Hire senior TypeScript developers through Probegin — full-stack engineers who use types as architecture, not decoration. Vetted profiles within days, start within two weeks, 60-day trial.
One language across React/Vue fronts and Node back ends — shared types, shared validation, fewer integration bugs.
tRPC, OpenAPI or GraphQL codegen so the front end can't drift from the back end silently.
Incremental strictness ratchets that convert legacy JS estates without stopping delivery.
Monorepos, ESLint/Biome rules and CI type gates that keep a growing team fast.
TypeScript specialists make sense when the codebase has outgrown tribal knowledge. They usually pair with Reaccionar or Node.js placements — often as the same person.
Bringing scattered JS projects into one typed monorepo with shared contracts.
tRPC/OpenAPI setups so front and back end stop breaking each other silently.
Large refactors made routine because the compiler carries the risk.
Mid to senior full-stack profiles. TypeScript is the connective tissue of our frontend and Node benches, so availability is among the best in the network.

One specialist, embedded in your team, your standups and your tools — the classic direct model. Most placements run this way for a year or longer.
Two or three days a week for maintenance-grade or advisory work — you keep senior capability without paying for idle hours.
For outcome-scoped delivery, the specialist joins one of our implementation pods — priced on the result, not the hours.
Rates depend on seniority, framework scarcity and engagement length. As a public reference point: Dutch IT detachering averages roughly €65–150 per hour (ITRC, 2026); direct nearshore hiring typically lands well below the local top of that band for equivalent seniority, because there is no agency stack in between. You get an exact, all-in rate for your shortlist in the intro call — before you commit to anything.
A 30-minute intake: the role, the stack, the team it lands in, the timeline it has to hit.
Two to three vetted TypeScript developers from our 400K+ European network — within days.
Tú te encargas de las entrevistas y tomas la decisión. Sin presión, no hay ninguna plantilla que tengamos que vaciar.
Nos encargamos de los contratos y de la incorporación. Un periodo de prueba de 60 días, por lo que el riesgo lo asumimos nosotros.
Your TypeScript developers work from our network across the Netherlands, Ukraine, Hungary, Romania, Poland and Bulgaria — all CET ±1, all fluent English (C1), all contracted and payrolled by Probegin so compliance stays our problem, not yours.
Type-driven architecture: API contracts, shared models and refactor safety. On codebases above a certain size, that's the difference between shipping weekly and being afraid of your own code.
Yes — incremental migration with strictness ratchets is a standard engagement; the codebase keeps shipping while types are introduced module by module.
Both. Most TypeScript placements are full-stack: a React or Vue front end plus a Node/NestJS API.
Vetted profiles within days; start within two weeks; 60-day trial period as standard.
Above roughly two developers and two years of expected life, almost always. We migrate incrementally with strictness ratchets, so you never stop shipping to pay for it.
The first 60 days are the proof: if the match isn't right, you say so and the placement ends without long-term obligation — or we replace the profile from the network. Most trials convert; the ones that don't cost you a conversation, not a contract.
Yes — that's the normal growth path. Many clients start with a single specialist and expand to two or five as the roadmap demands, keeping one contract and one point of contact at Probegin. Scaling down is equally simple, with reasonable notice instead of penalty clauses.
Probegin does. You get one Dutch counterparty and one invoice; employment, payroll and cross-border compliance for the specialist are our responsibility. That structure also keeps you clear of freelance-classification risk under Dutch rules.
Tell us the role today, meet your matches this week, have them on the team in two.
