    Node.js API Engineering, Webhook Ingestion, and Integrations

    Syed Alijah Muhammad designs, builds, and debugs backend APIs using Node.js, Express, TypeScript, and modern database drivers. He specializes in creating consistent RESTful endpoints, bidirectional WebSocket connections, and resilient webhook handlers that gracefully survive upstream service timeouts and rate limits.

    Scope & Deliverables

    • ✓Custom REST API architecture with strict schema validation (Zod/Joi) and consistent JSON responses
    • ✓Bi-directional WebSocket and Server-Sent Event (SSE) infrastructure for live event streams
    • ✓Stripe payment gateway integration, subscription billing logic, and idempotent webhook handlers
    • ✓Secure user authentication: JWT sessions, OAuth2 social logins, and role-based access control
    • ✓API performance tuning, rate-limiting guards, and structured Winston/Pino production logging

    How the Architecture is Built

    Routing & Middleware Pipeline

    Express or Next.js route handlers equipped with rate limiting, CORS configuration, payload size guards, and centralized error catching.

    Service & Business Logic

    Decoupled domain services executing idempotent operations, third-party API calls with retry backoff, and database transactions.

    Database Interaction

    Optimized SQL queries via Prisma or raw pg driver, featuring connection pooling and indexed lookups to prevent request queueing.

    Demonstrated in Production

    Proof: Real-Time ISP Router Monitoring Dashboard (TR-069 + GenieACS)

    Engineered high-frequency API ingestion syncing router telemetry, WAN IP renewals, and device firmware updates across hardware fleets.

    Frequently Asked Questions

    How do you handle webhook failures from services like Stripe?

    I implement idempotent webhook handlers that store incoming event IDs in a deduplication cache or database table, acknowledge receipt with an immediate 200, and process the payload asynchronously.

    Can you connect my existing database to a new mobile or web frontend?

    Yes. I can build a clean, secure REST or GraphQL API layer in Node.js on top of your existing PostgreSQL or MongoDB database.

    What authentication methods do you implement?

    I implement stateless JWT tokens with HTTP-only refresh cookies, session-based auth with Redis, and integrations with Supabase Auth, Firebase Auth, or NextAuth.
