TypeScript
Hire TypeScript developers who type the boundary first
Our engineers have shipped TypeScript across a real-time trivia platform, a clinical matching system, and a multi-branch service dashboard. They design the types at the edges of the system before writing the function inside them.
Who you actually hire
4 things that decide this
- 01Senior engineers who have run TypeScript in production across real-time, healthcare, and multi-role systems, not a course certificate and a portfolio project.
- 02You interview every engineer before they join. Nobody is assigned to your team from a profile you never saw.
- 03They treat `any` as a decision to justify, not a shortcut, and they wire validation to your types instead of maintaining two versions of the same shape.
- 04Every line and every type definition is yours from the first commit.
What a TypeScript developer actually does here
TypeScript does not stop bad code. It stops a shape from silently drifting between the parts of your system that depend on it matching.
On Elevent they typed the Vue.js player app and the Node backend together. A score update over Socket.IO cannot silently change shape between server and screen, across events running from 10 to 1,000-plus players. On TrialTriage they typed the NestJS API and the React frontend against the same patient and trial models. A nurse reviewing a match sees the same fields the database actually stored. On ZhoopZhoop's React dashboard they typed the call, quote, and appointment records streaming in over WebSockets from a Python backend. A payload the server changes fails a build instead of a page.
Different stacks, one repeated decision. Define the shape at the API and the database first. Let every function that touches it inherit the type instead of re-declaring it.
What they take off your roadmap
Types at the boundary, not the leaf
The API response and the database row get typed first. A component prop typed in isolation just moves the bug one file over.
Validation wired to the type, not duplicated
A Zod or Joi schema that generates the type, so the runtime check and the compile-time check cannot drift apart from each other.
`any` treated as a decision
Every escape hatch gets a comment saying why. A codebase where `any` appears without explanation is one nobody has audited in a while.
Fewer runtime surprises at 2am
The class of bug that reaches production as an undefined value at midnight is mostly a type the compiler was never asked to check.
- Database rowThe shape starts here
- API boundaryValidated once, typed once
- Shared typesOne source, not duplicated
- Frontend stateInherits, never re-declares
- Compile checkCatches drift before a user does
Type it at the edge and everything downstream inherits the shape. Type it at the leaf and you have decoration, not protection.

How hiring works
- 01
Tell us what is drifting
A free call about the codebase, the team size, and where bugs keep slipping through review. If the fix is process rather than a hire, you will hear that on the call.
- 02
Meet the engineers
We shortlist people who have typed a real API and database boundary in production, and you interview them yourself, your own way.
- 03
They embed
Your repository, your standups, your pull request process. One of our engineers owns the type coverage on what they touch.
- 04
They hand over
The shared types, the validation schemas, and a note on any `any` left behind and why. The first 2 months of support and maintenance are free, with every build.

Practices
Bring us the bug that only shows up in production
Show us where a shape changed and nothing caught it until a user did. The scoping call is free, and you will leave it knowing whether the fix is types, tests, or both.
01How is this different from posting the role on a job board?
You get an engineer who has already typed a production API and database boundary, plus a company accountable if the fit is wrong. A job board hands you a resume and a hiring risk you carry alone. If our engineer is not right, we replace them, which is not a conversation you have with a contractor you found yourself.
02How do we handle it if the engineer does not fit our codebase?
Say so and we swap them out. You interviewed them yourself, so this is rare, and finding a replacement stays our problem rather than restarting your hiring process.
03What working-hours overlap do we get with our team?
A daily overlap with your hours, agreed before anyone starts. Type design is a conversation during code review, not a ticket handed off overnight. We fix the window during scoping and it does not move without you.
04Who owns the type definitions and the code?
All of it, from the first commit. That includes shared type packages, validation schemas, and any tooling they set up. Your next hire inherits a codebase, not a dependency on the person who left.
05What drives the cost of a TypeScript engagement?
Mostly how far your existing code is from typed. A greenfield build is fast to type correctly from day one. Migrating a large untyped JavaScript codebase, or one with `any` scattered through it, is the work. Scoping calls are free. Where we need to read an existing codebase before answering, a paid two-week diagnostic produces a fixed price instead of a guess.
