Why You Need a Senior Backend App Development Vendor
Backend development is the hardest part of any product. Most agencies fail because they assign junior developers to complex system design.
IRPR is a senior backend app development vendor that only hires engineers with 10+ years of experience. We do not have junior developers. Every architect we assign has shipped at least 5 production backends. This means your project starts with the right database schema and API design from day one.
We use TypeScript, Go, and Python for backend work. All deployments run on AWS EKS or GCP GKE with auto-scaling. We include Sentry error tracking, Datadog monitoring, and PagerDuty alerting in every project. You get a system that stays up at 99.9% uptime.
How IRPR Differs from Generic Backend Vendors
Most backend vendors assign junior talent, bill hourly, and deliver incomplete systems. IRPR is built differently.
Generic dev shops hire recent graduates to cut costs. They use outdated stacks like PHP or Ruby on Rails without modern CI/CD. Their projects often run over budget because they bill hourly and change requirements mid-stream.
IRPR assigns senior engineers, uses Node.js, Go, and Python with automated testing and infrastructure-as-code. We quote a fixed price in week 2 after the Roadmap phase. You never pay for learning curves.
- Junior developers with less than 3 years experience
- Hourly billing that increases when scope changes
- No automated CI/CD, manual deploys
- No monitoring or error tracking included
- You own no infrastructure, vendor lock-in
- Delivery takes 6+ months due to churn
- Senior engineers with 10+ years of experience
- Fixed price after the Roadmap phase, no surprises
- CI/CD with GitHub Actions and automatic deployments
- Sentry error tracking and Datadog monitoring included
- Full source code and cloud account ownership
- 8-12 weeks to production MVP
Our Backend Development Process: 4 Phases to Production
We follow the Idea - Roadmap - Product - Release framework. Each phase has a clear deliverable and milestone.
The process starts with a 2-day discovery session where we map your data model, API endpoints, and third-party integrations. Then we build a detailed Roadmap with wireframes, database schema, and a fixed price quote.
During the Product phase, we code and test each endpoint in 2-week sprints. The Release phase includes load testing, security audit, and deployment to your cloud account.
What Ships When You Hire IRPR as Your Backend Vendor
Every backend project includes these deliverables by default. No hidden costs or missing pieces.
You get everything you need to run the backend independently. IRPR sets up your cloud account, deploys the code, and hands over all passwords and access keys. We also provide a runbook for your operations team.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Dockerized microservices on AWS ECS or GCP Cloud Run
- PostgreSQL database with schema migrations
- RESTful or GraphQL API with auto-generated Swagger docs
- Sentry error tracking and Datadog monitoring dashboards
- PagerDuty alerting for production incidents
- Deployment runbook with rollback procedures
- Load test report using k6 with 1000+ concurrent users
- Security audit report covering OWASP top 10
