Why hire senior full stack software development consultants
You get a dedicated senior engineer who delivers production code, not just advice.
IRPR's senior full stack consultants average 10+ years of experience. They have shipped over 200 products across 50 countries. Each consultant is a full-stack generalist who can handle frontend, backend, DevOps, and cloud infrastructure.
We use a proven 4-phase framework: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2) we produce a fixed-price quote and a detailed technical plan. The Product phase builds your MVP in 8-12 weeks with daily standups and weekly demos.
The difference between generic developers and senior full stack consultants
Not every developer is a consultant. Our senior engineers bring architecture design, compliance knowledge, and product thinking.
Generic development shops assign junior or mid-level developers who follow specs. They often lack the experience to make architectural decisions or handle security compliance. You get code that works but may not scale or pass a security audit.
IRPR assigns senior full stack software development consultants who have built and deployed complex systems. We handle everything from CI/CD pipelines to HIPAA compliance. Our consultants act as technical partners, not just coders.
- Junior to mid-level developers assigned
- Hourly billing with unpredictable costs
- No dedicated architecture review
- Basic security (no compliance expertise)
- Code delivered without CI/CD or monitoring
- Minimal communication after project start
- Senior engineers with 10+ years experience
- Fixed price for entire project scope
- Architecture design in Roadmap phase (week 2)
- HIPAA, SOC 2, PCI-DSS compliance built in
- CI/CD pipeline, error tracking, and uptime monitoring included
- Weekly demos and Slack support throughout build
How our senior full stack consultants deliver your project
Our framework moves from concept to production in 4 phases, each with clear deliverables.
We start with a 1-2 week kickoff where we align on goals, tech stack, and timeline. Then we move into the Roadmap phase, producing a detailed specification and fixed-price contract. The Product phase is where we build and test your MVP. Finally, Release includes deployment, documentation, and handover.
During the build, you get a dedicated project manager and the senior consultant working on your code. We use agile sprints, two-week cycles, and a shared Jira board. Code is stored in your private GitHub repository from day one.
What ships with every senior full stack engagement
You own everything. No black boxes, no hidden dependencies.
Every project comes with a complete delivery package. We don't just hand over code. We give you the tools to run, monitor, and improve your product. This includes infrastructure as code, documentation, and a deployment playbook.
If you need compliance, we also provide evidence controls like audit logs, encrypted data storage, and role-based access. All deliverables are reviewed by our senior team before handoff.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Production deployment on AWS, GCP, or Azure
- Sentry error tracking and performance monitoring
- PostgreSQL database with automatic backups
- API documentation using Swagger or Postman
- Docker configuration for local development
- User authentication (JWT, OAuth, or SAML)
- SSL/TLS certificate and domain configuration
- One-year warranty on code defects
