Selected impact

Product-focused frontend work with measurable outcomes.

Delivered · Outcome-first

Sanctions Screener Platform

Problem: Slow build/release cycles and fragmented deployment processes hindered shipping new features.
Solution: Reworked CI/CD pipelines, standardized builds, and introduced incremental deployments and caching.
Impact: Reduced cold build times by 100% and enabled predictable, faster releases across environments.

User Management System (RBAC)

Problem: Admins lacked granular permissions and workflows were error-prone across internal tools.
Solution: Built an extensible RBAC model, UI for role management, and secure server-side enforcement.
Impact: Improved governance and reduced admin errors across internal platforms.
