Professional Custom Application Development ConsultantsDevelopment Consultants
We build custom apps for companies that need senior engineers and fixed pricing. 12-week MVPs with production-ready code.
IRPR is a team of senior engineers who act as professional custom application development consultants. We build web apps with Next.js, React, and Node.js, mobile apps with React Native and Flutter, and AI chatbots using Python and LangChain. Every project starts with a detailed roadmap and ends with production-ready code in your repository.
Our consulting model gives you a fixed price and a clear timeline. Most custom applications ship in 8 to 12 weeks, with prices ranging from $80K to $250K depending on complexity. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
We are hired by CTOs who need a senior team fast, startup founders launching a SaaS MVP, healthcare executives building HIPAA-compliant patient portals, and fintech companies requiring PCI-DSS payment systems. Each client gets a dedicated project manager and direct access to engineers.

Why companies hire custom application development consultants
Companies bring in IRPR when internal teams are overloaded or a project needs senior expertise quickly.
Our consultants have built over 200 custom applications across 50 countries. Each engagement starts with a two-week roadmap phase where we define architecture, tech stack, and a fixed price. No hourly billing, no scope creep. We ship production code with CI/CD pipelines, automated tests, and monitoring from day one.
We specialize in regulated industries like healthcare and fintech. Our team has delivered HIPAA-compliant patient portals, PCI-DSS payment systems, and SOC 2 reporting dashboards. Every project includes compliance documentation and penetration testing reports.
The difference between generic dev shops and IRPR's consulting
Most development agencies sell hours. IRPR sells outcomes with fixed pricing and senior-only teams.
Standard dev shops often assign junior developers and bill by the hour. That model leads to delays, hidden costs, and code that needs rewriting. IRPR works differently.
All our engineers are senior level with 8+ years of experience. We give you a fixed quote after a two-week roadmap. You own the full source code, all credentials, and the infrastructure. No lock-in, no recurring fees beyond hosting.
- hourly billing with unclear totals
- junior engineers assigned to your project
- no roadmap before pricing
- code delivered without tests or CI/CD
- no compliance expertise (HIPAA, PCI-DSS)
- source code rights sometimes disputed
- fixed price per project, no surprises
- senior engineers only (8+ years experience)
- two-week roadmap defines scope and cost upfront
- CI/CD, automated tests, Sentry monitoring included
- HIPAA, PCI-DSS, SOC 2 built into every project
- you own 100% of the code from day one
How our custom application consulting works
Every engagement follows four phases: idea, roadmap, product, and release.
Phase 1 (Idea) is a one-week discovery where we validate your concept and define user stories. Phase 2 (Roadmap) delivers a detailed technical plan with wireframes, data model, and a fixed price. This happens in week two and costs a flat $5K.
Phase 3 (Product) is where we build your application in 8-10 weeks using agile sprints. You get a staging environment and weekly demos. Phase 4 (Release) includes production deployment, load testing, and knowledge transfer to your team.
What ships with every custom application from IRPR
When we deliver your application, you get more than just code. Every project includes everything needed to run and maintain the system.
We set up a production environment on AWS or GCP with monitoring, alerts, and automated backups. You get GitHub repositories with full commit history and a CI/CD pipeline that deploys on every merge. All infrastructure is managed with Terraform so you can recreate it in minutes.
Our documentation covers architecture diagrams, API endpoints, environment variables, and disaster recovery steps. You also receive a one-week warranty period where we fix any issues at no extra cost.
- Full source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Production deployment on AWS or GCP with Terraform
- Sentry error tracking and Datadog performance monitoring
- Automated test suite (unit + integration), >80% coverage
- API documentation generated with Swagger/OpenAPI
- 1-week post-release warranty with priority support
- Architecture and deployment runbook for your team
- SSL certificate and domain setup
- One-hour knowledge transfer session via video call
