What I'm looking for

I'm looking for remote contract engagements, full- or part-time, where I can design, build, and operate SaaS platforms and AWS infrastructure end to end. I value written-first collaboration through clear specifications, tickets, and asynchronous updates.

I build and operate multi-tenant SaaS platforms on AWS, taking products from architecture and application development through infrastructure and production operations. At Pixalo, I built a production platform with paying customers as the sole engineer, including a 71-model PostgreSQL schema with database-level tenant isolation, native mobile apps, and billing workflows.

At Cloudox, I built the control plane for a managed cloud platform, automating customer orders into fully configured servers. I designed its 74-endpoint API, automated EC2 provisioning, AMI builds, backups, monitoring, subscriptions, transactional email, and an LLM-driven content pipeline.

Before my own products, I co-founded Webrazzi GmbH and led engineering for a decade, delivering and operating web and mobile platforms for clients. I'm available for remote contract work worldwide and work best through clear written specifications, tickets, and asynchronous updates.
