Senior Backend Web Development FirmDevelopment Firm
Hire senior backend engineers who ship production-ready code in 8-12 weeks. We build APIs, microservices, and data pipelines that scale to millions of users.
IRPR is a senior backend web development firm that builds custom backend systems for B2B SaaS, fintech, healthcare, and ecommerce companies. Our engineers work with Node.js, Python, Go, PostgreSQL, Redis, Kafka, and cloud-native stacks on AWS, GCP, and Azure.
Every project ships in 8-12 weeks with a fixed price from $80K to $250K. We handle compliance: HIPAA, PCI-DSS, SOC 2, and FERPA. You get source code ownership, CI/CD pipelines, and production monitoring from day one.
CTOs hire us when their internal teams lack deep backend expertise. Founders hire us to build their first scalable product. Product managers hire us to accelerate a delayed roadmap. VPs of Engineering hire us to augment their senior bench.

What a Senior Backend Web Development Firm Delivers
A senior backend firm builds the foundation your product runs on.
A senior backend web development firm does not just write code - it architects systems that handle production traffic, security audits, and team collaboration. At IRPR, every project starts with a two-week Roadmap phase where your lead engineer documents the system design, data model, API contracts, and infrastructure plan. You approve everything before we write a single line of code.
This approach eliminates rework. Our backend engineers have built systems processing over 10 million requests per day. They design for failure: database replication, caching layers, circuit breakers, and automated rollbacks. The result is a backend that stays up during Black Friday traffic spikes and passes PCI-DSS audits on the first attempt.
IRPR vs. a Generic Backend Agency
Not all backend firms deliver the same quality. Here is the difference.
Many agencies assign junior developers to your project and bill by the hour. They use boilerplate templates, skip automated testing, and hand off code with no documentation. You end up with a fragile backend that costs more to maintain than to build.
IRPR assigns a lead senior engineer with 10+ years of backend experience. We write unit tests, integration tests, and load tests by default. Every project includes production-grade monitoring with Datadog or Sentry and infrastructure-as-code via Terraform. You own the entire codebase from day one.
- Junior developers assigned to your project
- Hourly billing with no budget cap
- No automated tests or CI/CD
- Manual deployment with downtime
- No documentation or onboarding
- Code licensed to agency, not you
- Senior engineers only (10+ years experience)
- Fixed price, agreed in the Roadmap phase
- Full test suite: unit, integration, load
- CI/CD pipelines on GitHub Actions
- System diagrams and API docs auto-generated
- You own 100% of the source code
How We Build Your Backend in 8-12 Weeks
A phased approach that de-risks every step.
Every backend project follows the same four-phase process: Roadmap, Build, Launch, and Optimize. This structure ensures you see progress weekly and can adjust scope before we write code.
In the Roadmap phase (2 weeks), a senior engineer creates a detailed specification: data schema, API endpoints, third-party integrations, infrastructure diagram, and a delivery timeline. You review and approve this document before we start the Build phase.
What Ships With Every Backend Project
You get more than code. You get a production-ready system.
Every backend delivery from IRPR includes the full source code, infrastructure configuration, and monitoring setup. No black boxes. No licensing fees.
We ship the entire system on your AWS, GCP, or Azure account from week one. Your team can see the code, run it locally, and deploy changes using the CI/CD pipeline we build for you.
- Source code in your private Git repo (GitHub, GitLab, or Bitbucket)
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure-as-code with Terraform or Pulumi
- API documentation generated from OpenAPI spec
- Unit, integration, and load test suite
- Production monitoring with Datadog or Sentry
- Database migration scripts (flyway or Alembic)
- Docker Compose file for local development
- Post-launch performance report with recommendations
- 30 days of production support and bug fixes
What we ship in this practice.
Multi-Tenant SaaS Backend
Built a multi-tenant backend for a B2B analytics platform using Node.js, PostgreSQL with row-level security, and Redis caching. Reduced query latency by 60% and supported 500+ tenants on a single database cluster.
HIPAA-Compliant Healthcare API
Developed a HIPAA-compliant API for a telehealth startup. Used Python FastAPI, PostgreSQL with encryption at rest, and AWS HealthLake. Passed HIPAA audit on first attempt and handles 10,000 patient records per hour.
Payment Processing Microservices
Designed a payment processing system with microservices for a fintech company. Stack: Go, Kafka, PostgreSQL, and Stripe Connect. Processed 1 million transactions/month with 99.99% uptime and PCI-DSS Level 1 compliance.
Real-Time Inventory Management System
Built a real-time inventory management backend for a retail chain with 200 stores. Used Node.js, WebSockets, and PostgreSQL. Reduced stockout incidents by 40% and enabled same-day store-to-store transfers.
Learning Management System Backend
Created a FERPA-compliant backend for an edtech platform serving 50 school districts. Used Django REST framework, PostgreSQL, and S3 for content storage. Scaled to handle 100,000 concurrent student sessions during peak hours.
Logistics Route Optimization Engine
Built a route optimization API for a logistics company operating 500 trucks daily. Used Python, PostgreSQL with PostGIS, and a custom algorithm powered by Google OR-Tools. Reduced fuel costs by 15% and improved on-time delivery by 22%.
Why teams hire us.
Only senior engineers
IRPR hires no junior or mid-level developers. Every engineer on your project has 10+ years of backend experience and has shipped at least 5 production systems. You get a lead engineer who can design distributed systems, not just write API endpoints.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. If we agree to build three microservices for $120K, you pay exactly $120K.
Production-ready from day one
We ship code with CI/CD, automated tests, monitoring, and infrastructure-as-code. Your backend is production-ready the moment we push it. We configure Datadog alerts and PagerDuty on-call before launch.
Full source code ownership
You own every line of code we write. No licenses, no restrictions, no vendor lock-in. You can take the code, modify it, and deploy it anywhere. We even transfer the AWS or GCP account to you.
Built for compliance
Our engineers have deep experience with HIPAA, PCI-DSS, SOC 2, and FERPA. We implement encryption, audit logging, access controls, and data retention policies by default. We have helped 20+ clients pass compliance audits.
Global delivery, US time zones
Our team works from 12 time zones but overlaps with US business hours from 9 AM to 6 PM EST. You get daily standups, weekly demos, and async communication via Slack or Linear. Handoffs happen in real time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
