What I'm looking for

I'm looking to build AI-powered and full-stack products end-to-end, turning ambiguous ideas into reliable, monitored systems with meaningful user impact.

At HolyWater, I build AI creative production systems and a generative-AI studio for performance marketing. I own the platform end-to-end, from queue-driven worker fleets and ML-provider routing to idempotent billing, monitoring, and operational dashboards.

I built a serverless generation platform on GCP Cloud Run and Cloud Tasks, with reconciliation workflows, atomic credit refunds, real-time progress, and distributed tracing across web, API, queues, workers, providers, and storage. I also shipped an LLM storyboard agent, marketing automation flows, and a WASM-backed browser reel editor.

For HolyWater's internal creative-tools platform, I built automation producing 500–750 video creatives daily and an AI localisation pipeline supporting 8+ locales. Previously at Maprehend, I led frontend work on manufacturing configurators, built company-wide OAuth2 and PKCE SSO, and delivered Laravel, Vue, Nuxt, Three.js, and Python systems.

I'm a hackathon winner who turns vague ideas into shipped, monitored products.
