What I'm looking for

I'm looking to build production web applications where I can contribute across React, Node.js, Python, APIs, databases, authentication, and async systems while learning from experienced engineers.

I'm building a large role-based enterprise CRM at PanScience Innovation, delivering its Node.js/Express backend and React/Redux frontend end-to-end.

I design Swagger-documented REST APIs with Prisma and PostgreSQL, JWT and Azure AD authentication, and fine-grained role-based access control. I also implement BullMQ/Redis async workers, bulk Excel pipelines, and Jest unit and integration tests maintained at 95%+ coverage.

Previously, I shipped React components for Skymet Weather Services' internal dashboard using live meteorological station feeds. At Fonada, I traced and fixed admin-panel issues across React, Express, and database layers while working in Agile sprints.

I've independently built role-based applications including a Clinic Management System and an AI Resume Screener with FastAPI, PostgreSQL, Celery workers, and OpenAI API integration.
