Senior Backend Web Development ServicesWeb Development
You get a senior backend engineer who leads the architecture. Fixed price, 8-12 week delivery, full code ownership.
IRPR provides senior backend web development services to build production-grade APIs, microservices, and data pipelines. Our engineers work with Node.js, Python, Go, Rust, and Java on PostgreSQL, Redis, Kafka, and AWS or GCP.
Every project ships in 8 to 12 weeks at a fixed price starting at $80K. We handle PCI-DSS for fintech, HIPAA for healthcare, SOC 2 for SaaS, and ISO 9001 for manufacturing. You own 100% of the source code.
Founders building a SaaS MVP hire us when they need a production-ready backend in 12 weeks. CTOs scaling an existing product hire us to refactor monolithic codebases into microservices. Engineering managers needing a senior architect hire us to own the API design and database schema from day one.

What senior backend web development services include
Every engagement ships a production-ready backend with documentation, tests, and deployment scripts.
Our senior backend engineers write code in Node.js, Python, Go, or Rust depending on the use case. We use PostgreSQL for relational data, Redis for caching, and Kafka for event streaming. Every API is documented in OpenAPI 3.0 and has automated tests covering 90%+ of the codebase.
Deployment is on AWS ECS, Google Cloud Run, or your own VPS. We set up CI/CD with GitHub Actions, monitoring with Datadog or Grafana, and error tracking with Sentry. Your backend will handle 100,000 concurrent requests within the first month of launch.
How IRPR differs from generic dev shops
You are not getting a junior developer or a body shop. You get a senior engineer who owns the architecture end to end.
Most backend development agencies assign a mix of juniors and seniors, with the senior only reviewing code. At IRPR, the person you speak with in the discovery call is the same person writing the code. We do not outsource to offshore teams or use low-cost labor.
We charge a fixed price for a defined scope, not hourly. You know the budget before we write a single line of code. If the scope changes, we adjust the price transparently. No surprise bills, no time tracking.
- Assigns mid-level or junior developers
- Charges hourly with weekly timesheets
- No upfront architecture review
- Code quality varies per engineer
- Takes 16-24 weeks for MVP
- Hands off code without documentation
- Senior engineers with 10+ years of experience
- Fixed price agreed in the Roadmap phase
- Architecture review in week 1
- Automated tests, CI/CD, and code reviews
- Delivery in 8-12 weeks
- Full documentation and deployment runbooks
Our process for senior backend development
We follow a four-phase process from idea to release.
Phase one is the Roadmap. In week 2, you get a detailed specification with API endpoints, database schema, and a fixed price. If you approve, we build. If not, you pay only for the Roadmap.
Phase two is Product engineering. Our senior backend engineer builds the API, database migrations, tests, and deployment scripts. You get weekly demos and a staging environment to see progress.
What ships with every backend project
You get everything you need to run and maintain the backend yourself after launch.
We do not hold your code hostage. Every project includes a handoff with documentation, deployment scripts, and a knowledge transfer session. Your team takes over with no friction.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- API documentation in OpenAPI 3.0 (Swagger UI)
- Database schema diagrams and migration scripts
- Automated test suite (unit, integration, and load tests)
- Deployment runbooks for AWS ECS or Google Cloud Run
- Sentry error tracking and Datadog monitoring
- Postman collection for API testing
- 1-hour knowledge transfer session with your team
- 30-day warranty for production bugs
What we ship in this practice.
Payment gateway backend for fintech startup
Built a PCI-DSS compliant payment processing API that handles 10,000 transactions per minute. Integrated with Stripe Connect and Plaid for bank verification. Tech stack: Node.js, PostgreSQL, Redis, Stripe SDK, Datadog. Reduced payment failure rate from 3% to 0.5%.
EHR backend for telemedicine platform
Engineered a HIPAA-compliant patient data API with FHIR R4 schema. Supports 500 concurrent providers and 1M patient records. Tech stack: Python FastAPI, PostgreSQL, FHIR, AWS HealthLake. Cut patient record retrieval time from 8 seconds to 0.2 seconds.
Marketplace backend for multi-vendor ecommerce

Why teams hire us.
Senior engineers only, no juniors
Every backend engineer at IRPR has 10+ years of production experience. You never get a junior developer learning on your project. The engineer writing the code is the same person who presents the architecture.
Fixed price, not hourly
We quote a fixed price after the Roadmap phase. You know the budget before we start building. No time tracking, no hourly billing, no surprise overhead fees.
Compliance built in from day one
We handle HIPAA, PCI-DSS, SOC 2, and GDPR compliance at the architecture level. Your backend passes compliance audits without rework. We have done this for 40+ regulated projects.
Full code ownership
You own 100% of the source code, documentation, and deployment scripts. There are no licensing fees, no ongoing royalties, and no vendor lock-in. You can take the code to any team after launch.
Production-grade deployment
We ship with CI/CD pipelines, automated testing, monitoring, and error tracking. Your backend goes live on day one with Datadog alerts, Sentry error tracking, and 99.9% uptime SLAs.
8-12 week delivery
Most backends ship in 8 to 12 weeks from kickoff to production. We use weekly sprints with demos so you see progress every Friday. 98% of our projects deliver on time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
