Why you need a senior scalable web app development firm
A web app built by junior freelancers will break at 1,000 users. A web app from IRPR handles 1 million.
Scalability is not an afterthought. It is the foundation. IRPR designs every web app with horizontal scaling, database sharding, and caching layers from day one. We use AWS Auto Scaling, Redis, and CDN distribution so your app stays fast under any load. Our senior engineers have built systems that process 10 million requests per day for clients in fintech and healthcare.
Most web app development firms charge by the hour and deliver late. IRPR gives you a fixed price and a fixed timeline. You know the cost before we write a single line of code. And because we only hire senior engineers with 10+ years of experience, we ship in 8-12 weeks, not 8-12 months.
How IRPR compares to other scalable web app development firms
Most agencies sell you junior developers at senior rates. IRPR gives you actual senior engineers who own the outcome.
We have seen too many projects fail because the agency staffed junior developers who had never built a production system at scale. IRPR hires only engineers with 10+ years of experience. Every developer has shipped at least 5 production-grade web apps. You get a single point of contact and a team that stays consistent through the entire project.
Our process eliminates the two biggest risks: scope creep and surprise bills. The Roadmap phase (week 2) locks down every feature, integration, and milestone. After that, the price does not change. We deliver on time because we have done it 200 times before.
- Staffs junior and mid-level developers
- Charges hourly with no fixed scope
- Delivers 3-6 months late on average
- No compliance expertise (HIPAA, PCI-DSS)
- Code quality drops at scale
- You manage the project yourself
- Senior engineers only, 10+ years experience
- Fixed price from the Roadmap phase
- 8-12 week delivery, 98% on-time
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Scalable architecture from day one
- We manage the project, you get weekly demos
Our process for building scalable web apps
IRPR follows a four-phase process that guarantees your web app ships on time and on budget.
Every project starts with the Idea phase. You tell us your goals, users, and constraints. We review your market and technical requirements. This takes 1 week and costs nothing if you decide not to proceed.
The Roadmap phase (week 2) produces a detailed project plan with every feature, integration, and milestone. You get a fixed price and a fixed timeline. No surprises.
What ships with your scalable web app
You own everything. Source code, infrastructure, and documentation. No lock-in, no license fees.
When IRPR delivers your web app, you get a complete production-ready system. We set up CI/CD pipelines on GitHub Actions, error tracking with Sentry, and uptime monitoring with Datadog. Every project includes automated tests, a staging environment, and a deployment runbook.
You also get a 30-day warranty where we fix any bugs for free. After that, we offer maintenance contracts starting at $5K per month. But many clients choose to run the app themselves because we document everything.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Datadog dashboards for uptime and latency
- Automated unit, integration, and E2E tests
- Staging and production environments on AWS
- Deployment runbook and architecture docs
- Admin panel for managing users and data
- 30-day bug fix warranty
- Post-launch maintenance options from $5K/month
