Database & Backend Systems

Backend infrastructure that scales to millions — engineered for reliability.

We design and build custom REST and gRPC microservices with OpenAPI documentation, database optimization, and third-party integrations. Our CRM pipeline systems automate lead routing, contract management, and client communication — replacing manual operations with reliable webhook-driven workflows.

How We Work

Our Delivery Process

API Design & Schema

OpenAPI spec first, then implementation. We define every endpoint, payload schema, and error contract before writing code.

Microservices Architecture

Node.js / Python FastAPI microservices with Docker containers, message queues (Redis/BullMQ), and health monitoring.

Database & Search

PostgreSQL with optimized indexes, pgvector for semantic search, and Redis for caching frequently read data.

Integrations

Stripe, Twilio, SendGrid, HubSpot, Salesforce, Slack, WhatsApp API — any third-party service connected via webhook handlers.

Docs & Handoff

Swagger UI documentation, Postman collection, and environment setup guide delivered with the codebase.

FAQs

Common Questions

Do you write API documentation?

Yes — Swagger/OpenAPI docs are auto-generated and kept in sync with the codebase at all times.

Can you integrate with our existing CRM?

We've integrated with HubSpot, Salesforce, Pipedrive, and custom systems. Any system with a REST API can be connected.

What hosting do you recommend?

Railway or Render for most projects; AWS ECS/EKS for enterprise scale. We set up the full infrastructure.
