Its frontend stack includes TypeScript, React, Next.js, Redux, HTML, CSS, and Tailwind, while backend projects can use TypeScript with Node.js, NestJS, Express, TypeORM, and Sequelize. This gives the team the ability to keep TypeScript within a product from the interface through server-side logic.

The wider delivery process also covers business analysis, UX/UI, QA, infrastructure, and post-launch support. Gilzor has European offices in Warsaw and Limassol.

SysGears has a dedicated TypeScript development practice covering consulting, custom applications, frontend and backend engineering, mobile development, and JavaScript-to-TypeScript migration. Its stack combines TypeScript with React, Next.js, Node.js, Express, and NestJS, while supporting tools include GraphQL, Prisma, TypeORM, Jest, Playwright, and Cypress.

The company offers full-cycle development, dedicated teams, and team augmentation, making it relevant to both new software products and existing applications that need modernization or additional engineering capacity. SysGears lists European locations in Cyprus, Ukraine, and Poland.

A-listware combines custom software development with dedicated teams and engineering outsourcing. TypeScript is explicitly included among the technologies supported by the company, together with Node.js and other backend and frontend technologies.

This delivery model is particularly relevant when a company already has its own product organization but needs additional developers for an existing TypeScript codebase. A-listware also provides broader software services for web portals, ecommerce products, collaboration systems, analytics solutions, and enterprise applications. The company maintains a UK office in St. Leonards-On-Sea.

The company also maintains its own TypeScript and Node.js tooling for software projects.

Its current service portfolio includes web development, modernization, cloud engineering, product design, mobile development, and dedicated engineering teams. This makes The Software House relevant to established products where TypeScript development needs to be combined with architecture, cloud, or long-term modernization work.

OSKI Solutions provides dedicated TypeScript development across React, Angular, Vue.js, Next.js, Node.js, and NestJS environments. Its TypeScript work includes type-safe frontend development, Node.js backends, shared API contracts, and incremental migration of existing JavaScript applications.

Itexus develops financial and fintech software, with TypeScript included in its enterprise technology stack and project portfolio. Its current technology guidance lists TypeScript as an option for backend APIs, business logic, and microservice architectures, while its portfolio includes NestJS and TypeScript alongside React, .NET, Azure, and other technologies.

Monterail is closely associated with the Vue.js and Nuxt ecosystem, making it particularly relevant when TypeScript is being used in Vue-based applications. The company is an official Vue.js partner and has also become a Nuxt partner. Its current technical materials cover TypeScript integration for Vue and Nuxt applications, including type-safe client and server-side development.
