Experienced Full Stack App Development ConsultantsApp Development
We ship your product in 8-12 weeks with a fixed price. No hourly billing, no scope creep, no surprises.
IRPR builds full stack apps for startups and mid-market companies. We use React, Next.js, Node.js, Python, PostgreSQL, and AWS to ship production-ready products. Every project includes a senior engineer as your lead architect.
We ship an MVP in 8-12 weeks for $80K to $250K fixed price. The Roadmap phase locks the scope and price by week 2. You get a CI/CD pipeline, error monitoring, and full source code ownership.
We work with founders who need to validate an idea in 3 months, CTOs who need to extend their team without hiring overhead, and product managers who need a reliable build partner for a compliance-heavy project.

Why hire experienced full stack app development consultants
You get a team that designs, builds, and ships your product with no handoff gaps.
IRPR assigns a senior engineer as your lead from day one. That person writes code, reviews every pull request, and talks to you directly. No account managers, no junior devs learning on your budget. Our average engineer has 10+ years of experience and has shipped 15+ production apps.
We handle the entire stack: frontend (React, Next.js, Vue), backend (Node.js, Python, Go), database (PostgreSQL, MongoDB, DynamoDB), cloud (AWS, GCP, Azure), and DevOps (Docker, Kubernetes, CI/CD). You get one team that owns every layer.
What makes IRPR different from other full stack consultants
Most agencies bill by the hour and change scope. We do the opposite.
A typical engagement with IRPR starts with a 2-week Roadmap phase. We analyze your requirements, design the architecture, and produce a fixed price quote for the full build. That quote does not change unless you change the spec. No surprise invoices at the end of the month.
We work async-first with daily standups via Slack and weekly video calls. You see progress in real time on a shared Trello board and a staging environment. Every Thursday we deploy new features to staging for your review. This rhythm keeps the project predictable and transparent.
- Billable by the hour with no cap
- Junior devs assigned to save cost
- Scope changes mid-project without new quote
- No dedicated lead engineer
- Delivery slips week by week
- You get code, not a running product
- Fixed price locked in week 2
- Senior engineers only (10+ years avg)
- Scope changes quoted before work starts
- One lead engineer who owns architecture
- 8-12 week timeline with weekly demo
- You get a deployed app with CI/CD and monitoring
Our full stack development process
We follow a 4-phase framework from idea to release.
Phase 1 is Idea validation. We review your concept, target market, and technical constraints. Phase 2 is Roadmap — a 2-week sprint that produces a detailed spec, wireframes, and a fixed price quote. Phase 3 is Product — the build sprint where we code, test, and deploy. Phase 4 is Release — we help you launch and hand over operations.
Each phase has clear deliverables. By the end of the Roadmap phase you know exactly what you will get, when you will get it, and what it costs. No ambiguity, no hidden work, no death march.
What ships with your full stack app
You get more than code. You get a production-ready system.
Every project includes a CI/CD pipeline (GitHub Actions or GitLab CI), automated tests (Jest, Cypress, Playwright), error monitoring (Sentry), performance monitoring (Datadog), and infrastructure-as-code (Terraform or CloudFormation). We also include a deployment guide and a one-hour handoff call with your team.
We do not hand over a zip file. You get a running application on your own AWS/GCP/Azure account with all credentials, secrets rotated, and a backup strategy configured. Your team can start making changes immediately.
- Full source code in your private GitHub repository
- CI/CD pipeline with automated tests and deployments
- Staging environment for ongoing testing
- Production environment with monitoring (Sentry, Datadog)
- API documentation (Swagger/OpenAPI)
- One-hour handoff session with your team
- Infrastructure-as-code (Terraform) for reproducibility
- Secrets management (AWS Secrets Manager or HashiCorp Vault)
- User documentation for end users (if applicable)

Compliance built in
We have shipped HIPAA, PCI-DSS, SOC 2, and FERPA compliant apps. We build compliance into the architecture from day one, not as an afterthought.
