AI integration & prototyping
From agent design and RAG pipelines to realtime voice experiences. I've built production systems on Claude, OpenAI, and the Twilio/WebRTC stack — the hard kind that actually work in front of real users.
I'm Isaak. A Melbourne-based full-stack and AI consultant. I help founders and product teams go from first prototype to production — particularly on the messy, AI-native edges where most engineers stall out.

Shipping end-to-end. React on the front, Node or Python on the back, Postgres and Supabase in between. Opinionated about simplicity, descriptive code, and systems that don't fall over at 2 a.m.
For founders without an in-house technical lead. Architecture reviews, hiring, pragmatic tech-stack decisions, and the kind of direct feedback that stops you burning a quarter on the wrong thing.
Fixed-scope engagements to get a working product in front of real users. Ideal for pre-seed and seed founders who need velocity without sacrificing engineering fundamentals.
AI-powered care navigation and triage for Australian health providers.
A multi-channel AI assistant that meets people where they already are — web, WhatsApp, SMS, and voice — and routes them to the right care. Built on Claude, the OpenAI Realtime API, Twilio, and Supabase. Designed to work within the reality of Australian privacy law (Privacy Act, APPs, NDB, Victorian HRA).
A network and platform for independent traders.
Co-founded CTN to build community infrastructure and tooling for independent traders. Hands-on across product, engineering, and go-to-market.
Early-stage AI startup — product engineering.
Contributed to product engineering at an early-stage European AI company. Worked across the stack on features touching AI, infrastructure, and user-facing experiences.
A bowtie funnel for sales and revenue optimization.
I designed and built the "bowtie" chart — a funnel-based visualization that pulled raw data from connectors and transformers into a single interactive view for sales conversion and revenue optimization. It sat at the core of the Jaxx analytics product, translating messy customer data into something an operator could actually act on.
I've spent the last seven years quietly getting good at the unglamorous part of software — making things actually work. First teaching myself the fundamentals, then shipping at AI startups in Europe and the US, and now building my own company from Melbourne.
The work I'm best at sits at the intersection of AI and real product: systems that touch users, handle money or health information, and need to behave reliably when the demo is over. I care about simple solutions, descriptive code, and the kind of engineering that holds up when someone else inherits it.
If you're a founder, operator, or engineering lead looking for someone to help you ship a hard thing — not just talk about it — we should probably talk.
Tell me what you're working on. If I'm the right fit, we'll figure out the shape of an engagement. If I'm not, I'll tell you who is.
