Why hire senior custom web app development consultants
You need a web app that works on day one, not a prototype that breaks in production.
Most development shops assign junior engineers to your project. You pay for their learning curve and get code that needs rewrites. IRPR assigns only senior engineers with 8+ years of experience. Each engineer has shipped at least 10 production web apps.
Our senior team means your web app is built with proper architecture from the start. We use TypeScript, automated CI/CD pipelines on GitHub Actions, and infrastructure as code on AWS CDK. No tech debt, no shortcuts.
How we differ from generic web development agencies
We don't write code and disappear. We build systems that run your business.
Generic agencies hand off code that works on your laptop but fails under load. They use hourly billing that rewards slow work. They assign juniors and charge senior rates.
IRPR delivers production-grade web apps with monitoring, error tracking, and deployment scripts. We use fixed pricing so you know the cost upfront. Every project includes a 30-day warranty with free bug fixes.
- junior engineers on your project
- hourly billing with no cap
- no CI/CD pipeline
- no monitoring or error tracking
- code owned by agency
- handoff with minimal docs
- senior engineers only (8+ yrs experience)
- fixed price per project
- CI/CD on GitHub Actions from day one
- Sentry error tracking + Datadog monitoring
- you own all source code
- full handoff with architecture docs and runbooks
Our process for building your custom web app
We follow a four-phase process that turns your idea into a production web app.
Every project starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. No surprises. Then we build your MVP in 8-12 weeks with weekly demos.
After release, we provide a 30-day warranty and optional ongoing maintenance. You own the code, the domain, and the infrastructure. You can take it to any team.
What ships with your custom web app
You get more than code. You get a production-ready system.
Every web app we build includes deployment scripts, monitoring, and documentation. You can hand it to any developer or team after launch.
We also set up error tracking, performance monitoring, and automated backups. Your app stays running even when we are not on the clock.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Sentry error tracking configured
- Datadog or CloudWatch monitoring
- Infrastructure as code with AWS CDK
- PostgreSQL database with automated backups
- Architecture decision record (ADR) docs
- Deployment runbook for your team
