What I'm looking for

I’m looking for a senior frontend role where I can build enterprise-grade React/Next.js products, optimize performance, and strengthen security for API integrations—while mentoring teams and supporting modern architecture and scalable releases.

I’m a Senior Frontend Engineer with 6+ years building enterprise SaaS and fintech applications, focused on modern frontend architecture and long-term maintainability.

I specialize in React, Next.js, and TypeScript, delivering reusable component libraries, performance optimization, and secure API integrations—often while modernizing legacy applications.

In my recent role, I developed OpenBanking (OBIE) applications, integrated REST APIs with Node.js/NestJS backends, and supported production rollouts while migrating MongoDB to PostgreSQL. I also implemented Keycloak-based authentication using OAuth2.0 and OpenID Connect (OIDC), and remediated SAST/VAPT findings using secure coding practices.

I enjoy collaborating across backend, QA, DevOps, and product teams, and I mentor junior developers through code reviews and architecture guidance. I also build user-facing experiences powered by third-party and AI services, including OpenAI API and HuggingFace.
