Work Experience
Haast
2023 - Present
Sydney, Australia - Remote
Joined as the founding frontend engineer at Pre-Seed for a B2B AI-native marketing & legal compliance platform used by enterprises. Built and owned the majority of the frontend for the core product. Scaled through Seed (Airtree $6M) and into Series A during a period of rapid growth (4.5x YoY revenue growth), now used by Fortune 500 companies.
- Built and scaled core product systems (workflows, reviews, asset management, rule pipelines) and document workflows (PDF comparison, annotations, commenting) used in enterprise compliance workflows, contributing to 80% reduction in manual review effort and 2-3x faster time-to-market
- Led frontend foundation: migrated and optimized build system from Rollup → Vite reducing local dev build times from 30s to 500ms (50x faster, instant HMR), and upgraded Svelte v3 → v4 (+ contributions toward v5) and introduced Tailwind + DaisyUI
- Delivered audit-ready review and collaboration UX (annotations, commenting, workflow states) providing complete audit trails and a single source of truth for regulated enterprise approvals
- Stabilized complex state-heavy workflows and resolved production reactivity issues, improving reliability and scalability of critical user flows
- Established engineering standards (TypeScript, linting, CI, pre-commit) and contributed to in-house design system and frontend scalability across the product

Joined as an early full-stack engineer and built a 0→1 AI comic creation platform, owning end-to-end development and working closely with the founder to ship the MVP from concept to production.
- Developed key features including authentication, a custom drag-and-drop editor, AI scene and character generation, character chat, and creator monetization flows (payments + payouts via Stripe)
- Integrated LLM and image generation workflows (LangChain, GPT-3.5, fine-tuned Stable Diffusion) to enable AI-driven content creation
- Built full-stack architecture using SvelteKit, TypeScript, MongoDB + Prisma, and GCP for media storage, evolving backend from Firebase to a more scalable setup
