I build production AI agent systems and workflow automation — using n8n, Make, LangChain, and multi-agent orchestration frameworks (MCP, LangGraph). I've deployed RAG pipelines, voice AI integrations (Vapi), and API-connected automation that replace manual business processes at scale. I help companies build cloud infrastructure and AI systems that actually work in production. Background: 15 years in platform engineering, including 4+ years as Director of Engineering at Nike where I architected infrastructure handling millions of requests. More recently: led platform engineering at Canva, built custom transformers for defense applications (early illness detection), and I'm currently building an AI-powered healthcare platform. What I do: → Cloud architecture (AWS, Azure, Kubernetes, Terraform) → AI/ML implementation — LLMs, custom models, MLOps pipelines → Platform engineering — CI/CD, developer experience, self-service tooling → Technical leadership — team building, architecture decisions, due diligence Recent work: - Built multi-model AI pipeline (GPT-4V, Claude, DeepSeek) for healthcare document processing - Developed custom transformer architecture for warfighter early illness detection - Designed CI/CD systems at Nike still used by hundreds of engineers globally I work async, communicate clearly, and deliver documentation you can actually use. If you need senior technical work done right, let's talk.

AI / Agentic Engineer specialising in production LLM systems: agents, RAG, and the engineering that makes them reliable. I'm a Software & AI Engineer with 3+ years' professional experience and a Master of Artificial Intelligence from the University of Technology Sydney (Dean's List, GPA 6.69/7), plus AWS Certified Machine Learning Engineer - Associate. My main project, NimbusQuant (live at nimbusquant.tech), is a six-agent LangGraph system doing retrieval-augmented generation over financial filings, with a provider abstraction across OpenAI, Anthropic, Google and local models, number-grounding checks so it cannot invent figures, and a 61-test suite. I built and deployed it end to end on AWS (ECS + Fargate + S3/CloudFront) with GitHub Actions CI/CD. What I can do for you: - Agentic systems & LLM apps: LangChain/LangGraph, tool-calling, multi-agent orchestration, MCP - RAG & document intelligence: vector search (pgvector/Pinecone), chunking, grounding, evaluation - Python backends & APIs: FastAPI/Flask, PostgreSQL, Docker, AWS, CI/CD - Making AI reliable: evals, guardrails, and monitoring, so it works on real data, not just demos Also have background in computer vision (YOLOv8, OpenCV) and robotics/control systems (warehouse AGV/AMR software). I ship things that actually work, and communicate clearly in English (PTE 90) and Japanese (JLPT N2).

You've been told to "use AI." Nobody has told you where it actually fits in YOUR business. That's what I do. I find the manual work in your operations that should be replaced by AI - and the work that shouldn't - then I build the systems that make it real. I'm not a no-code automator who picked up the stack last year. I'm a senior software engineer with 15+ years shipping production systems at multi-billion-dollar companies and acquired startups. That depth matters when you're integrating AI into a real business, because most projects look simple in a demo and get complex fast. And then break because they haven't been thought out properly. ━━━━━━━━━━ 𝗥𝗘𝗖𝗘𝗡𝗧 𝗪𝗜𝗡𝗦 ✓ Saved an 8-figure Australian eCommerce brand $55K+/year by automating SEO product page generation from messy Shopify data ✓ Built a cold email system generating $1M+/year in pipeline for a SaaS company — 7 to 10 sales calls booked weekly on autopilot ✓ Built a lead-gen system for a recruitment firm that identifies 300+ high-value prospects monthly via hiring signals (funding rounds, expansions, transformations) — before competitors see them ✓ Reclaimed 20+ hours/month for a 7-figure business brokerage with a LinkedIn content system ✓ Found 10,000+ actively hiring companies for a recruitment client in week one ━━━━━━━━━━ 𝗠𝗬 𝗕𝗔𝗖𝗞𝗚𝗥𝗢𝗨𝗡𝗗 I'm not a consultant who reads about AI. I actually build the things. → Master's in Computer Science → 15+ years engineering across mobile, web, automation, and AI → Led mobile development teams at Tabcorp (launched Keno app generating $100K+/month) and AGL (Australia's largest energy company) → Worked at Pie - a Singapore startup later acquired by Google I build with Claude, Codex, n8n, Supabase, Python, Node, React - and whatever else fits the problem. I'll tell you when no-code is the right answer and when you actually need something custom. Most "AI experts" can only sell you the tool they know. I'll tell you the truth. ━━━━━━━━━━ 𝗪𝗛𝗬 𝗧𝗛𝗜𝗦 𝗠𝗔𝗧𝗧𝗘𝗥𝗦 𝗥𝗜𝗚𝗛𝗧 𝗡𝗢𝗪 The cost of building custom software has dropped dramatically in the last 18 months. AI didn't just give us ChatGPT. It gave senior engineers the ability to ship in days what used to take months. That changes things, a lot. You can now own custom AI systems built for YOUR data, YOUR workflows, YOUR team. And all for less than what you're paying in annual SaaS subscriptions to tools that don't even talk to each other. The SaaS-bloat era is ending. Custom is finally cheaper than off-the-shelf. ━━━━━━━━━━ 𝗧𝗛𝗘 𝗔𝗜 𝗜𝗡𝗧𝗘𝗚𝗥𝗔𝗧𝗜𝗢𝗡 𝗔𝗨𝗗𝗜𝗧 If you don't know where AI fits in your business, this is where we start. What you get: ✅ Full operational audit (15–20 page document mapping every manual workflow, bottleneck, and data silo) ✅ AI & Automation Opportunity Map — what's worth automating, what's not, what to build first ✅ ROI projection + savings report — real numbers, not vibes ✅ Priority matrix — what to fix first, ranked by impact ✅ One Claude AI agent or automation deployed in week 1 ✅ 30-minute strategy walkthrough call Investment: $2,500. Yours to keep regardless. 🛡 Guarantee: if I don't find at least $2,500/month in operational savings, you pay nothing. Full refund. You keep every deliverable. The audit takes 2–3 weeks. I do the heavy lifting. I need about 5–10 hours of your team's time across interviews and a tool walkthrough. ━━━━━━━━━━ 𝗧𝗛𝗘 𝗠𝗔𝗧𝗛 A 15-person team losing 8 hours per week per person to manual processes (copy-pasting between tools, hunting for data, re-entering things) at a $50/hr blended rate = $312,000/year in waste. The audit costs $2,500. That's less than three days of what you're already losing. ━━━━━━━━━━ 𝗜𝗦 𝗧𝗛𝗜𝗦 𝗙𝗢𝗥 𝗬𝗢𝗨? This works best if you have: → 10+ employees → $500K+ revenue → A clear sense your team is buried in manual work that should already be automated → A decision-maker ready to act, not browse This is NOT for you if: ✗ You want someone to bolt a chatbot onto your website ✗ You're shopping for the cheapest n8n freelancer ✗ You think AI is magic that doesn't need integration into real systems ━━━━━━━━━━ 𝗦𝗧𝗔𝗖𝗞 𝗜 𝗕𝗨𝗜𝗟𝗗 𝗪𝗜𝗧𝗛 Claude, OpenAI, n8n, Supabase, Airtable, Python, Node, React, Shopify API, Apify, Firecrawl, Instantly, Hunter. And whatever else fits the problem. ━━━━━━━━━━ 𝗡𝗘𝗫𝗧 𝗦𝗧𝗘𝗣 📩 Send me a message with one line: what does your team spend the most manual time on right now? I'll tell you within 24 hours whether the audit makes sense. And if it doesn't, I'll tell you that too. No pitch. No pressure.
