Balvinder Parwar

I’m a full-stack software engineer with 2+ years of experience building data-intensive, multi-tenant web applications. I focus on access control and security-hardened architecture, while keeping features production-ready end to end.

My core stack is React.js, TypeScript, and Python/Flask. I’ve worked with Apache Superset, ECharts.js, and AG Grid to deliver analytics platforms and data experiences that are practical for real users.

In my role, I’ve owned critical security and platform capabilities—implementing JWT verification, OAuth/PKCE login flows, and migrating session storage to secure HTTP-only cookies. I also automated Row Level Security (RLS) across 100+ datasets and built tenant onboarding/admin functionality with team-scoped data isolation.

I’m comfortable across the full stack, from clean, reusable UI components and API integration to backend production hardening and data pipeline optimization. I enjoy replacing hardcoded configurations with dynamic, database-driven systems that reduce operational overhead and errors.
