Looking to hire TypeScript developers who use the type system, not just `any` everywhere? Many developers add TypeScript to a project and then quietly defeat it with loose types and ignored errors. Our TypeScript developers model your domain with types so the compiler catches bugs before they reach production.
The value of TypeScript shows up at scale: large codebases, many contributors, and frequent refactors. That is exactly where weak typing hurts, with generics done wrong, types that lie about runtime values, and `strict` mode disabled to make errors go away. Our developers write types that stay honest, lean on generics and discriminated unions, and keep the build green under strict settings.
Whether you need a TypeScript developer to harden an existing codebase, migrate from JavaScript, or build a new typed product, we offer flexible engagement models. With 534+ projects delivered and 6+ years of experience, your developer can start within 48 hours.

Why Hire Through Us
Benefits of hiring developers through Hevcode
Pre-Vetted TypeScript Talent
Every TypeScript developer is tested on real typing problems: generics, narrowing, and strict mode, not just adding type annotations. You get genuine type-system depth.
Developers Start in 48 Hours
Skip the long search for strong typed-codebase hires. We match you with a TypeScript developer who can start contributing within 48 hours.
Flexible Hiring Models
Hire a dedicated TypeScript developer, a full managed team, or hourly and part-time help. Scale up for a migration and down for maintenance.
Direct Communication
Work directly with the TypeScript developer shaping your types and architecture. No middle layer between your requirements and the code.
4+ Hours Timezone Overlap
Your TypeScript developer keeps at least four hours of daily overlap for live pairing on type design, code reviews, and standups.
1-Week Risk-Free Trial
Start with a one-week risk-free trial. If the TypeScript developer is not the right fit, you pay nothing and we rematch you.
Engagement Models
Flexible hiring options to match your needs
Dedicated Developer
A full-time TypeScript developer owning your typed codebase, keeping strict mode green, modeling your domain in types, and refactoring with confidence as the product grows.
Ideal for: Large React or Node codebases, teams scaling contributors, long-term products
Development Team
A fully managed team of TypeScript developers with a QA engineer and lead. We deliver a strictly typed, tested codebase with shared types across client and server.
Ideal for: Full-stack TS products, monorepos, end-to-end typed delivery
Hourly/Part-Time
Pay only for the hours you use. Ideal for migrating JavaScript to TypeScript, fixing type errors, designing generics, or tightening a loose codebase to strict mode.
Ideal for: JS-to-TS migration, type hardening, tooling setup, consulting
Hiring Process
Simple 4-step process to get your developer
Share Requirements
Tell us about your codebase, whether React, Node, or both, your TypeScript maturity (new, partial, or strict), and whether you need a build, a migration, or hardening.
Developer Matching
Within 24 hours we present 2-3 pre-vetted TypeScript developers whose experience matches your stack, strictness goals, and project stage.
Interview and Select
Interview the candidates on type design and real-world typing problems, review their work, and choose the developer who fits your team and codebase.
Start Building
Your TypeScript developer onboards within 48 hours. We set up repo access, tooling, and communication so they ship typed code in the first sprint.
Frequently Asked Questions
Common questions about hiring developers
How deep is your developers' TypeScript knowledge?
Our TypeScript developers go well beyond annotations. They are fluent in generics and constraints, discriminated unions, conditional and mapped types, type guards, and strict compiler configuration. They have shipped large React and Node codebases where strong typing was essential to staying maintainable.
Can your developers migrate our JavaScript project to TypeScript?
Yes. We run incremental JS-to-TS migrations that keep your app shipping the whole time: enabling TypeScript with allowJs, converting files in priority order, replacing any with real types, and tightening tsconfig toward strict mode without a risky big-bang rewrite.
How quickly can a TypeScript developer start?
A selected TypeScript developer can onboard within 48 hours, and often 24 for urgent needs. Their TypeScript and tooling environment is ready, so they can build and type-check your project on day one.
What if the TypeScript developer isn't the right fit?
You start with a one-week risk-free trial. If the developer is not the right fit for your codebase or team, you pay nothing and we replace them at no cost. After the trial we can still swap developers with one week of notice.
How do you ensure type safety and code quality?
Our developers keep strict mode on, avoid escape hatches like any and unchecked assertions, validate external data at runtime with Zod, and enforce typescript-eslint rules. They keep the build type-clean and write tests so types and runtime behavior stay in agreement.
Can I scale up to a full TypeScript team later?
Yes. Start with one dedicated TypeScript developer and add more, or move to a fully managed team with QA and a lead. We keep a bench of pre-vetted TypeScript talent so you can scale from one developer to a full-stack typed team without restarting your hiring.
