Technical Skills
Work Experience
- Architected and developed the core multi-role marketplace backend using Node.js and Express.js, structuring separate route modules and middleware layers for freelancer, client, startup, and investor user types.
- Designed MongoDB collections and schema relationships to support project listings, user profiles, subscription plans, and transaction histories, enabling efficient querying across role-specific dashboards.
- Implemented JWT-based authentication and role-based access control, ensuring each user type accessed only the dashboards, project data, and admin-panel features permitted by their assigned role.
- Integrated the Easebuzz payment gateway into the subscription and payment workflow, handling payment initiation, callback verification, and order-status updates within the backend service layer.
- Built reusable React.js components and role-specific dashboard views, connecting each UI module to its corresponding REST API endpoint for real-time data display and form submissions.
- Diagnosed and resolved cross-module application defects — covering frontend state inconsistencies, API error handling gaps, and database query performance — reducing recurring issue reports across the platform.
- Developed responsive property-listing and management pages using HTML5 and CSS3, ensuring consistent layout and usability across desktop and mobile viewports.
- Built backend property workflow logic using Python and Flask, covering property creation, status updates, search filtering, and agent-assignment endpoints consumed by the frontend.
- Integrated third-party APIs into the Flask backend to support property data enrichment and notification workflows, writing request-handling and error-response logic for each integration.
- Maintained and debugged SQL database queries underpinning property records, user accounts, and agent assignments, resolving data-inconsistency issues identified during QA cycles.
- Backed application deployment activities, coordinating environment configuration and verifying API connectivity between the Flask backend and the hosted frontend after each release.
- Refactored existing JavaScript frontend interactions to eliminate redundant DOM operations, improving page-load responsiveness across high-traffic property-search views.
