Project What you can explore Current boundary
Biomedical Hybrid IR Compare lexical, dense, hybrid, and reranked biomedical search on NFCorpus. Results · Reproduce Recorded six-method study; portal displays exported results rather than live model inference.
DriftCVE-NLP Investigate vulnerability classification and retrieval as language changes over time. Dataset · Reproduce Recorded chronological experiments; live inference is pending.
Drift-Robust TinyML Study electronic-nose sensor drift, compact models, and resource-aware explanations. Protocol · Reproduce Host-side experiments and numerical equivalence are documented; physical MCU validation remains blocked.

Build with me

I welcome developers, researchers, and people who can help test practical workflows.

Interested in… A useful way to participate Where to begin
Biomedical search Reproduce a baseline, investigate a failed query, or improve setup instructions. IR issues
Cybersecurity NLP Review preprocessing, reproduce temporal evaluation, or report dataset problems. DriftCVE issues
Embedded ML Review export workflows or discuss real-board validation and instrumentation. TinyML issues
Interactive learning Try a lesson or challenge and report its steps, expected behavior, and actual outcome. JavaScript learning issues

Read the project's setup and contribution guidance, check existing issues, and propose a focused change before beginning a large implementation. Reproduction reports are welcome even when your results differ.

For research collaboration or engineering opportunities, email me.

How I work

  • Reproducible experiments: explicit data provenance, versioned configurations, and saved artifacts.
  • Careful evaluation: report measured findings, limitations, and pending work with their supporting evidence.
  • Practical delivery: documented setup, automated checks, and complete user workflows.

Research background, full project evidence, and technical toolkit

About

I am pursuing a PhD in Computer Engineering at Florida Atlantic University, in the Department of Electrical Engineering and Computer Science. I hold an MS in Computer Science with an AI/ML focus from Westcliff University.

My research connects distribution shift, explainability, and resource-aware machine learning. I build reproducible experiment pipelines and interfaces that make their evidence accessible. My applied engineering work spans AI business automation, web and mobile applications, and software testing.

Selected research

Project Research question and implementation Current evidence
Drift-Robust TinyML How do compact electronic-nose models and explanations behave under chronological sensor drift? UCI data, frozen evaluation protocols, XAI, and embedded equivalence checks. Recorded baseline, drift, and host-side XAI experiments; fused FP32 inference and local-XAI equivalence. Physical MCU latency, memory, and energy validation remain blocked.
DriftCVE-NLP How does vulnerability language change over time, and what happens to CVE classification and retrieval? NVD ingestion, chronological splits, lexical and embedding models, provenance, and result export. Versioned dataset and recorded experiments with confidence intervals and per-example predictions. Live inference remains pending.
Biomedical Hybrid IR When do lexical search, dense retrieval, hybrid fusion, and reranking help biomedical search? TF-IDF, BM25, BGE, MedCPT, reciprocal rank fusion, and cross-encoder evaluation on NFCorpus. Six evaluated methods, result tables, statistical comparisons, query-level error analysis, and reproducibility documentation. A completed course study with a working manuscript.
DriftGuard-IoT Can leakage-safe intrusion detection remain useful across IoT/IIoT datasets and changing traffic? Baseline reproduction, drift monitoring, adaptation, and resource evaluation. Development runs and tested evaluation utilities; real-data research campaign remains blocked. Synthetic runs are non-reportable.
Customer Behavior Prediction — Part 2 How should financial prediction be evaluated beyond static accuracy? Temporal stability, calibration, explanation stability, and cost-sensitive decisions. Research protocol, preflight/provenance runner, and evaluation utilities. Empirical manuscript results await benchmark acquisition and execution.

Portals communicate experiment artifacts and project status; deployment alone does not establish model validity or hardware performance.

Applied AI and product engineering

Project Engineering focus Stage
Lead.AI Product Platform Lead capture and business automation across FastAPI, React, Flutter, and Firebase. MVP; production-readiness work continues.
Lead.AI Fraud Benchmark Reproducible tabular training, held-out evaluation, deterministic reasoning tasks, artifact checksums, and controlled publishing workflows. Controlled synthetic benchmark; results do not establish real-world fraud performance.
SitaRam Multilingual Flutter application with corpus provenance, content validation, and evidence-grounded assistance. Application and release workflows; source coverage remains incomplete.
Working Woman Report Next.js editorial platform connecting a canonical weekly story with publishing, archive, and distribution workflows. Rebuild with content schemas and provider adapter foundations.

Additional operational prototypes: FleetDesk and DailyOps are documented in the portfolio roadmaps. Their source repositories currently require collaborator access.

Additional work: payment management, AI companion interfaces, construction lead management, and JavaScript learning tools.

How I work

  • Reproducibility: versioned configurations, explicit data provenance, chronological splits, and saved result artifacts.
  • Honest evaluation: distinguish measured findings, synthetic demonstrations, pending experiments, and blocked hardware work.
  • Useful explanations: assess explanation fidelity, stability, and computational cost alongside predictive performance.
  • Reliable delivery: automated tests, validation gates, documented setup, and clear application boundaries.
