API & Backend Development for Websites and Web Applications
When a website needs more than static pages, I can connect the frontend to APIs, databases and backend workflows required for the project.
Reliable Server-Side Architecture & Data Flows
Modern websites frequently interact with external payment providers, messaging APIs, customer relationship management tools, and secure transactional databases.
REST API Architecture
Designing structured, documented REST APIs with versioning, input sanitization, rate limiting, and standard HTTP response status codes.
Third-Party Integrations
Seamless connectivity with external services: payment gateways (Razorpay, Stripe), SMS gateways, WhatsApp Business API, Mailgun, and Google Sheets.
Database Modeling & Queries
Relational and document database setups (PostgreSQL, MySQL, MongoDB, Redis) with index optimization, connection pooling, and automated backup routines.
Authentication & Permissions
Implementing JWT tokens, secure session storage, password hashing, and role-based access control (RBAC) to isolate sensitive customer records.
Webhooks & Async Tasks
Handling incoming webhook payloads for payment settlements, automated order confirmations, background data sync, and error retry queues.
CRUD & Admin Workflows
Backend controllers to handle Create, Read, Update, and Delete operations for products, lead submissions, member profiles, and business assets.

API & Backend Project Investment
Project pricing depends on scope, features, technology requirements and development timeline. Because integrating two webhooks differs substantially from architecting a multi-tenant API with automated database migrations, share your specific backend requirements to receive a project-specific estimate.
