Premium Custom API Development TeamAPI Development
Build secure, scalable APIs in 12 weeks. Fixed pricing starts at $80K.
IRPR builds premium custom API development teams for companies that need secure, scalable integrations. We use Node.js, Python, and Go for backend services, with PostgreSQL, Redis, and Kafka for data pipelines.
Each project ships in 12 weeks on average, with fixed pricing from $80K to $250K depending on complexity. We handle compliance like HIPAA, PCI-DSS, and SOC 2 from day one.
Our clients are CTOs at SaaS startups needing a scalable API layer, platform product managers integrating third-party data, and DevOps leads building microservices for fintech or healthcare.
Types of software we ship.
REST API Development
Stateless RESTful endpoints with OpenAPI specs. Uses Express.js, FastAPI, or Spring Boot for mobile and web clients.
GraphQL API Development
Unified data query layer with Apollo GraphQL. Clients fetch exactly what they need, reducing over-fetching and under-fetching.
Microservices Gateway
API gateway (Kong, NGINX) to route traffic, handle auth, and rate-limit across dozens of services. Built with Docker and Kubernetes.
Third-Party API Integration
Connect systems to Stripe, Salesforce, HubSpot, or Slack. Custom middleware and webhook handling for data sync.
Real-Time API (WebSocket)
Low-latency APIs for live chat, notifications, or IoT. Uses WebSocket protocol and Redis pub/sub for high concurrency.
Data Pipeline API
Expose processed analytics data via APIs built on AWS Lambda, Step Functions, and Snowflake. Suitable for BI dashboards.
Internal API Platform
Developer portal with Swagger docs, SDK generation (Stoplight), and usage analytics for your engineering teams.
B2B API Product
Package your core service as a revenue-generating API with Stripe billing, usage tracking, and SLA monitoring.
We build for every business type.

We Build Premium Custom API Development Teams That Ship On Time
Our team delivers production-grade APIs with predictable timelines and budgets.
Every project starts with a 2-week discovery phase where we define your data domain, endpoints, and security requirements. We then produce a fixed-price quote and a 12-week delivery plan.
Our senior engineers build in 2-week sprints, demoing working code every Friday. By week 12, you have a deployed, tested, and documented API running in your cloud.
Why a Dedicated API Team Beats Freelancers
Most companies start with a freelance developer, then run into scale and reliability issues.
Freelancers often lack bandwidth for architecture reviews, compliance checks, and deployment automation. IRPR provides a full team with senior engineers, QA, and DevOps.
We guarantee fixed pricing, no single points of failure, and a production-ready system that passes security audits.
- Hourly billing with no budget cap
- No architecture review or code audits
- Single developer can block your timeline
- No compliance or security review
- Documentation is an afterthought
- No CI/CD or deployment automation
- Fixed price from week 2 with clear scope
- Senior-only engineers with architecture review
- Full team backup – no single points of failure
- HIPAA, PCI-DSS, SOC 2 built in
- API docs and test suites ship with code
- CI/CD pipelines on GitHub Actions, AWS CodePipeline
How Our Premium Custom API Development Team Works
We follow a 4-phase process adapted from our IRPR framework.
Phase one – Discovery and Architecture. In two weeks we map your data domain, define endpoints, and produce an OpenAPI spec. Phase two – Roadmap and Pricing. We deliver a fixed-price quote with timeline and risk register.
Phase three – Build and Iterate. Senior engineers sprint in 2-week cycles, demoing working code every Friday. Phase four – Release and Handover. We deploy to your cloud (AWS/GCP/Azure), run load tests, and hand over source code.
Everything That Ships With Your API Project
You get more than just code – you get a production-ready system.
Every project includes a full set of deliverables that let you operate and maintain the API independently.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification document
- Postman collection for manual testing
- CI/CD pipeline (GitHub Actions, CircleCI)
- Unit and integration tests (Jest, PyTest)
- Dockerized services with docker-compose
- Cloud infrastructure as code (Terraform)
- Error monitoring with Sentry
- API uptime dashboard (Grafana + Prometheus)
- One year of maintenance warranty
