What I'm looking for

I’m interested in remote working, clean code, Domain Driven Design, and BDD or TDD with CI/CD. I’m tech agnostic and value strong fundamentals, with the ability to adapt quickly to any tech stack.

At Tulip, I maintain the product formerly known as Humankind, implement new features, and integrate new clients. I also handle small tasks and bug fixes for Tulip Outreach.

At Humankind, I contributed to building the product as a direct contractor, implementing features and fixing bugs while building frontend applications and backend services. I changed backend RPC calls to an Event Driven approach and presented software design approaches for product challenges.

Earlier, I worked as a Consultant at Mosano and WeDo Technologies on React map features, frontend products, and JavaScript-to-TypeScript and jQuery-to-React migrations. Since 2026, I’ve been developing an online store for a local business, including payment and shipment integrations, using SvelteKit.
