Enterprise AI Focus

I build retrieval-grounded AI systems for document intelligence, multilingual search, biomedical workflows, and secure enterprise deployments.

Recent work combines multimodal RAG, vision-language models, hybrid retrieval, LangGraph-style orchestration, benchmark-driven evaluation, AWS reference architectures, and governance controls such as citations, audit logs, and human review.

I am open to enterprise AI roles where the work needs engineering discipline, measurable retrieval quality, and deployment-aware architecture.

Best repositories to review first: CaseLens-VLM, SOAS RAG Evaluation, and Breast Cancer Multimodal AI.

Target roles: Applied AI Engineer, Enterprise GenAI Engineer, RAG/LLM Engineer, AI Solutions Architect.


Selected Work With Metrics

Work Enterprise signal Evidence
CaseLens-VLM Multimodal document RAG over scanned pages with Qwen3-VL, hybrid retrieval, citations, audit controls, and AWS architecture mapping Recall@5 improved from 0.035 metadata-only to 0.708 with Qwen3-VL + BM25/MiniLM hybrid retrieval on 339 DocVQA questions
SOAS RAG Evaluation Bilingual RAG benchmark for culturally grounded English/Uzbek retrieval Uzbek retrieval recall improved from 39% to 98% through corpus supplementation; Cohen's d = 2.91
Breast Cancer Multimodal AI Biomedical multimodal foundation-model benchmarking across pathology, genomics, clinical features, and mammography CONCH V+C+G cross-attention C-index 0.609; Stage 1 AUROC 0.741; log-rank p = 0.005
DialogXR / sovereign deployment work Air-gapped enterprise AI deployment and multi-agent orchestration for secure environments LangGraph orchestration, Llama 3.1 8B via Ollama, Lenovo ThinkSystem SR630 V4 deployment pattern
NVIDIA DLI instruction Enterprise AI enablement and applied training delivery Delivered RAG and multimodal AI agent workshops for academic and engineering audiences

  • Experience with multilingual, multimodal, healthcare, education, and public-sector AI use cases
  • Practical deployment thinking across AWS, HPC, on-prem, and air-gapped environments
  • Governance-aware design: citations, human review, audit logs, limitations, and measurable quality checks

Open To

  • Senior Applied AI Engineer roles
  • Enterprise GenAI / RAG Engineer roles
  • AI Solutions Architect roles
  • Multimodal document intelligence and healthcare AI roles
  • Remote or hybrid opportunities across the UK, EU, UAE, and enterprise AI teams globally

Building evaluated AI systems for real enterprise constraints: retrieval quality, provenance, governance, and deployment.
