Senior Full Stack App Development CompanyFull Stack
We build custom apps with senior engineers. 8-12 week MVPs with fixed pricing, no hourly billing.
IRPR is a senior full stack app development company. We build web and mobile apps using React, Node.js, Python, Go, and PostgreSQL. Every engineer has 8+ years experience and ships production code from day one.
Most MVPs ship in 8-12 weeks for $80K to $250K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2). You get a fixed price after the Roadmap phase, not a vague estimate.
Founders who need a technical co-founder hire us because they want a real product, not a prototype. CTOs at Series A startups outsource their core platform to us because we move faster than their in-house team. Enterprise innovation teams use us to build new products without hiring 5 senior engineers.

Why Choose a Senior Full Stack App Development Company
Most software shops assign junior devs to your project. We do not. Every engineer on your project has 8+ years of experience and has shipped at least 10 apps before yours.
IRPR was founded to fix a broken model. Generic agencies put one senior architect in front of clients and then staff the project with junior developers who learn on your dime. We did the opposite: we only hire senior engineers. That means your app gets architected correctly from day one, not rewritten three times.
Our senior team delivers in 8-12 weeks what takes other shops 6 months. With 200+ products shipped across 50 countries, we have patterns for auth, payments, real-time data, and compliance that we reuse and customize. You do not pay for our learning curve; you pay for our speed.
Senior Developers vs Generic Dev Shops
You have two choices: hire a shop that assigns one senior and three juniors, or hire IRPR where every engineer is senior. Here is the difference.
Generic dev shops look good on paper. They have case studies, a nice website, and a sales team that promises the world. But when the project starts, you discover the lead architect is on 3 other projects, and the actual coding is done by a junior who learned React last year.
IRPR does not hire juniors. Period. Every engineer has held a senior title at a product company or a FAANG before joining us. Your project gets dedicated senior attention, not a rotating cast of junior devs.
- One senior architect, three junior devs
- Hourly billing with no cap
- 6-12 month delivery timeline
- Unfamiliar with your industry compliance
- Code ownership disputed in contract
- Offshore team with timezone delays
- All senior engineers, 8+ years experience
- Fixed price after Roadmap phase
- 8-12 week MVP delivery
- HIPAA, PCI-DSS, SOC 2, SOC 3 ready
- Full source code ownership from day one
- Async-first with 4+ hour daily overlap with US
Our Process for Building Your Full Stack App
From idea to release, we follow four phases. Each phase ends with a clear deliverable and a go/no-go decision. No surprises.
Phase 1 is the Idea validation call. We spend 2 hours understanding your market, your users, and your constraints. You walk away with a clear yes or no on feasibility. If we proceed, Phase 2 is the Roadmap.
Phase 2 takes 1-2 weeks and produces a documented product roadmap, a fixed price quote, and a detailed timeline. You approve the roadmap, and we start building. Phase 3 is the 8-12 week build sprint. Phase 4 is release and ongoing support at $8K/month.
Everything You Get with Every Project
When you hire IRPR as your senior full stack app development company, these items ship by default. No add-ons, no upsells.
Every project includes the following deliverables. You own everything from day one.

Why teams hire us.
All Senior Engineers, No Juniors
Every developer on your project has 8+ years of experience. We do not hire junior devs. Your code is written by people who have built and scaled apps before, not people who are still learning.
Fixed Price, Not Hourly Billing
After the Roadmap phase you get a fixed price quote. No hourly billing, no surprise invoices, no scope creep charges. The price you agree on is the price you pay.
8-12 Week MVP Delivery
Most MVPs ship in 8-12 weeks. Our senior team moves fast because we reuse patterns for auth, payments, and deployment. You do not pay for our learning curve.
Full Code Ownership
You own every line of code from day one. We push to your GitHub repo, not ours. No license fees, no IP disputes, no vendor lock-in.
Compliance Built In, Not Bolted On
HIPAA, PCI-DSS, SOC 2, FERPA, and SOC 3 compliant by default. We have pre-audited infrastructure templates and handle BAA signings for healthcare clients.
Async-First with US Overlap
Our team works async across time zones but guarantees 4+ hours of daily overlap with US hours (EST/PST). You get daily status updates via Slack, not weekly email summaries.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
