You will get a secure REST API and backend using Node.js or Python

Project details
Get a secure, documented REST API and backend for your web application, mobile app, SaaS product, or third-party integration.
I develop backend services using Node.js or Python with structured endpoints, validation, authentication, database integration, error handling, and clear documentation. Depending on the selected tier, the API can support CRUD operations, user roles, file handling, external APIs, background tasks, webhooks, notifications, and deployment.
You will receive tested source code, environment configuration guidance, endpoint documentation, database models, and handover notes. The implementation will be organized for maintainability so another developer can understand and extend it.
This service requires a defined data model and endpoint scope. Complex legacy migrations, undocumented third-party systems, high-scale infrastructure, custom machine-learning training, and ongoing DevOps support are not included unless purchased separately.

My experience includes developing an AI resume builder API using Node.js, creating an augmented reality shopping experience, building multi-vendor marketplace functionality, and delivering applications with real-time data visualization.
I can support your product throughout the complete development lifecycle:

My core technologies include React, Node.js, Python and API-based architectures. I focus on building maintainable applications with clear user flows, reliable backend functionality and interfaces designed around real business requirements.
I help clients in fintech, real estate, e-commerce, and health/fitness launch and scale products. Typical engagements include:
- Building web and mobile apps from scratch (React, React Native, Vue, Angular)
- Backend architecture and APIs in Laravel, Django, or Flask
- Integrating payments and third-party services (Stripe, PayPal, Twilio, DocuSign, Google Maps)
- Adding AI features like chatbots, content generation, and recommendation systems
- Post-launch maintenance, QA, and ongoing support with Agile workflows (Scrum/Kanban, JIRA, ClickUp)
You can expect clear communication, practical technical recommendations and ownership of the work from planning through development and deployment.
I've completed 16 projects on Upwork with a perfect 5.0 rating. My work spans legal consultation apps, multi-vendor marketplaces, real estate platforms, and food delivery services, several of which are featured in my portfolio below.
