Experience
-
Senior Software Engineer @ UI Bakery.
–
As a core engineer on a low-code platform, I designed and delivered features from the Angular front-end to Java, Node.js, and MySQL services, helping grow it past 60,000 users to profitability:
- Built the front-end rendering engine that runs every application on the platform.
- Designed an extensible form-component architecture behind 59 of its 122 user-facing components.
- Shipped granular access control and unblocked enterprise adoption.
- Created an AI Figma-to-code workflow that eliminated most manual design work.
- Developed the multi-theme and white-labeling system, reducing bundle size from 18 MB to 12 MB.
- Reduced flaky Playwright tests by 70% and added render-performance and memory-leak checks to CI, catching regressions pre-merge rather than in post-release reports.
- Replaced manual releases with GitHub Actions pipelines, saving 30 minutes per release across weekly deploys.
- Introduced feature-flagged rollouts as the team standard for better control over feature partial release and fast rollback.
- Led all Angular major-version migrations, eliminating long-standing dependency vulnerabilities and unblocking the modern Angular toolchain.
