What I'm looking for

I’m looking for an environment where I can build scalable backend systems and REST APIs, focusing on backend architecture and performance. I’m available for immediate joining and want to grow with strong developer tooling and reliability-minded engineering teams.

I’m a Backend Engineer experienced in building scalable systems and REST APIs using Node.js, TypeScript, JavaScript, and Python, with active open source contributions and a strong focus on backend architecture, performance, and developer tools.

In my Virtual Internships Partner role (Backend Focus), I redesigned a backend data model for multi-system integrations, eliminating duplicate records and preventing recurring synchronization failures affecting 25K+ partner accounts. I also reduced average query latency by 60% by improving filtering logic and database indexing, and I designed and implemented an in-house backend replacement for an external third-party service—owning system design, schema modeling, API contracts, and data migrations to improve reliability and cut ongoing third-party costs.

I continue to build end-to-end systems—like my Next.js mock-interview platform using streaming avatars, LLM-based evaluation, and a RAG pipeline—and I’m available for immediate joining.
