Why senior engineers matter for your startup web app
Startups can't afford junior mistakes. Our senior team delivers faster with fewer bugs.
Our senior engineers have an average of 15 years experience. They ship 2x faster than typical agencies.
We use proven patterns and code reviews to ensure quality. This means fewer regressions and faster iterations.
Generic dev shop vs senior startup team
Not all agencies are equal. See the difference.
Most agencies assign junior developers to keep costs low. This leads to technical debt and delayed launches.
IRPR only uses senior engineers who have built production systems for 15+ years.
- Junior developers learn on your dime
- Hourly billing with ballooning costs
- No product strategy
- 6-12 month timelines
- No post-launch support
- Code ownership unclear
- Senior engineers only (15+ years)
- Fixed price from the Roadmap phase
- Product strategy included
- 8-12 week MVP
- Post-launch support included
- Full code ownership
Our 4-phase startup web app development process
From idea to launch, we follow a proven process.
We start with a structured Roadmap so you know the exact scope and price before any coding begins.
Then we build in 2-week sprints with weekly demos. You see progress and can pivot early.
