What I'm looking for

I work best with full ownership of a system and a problem that is not yet fully defined.

At Robosim.AI, I was the sole full-stack engineer on the web platform, working across Next.js, FastAPI, and PostgreSQL. I built an interactive 3D warehouse and simulation editor, along with AI features that included a warehouse-design agent and voice commands with validation and safety checks.

I also automated AWS infrastructure with Terraform and Docker and set up GitLab CI/CD. I compared monolith migration options with the CTO, and phased extraction became the migration plan.

At D-Talk, I built a real-time creator and customization editor and took over infrastructure on Azure. In freelance work, I take client products from requirements to production; I also founded BeadCraft Studio, a bracelet configurator now being packaged as a Shopify app.
