Overview
Hire TypeScript developers who actually use the type system instead of tolerating it. Most 'TypeScript developers' are JavaScript developers with a tsconfig file. Ours write generic functions that compose, conditional types that catch real bugs, branded types that prevent ID-mixing, and discriminated unions that make impossible states impossible. We use TypeScript across the stack: React, Node.js, tRPC, Drizzle, Zod. The result is fewer runtime bugs, faster onboarding, and refactors that complete in hours instead of days.
Why Techyor.
Senior. Specialist. Shipping.
Strict mode, no escape hatches
We enforce strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes. We don't smuggle in `any`. Types are a force multiplier, not a tax.
Type-safe across the stack
tRPC, Drizzle, Zod give us end-to-end type safety from database to UI. A schema change reveals every site that needs updating before we ship.
Advanced types in production
Generics, conditional types, mapped types, type predicates — used pragmatically to model real domain logic, not as an academic exercise.
What they cover.
Skills and stack.
Capabilities

How you can hire.
Three ways to engage.
Dedicated Full-Time
A senior developer working exclusively on your product, embedded into your team, sprint cycle, and rituals. Best for roadmap-driven work with continuous shipping.
Part-Time / Fractional
Two to three days a week of senior expertise. Ideal for early-stage teams, technical advisory, code review, or supplementing an existing in-house team.
Fixed-Scope Project
Defined milestones, outcomes, and timeline. Best when the brief is clear and you want a predictable budget. Includes design, QA, and handover.
A two-week, no-risk trial.
Work with your typescript developer for two weeks. If it is not the right fit, we replace them free or you walk away owing only for work delivered. After that it is month-to-month — no long contracts, and your code, accounts, and IP are always yours.
In-house vs Techyor.

FAQ.
Common questions.
Should I hire dedicated TypeScript developers or a JavaScript team?
Hire dedicated TypeScript developers when type safety has real business cost: contracts crossing service boundaries, mobile and third-party API consumers, large refactors on the roadmap, or a team big enough that the next dev shouldn't have to read every file to understand a function signature. A JavaScript team will ship working code; a dedicated TypeScript developer will ship code where the next refactor is a 30-minute IDE-led job instead of a week of regression hunting. The payoff compounds the longer the codebase lives.
How is hiring a senior TypeScript developer different from a JavaScript developer who uses TS?
Three things separate senior TypeScript work from JavaScript-with-types. First, type-system literacy — knowing when a conditional type is the right tool and when it's premature, when generics earn their complexity. Second, runtime/compile-time discipline — pairing types with schema validation (Zod, Valibot) so the type system protects what the runtime actually sees. Third, refactor instinct — building APIs whose shape a TypeScript-aware editor can refactor across a 50k-line codebase in seconds. A senior TypeScript developer turns 'we should rename this field' from a sprint into a commit.
Can I hire TypeScript developers from India for a US or UK product?
Yes — most of our clients are in the US, UK, EU, and Australia. We overlap with East Coast US morning and UK afternoon hours, run async-first with daily standups, and ship in your timezone's calendar. Senior India-based TypeScript developers cost 40–60% less than equivalent senior engineers in the US or UK without quality compromise. We've shipped strict-mode codebases, tRPC monorepos, and JavaScript-to-TypeScript migrations across all four regions.
How strict is your strict mode?
All eight strict flags + noUncheckedIndexedAccess + exactOptionalPropertyTypes + noPropertyAccessFromIndexSignature. We turn on whatever the codebase can sustain — and migrate incrementally if needed.
tRPC or REST + types?
tRPC when frontend and backend are in one TypeScript repo and the team controls both. REST + Zod schemas + generated client when the API has multiple consumers (mobile, third-parties).
Should I migrate my JavaScript codebase?
Usually yes — incrementally. Add `tsconfig.json`, allow JS, convert highest-traffic files first, tighten compiler options gradually over months. Net positive in 3–6 months for most non-trivial codebases.
Drizzle, Prisma, or Kysely?
Drizzle for SQL-aware teams that want type-safe queries close to SQL. Prisma for teams wanting maximum DX with migrations included. Kysely for query-builder fans. We do all three; choice is project-dependent.
What about runtime validation?
Zod by default — mature ecosystem, integrates with tRPC and most frameworks. Valibot for bundle-size-critical edge functions. Effect Schema for codebases adopting Effect.
Generics — when do they pay off?
When you have multiple call sites with structural similarity and type variance. Don't reach for generics first; refactor to them when duplication shows up.
How fast can a developer start?
For most roles, within 5–10 business days from the intro call. We pre-qualify our bench so onboarding is contracts and access — not a hiring search.
Do you sign NDAs and IP assignment agreements?
Yes — every engagement starts with a mutual NDA and a clean IP assignment clause. All work product is your property the moment it's written.
What time zones do your developers cover?
Our team primarily operates in IST with 4–6 hours of overlap with US Pacific, full overlap with EU, and full overlap with AU East. We commit to overlap windows in writing.
What if the developer is not the right fit?
There is no long lock-in. The first two weeks are a no-risk trial: if a developer is not the right fit, we replace them at no cost or you walk away owing only for work delivered. After that, engagements are month-to-month with 30 days notice — you are never trapped in a contract, and your code, accounts, and IP are always yours.
