Backend & APIs
Secure REST and GraphQL APIs, robust database architectures, and cloud integrations.
Overview & Engineering Approach
A great frontend requires an unshakeable backend. I build high-concurrency, secure server-side systems and APIs that connect your web apps, mobile apps, and third-party services with low latency, high throughput, and rock-solid data integrity.
What I Deliver & Build
RESTful & GraphQL API Architecture
Clean, self-documenting API endpoints designed with versioning, rate limiting, and strict input validation.
Database Design & Optimization
Schema normalization, indexing strategies, connection pooling, and caching with MongoDB and PostgreSQL.
Authentication & Security Hardening
Secure token-based JWT authentication, OAuth integrations, data encryption at rest and in transit, and CORS policy enforcement.
Third-Party Webhook & Service Integrations
Flawless integrations with Stripe, Razorpay, WhatsApp Business API, Twilio, SendGrid, and OpenAI APIs.
Technology Stack & Tools
Engineering Workflow
API Contract & Specification
Documenting endpoints, payload schemas, and authentication flows.
Data Layer & Indexing
Crafting normalized tables/collections and indexing heavy query paths.
Security & Middleware
Setting up input validation, rate limiting, error logging, and encryption.
Benchmarking & Monitoring
Stress testing, load latency audits, CI/CD pipeline automation, and uptime monitoring.
Frequently Asked Questions
Can you build backends capable of serving both Web and Mobile apps?
Yes, that is my specialty. A single centralized Node.js/Express or Next.js API layer powers web clients, mobile Flutter clients, and external webhooks simultaneously.
Do you provide API documentation for existing teams?
Yes. Every project includes comprehensive Postman collections, OpenAPI/Swagger specifications, and environment setup guidelines.
