Every kind of API your stack needs.

Six families of APIs we ship in production for clients across industries.

REST APIs

Resource-oriented JSON APIs with auth, pagination, filtering, versioning, and OpenAPI docs out of the box.

Django REST · FastAPI · Express

Webhooks & Event-Driven

Reliable event delivery with retries, signing, idempotency keys, and dead-letter queues. Stripe, Shopify, custom buses.

SNS / SQS · Kafka · Redis Streams

Real-time APIs

Live dashboards, chats, tracking, notifications. WebSockets, Server-Sent Events, MQTT — choose what fits.

WebSockets · SSE · MQTT

API Gateways

Centralized authentication, rate limiting, caching, request routing, and monitoring across all your services.

AWS API Gateway · Kong · Nginx

Microservices

Containerized, independently deployable services with clear boundaries, contracts, and CI/CD pipelines.

Docker · ECS · Lambda

We integrate with the tools your business already uses.

If it has an API or a webhook, we can wire it into your workflow.

Frequently asked questions.

A Starter API typically ships in 1–2 weeks. A Business Integration takes 3–5 weeks. Enterprise projects range from 6–12 weeks depending on scope. After the discovery call we give you a written timeline before any commitment.

Always. Every project ships with an OpenAPI / Swagger spec, a ready-to-import Postman collection, and a markdown README covering authentication, environments, and common error codes. Your developers can hit the ground running.

Yes. If it has a public API, a webhook, an SDK, or even just an FTP feed, we can wire it in. Over the past 11 years we've integrated 50+ services across fintech, healthcare, e-commerce, and SaaS. Send us the docs and we'll come back with a feasibility call.

By default, in your own AWS account, so you own the infrastructure from day one. We can also deploy to GCP, Azure, DigitalOcean, Render, Fly.io, or your existing VPS — your call. You always keep root credentials.

Yes. We offer monthly retainer plans starting at $390 USD/month, including security patches, dependency updates, monitoring, on-call response, and a fixed bucket of hours for small changes. No retainer required after delivery — but most clients keep us on board.

50% upfront, 50% on delivery. Payment via Stripe, Wise, or wire transfer (USD or EUR accepted). Before kickoff we sign a service contract and an NDA on request. All deliverables, timelines, and acceptance criteria are written down.
