Work History
Responsible AI Engineer
Accenture
01.2025 - Current
- Engineered end-to-end Responsible AI frameworks with policy-as-code guardrails, automated lineage, and metric gates mapped to EU AI Act risk tiers and internal standards.
- Ran continuous audits across 140+ metrics (fairness, transparency, explainability, robustness, sustainability) with bias tests like disparate impact and specificity parity, producing mitigation plans and waivers.
- Built production LLM/RAG services with LangChain and LlamaIndex, adding evaluator agents for relevance, faithfulness, and toxicity; integrated IBM RAI/LIME for model transparency.
- Designed agentic A2A orchestration with safety boundaries, role-based capabilities, rollback strategies, and circuit-breakers; instrumented full telemetry using OpenTelemetry.
- Implemented secure MLOps on AWS (SageMaker, Bedrock, Lambda) with CI/CD, dataset versioning, and reproducible pipelines over PostgreSQL and Snowflake.
- Led red-team exercises (prompt injection, jailbreaks, data leakage) and codified decision logs and approval workflows to enforce accountable model releases.
- Built metric scorecards and dashboards for exec and audit consumption; drove continuous improvement of accuracy, fairness, and robustness SLAs.
- Mentored engineers and delivered org-wide training and workshops on Responsible AI and agentic patterns, establishing an internal center of excellence.
- Led the design and implementation of responsible AI frameworks, ensuring compliance with ethical standards and industry regulations.
- Collaborated with cross-functional teams to develop and refine AI models, enhancing system transparency and user trust.
- Conducted thorough risk assessments for AI initiatives, identifying potential biases and recommending corrective actions to mitigate impact.
- Developed training programs on responsible AI practices, empowering team members to integrate ethical considerations into their projects.
