Senior Backend Web Development AgencyAgency
We build backend systems that scale from day one. Your API, microservices, or data pipeline ships in 8-12 weeks.
IRPR is a senior backend web development agency. We build APIs, microservices, and event-driven architectures using Node.js, Python, Go, PostgreSQL, Redis, Kafka, and AWS. Every line of code is written by senior engineers with 10+ years of experience.
Your backend ships in 8-12 weeks at a fixed price of $80K-$250K. We handle all compliance needs including SOC 2, HIPAA, and PCI-DSS. Source code is fully owned by you from day one.
We work with CTOs scaling their SaaS, founders who need a production-ready backend for their MVP, enterprise engineering teams modernizing legacy systems, and product managers hiring for a specific backend module.
Types of software we ship.
API Gateway
Centralized entry point for multiple backend services. Built with Kong or AWS API Gateway. Handles rate limiting, auth, and routing.
Microservices Platform
Decoupled backend architecture with Docker and Kubernetes. Each service scales independently. Uses gRPC or RabbitMQ for inter-service communication.
Event-Driven System
Asynchronous processing with Apache Kafka or AWS SQS. Handles high-throughput data streams, real-time notifications, and workflow automation.
Real-Time Data Pipeline
Stream processing with Apache Flink or Spark. Ingests, transforms, and stores data from multiple sources with low latency.
Authentication Service
Custom auth with OAuth 2.0, SAML, or JWT. Supports SSO, MFA, and role-based access control. Built with Auth0 or custom Passport.js.
Payment Processing Engine
Handles subscriptions, invoicing, and multi-currency payments. Integrates with Stripe, Braintree, or Adyen. PCI-DSS compliant.
Content Management API
Headless CMS backend with GraphQL or REST. Manages content, media, and localization. Built on Strapi or custom Node.js.
Integration Middleware
Connects SaaS tools like Salesforce, HubSpot, and Slack. Uses webhooks, APIs, and scheduled syncs. Built with Node.js and Python.
We build for every business type.

Why hire a senior backend web development agency
A senior backend agency eliminates guesswork and delivers production-ready systems on time and on budget.
IRPR has shipped 200+ backend systems. Our engineers average 15 years of experience. We use Node.js, Python, Go, PostgreSQL, Redis, Kafka, and AWS. Each project includes automated testing, CI/CD, and monitoring from day one.
We follow a fixed-price model. After a 2-week Roadmap phase (starting at $8K), you get a fixed quote. No hourly billing. No scope creep. The average MVP ships in 8-12 weeks.
How we differ from generic development shops
Generic shops assign junior engineers and bill by the hour. IRPR sends senior engineers and charges a fixed price.
Every IRPR project is staffed with 2-3 senior backend engineers. No juniors. No offshore teams. Your lead engineer has 15+ years of experience and stays on your project from start to finish.
We include DevOps, security audits, and performance testing as part of every engagement. You get a live demo environment within the first 4 weeks.
- Assigns junior or mid-level developers
- Bills by the hour - no cost certainty
- Hands over code with minimal documentation
- No DevOps or CI/CD included
- Scope changes increase timeline by months
- No compliance expertise
- Senior engineers with 15+ years average
- Fixed price after 2-week Roadmap phase
- Full source code ownership from day one
- CI/CD pipeline with GitHub Actions included
- 8-12 week timeline, 98% on-time
- SOC 2, HIPAA, PCI-DSS compliant by default
Our backend development process
Four phases. No surprises. You see working software every 2 weeks.
Phase 1: Idea - we map your core features, data model, and API endpoints. Phase 2: Roadmap - we produce a fixed-price quote, technical design document, and project timeline. This phase takes 2 weeks and costs $8K.
Phase 3: Product - we build in 2-week sprints with daily standups and biweekly demos. Phase 4: Release - we deploy to production, run a 2-week monitoring period, and hand over full ownership.
What ships with every backend project
Every project includes more than just code. Here is what you receive.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Database schema and migration scripts
- API documentation (OpenAPI / Swagger)
- Sentry error tracking and monitoring
- Logging with Datadog or ELK stack
- Automated test suite (unit + integration)
- Deployment playbook and runbook
- Performance benchmark report
- 2-week post-release monitoring and support
What we ship in this practice.
Scalable API for a Fintech Startup
IRPR built a RESTful API handling 10,000 requests per second. Used Node.js, PostgreSQL, Redis, and Stripe. Reduced transaction latency by 40%. PCI-DSS compliant from day one.
Microservices Backend for a SaaS Platform
Designed a 12-service microservices architecture with Kubernetes and gRPC. Handles 500,000 active users. Automated CI/CD reduced deployment time from 2 hours to 15 minutes.
Real-Time Data Pipeline for a Logistics Company
Built an event-driven pipeline processing 1 million GPS events per hour using Apache Kafka and Node.js. Cut data latency from 5 minutes to under 10 seconds.
HIPAA-Compliant Backend for a Telehealth Platform
Developed a secure backend storing patient data with end-to-end encryption. Used Python, FastAPI, PostgreSQL, and AWS HealthLake. Passed HIPAA audit on first try.
Authentication Service for an Enterprise SaaS
Built a custom OAuth 2.0 authentication service supporting SAML, MFA, and role-based access control. Integrated with Azure AD. Reduced login time by 60%.
Content Management API for a Media Company

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing. No surprise invoices. Your budget is locked from day one.
Senior engineers only
We do not hire juniors. Our engineers average 15 years of experience. You work directly with the person building your backend, not an account manager.
Async-first communication
We work across time zones using GitHub, Slack, and Notion. We maintain 4-hour overlap with US time zones. You get daily updates without endless meetings.
Compliance built in
We handle SOC 2, HIPAA, PCI-DSS, and GDPR as part of every project. No separate compliance audit needed. We use encrypted databases, audit logs, and secure APIs.
8-12 week MVP delivery
From idea to production in 8-12 weeks. You see working software every 2 weeks. We deploy to staging at week 4 and production by week 12 on average.
Full ownership of code
You own 100% of the source code, database schema, and documentation from day one. No licensing fees. No proprietary frameworks. You can take it anywhere.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
