Senior Web Application Development VendorDevelopment Vendor
You need a senior web application development vendor with a proven track record. We ship production-grade code in 8 to 12 weeks at fixed prices.
IRPR builds senior-level web applications using Next.js, React, Node.js, and PostgreSQL. We focus on production-ready code with CI/CD and AWS infrastructure, giving you a vendor that matches your internal team's standards.
Each project ships with source code ownership, automated testing, and Sentry monitoring. Timelines range from 8 to 12 weeks for MVPs, with fixed pricing between $80,000 and $250,000. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA across every engagement.
Startup founders hire us to build their core product without hiring a full team. VPs of engineering use us to accelerate delivery on critical initiatives. CTOs at mid-market companies choose IRPR when internal teams are at capacity. Product managers need us to ship features that require senior talent.

Why a senior vendor matters for web application development
The skills of individual engineers define your project's ceiling.
When you hire a senior web application development vendor, you get engineers who have shipped 200+ products across 50+ countries. Every developer averages 10+ years of experience, working with modern stacks like Next.js, NestJS, and AWS Lambda.
Junior-heavy teams produce code that requires rewrites. Our senior team delivers production-grade code on the first iteration. We use TypeScript, automated testing, and CI/CD pipelines from day one, cutting maintenance costs by up to 40% in the first year.
Generic development shops vs. a senior web application development vendor
The difference is in the output, not the promises.
Generic shops staff with junior or mid-level talent. They hide hourly billing and scope creep in contracts. Their code lacks testing and documentation, leading to technical debt that slows future work.
IRPR assigns a small team of senior engineers who own the full stack. You get TypeScript, automated CI/CD, and deployment to AWS. Every project has a fixed price after the Roadmap phase (week 2). No hidden fees, no ambiguous deliverables.
- Junior and mid-level developers
- Hourly billing with unpredictable costs
- Scope creep from vague specifications
- Code with minimal testing or documentation
- Slow communication across time zones
- Ownership of code often unclear
- Senior engineers with 10+ years average experience
- Fixed pricing agreed in the Roadmap phase (week 2)
- Clear scope based on a detailed blueprint
- Full test coverage and JSDoc documentation
- Async-first communication with daily overlap for US time zones
- You own all source code and infrastructure
Our process for building as your senior web application development vendor
We follow a structured four-phase approach to deliver production software.
From the first call to deployment, every project goes through the same proven phases. This guarantees predictability in cost, timeline, and quality.
Each phase includes clear deliverables and a gate review. You always know exactly what ships and when.
What ships with every engagement from your senior web application development vendor
Every project includes a standard set of deliverables that ensures you can run the product independently.
You are never locked in. Our contract gives you full ownership of all code, infrastructure, and documentation from day one.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests and linting
- Infrastructure as code using Terraform or CDK
- Sentry error tracking and Datadog monitoring
- Automated end-to-end tests with Playwright
- API documentation generated from OpenAPI specs
- User guide for admin and support workflows
- One year of security patches and minor updates
- Deployment runbook for future releases
- SLA with 4-hour critical incident response
What we ship in this practice.
Patient Portal for a Telemedicine Startup
We built a HIPAA-compliant patient portal with video consults, appointment scheduling, and lab result uploads. The startup reduced no-show rates by 34% and onboarded 12,000 patients in 3 months. Tech stack: Next.js, WebRTC, PostgreSQL hosted on AWS.
Real-Time Fleet Dashboard for a Logistics Company
We developed a live tracking dashboard that shows 500+ vehicles on a map with fuel consumption and driver alerts. The client saved $2.4M annually in fuel costs through optimized routing. Tech stack: React, Mapbox, Redis, and a Go backend.
Multi-Currency Payment Platform for a Fintech Firm
We created a PCI-DSS compliant platform that processes 15,000 transactions daily across 10 currencies. Integration with Plaid and Stripe reduced manual reconciliation from 6 hours to 20 minutes per day. Tech stack: Node.js, PostgreSQL, AWS Fargate.
Subscription Management SaaS for a Media Company
We built a subscription engine that handles tiered pricing, free trials, and churn analytics. The client's monthly recurring revenue grew 120% in the first quarter. Tech stack: Next.js, Stripe Billing, and a Python microservice for analytics.
E-Learning Platform for an Education Nonprofit
We developed a FERPA-compliant platform with course authoring, quizzes, and progress tracking. The nonprofit reached 50,000 students in underserved areas within 6 months. Tech stack: Vue.js, Django REST framework, AWS S3 for content delivery.
Inventory Forecasting Tool for a Manufacturer
We built a dashboard that predicts stockouts using 3 years of historical data and machine learning. The manufacturer reduced excess inventory by 22% and cut warehousing costs by $1.8M. Tech stack: React, Python Flask, PostgreSQL, and TensorFlow for forecasting.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
Every engineer on your project has 10+ years of experience across multiple industries. We do not hire junior developers or outsource to less experienced teams.
Production-grade code from day one
We write TypeScript, enforce strict linting, and maintain 90%+ test coverage. Every project ships with automated CI/CD pipelines, so you can deploy at any time.
Full ownership and transparency
You own all source code, infrastructure configurations, and documentation. We use your preferred tools (GitHub, AWS, Datadog) and give you full admin access.
Compliance is built-in, not bolted on
We have delivered HIPAA, PCI-DSS, SOC 2, and FERPA compliant systems. Our checklists and infrastructure templates are pre-audited for these standards.
We ship in 8-12 weeks
A focused senior team can deliver a production-ready MVP in 8 to 12 weeks. Faster than hiring your own team, and with the same quality as an internal squad.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
