Cloud Architecture & API Integration Systems
High-throughput backend architectures, fault-tolerant REST APIs, webhook listeners, payment gateway orchestrations, and containerized cloud deployments that keep your services running 24/7.
Backends Designed for High Concurrency and Zero Failure
An application is only as good as the API and database that power it. We build hardened server systems that handle traffic spikes, ensure zero data loss during network splits, and protect against security threats.
RESTful & Real-Time APIs
Cleanly documented Node.js & Express API gateways with sub-50ms p95 latency, rate-limiting, CORS whitelisting, and strict request schema validation using Zod.
Payment & Webhook Reliability
Idempotent payment webhook consumers (Razorpay, Stripe, UPI) with cryptographic signature validation, replay attack protection, and automated reconciliation.
Docker & Cloud Deployment
Containerized microservices orchestrated via Docker and NGINX reverse proxies. Automated SSL renewal, zero-downtime rolling updates, and managed database backups.
Enterprise Integration Capabilities
WhatsApp Cloud API
Official Meta Cloud API webhook processing, template registration, and automated transactional delivery.
PostgreSQL & Redis
Relational schemas with index optimization, connection pooling with PgBouncer, and Redis pub/sub.
Cloud Hosting
Bespoke setup on AWS (EC2, S3, RDS), DigitalOcean, Hetzner, or private on-premise physical servers.
Security & Hardening
Helmet HTTP security headers, CORS isolation, rate limiting, and strict input sanitization.
