What I'm looking for

I seek backend or full-stack roles where I can build scalable, observable systems, work with multi-tenant architectures and data pipelines, and grow toward platform or SRE responsibilities in a collaborative, testing-driven team.

I am a backend-focused full-stack developer with hands-on experience building scalable systems, workflow engines, and BI solutions. I deliver production-ready REST APIs, modular services, and multi-tenant architectures using Node.js, NestJS, PostgreSQL, Redis, and TypeScript.

During a Backend Development internship I developed core modules for a Workflow Execution Engine, implemented observability with Pino and OpenTelemetry, optimized queries and caching with PostgreSQL and Redis, and achieved 90%+ unit-test coverage across core modules. I’ve also built full-stack projects including a multi-tenant Consumer Management System, a Retail BI Analytics pipeline with ML-driven segmentation, and an AI-enabled PDF Review Dashboard.

I lead small teams in hackathons and student projects, practice clean architecture and coverage-driven development, and focus on measurable performance improvements, maintainability, and secure multi-tenant designs.
