Finding what breaks.
Documenting why. Improving what comes next.

AI systems evaluator and quality-assurance professional with extensive experience directing AI-assisted workflows, testing outputs against defined rules, identifying failure modes, and driving evidence-based corrective action.

AI evaluation backed by systems operations and three decades of quality discipline.

Marcrooseler Sylla combines hands-on ownership of a multi-platform digital and AI-assisted ecosystem with 31 years of U.S. Army / Army Reserve service. His work centers on structured evaluation: testing instruction adherence, factual consistency, policy and safety behavior, edge cases, workflow failures, governance boundaries, and evidence of successful execution.

He directs multiple AI models and specialized executors across production-oriented workflows while maintaining explicit scopes, validation gates, evidence requirements, handoffs, and corrective actions.

Adversarial AI Evaluation

Challenge assumptions, prompts, instructions and system behavior to expose failure modes, inconsistent outputs and boundary violations before acceptance.

Quality & Validation

Define acceptance criteria, require evidence, document defects, separate claimed success from verified success, and validate corrective action.

AI Operations

Coordinate multiple LLMs and AI executors with explicit permissions, governance boundaries, structured handoffs and human approval gates.

Systems Governance

Build repeatable operational controls for knowledge, automation, deployment readiness, risk, maintenance, project status and decision continuity.

Cloud & Automation Oversight

Operational exposure to DigitalOcean, Cloudflare, Docker, PostgreSQL, n8n, Prometheus, Grafana, Loki and related infrastructure.

Asynchronous Sprint Execution

Self-directed, task-oriented work using concentrated sprints, checkpoints, evidence capture, structured reporting and acceptance testing.
