Senior TypeScript Software Development ConsultantsDevelopment Consultants
Hire senior TypeScript software development consultants who build production systems in 8-12 weeks. 200+ products shipped to 50+ countries.
IRPRs senior TypeScript software development consultants build full stack applications with TypeScript, React, Next.js, Node.js, Express, and PostgreSQL. We design type-safe APIs, manage state with Zustand or Redux Toolkit, and deploy on AWS or Vercel using CI/CD pipelines.
Our TypeScript consultants deliver production-ready software in 12-14 weeks. Projects start at $80K and go up to $250K for enterprise systems. Every engagement includes fixed pricing, source code ownership, and compliance standards like SOC 2 or HIPAA when required.
We work with CTOs at funded startups who need to ship a TypeScript MVP in 12 weeks. Engineering VPs at mid-market companies who want to modernize legacy JavaScript codebases with TypeScript. And product managers at enterprise orgs who need senior TypeScript software development consultants to build a new SaaS platform.

Why senior TypeScript software development consultants matter
TypeScript prevents entire categories of bugs. Our consultants enforce strict types from day one.
Static typing catches errors at compile time, not runtime. TypeScript reduces production bugs by 40-50% according to a 2020 study by UiPath. Every IRPR consultant sets noImplicitAny and strictNullChecks from the first commit. No any statements allowed.
Type safety speeds up refactoring. When your codebase grows to 50,000 lines, changing a data shape without TypeScript takes weeks of manual testing. With our TypeScript architecture, a single type change propagates across 200 files in seconds. The compiler tells you exactly what broke.
The difference between generic JavaScript shops and IRPRs TypeScript consultants
Most agencies say they use TypeScript but allow any and implicit any. Our consultants enforce strict mode.
Hiring senior TypeScript software development consultants means paying for discipline. Every IRPR project starts with a custom tsconfig.json. We set strict mode, noUnusedLocals, noUnusedParameters, and exactOptionalPropertyTypes. No exceptions.
Generic dev shops treat TypeScript as a linter. We treat it as a contract enforcement tool. Each function signature declares exactly what goes in and out. Unit tests verify behavior. End to end tests with Playwright validate the full stack. You get a codebase that compiles cleanly and runs reliably.
- Allows implicit any in 30% of files
- No strict null checks
- SkipLibCheck set to true
- No automated type coverage reporting
- Mixed JavaScript and TypeScript files
- No code generation for types
- Strict mode on every project
- TypeScript 5.x with exactOptionalPropertyTypes
- Type coverage reports via type-coverage npm package
- 100% TypeScript codebase, zero JS files
- Automated type generation from OpenAPI and GraphQL schemas
- Custom ESLint rules enforcing type imports
How we engage as your TypeScript consultants
Our senior TypeScript software development consultants follow a 4 phase discovery and build process.
Phase 1 is free and takes 1 week. We audit your current codebase or requirements, review your TypeScript usage, and estimate effort. No commitment.
Phase 2 is the Roadmap. We produce a fixed price quote, a 12 week build plan, and full architectural design with typed classes and interfaces. You approve before any code is written.
What ships with every TypeScript engagement
Every project from IRPRs senior TypeScript software development consultants includes these deliverables.
You own everything. Source code in your GitHub repo. Automated CI/CD on GitHub Actions. Monitoring with Sentry and Datadog. Documentation in Markdown.
No black boxes. Every dependency is declared in package.json. Every environment variable is documented. Every API route has typed request and response schemas.
- Source code in your private GitHub or GitLab repo
- TypeScript 5.x with strict mode and noImplicitAny
- CI/CD pipeline with GitHub Actions, ESLint, Prettier, and Jest
- Sentry error tracking with source maps and release tagging
- PostgreSQL or DynamoDB schema with typed migrations
- OpenAPI or GraphQL schema with auto generated type definitions
- Storybook for UI components with TypeScript props documentation
- Unit tests with 80%+ coverage for business logic
- End to end tests with Playwright for critical user flows
- Infrastructure as code with AWS CDK or Terraform

Why teams hire us.
Only senior TypeScript engineers
Every consultant has 8+ years of TypeScript and JavaScript experience. We do not outsource to juniors. Each person has built and maintained production systems with 10,000+ users.
Fixed price, not hourly
After the Roadmap phase, every project gets a fixed quote. No hourly billing, no time tracking, no surprises. You know the cost before we write a single line of TypeScript.
Strict type enforcement from day one
IRPR enforces strict TypeScript mode on every engagement. We set noImplicitAny, strictNullChecks, and exactOptionalPropertyTypes. Type coverage reports are part of the CI pipeline.
Full ownership and transparency
You own the source code, the CI/CD pipeline, and the infrastructure. There are no proprietary libraries or black box modules. Every dependency is declared in package.json with SemVer ranges.
Production support included
Every project includes 30 days of production monitoring and bug fixes after launch. We set up Sentry, Datadog, and uptime alerts. Your team can take over or we can continue support.
Compliance from the start
IRPR builds TypeScript applications for HIPAA, PCI DSS, SOC 2, and FERPA environments. Compliance is not an afterthought. We design audits and logging into the architecture from sprint 1.
Idea → Roadmap → Product → Release.
