TypeScript development
We build in TypeScript end to end — one type system across the browser and the server, schemas as the contract between them — so whole categories of runtime surprise never reach production.
TypeScript's value is not decoration; it is a proof, checked on every save, that the shapes flowing through a program are the shapes the program expects. A field that might be null, a response missing a key, a refactor that forgot one call site — the compiler catches these before a user ever does. On a codebase of any size, that is the difference between a change you can make with confidence and one you make with your fingers crossed.
We write it on both sides of the wire. React and Next.js on the front, Fastify and Node on the back, with the API schema shared so a change to a response type shows up as a compile error in the UI rather than a bug in the field. Every Ekarche product is built this way — Lekha and Koryvant included — because end-to-end types are what let a small team move quickly without breaking what already works.
What end-to-end types buy you
-
Types across the boundary
Shared types from the database to the UI, so the front end and back end agree by construction — a mismatched shape is a compile error, not a production incident.
-
Schemas as the contract
Runtime schemas — TypeBox, Zod, Pydantic on the Python side — that validate at the edge and generate the static types, one definition doing the work of three.
-
Refactors you can trust
Rename, move, and restructure with the compiler tracking every call site — the safety that lets a codebase keep changing without quietly rotting.
