What I'm looking for

I'm looking for senior or staff frontend roles, or selective full-stack roles, that are remote.

At Breez, I delivered a multi-tenant organization admin center from requirements to production. I built Angular admin flows and NestJS REST APIs, integrated Keycloak with AD/LDAP, and developed an AI code-review pipeline in GitLab CI that reviews merge requests against team guidelines.

At Crystal Intelligence, I migrated a monolithic frontend to an Nx workspace and moved a blockchain transaction graph from SVG to Canvas, reducing frame time by about 60% while keeping it smooth at 10,000+ nodes. I’ve also developed Angular applications and shared UI libraries, and use Cursor and Claude in my development workflow.
