Premium Custom Application Development PartnerCustom Application
We build custom applications for serious businesses. Ship in 8-12 weeks with a fixed price.
IRPR is a premium custom application development partner for companies that need high-quality software. We use React, Node.js, Python, AWS, and Postgres to build web and mobile applications that handle complex logic and high traffic.
Every custom application ships with source code ownership, CI/CD pipelines, Sentry error tracking, and full compliance (HIPAA, PCI-DSS, SOC 2). Timelines run 8-12 weeks for an MVP. Fixed prices range from $80,000 to $250,000 depending on scope.
CTOs at funded startups hire us to go from idea to production in weeks. VP of Engineering at mid-market companies use us to offload critical modules. Product Managers at enterprises bring us in for greenfield applications that must meet compliance. Founders with a clear vision choose IRPR because we deliver with no surprises.

Building custom applications at scale
Every application we build ships with measurable performance guarantees.
Our custom applications handle 10,000+ concurrent users and process terabytes of data monthly. We use auto-scaling on AWS with CloudFront CDN, RDS read replicas, and ElastiCache to keep response times under 200ms.
After launch, Sentry error tracking and Datadog monitoring give your team full visibility. We maintain 99.9% uptime SLA and respond to critical incidents within 30 minutes for the first 30 days post-launch.
How IRPR is different from other development partners
Most agencies bill hourly and hand off junior engineers. We do the opposite.
Generic dev shops often start with a vague estimate and ask for more money halfway through. They assign mid-level developers who learn on your dime. Compliance? Usually an afterthought.
IRPR gives you a fixed price after a two-week Roadmap phase. You get senior engineers who have built 200+ products. Compliance (HIPAA, PCI, SOC 2) is built into the architecture from day one.
- Hourly billing with no cap
- Junior developers assigned to your project
- No compliance expertise
- Unclear timelines that slip
- Code ownership is negotiable
- No post-launch support included
- Fixed price from week 2 of the Roadmap
- Senior engineers only (10+ years average)
- HIPAA, PCI-DSS, SOC 2 built into the stack
- 12-week MVP guarantee
- Full code ownership from day one
- 30-day post-launch support with 30-minute response
Our four-phase process for custom application development
We use a structured process to turn your idea into production software in 8-12 weeks.
Every engagement follows the same four phases: Idea, Roadmap, Product, Release. This framework eliminates guesswork and keeps the project on track.
Each phase ends with a clear deliverable. You see progress every two weeks and can change priorities at any checkpoint without penalty.
Everything that ships with your custom application
When we deliver a custom application, you get more than just code.
We believe true ownership means you have everything needed to run and maintain the application. No black boxes, no license fees, no hidden third-party costs.
All code is in your GitHub or GitLab repository from sprint one. We use IaC (Terraform) so you can recreate infrastructure with a single command.
- Full source code in your repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Staging and production environments on AWS or GCP
- Automated test suite (unit, integration, e2e)
- Architecture and deployment documentation
- Admin panel with user management and audit logs
- Data backup and disaster recovery scripts
- 30-day post-launch support with 30-minute response SLA
- One-year free minor updates and security patches

Why teams hire us.
Fixed price from week 2
We quote a fixed price after the two-week Roadmap phase. No hourly billing. No surprise invoices. If the scope changes, you approve a change order before any work starts.
Senior engineers only
Every engineer on your project has 10+ years of experience. We do not staff juniors. You get a lead architect who has shipped production applications in your industry.
12-week MVPs guaranteed
We deliver a production-ready MVP in 8 to 12 weeks. If we miss the deadline, the next two weeks are free. That has never happened in 200+ projects.
Full code ownership
You own every line of code from day one. No license fees. No lock-in. The code lives in your repository with full commit history.
Compliance built in, not bolted on
HIPAA, PCI-DSS, and SOC 2 controls are part of the architecture, not an afterthought. We encrypt data at rest and in transit, log all access, and run annual penetration tests.
Post-launch support with SLAs
After release, we stay on for 30 days with a 30-minute critical response SLA. We also offer ongoing maintenance and feature development at the same fixed-price model.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
