    European Air-Quality Evidence Agent

    Individual work by Ahmed

    Problem and system approach

    An agentic evidence system integrating MCP tools, retrieval, evidence validation, security controls and evaluation.

    Implementation context and limits

    The system connects MCP tool integration with retrieval and evidence grounding for European air-quality research.

    Its verified scope includes evidence validation, security controls and evaluation without an unverified numeric-results claim.

    Verified evidence

    • Agent and retrieval integration: MCP tool integration connects retrieval with evidence grounding.

      Method: Implementation-scope review.

    • Evidence controls: Evidence validation and security controls are part of the reviewed implementation.

      Method: Implementation-scope review.

    • Evaluation boundary: Evaluation is in scope; no quantitative performance result is claimed.

      Method: Implementation-scope review; no numeric outcome is claimed.

  2. Published case study

    FinRL–DeepSeek Research Extension

    Individual work by Ahmed

    Problem and system approach

    Extended FinRL–DeepSeek with a confidence-weighted, turbulence-aware signal layer for constrained PPO trading and evaluated the system through deterministic and 10-seed stochastic backtests.

    Implementation context and limits

    Individual Phase 1 extension and sole report authorship, with explicit attribution to the upstream FinRL–DeepSeek project.

    Results are historical backtests, not live-trading performance or investment advice; upstream attribution and documented evaluation limitations must remain visible.

    Verified evidence

    • Deterministic EP90 annual return: 17.12%

      Method: Deterministic EP90 historical backtest.

    • Ten-seed stochastic mean annual return: 16.843% ± 3.517%

      Method: Ten-seed stochastic historical backtest; mean ± standard deviation.

    • Ten-seed stochastic mean maximum drawdown: −25.921% ± 1.671%

      Method: Ten-seed stochastic historical backtest; mean ± standard deviation.

    • Deterministic total return: 119.86%

      Method: Deterministic EP90 historical backtest.

    • Deterministic Sharpe ratio: 0.750

      Method: Deterministic EP90 historical backtest.

    • Ten-seed stochastic mean Sharpe ratio: 0.878 ± 0.173

      Method: Ten-seed stochastic historical backtest; mean ± standard deviation.

    MetaMind Responsible AI Learning Companion

    Individual work by Ahmed

    Problem and system approach

    A multi-agent Socratic tutoring system with persistent learner state, learning history, adaptive guidance and user-triggered fairness-audit functionality.

    Implementation context and limits

    Verified implementation includes a planner agent, Socratic tutor, learning-signal extractor, fairness reviewer, controller and state transitions, SQLite persistence, a CLI and a Streamlit interface.

    Fairness audits are user-triggered; no learning-effectiveness or fairness-outcome evaluation has been completed.

    Verified evidence

    • Multi-agent architecture: Planner agent; Socratic tutor; learning-signal extractor; fairness reviewer; controller and state transitions.

      Method: Implementation-scope review.

    • Persistent learner state: SQLite persistence supports learner state and learning history across sessions.

      Method: Implementation-scope review of the CLI and Streamlit interfaces.

    • Responsible-AI boundary: Fairness audits are user-triggered; learning effectiveness and fairness outcomes remain not evaluated.

      Method: Implementation-scope review; no learning-effectiveness or fairness-outcome result is claimed.
