Senior Startup Web App Development TeamDevelopment Team
Our senior engineers have shipped 200+ products for startups. You get a fixed-price MVP in 8-12 weeks.
IRPR builds startup web apps with a team of senior engineers who have shipped over 200 products. We use React, Next.js, Node.js, TypeScript, and AWS to deliver production-ready MVPs fast.
Every project ships in 8-12 weeks at a fixed price between $80K and $250K. We handle compliance like SOC 2, HIPAA, and PCI-DSS, so you can launch without legal delays.
We work with startup founders, CTOs of early-stage companies, product managers at venture-backed startups, and teams who need a technical co-founder substitute to build their first product.

Senior startup web app development team by the numbers
Our track record shows consistent delivery for startups worldwide.
IRPR has shipped over 200 web apps for startups in 50+ countries. Every project is built by a team of senior engineers with an average of 12 years of experience each.
We maintain a 98% on-time delivery rate and a 99.9% uptime on all deployed applications. Our fixed-price model means no budget surprises from week 2.
How we compare to other development teams
Not all teams are built the same. Here is the difference.
Many agencies staff projects with junior developers and bill by the hour. That model rewards slow work and unclear deadlines.
IRPR assigns only senior engineers, locks the price in the Roadmap phase, and delivers a working product in 8-12 weeks. No scope creep, no surprises.
- Hourly billing that encourages inefficiency
- Junior developers learning on your dime
- No compliance experience (HIPAA, SOC 2)
- Vague timelines that slip by months
- Code ownership often disputed
- No post-launch support plan
- Fixed price from week 2, no hourly billing
- Only senior engineers with 10+ years each
- Built-in compliance for healthcare, fintech, SaaS
- 8-12 week delivery, hard deadline
- Full code ownership from day one
- DevOps, monitoring, and error tracking included
Our process for building your startup web app
We follow a proven 4-phase framework that reduces risk and speeds delivery.
Every project starts with an Idea phase where we align on your vision and validate assumptions. Then we produce a detailed Roadmap with fixed scope and price.
The Product phase is a 8-12 week sprint where senior engineers build your MVP. The Release phase includes deployment to production with monitoring and documentation.
Everything that ships with your MVP
You get more than just code. These are the deliverables included in every project.
Every web app we build comes with production-ready infrastructure, documentation, and monitoring. You can hand it to any internal team or continue with IRPR for iteration.
- Source code in your private Git repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking with alerting
- Performance monitoring with Datadog or New Relic
- User authentication (OAuth, JWT, or magic links)
- Admin dashboard with user management
- API documentation (Swagger/OpenAPI)
- Dockerized deployment configuration for AWS
- UI component library (Storybook) for reuse
- Automated test suite (unit + integration + E2E)
What we ship in this practice.
SaaS dashboard for a logistics startup
Built a real-time shipment tracking dashboard with React, Node, and PostgreSQL. The startup reduced manual tracking by 12 hours per week and onboarded 10+ enterprise customers in the first month.
Telemedicine platform for a health tech startup
Developed a HIPAA-compliant video consultation app with WebRTC, React, and AWS. The platform handled 500 consultations per day within 8 weeks of launch and secured a second round of funding.
Subscription e-commerce store for a fashion brand
Created a headless e-commerce web app using Next.js, Stripe, and Shopify API. The client saw a 40% increase in conversion rate and a 25% reduction in cart abandonment within 6 weeks.
Property management marketplace for a real estate startup
Built a two-sided marketplace with property listings, tenant applications, and rent payments. The platform processed $2M in lease transactions in the first quarter after launch.
Learning management system for an edtech startup
Delivered a FERPA-compliant LMS with video courses, quizzes, and progress tracking using React and Python. The platform scaled to 10,000 active students in the first 3 months.
Payment processing API for a fintech startup
Implemented a PCI-DSS compliant payment gateway API with Node, PostgreSQL, and Stripe Connect. The API processed 50,000 transactions per day with 99.95% uptime, enabling the startup to launch in 3 new countries.
Why teams hire us.
Senior engineers only, no juniors
Every IRPR engineer has at least 10 years of experience. You never get a junior developer learning on your project. Our team collectively holds 15+ AWS certifications.
Fixed price from week 2
After the Roadmap phase in week 2, we lock the price and scope. No hourly billing, no surprise invoices, no scope creep charges. You know the budget before we build.
8-12 week delivery, hard deadline
We ship your MVP in 8-12 weeks, not months. 98% of our projects finish on time. You get a working product you can show to investors and early users.
Full code ownership
You own every line of code we write. We put the source code in your private repository from day one. There is no licensing fee or locked-in vendor.
Compliance built in from the start
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture, not as an afterthought. Over 40% of our projects involve regulated industries.
DevOps and monitoring included
Every project ships with a CI/CD pipeline, error tracking via Sentry, and performance monitoring. Your team can deploy changes immediately after launch.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
