Professional Experience

My professional journey across various companies, roles, and projects in software engineering, AI/ML, and technology innovation.

Swinburne University of Technology

Hawthorn, Australia

Researcher

August 2025 - February 2026

Led research team of 5, funded by Swinburne to build a multi-agent system with domain-specialist agents (diagnostics, pharmacology, triage) coordinated by a reasoning agentic orchestrator MCP:

Key Deliveries:
  • Boosted diagnostic accuracy & safety for LLM agents on 500k+ curated SFT & synthetic cases, using Knowledge Distillation, LoRA/QLoRA (GRPO reasoning), SLERP merging technique, and augmentation (QAC paraphrasing/chunking, self-consistency, counterfactuals, backtranslation).
  • Built agentic RAG (Tree + HNSW + FAISS) over EMR/EHR + PubMed with retrieval safety rails, real-time update, and citations to mitigate hallucination. Finetuned 300M embedding and reranking model on over 5M curated.
  • Trained biomedical reranker model on 8M selective medical corpus. Integrated in MAC (multi-agent conversation) architecture to boost IR rate.
  • Established strict evaluation: MedMCQA / PubMedQA / MedQuAD (86% BertScore) benchmarking, semantic similarity audits with biomedical embeddings, early-stopping LR scheduling; trained reproducibly on HPC.

Mizco

Perth, WA, Australia

AI Engineer

November 2025 - March 2026

Led a self-sourced team (contracted via Teqar) to build a client–server, plugin-style multi-agent assistant that ingests PDFs/DOCX/XLSX, normalizes to Markdown and JSON objects, performs semantic chunking + RAG, and auto-completes technical outcome docs with grounded, auditable facts.

Key Deliveries:
  • Cut manual document assembly from ~80 hours to minutes, while maintaining source traceability, accuracy and customisability.
  • Architected a privacy-first stack: Llama-3.1 (orchestrator), olmOCR (parsing), EmbeddingGemma (embeddings), FAISS/HNSW (vector search) in multi-layered tree, FastAPI on private on-prem runtime.
  • Delivered agentic tooling to CRUD documents on staff request (update tables, fill cells, rewrite sections) and incremental re-ingest on file changes; achieved ≥90% autofill coverage with <2% error in audits.
