Why choose a senior business web app development firm
Most web app development firms hand your project to junior developers. IRPR does not.
We staff every project with senior engineers who have built 200+ products across 50+ countries. Our average engineer has 12 years of experience. No juniors, no offshore teams, no micromanagement.
Your project gets a dedicated senior team of 3-5 engineers. We use React, Node.js, PostgreSQL, and AWS. Every line of code is peer-reviewed. We deploy to production in 12 weeks on average.
The difference between generic dev shops and a senior business web app firm
Generic shops promise everything and deliver scope creep. IRPR delivers a fixed-price, senior-driven process.
When you hire a generic development shop, you often get a project manager who never writes code, junior developers learning on your dime, and hourly billing that balloons your budget. Communication is slow, and code quality is inconsistent.
IRPR assigns senior engineers from day one. We work in 2-week sprints with daily standups. Your code is in your GitHub repo from the first commit. We use CI/CD, automated testing, and Sentry error tracking.
- Junior developers handle your code
- Hourly billing with no cap
- No fixed timeline – delays are common
- Poor documentation and handover
- Reactive support after launch
- Code quality varies by team member
- Senior engineers only (12+ years avg)
- Fixed price – no surprises
- 12-week MVP delivery guaranteed
- Full documentation and knowledge transfer
- Active monitoring and performance tuning
- Automated testing and code review
Our process for building your business web app
We follow a structured 4-phase process that de-risks every project.
Phase 1: Idea validation and technical feasibility. We review your requirements, identify risks, and produce a detailed roadmap. This takes 1-2 weeks and costs a fixed fee.
Phase 2: Design and prototyping. Our UI/UX team creates wireframes and a clickable prototype. You review and approve before any code is written.

Every project ships with a complete set of production-ready deliverables.
We don't just hand you code. We give you a running application with monitoring, CI/CD, and documentation. Your team can take over immediately or we can continue to support you.
