Overview
Hiring a 'TypeScript developer' usually means hiring a JavaScript developer who tolerates TypeScript. Ours don't tolerate it — they use it. They 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
- TypeScript 5.x — strict mode, noUncheckedIndexedAccess, exactOptionalPropertyTypes

- Schema validation — Zod, Valibot, Effect
- Type-safe ORM — Drizzle, Prisma, Kysely
- TypeScript ESLint — typescript-eslint with type-aware rules
- Build tooling — tsc, esbuild, swc, tsup
- Migration — JavaScript to TypeScript, weak types to strict

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.
How it works.
Simple. No theatre.
- 01
Quick intro call
A 30-minute conversation. Tell us what you're building, the stack you're on, and where you'd like help. No deck, no obligation.
- 02
We share our experience
We walk you through relevant projects we have shipped, the approach we would take, and the trade-offs to expect. Honest about what we are great at — and what we are not.

Start work
Mutual NDA, a clear scope, and a start date. We begin shipping that week. Daily updates and a single point of contact throughout.

FAQ.
Common questions.
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.
