I'm Nitin Chavan, a full stack developer with 2+ years of production experience delivering responsive web applications with React.js, Redux, Node.js, Express.js and PostgreSQL. I turn business requirements into clean interfaces, reliable APIs and maintainable product workflows.
Business-focused screens, stable data flows, debugging, optimization and production support.
Engineering profile
Not a résumé.
A system map.
I work across React.js and Redux interfaces, Node.js and Express.js APIs, and PostgreSQL-backed business workflows. I build forms, reusable components, validations, API response handling, SQL queries, data-heavy screens and performance-minded UI. HRMS and payroll are strong production examples, and the same execution fits SaaS products, dashboards, admin panels, internal tools and customer-facing applications.
From user intent and UI states to APIs, data, error handling, observability and release validation.
Performance gains, fewer requests, stable releases and clear business outcomes—not decorative engineering.
Retries, validation, access control, transactions and predictable recovery are first-class product features.
Startup urgency when discovery matters; enterprise rigor when reliability and compliance matter.
