Zencloud TechnologiesZencloud Technologies
Hire TypeScript developers who have shipped typed code in production, not just passed a syntax quiz. Zencloud matches you with pre-vetted TypeScript engineers for React, Next.js, and Node.js products, and you interview 2–3 candidates within 24 hours.
Most teams come to us with one of three problems. A JavaScript codebase that breaks every time someone refactors. A roadmap that needs senior engineers faster than in-house hiring allows. Or a TypeScript migration that keeps losing to feature work.
Every developer we place is tested on typed code, works inside your tools and sprints, and is backed by a Zencloud delivery manager. If the fit is wrong, we replace them.

Every TypeScript developer is a JavaScript developer, but the reverse isn’t true. Renaming files to .ts is easy. Designing types that stop bad data at the edges of your system is the skill you’re paying for.
| Your situation | A JavaScript developer | A TypeScript specialist |
|---|---|---|
| Marketing site or small internal tool | Enough | Not needed |
| Three or more engineers in the same codebase | Risky, conventions drift | Shared types act as the contract between people |
| Frontend and backend share data models | Bugs hide in the gaps | One set of types across client, API and server |
| Migrating a large JavaScript codebase | Renamed files, same bugs | A typing strategy, rolled out in stages |
| Integrating LLM, payment or banking APIs | Untyped responses fail silently | Responses validated with Zod and typed SDKs |
| Big refactors on this year’s roadmap | Slow and fragile | The compiler shows every place a change lands |

Component libraries with typed props, Next.js server components, and strict typing across forms and state with Redux Toolkit, Zustand or TanStack Query. If you need a framework specialist first, we also place dedicated React.js developers and Vue.js developers.
REST and GraphQL services built on NestJS, Express, or Fastify, with typed database access through Prisma, Drizzle, or TypeORM. For backend-only roles, see our Node.js developers.
Types defined once and shared everywhere: tRPC for TypeScript-only stacks, OpenAPI or GraphQL Codegen for public APIs, and Zod schemas that check data at runtime as well as at compile time. It’s the same contract-first thinking behind API-first SaaS architecture.
Incremental conversion that keeps your release schedule intact. The full playbook is below.
Turborepo or Nx with pnpm workspaces, shared type packages, and project references that keep type-checking fast as the codebase grows.
LLM features built with the Vercel AI SDK, LangChain.js, and the OpenAI and Anthropic SDKs, with typed tool calls and validated model outputs. Planning a bigger AI project? Start with our 14-day AI Audit to scope it before you hire.
Only the top 3% of applicants make it into our network. Each candidate is tested on real TypeScript work before you ever see their profile:
We look for typed applications they’ve shipped to real users, not course certificates or tutorial projects.
Real scenarios covering type system design, typed APIs and production-scale codebases.
A senior engineer reviews your product goals and technical requirements, then picks candidates who fit your project, not just your keyword list.
| Level | Typical experience | What they own on your team |
|---|---|---|
| Mid-level | 2–4 years of production TypeScript | Features end-to-end, inside your existing typing conventions |
| Senior | 5+ years, including typed APIs and migrations | Type architecture, code review standards, migration plans |
| Lead or architect | 8+ years across several shipped products | Monorepo design, cross-team contracts, mentoring |

Rates fall between $30 and $120 per hour, depending on seniority, specialization, and engagement length.
Big-bang rewrites stall. We migrate in small, shippable steps, so feature work never stops.
Turn on allowJs and checkJs, then count the errors the compiler finds today. That number becomes your baseline.
API clients, database models and third-party SDK wrappers get types and Zod schemas before anything else. This is where most production bugs come in.
Utilities and components with no internal dependencies move to .ts first, then the work moves inward.
tsc --noEmit runs on every pull request, so no new untyped code gets merged.
Enable noImplicitAny, then strictNullChecks, then full strict, fixing errors module by module.
Track the remaining any and @ts-ignore counts in CI, with a target for each sprint.
One senior TypeScript developer can run this alongside your team while feature work continues.
Tell us your stack and timeline, and we’ll shortlist 2–3 matched developers within 24 hours.
A short form and a 30-minute call cover your stack, codebase size, and the gaps on your team.
Each comes with a summary of their TypeScript work that’s relevant to your project. You run the interview.
We handle contracts, onboarding, and admin, so work can begin as soon as you approve.
Add developers, switch to a team pod, or scale back as the work changes.
| Model | Best for | How it works | Billing |
|---|---|---|---|
| Dedicated developer | Ongoing product work | One TypeScript engineer, full-time on your roadmap and in your sprints | Monthly |
| Part-time or hourly | Migrations, code audits, overflow work | A fixed number of hours each week | Hourly, $30–$120 |
| Team pod | New builds or large migrations | Several engineers plus a delivery manager | Monthly per pod |

All three run under our dedicated staff augmentation model. The engineers work on your roadmap, and Zencloud handles hiring, payroll, and admin. Not sure whether to augment your team or hand off the whole project? Our comparison of staff augmentation vs outsourcing walks through both.
Marketplaces hand you a list of profiles and leave the vetting to you. Large agencies add account managers and long scoping phases. We sit in between: engineering-led vetting, a fast match, and direct access to our technical leadership when something needs a decision.
| Zencloud | Freelance marketplace | Large outsourcing agency | In-house hire | |
|---|---|---|---|---|
| Typical time to first interview | 24 hours | Days, then your own screening | Weeks of scoping first | Often 1–2 months |
| Who vets the developer | Our senior engineers, on typed code | You | The agency, often generalists | You |
| Who manages day-to-day | You lead, a delivery manager supports | You | The agency’s project manager | You |
| If the fit is wrong | We replace the developer | You start over | Slow and contract-dependent | You restart hiring |
| Cost structure | Hourly or monthly, priced upfront | Hourly, plus your vetting time | Project fees plus overhead | Salary, benefits, and recruiting fees |

Zencloud TypeScript developers cost $30 to $120 per hour, depending on seniority, specialization and engagement length. Dedicated full-time developers are billed monthly. You see each candidate’s rate before anything starts.
You interview 2–3 matched candidates within 24 hours of your scoping call. Once you pick one, most developers start within 1–2 weeks, after contracts and repo access are in place.
Yes. We migrate incrementally: type the API boundaries first, convert leaf modules, add a type-check gate in CI, then tighten strict mode in stages. Your team keeps shipping features throughout the migration.
Yes. Our developers work across React, Next.js, Angular and Vue 3 on the frontend, and Node.js with NestJS, Express, or Fastify on the backend. Many are full-stack and share one set of types across client and server.
Hire a TypeScript specialist if several engineers share a codebase, your frontend and backend share data models, or you’re integrating payment, banking or LLM APIs. For a small marketing site or internal tool, a JavaScript developer is usually enough.
Tell your Zencloud delivery manager. We review the issue with you and, if needed, replace the developer with a new matched candidate, so your project keeps moving.
