Hire Senior Backend Development ConsultantsDevelopment Consultants
We build scalable backend systems that handle millions of requests. 200+ products shipped, fixed price, 8-12 week delivery.
IRPR provides senior backend development consultants who design and build production-grade systems using Node.js, Python, Go, and Java. We handle databases (PostgreSQL, MongoDB, Redis), message queues (Kafka, RabbitMQ), and cloud infrastructure (AWS, Azure, GCP). Every consultant has 10+ years of experience and has shipped at least 5 products to production.
A typical engagement runs 12-14 weeks and costs $80K-$250K depending on scope. We deliver a fully functional backend with CI/CD, monitoring, and documentation. Our systems comply with HIPAA, PCI-DSS, SOC 2, and FERPA as needed. You own the code from day one.
Founders hire us when their MVP needs to scale. CTOs hire us to rebuild legacy backends. Product managers hire us to add complex features like real-time sync or payment processing. We work as an extension of your team, not a replacement.
Types of software we ship.

Why companies need senior backend development consultants
A junior developer can build a CRUD app. A senior backend development consultant builds systems that survive Black Friday traffic.
IRPR's senior backend development consultants have shipped 200+ products across 50 countries. We use Node.js, Python, Go, and Java with PostgreSQL, Redis, and Kafka. Every system includes CI/CD pipelines on GitHub Actions, error tracking with Sentry, and uptime monitoring with Datadog. We guarantee 99.9% uptime for production systems.
Our consultants work async-first with 4+ hours of daily overlap with your team. We do code reviews, pair programming, and knowledge transfer. You get a senior engineer who writes clean, tested, documented code -- not a cowboy who leaves a mess.
The difference between generic dev shops and IRPR
Most agencies staff junior devs and charge by the hour. IRPR gives you a senior backend development consultant at a fixed price.
Generic dev shops rotate developers mid-project. You never know who is writing your code. They use hourly billing, so scope creep is their profit center. They avoid compliance because it is hard. They deliver code without tests or documentation.
IRPR assigns the same senior backend development consultant from kickoff to launch. We quote a fixed price in the Roadmap phase (week 2). We handle HIPAA, PCI-DSS, SOC 2, and FERPA. Every delivery includes unit tests, integration tests, and a runbook.
- Rotates developers mid-project
- Hourly billing with no cap
- Avoids compliance work
- Delivers code without tests
- No documentation or runbook
- Scope creep increases cost
- Same consultant from start to finish
- Fixed price quoted in week 2
- Handles HIPAA, PCI-DSS, SOC 2, FERPA
- Unit + integration tests on every PR
- Runbook and architecture docs included
- Scope changes quoted before work starts
How our senior backend development consultants deliver
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline.
In the Idea phase (week 1), we map your requirements, data model, and integration points. We identify compliance needs (HIPAA, PCI-DSS, SOC 2) and choose the tech stack. You get a system design document with diagrams.
The Roadmap phase (week 2) produces a fixed-price quote, a 12-week build plan, and a risk register. The Product phase builds the backend in 2-week sprints with demos every Friday. The Release phase includes load testing, security audit, and deployment.
What ships with every backend engagement
You get more than code. Every engagement includes the tools and documentation you need to run the system yourself.
IRPR's senior backend development consultants deliver a complete package. You get source code in your private GitHub repo, a CI/CD pipeline that runs tests and deploys automatically, and production monitoring with Datadog and Sentry. Every API includes an OpenAPI spec and Postman collection.
We also provide a runbook with deployment instructions, database migration scripts, and a disaster recovery plan. Your team can take over maintenance immediately or we can stay on for ongoing support.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog monitoring dashboards
- OpenAPI spec for all APIs
- Postman collection for testing
- Database migration scripts
- Runbook with deployment steps
- Disaster recovery plan
- Architecture documentation (draw.io or Mermaid)

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Same consultant end to end
The senior backend development consultant who joins your kickoff call is the same person who deploys to production. No handoffs, no rotation, no context loss.
Compliance built in, not bolted on

Production-ready from day one
Every delivery includes CI/CD, monitoring, error tracking, and a runbook. Your system is ready for load testing and security review the moment it ships.
Async-first with daily overlap
Our team spans 50+ countries, but we maintain 4+ hours of daily overlap with your timezone. You get daily standups, Slack access, and video calls as needed.
