I build end-to-end React and full-stack features with UX and performance focus.
IndiaWhat I'm looking for
I’m a Software Engineer with hands-on ownership of 20+ React + TypeScript features across core product modules, delivering full-cycle changes from design and build to customer rollout.
I led greenfield UI surfaces like Launch Wizard, Environment Overview, Blueprint Graph & Table, and Release Details Modal, and I pair strong front-end craft with cross-stack delivery—shipping a Java / Spring Boot REST endpoint and optimizing MongoDB payloads from ~25 to 7 fields with JUnit/Mockito coverage.
I focus on reliability and usability: I fixed production routing edge cases, eliminated duplicate fetches by tightening React Query invalidations, standardized component patterns (FormDrawer + skeleton loaders), and hardened RBAC with global 401/503 auto-logout plus pre-expiry VCS-token re-auth.
Before this, I built and improved Angular experiences end-to-end, instrumented Mixpanel funnels to guide UX redesigns, and raised accessibility quality (including ARIA fixes and Lighthouse improvements). I also explore engineering beyond the web—building an Android expense tracker and a disease predictor that integrates a fine-tuned ResNet101V2 model via a Flask REST API.
