPI, PostgreSQL, and Docker. The transition was built through working systems rather than isolated exercises.

2024 to presentFORMALACTIVE

BSc Business and Information Technology

Continuing formal study while building production-oriented systems. It connects business context, information architecture, and software engineering in one track.

2024 to 2026SELF-DIRECTEDACTIVE

FAIM-Native: deterministic memory architecture

Designed a contradiction-aware memory graph from first principles: antisymmetric merging, fractal inheritance, deterministic retrieval, tenant isolation, and a fully auditable scoring path. The system grew through 40+ engineering phases and 720 passing tests.

2025 to presentSELF-DIRECTEDACTIVE

NOESIS-Σ: verifiable inference

Moved from memory infrastructure into high-assurance inference: a numerical Operator-Split Core governs state, a sandboxed DSL verifies claims against evidence, and signed receipts make inference inspectable. The model proposes; the system verifies.

2025 to 2026SELF-DIRECTEDACTIVE

Alcyoneus OS: governed agent runtime

Built an end-to-end agent operating system around state graphs, provider adapters, typed tools, memory, streaming, guardrails, policy, identity, secrets, sandboxes, observability, and evaluation. The focus is controlled execution, not chat alone.

2025 to 2026SELF-DIRECTEDACTIVE

AverQel: evidence-grounded workspace

Extended the systems work into a multi-tenant research backend: document ingestion, OCR and extraction, indexed retrieval, citation-backed answers, connected tools, governed automation, tenant isolation, and observable runtime boundaries.

2026SELF-DIRECTEDACTIVE

ReveLith: offline-first intelligent office suite

Applied the same systems thinking to desktop software: native document fidelity, local AI, Rust and WASM engines, typed agent workflows, sandboxed Electron boundaries, and release paths across Windows, macOS, and Linux.
