Why choose a top custom backend development vendor for your next project
Your backend is the engine of your product. A poorly built one costs you time, money, and users.
Off the shelf solutions rarely fit complex business logic. Custom backend development gives you full control over performance, security, and scalability. IRPR has shipped over 200 products across 50 countries, from API first startups to enterprise SaaS platforms.
We use the same tools that power billion dollar systems: Node.js, Python, Go, PostgreSQL, Redis, Kafka, and AWS. Every backend includes automated CI/CD, error tracking with Sentry, and 99.9% uptime SLA.
What sets IRPR apart from other backend vendors
Not all development shops deliver the same quality. Here is how we compare.
Many agencies sell you an hourly team with no clear end date. You pay for discovery, rework, and communication overhead. Deadlines slip, budget balloons, and you still own broken code.
IRPR works differently. We build your backend on a fixed price with a clear roadmap. In week two you get a detailed plan with exact costs. No surprises, no scope creep, no hidden fees.
- hourly billing with no cap
- vague timeline estimates
- no compliance experience
- code delivered without tests
- no devops or monitoring setup
- you pay for their learning curve
- fixed price from roadmap (week 2)
- 8-12 week delivery guarantee
- HIPAA, PCI-DSS, SOC 2 proven
- 100% test coverage on critical paths
- CI/CD, Sentry, CloudWatch included
- senior engineers only, 10+ years experience
How we build your custom backend in 4 phases
Our process eliminates uncertainty. You know exactly what ships and when.
We start with a 2 week kickoff to align on architecture and data models. Then we build iteratively, delivering value every sprint.
