What I'm looking for

I’m looking to build production-grade web apps end-to-end in an async remote environment. I want ownership (auth, APIs, DB, and frontend) and a team that ships—so I can deliver without hand-holding.

I build production-grade web apps end-to-end — from PostgreSQL schemas to deployed Next.js frontends. At Ritswa, I shipped 6 full-stack products in a team of 6, including billing and inventory systems that are live and in active business use.

I work best in async remote environments and I don't need hand-holding to deliver. I’ve owned full auth flows across multi-role systems, built and maintained 30+ REST APIs with JWT auth and RBAC, and reduced average API response time by 30%+ through query optimization and caching.
