Django 5 + DRF, React 19 + Vite administration console ("command center") for VPN and networking product lines.
Full-stack ownership of a shared admin console spanning backend (serializers, models, views, migrations) and frontend, across three product lines.
Led a large-scale Redux to React Query migration: re-architected client-side data fetching across most of the application's feature areas, improving caching, loading-state handling, and reducing boilerplate.
Introduced a standardized data-table library to the codebase and drove years of follow-on work: bulk actions, sort/group/selection fixes, and TypeScript conversions of legacy table views.
Built the app's internationalization infrastructure end-to-end: designed the translation workflow and key-naming conventions, then migrated interpolation/pluralization to the ICU MessageFormat standard across every product area.
Cross-stack delivery: paired backend validation with frontend UI in the same change for features such as licensing-aware client states, licensing-based filtering, and network-routing validation.
PostgreSQL schema design: added referential-integrity and uniqueness constraints, migrated a column to a native network-address type, and redesigned a foreign-key relationship to gracefully fail over to a fallback record instead of leaving orphaned rows.
Introduced Zod schema validation, later upgraded from v3 to v4, and rewrote several forms and state-management logic around React Hook Form + Zod.
Kept the frontend stack current: upgraded React 17 → 18 → 19 along with TypeScript and Redux dependencies.
Introduced Vite and Vitest, and added unit and component tests to the frontend.
Migrated the frontend/CI toolchain from npm/yarn to pnpm, including CI build images, for faster and more reproducible builds.
Diagnosed and fixed a non-deterministic ordering bug in a microservice's list API (map iteration order plus an incorrect SQL join type), correcting both the handler and the underlying query.
Profiled and optimized a slow data-serialization endpoint as part of a broader performance-tuning effort.
