Expert Full Stack Software Development ConsultantsFull Stack
We ship your product in 8-12 weeks with a fixed price. Senior engineers build your web app, mobile app, or SaaS MVP from idea to release.
IRPR provides expert full stack software development consultants who build production-ready applications using React, Next.js, Node.js, Python, and PostgreSQL. We handle everything from frontend to backend to cloud infrastructure so you get a working product, not a prototype.
Most projects ship in 8 to 12 weeks with fixed pricing between $80,000 and $250,000 depending on scope. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards when needed. Every project includes a 2-week Roadmap phase where we define the exact scope, tech stack, and timeline before you commit.
Our expert full stack software development consultants work with startup founders who need an MVP to raise seed funding, enterprise teams who want to modernize legacy applications, product managers who require a dedicated engineering squad, and agencies that need white-label development capacity.

Why expert full stack software development consultants matter
One team handles the entire stack so you don't coordinate between frontend, backend, and DevOps vendors.
Expert full stack software development consultants reduce handoff delays by 40% compared to using separate specialists. You get a single point of contact who understands how the database schema affects the React component tree and how the API endpoints map to the mobile app screens.
IRPR's senior engineers have an average of 10 years of experience across the full stack. They work async-first with 4 hours of daily overlap with US time zones. Every project uses a shared codebase in a private GitHub repo with CI/CD via GitHub Actions.
Generic dev shop vs expert full stack consultants
Not all consultants deliver the same outcome. Here is what you get with IRPR.
Generic shops often assign junior engineers and change scope mid-project. They bill hourly and have no fixed timeline. You end up with a half-finished product that costs 2x the original estimate.
IRPR uses only senior engineers with 10+ years of experience. Every project starts with a 2-week Roadmap where we define the full scope, timeline, and fixed price. No hourly billing. No scope creep.
- junior and mid-level engineers on your project
- hourly billing with no price cap
- no written scope before build starts
- you coordinate between frontend, backend, and DevOps teams
- no compliance documentation (HIPAA, PCI, SOC 2)
- you own no code until final payment
- senior engineers only (average 10+ years)
- fixed price from the Roadmap phase
- scope documented in a spec before any code is written
- one team handles frontend, backend, cloud, and testing
- built-in compliance for HIPAA, PCI-DSS, SOC 2
- you own the full source code from day one
How our expert full stack consultants deliver your project
Four phases from idea to release. No wasted sprints.
We break every engagement into four clear phases. Each phase has a fixed duration and a specific deliverable. You see progress every week.
By week 12, you have a production-ready application deployed to your own AWS account with CI/CD, monitoring, and documentation.
What ships with every engagement
Every deliverable is concrete and usable. No empty repos.
When we finish, you own everything that was built. No locked-in contracts, no recurring fees for code access.
Our expert full stack software development consultants ensure you can maintain the application yourself or hand it to any internal team.
- Full source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Production deployment on AWS ECS or GCP Cloud Run
- Sentry error tracking configured
- PostgreSQL database with migration scripts
- REST API documentation (OpenAPI 3.0)
- MySQL or MongoDB schema diagrams (dbdiagram.io)
- Admin panel for managing users and data
- 2-week warranty for bug fixes post-launch
- Written handover guide with credentials list
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly billing
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 total cost before we write a single line of code.
Senior engineers only
IRPR does not use junior or mid-level developers. Every engineer has at least 10 years of experience with modern full stack frameworks like Next.js, Node.js, and AWS. You get a lead engineer, not a team of interns.
8-12 week delivery guarantee
Our average MVP ships in 12 weeks. We use time-boxed phases and only commit to what fits the timeline. If we miss the deadline, we work extra days at no cost. 98% of our projects finish on time.
Full code ownership from day one
You own the source code, the repository, and the infrastructure from the first commit. There is no licensing fee or ongoing payment to IRPR for code access. You can take the project anywhere.
Built-in compliance (HIPAA, PCI, SOC 2)
We design applications with compliance from the start. For healthcare: HIPAA BAA and audit logs. For payments: PCI-DSS tokenization via Stripe. For enterprise: SOC 2 controls. No afterthoughts, no retrofitting.
Async-first but US timezone overlap
Our team works async with a 4-hour daily overlap with US business hours. You get daily Slack updates, weekly video calls, and a shared project board (Linear or Jira). No waiting 24 hours for a response.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
